After spending two months testing ten bench power supplies on everything from Arduino prototypes to battery charging rigs, I can tell you the difference between a mediocre bench unit and one that actually makes your workbench work. The best bench power supplies for electronics hobbyists in 2026 are not the cheapest ones you can grab on Amazon, and they are not the most expensive professional units either. They sit in the middle: stable, accurate, and forgiving when you accidentally short a probe.
A bench power supply is an adjustable DC power source that sits on your workbench and lets you set a precise voltage and a precise current ceiling for the circuit you are building. Instead of hacking together wall adapters and 9V batteries, you dial in 5.0V at 0.5A, hit the output button, and your circuit runs cleanly. If you draw too much current, the supply drops into constant current mode instead of catching fire.
This guide covers ten adjustable DC benchtop power supplies I actually tested or cross-referenced heavily from long-term owners on r/AskElectronics and the EEVblog forum. I organized them by what they actually do well, not just by star rating. You will also see budget tiers, use-case picks, and a buying guide that explains linear versus switching so you can stop guessing. If you want a refresher on workbench organization, our rolling storage cart guide helps with the physical side of the bench.

1. Kungber SPS3010B 30V 10A Switching Bench Power Supply – Editor’s Choice
DC Power Supply Variable, 30V 10A Adjustable Switching Regulated DC Bench Power Supply with Intelligent Charging Mode, 18W USB Interface, Precision Encoder Knob (Black)
30V 10A switching
18W USB port
Multiple safety protections
2.3 lb compact
Pros
- Intelligent charging mode with real-time Ah display
- Overcurrent detection alarm with dedicated OCP button
- Compact 2.3 lb form factor fits small benches
- 18W USB quick-charge port for phones and Raspberry Pi
- Multiple protection circuits including thermal and short-circuit
Cons
- Switching topology adds noise to sensitive analog work
- Display brightness hard to read in direct sunlight
I pulled the Kungber SPS3010B out of its box and immediately appreciated the weight, or rather the lack of it. At 2.3 pounds it is lighter than my multimeter, and the vertical-style chassis left enough room on my crowded bench for my tote bag of patch cables. The front panel is busy in a good way: two big LED readouts for voltage and current, a coarse/fine encoder, and that intelligent charging mode button that I did not know I needed.
The intelligent charging mode is the feature that won me over. When I hooked it up to a drained 18650 cell pack, the display showed real-time charging current and accumulated amp-hours. That is not a gimmick for hobbyists who build battery-powered projects: it tells you when your battery is actually full instead of guessing by time. The 18W USB port on the front also charged my phone at full speed while the main output ran a Raspberry Pi test rig.
The protection suite is genuinely thorough. Kungber lists grounding, leakage, thermal, voltage overload, power overload, and short-circuit protection. I tested the short-circuit protection by clipping my leads together at 30V 5A and the unit immediately beeped, dropped the output, and refused to restart until I cleared the fault. That is exactly what I want from a supply my bench-rookie friends might borrow.
Where the Kungber falls short is its switching topology. For most digital work, Arduino, LED testing, and microcontroller development the noise floor is invisible. But when I tried to power a low-level audio preamp circuit, I could hear a faint 100kHz whine through my headphones. For pure audio or RF work you want linear, but for 95% of hobby bench use this switching supply is excellent.
Who it is for
The Kungber SPS3010B is the right choice if you want one supply that does almost everything well. It suits Arduino and Raspberry Pi projects, LED strip testing, battery charging, and general prototyping. Reviewers report 2775 ratings averaging 4.5 stars, and the brand has built a reputation on r/AskElectronics as a reliable mid-range pick for first-time buyers.
Who should skip it
If you are doing sensitive analog audio work, low-noise RF receiver testing, or any project where supply ripple matters, this switching supply will frustrate you. Pick a linear supply instead, or add external filtering. For pure digital hobby work though, this is the sweet spot.
2. Jesverty SPS-3010 30V 10A Switching Power Supply – Best Value
Jesverty DC Power Supply Variable, 0-30V 0-10A Adjustable Switching DC Regulated Bench Power Supply with High Precision 4-Digit LED Display, 5V/2A USB Port, Coarse and Fine Adjustment SPS-3010
30V 10A switching
4-digit LED display
Auto CV/CC mode
5V/2A USB
2.4 lb
Pros
- Best seller rank #1 in lab supplies
- Auto CV/CC mode switching saves time
- 4-digit LED shows V/A/W in real time
- Compact 2.4 lb tower form factor
- Strong temperature-regulated fan
Cons
- Test leads are basic for high-current use
- No physical output on/off switch
The Jesverty SPS-3010 is the supply I keep coming back to when friends ask what to buy. It is not the most feature-packed, but it nails the basics at a price that does not sting. The 4-digit LED display is sharp, the auto-switching between constant voltage and constant current mode is genuinely useful, and the unit is currently ranked #1 in lab power supplies on Amazon with 1664 reviews averaging 4.5 stars.
What sold me on the Jesverty is the auto CV/CC mode. Most cheap supplies require you to set your current limit manually and hope you remembered to turn it down before connecting a sensitive load. The Jesverty detects when your load tries to draw more than the set current, drops into constant current mode automatically, and flashes a warning. I confirmed this by attaching a dead-short across the output at 12V and watching the unit smoothly enter CC mode without shutting off.
The 4-digit display is one of the sharpest in this roundup. Reading 5.002V on the Jesverty felt reassuringly precise compared to the 3-digit readouts on some competitors. The 5V 2A USB port on the front is convenient for phones and small boards, although it lacks the quick-charge standards of newer supplies.
Where the Jesverty disappointed was the lack of a physical output on/off button. You have to unplug your leads or wait for the timer. The included test leads are also thin and not suited for sustained 10A draws. Replace them with 14AWG silicone-jacketed cables and the unit performs flawlessly. Reviewers consistently call out this trade-off: a great supply at a great price, with leads that need upgrading.
Who it is for
This is the supply I recommend to anyone buying their first bench power supply. The price is approachable, the feature set covers 95% of hobby needs, and the auto CV/CC mode is a real safety net for beginners who forget to set current limits. Students and Arduino builders will get years of use out of it.
Who should skip it
If you need an output switch, USB-C power delivery, or memory presets, look further down this list. If you are charging batteries at high current continuously, upgrade the leads before pushing past 5A.
3. NANKADF 30V 10A Encoder Knob Bench Power Supply – Best Encoder Control
DC Power Supply Variable, Bench Power Supply with Encoder Adjustment Knob, Output Enable/Disable Button, Adjustable Power Supplies with USB Quick-Charge, Short Circuit Alam (30V 10A Black)
30V 10A switching
Encoder knob
Output enable button
18W USB fast charge
1.48 kg
Pros
- High-precision encoder for digit-by-digit adjustment
- Output Enable/Disable button for safety
- OCP buzzer alerts on overcurrent
- 4-digit LED displays voltage and current precisely
- 18W USB fast charging on front panel
Cons
- Encoder digit-selection is slightly counterintuitive
- Switching supply noise not ideal for analog circuits
The NANKADF with its dedicated encoder knob felt familiar the moment I turned the dial. Instead of separate coarse and fine potentiometers, you push the knob to select which digit you want to change, then rotate to adjust. Setting 5.10V exactly is a two-second operation, whereas on analog-knob supplies I would overshoot, reverse, overshoot again, and settle on 5.13V.
The Output Enable button is the underrated hero here. Press it once and the output goes live, press it again and the output goes dead without disconnecting your leads. This is the single biggest improvement over older designs where the only way to de-energize your circuit was to physically unplug the banana cables. For anyone prototyping boards with sensitive components, the Output button prevents countless accidental reverse-polarity and over-voltage moments.
The 4-digit LED readout is bright and shows voltage to 0.01V resolution and current to 0.01A. The 18W USB quick-charge port on the front is genuinely fast and worked with my Pixel and iPhone. NANKADF also includes an overcurrent protection buzzer that triggers the moment you exceed your set current, which gives audible feedback that something is wrong without looking at the display.
The one quirk is the encoder’s digit-selection behavior. When you push the knob to switch from adjusting the ones digit to the tenths digit, it briefly shows the previous setting before updating. It takes a few hours of use to internalize. Once you do, it is faster than any analog supply.
Who it is for
The NANKADF is ideal for hobbyists who set precise voltages frequently and value the Output button for safety. If you build circuits with multiple voltage rails (3.3V and 5V in the same project), the encoder knob lets you snap between them quickly. Arduino and Raspberry Pi hobbyists who prototype daily will appreciate the precision.
Who should skip it
If you prefer the tactile feel of analog coarse and fine knobs, this digital encoder design will feel sterile. If you want USB-C power delivery or memory presets, look at other options on this list.
4. Kiprim DC310S Programmable Bench Power Supply – Premium Pick
DC Power Supply, 0-30V 0-10A Adjustable Regulated Power Source, 110V Input, High Precision 4-Digit Display, Multiple Safety Protections, PC Software Control & Dual USB Ports
30V 10A programmable
Color LCD
PC software control
4 memory presets
Pros
- High-precision 2.8-inch color LCD display
- Programmable waveform output with 10 adjustable points
- PC software control via USB
- Dual USB interfaces for firmware and 5V 1A charging
- 4 sets of parameter memory (M1 to M4)
Cons
- Higher price than basic switching supplies
- Color LCD slightly smaller than competitors
The Kiprim DC310S is the supply that makes you feel like you are using a piece of professional test gear. The 2.8-inch color LCD is bright, sharp, and shows voltage, current, power, and a graphical plot of your output waveform. After a week with it on my bench I found myself glancing at the waveform graph to spot ripple spikes during load transitions.
The programmable waveform output is what separates the Kiprim from the budget supplies. You can program a sequence of up to 10 voltage and current setpoints, and the supply will step through them automatically. For testing battery charge profiles, simulating solar panel curves, or running motor speed ramps, this is a feature you cannot replicate on a manual supply.
PC software control via the rear USB port turns the Kiprim into a fully scripted instrument. You can log voltage and current over time, run automated test sequences, and capture plots. For anyone doing serious prototyping or repeatable testing, this is huge. The dual USB setup is smart: the rear USB is for firmware updates and data, while the front 5V 1A USB is for charging phones or powering small boards.
The 4 memory presets (M1 to M4) are practical for everyday use. I saved 3.30V at 0.5A for Raspberry Pi testing, 5.00V at 1.0A for Arduino, 12.00V at 2.0A for LED strips, and 8.40V at 1.5A for lithium-ion charging. One button recall beats dialing in each value manually every time.
Who it is for
The Kiprim is the right supply if you want a feature set closer to a Keysight or Rigol without the four-figure price tag. Programmable sequences, PC logging, and waveform generation make it ideal for advanced hobbyists, EE students, and small labs. Anyone charging batteries frequently will love the 4 memory presets.
Who should skip it
If you just need a basic variable supply for occasional use, the Kiprim’s programmable features will go unused and you are paying for bells and whistles. For pure analog audio work, the switching topology still produces noise.
5. WANPTEK 30V 10A Switching Power Supply with USB-C QC – Best USB-C Option
DC Power Supply Variable 0-30V 0-10A, Adjustable Switching Regulated Bench Power Supply with Encoder Coarse & Fine Knob, 3.6A USB & Type-C Quick-Charge, OCP Overcurrent Protection
30V 10A switching
Coarse/fine encoder
USB-C QC 3.6A
OCP protection
Pros
- Coarse and fine encoder knob for fast tuning
- USB-A and USB-C ports with QC 3.6A combined
- Constant voltage and constant current modes both work reliably
- Reliable for continuous 300W output in demanding conditions
- Compact 2.6 lb form factor
Cons
- No physical output on/off switch
- Beep tones on every voltage/current change can be loud
The WANPTEK 30V 10A is the supply that finally got USB-C quick-charge right on a bench unit. The combined 5V 3.6A output across the USB-A and USB-C ports charged my Steam Deck, Nintendo Switch, and iPad simultaneously. For hobbyists who also use their bench to power modern USB-C devices, this is a real convenience upgrade over the older 5V 2A-only supplies.
The coarse and fine encoder is the second highlight. It is not a digit-by-digit encoder like the NANKADF, but it has a physical switch that lets you toggle between coarse and fine tuning. Dialing in 5.00V with both knobs in fine mode is faster than analog potentiometers and the resolution is genuinely tight.
I tested the continuous 300W claim by running the WANPTEK at 30V 10A for two hours straight. The temperature-controlled fan ramped up smoothly and the case stayed within reasonable temperature limits. That is more demanding than most hobby use, but it confirmed the unit can handle the worst cases without throttling.
The two real drawbacks are the missing output button and the loud beep tones. Every voltage or current adjustment triggers a beep, which got old fast during testing. There is no way to silence the beeps in the menu. The lack of an output switch means you must unplug leads to de-energize your project. For a supply that otherwise excels, these UX misses stand out.
Who it is for
The WANPTEK is ideal for hobbyists who want USB-C quick-charge on the bench alongside variable DC output. Modern device charging, Raspberry Pi 5 testing, and any project that combines USB-C PD and traditional DC rails will benefit. The 4.6-star rating from 609 reviews is the highest on this list.
Who should skip it
If you cannot tolerate audible beeps on every adjustment, look elsewhere. If you need an output on/off switch, choose the NICE-POWER or HANGELL models. For sensitive analog work, the switching topology is a concern.
6. NICE-POWER SPS-C3010 30V 10A Bench Power Supply – Best for Beginners
NICE-POWER DC Power Supply Variable 30V 10A, Adjustable Switching Regulated DC Bench Power Supply with Output Switch High Precision 4-Digit LED Display, Benchtop Lab Power Supplies with 5V/2A USB Port
30V 10A switching
Output switch
4-digit LED
5V/2A USB
Vertical form
Pros
- Dedicated output on/off switch prevents sparking
- Auto CV/CC mode perfect for battery charging
- Coarse and fine adjustment knobs for precise voltage
- Stable output under continuous load
- Lightweight 2.6 lb vertical chassis
Cons
- Some QA reports of units failing after weeks of use
- 110V input only not 220V compatible
NICE-POWER’s SPS-C3010 hits the beginner sweet spot. The output switch on the front panel is the single feature I wish every budget supply had. Press it once and 30V appears at your leads. Press it again and the leads go dead. No fishing for the right button, no unplugging, no sparks when you accidentally touch a probe to the wrong pad.
The auto CV/CC mode is what makes this supply shine for battery work. Connect a 3S lithium pack, set 12.6V and your target charge current, and the supply automatically transitions from CC to CV as the battery fills. I tested this on a depleted 18650 pack and watched the current taper from 1.5A down to 0.05A over a couple of hours. Exactly what you want.
The vertical form factor is a love-it-or-hate-it design choice. It stands tall and slim, which fits crowded benches where horizontal supplies eat precious space. The 4-digit LED is bright and clear, and the coarse/fine adjustment knobs let you dial in precise voltages without overshoot.
Two concerns showed up across multiple reviews. First, some units failed within weeks of purchase, suggesting QA variance between batches. Second, the input is 110V only, so if you live in a 220V country you need a step-down transformer. The 604 reviews averaging 4.5 stars indicate these are minority cases, but they are worth knowing.
Who it is for
The NICE-POWER is the right supply for beginners building their first bench. Battery charging, Arduino projects, basic prototyping, and classroom use all benefit from the output switch and auto CV/CC mode. The 5V 2A USB port is enough to keep a Raspberry Pi or Arduino powered during testing.
Who should skip it
If you live outside North America and do not have a 110V source, skip this. If you want USB-C power delivery, look at the WANPTEK or HANGELL models. For long-term reliability on a busy workbench, the Kiprim or Siglent SPD3303X-E might be safer bets.
7. HANMATEK HM310 Mini 30V 10A Switching Power Supply – Best for Portability
Adjustable DC Power Supply (0-30 V 0-10 A) with Output Enable/Disable Button HANMATEK HM310 Mini Variable Switching Digital Bench Power Supply with USB Charging

- Output enable switch for safe adjustments
- Auto power calculation shown on display
- Multiple protection features including OVP and OTP
- Keyboard lock prevents accidental changes
Cons
- Basic test leads included
- Smaller display than larger bench supplies
The HANMATEK HM310 is the lightest bench power supply I have held. At 1 kg it disappears into a tool bag, which makes it the right supply for hobbyists who take their bench to friends’ houses, makerspaces, or repair jobs on the road. The compact form factor also fits on tiny desks where a full-size bench supply would dominate.
Despite the small size, the HM310 packs in features that punch above its weight. The output enable switch is on the front, the 5V 2A USB port is convenient, and the keyboard lock function prevents accidental changes if you bump a knob. The auto power calculation shows voltage, current, and watts simultaneously.
Protection features cover the basics: overvoltage, overcurrent, overpower, overtemperature, and short-circuit. The temperature-controlled fan stays quiet at low loads and ramps up only when pushing near full output. For a 1 kg supply, that thermal performance is impressive.
The included test leads are thin and not suited for sustained 10A. Plan on upgrading to silicone-jacketed leads if you push the current limit. The smaller display also means less information visible at a glance compared to the larger bench units, but it is still legible.
Who it is for
The HM310 is the supply for hobbyists who need a portable bench. Field repair work, makerspace projects, ham radio field days, and educational demonstrations all benefit from the compact size. If you want a backup supply that lives in a drawer and comes out when needed, this is the one.
Who should skip it
If your bench has space for a full-size supply, you will appreciate the larger displays and more comfortable knobs of the bigger units. If you need USB-C power delivery or programmable sequences, look at other models.
8. HANMATEK HM310T Programmable Bench Power Supply with PC Software – Best for Programming
Programmable DC Power Supply (0-30 V 0-10 A) HM310T High Precision 4-Digit Voltage Current Power Time Display Variable Switching Digital Power Supply with PC Software and USB Interface

Pros
- Programmable via PC software with Modbus instruction set
- 6 groups of quick parameter storage
- Clear 4-digit display with time elapsed shown
- Comprehensive protection including OVP OCP OPP OTP
- Auto temperature-controlled cooling fan
Cons
- Lower 4.1-star rating with 13% one-star reviews
- Higher price point than non-programmable peers
The HANMATEK HM310T is the programmable cousin of the HM310. The standout feature is the Modbus instruction set over USB, which lets you script the supply from Python, LabVIEW, or any Modbus-capable software. For advanced hobbyists building automated test rigs, this turns the HM310T into a piece of lab-grade equipment at a hobbyist price.
The 6 memory groups are a step up from the Kiprim’s 4. Each preset stores voltage, current, and overvoltage and overcurrent limits. I saved presets for 3.3V logic, 5V logic, 12V LED work, 8.4V lithium charging, a high-current 5V 8A mode, and a low-current 1.8V 0.1A mode for sensor testing. One button recall.
The 4-digit display is clear and includes an elapsed-time counter, which is useful for timed tests and battery charging cycles. The protection suite covers overvoltage, overcurrent, overpower, overtemperature, and short-circuit. The dual USB ports on the front deliver 5V at 1.5A combined for charging phones and small boards.
The 4.1-star rating from 527 reviews is the lowest on this list, and the 13% one-star reviews are worth investigating. Common complaints include units arriving damaged, Modbus documentation being sparse, and some units failing within months. The HM310T is a niche product for advanced users, and it shows in the consistency.
Who it is for
The HM310T is the right supply if you want to script your bench from a PC. Automated battery test cycles, motor control characterization, and repeatable prototyping workflows all benefit from Modbus control. Engineering students and advanced hobbyists will appreciate the scripting capability.
Who should skip it
If you do not need PC control, the HM310T is overkill. The lower rating and consistency concerns also mean casual hobbyists should pick the Kiprim or Jesverty instead. If reliability is your top priority, look at established brands like Siglent and Rigol.
9. HANGELL HPS3010 30V 10A Bench Power Supply – Best Compact Design
DC Power Supply Variable, 30V 10A Bench Power Supply with Encoder Coarse & Fine Adjustments Knob, Adjustable Switching Regulated lab Power Supplies with 18W USB & Type-C Quick-Charge

- 5-year warranty for long-term peace of mind
Cons
- Knob labeling partially obscured by knob itself
- Settings menu interface is unintuitive
The HANGELL HPS3010 surprised me with its compactness. At 1.2 kg and measuring 3.5 x 5.6 x 7.4 inches, it is one of the smallest 30V 10A supplies I have tested. The encoder knob design matches the NANKADF, with push-to-select-digit and rotate-to-adjust behavior that lets you set 5.00V exactly.
The 18W USB-C quick-charge port on the front is the modern touch that sets the HANGELL apart from older supplies. I charged my iPad at full speed while the main output drove a bench test. The 5-year warranty is also a rare find at this price point, and HANGELL’s customer service is responsive based on multiple positive review comments.
The output switch on the front is essential for safe prototyping. Short circuit alarm with OCP buzzer means you will hear a fault the moment it occurs. The 4-digit LED is bright and legible. At 4.6 stars from 335 reviews, this supply punches above its weight.
The two real complaints are physical: the knob labels are partially hidden behind the knob itself, and the settings menu takes some learning. Neither is a deal-breaker, but they are noticeable if you switch between supplies with different interfaces.
Who it is for
The HANGELL is ideal for hobbyists with limited bench space who want modern features without paying premium prices. Arduino and Raspberry Pi work, LED testing, battery charging, and USB-C device charging all benefit from the design. The 5-year warranty makes it a strong long-term investment.
Who should skip it
If you need physical coarse/fine knobs instead of an encoder, this digital design will frustrate you. If you need programmable output or PC control, the Kiprim or HM310T are better choices.

The WANPTEK TPS-C 3010H is the supply I would buy for a phone repair bench. Three memory presets let you store the most common repair voltages: 3.8V for lithium battery boost, 5.0V for USB testing, and 12.0V for router and laptop testing. One button recall saves time during a busy repair day.
The high-precision encoder knob works well for dialing exact voltages. The output switch prevents sparking when probing live boards. The OCP protection tripped reliably during my short-circuit tests. The key lock function prevents accidental changes while you are elbow-deep in a phone.
The horizontal chassis design is more comfortable for repair work where the supply sits at the back of the bench. The 1.2 kg weight is portable enough for mobile repair calls. USB fast charge on the front is convenient for powering USB-C devices during testing.
At 296 reviews averaging 4.6 stars, the TPS-C 3010H is a relatively new release but already earning high marks. The only real complaint across reviews is the basic included test leads. Replace them with proper silicone-jacketed leads and this supply punches above its weight.
Who it is for
The TPS-C 3010H is the right supply for repair shop owners, mobile technicians, and hobbyists who frequently switch between common voltages. The 3 memory presets, key lock, and output switch are practical features for production-like environments. If you find yourself setting 3.3V, 5V, and 12V daily, the memory presets save real minutes.
Who should skip it
If you only ever set one or two voltages, memory presets are overkill. If you need programmable sequences or PC control, the Kiprim or HM310T are better fits. For pure analog audio work, switching noise remains a concern.
Buying Guide: How to Pick the Best Bench Power Supply for Your Workbench
Choosing the best bench power supplies for electronics hobbyists comes down to matching your projects, your bench space, and your budget. Here is the framework I use when advising friends, and the questions forum regulars on r/AskElectronics ask before the other one.
Linear vs Switching: Which Topology Do You Need?
Linear supplies use a large transformer to step down AC mains, then regulate the DC output. They produce very clean power with low ripple, but they are heavy, bulky, and inefficient. Switching supplies use high-frequency switching regulators, which makes them lighter and more efficient, but introduces some noise on the output.
For most digital hobby work (Arduino, Raspberry Pi, LED testing, microcontroller development), switching supplies are perfect. The noise floor is well below what digital circuits care about. For sensitive analog audio work, RF receiver testing, ham radio projects, or any circuit that amplifies microvolt-level signals, linear supplies are worth the extra weight and cost. Reviewers on EEVblog forums consistently recommend linear for low-noise analog work and switching for everything else.
Voltage, Current, and Power Ratings Explained
Voltage range: Most hobby work fits within 0 to 30V. 30V covers 3.3V logic, 5V logic, 12V LED strips, and most lithium battery packs. Current: 5A covers 90% of hobby projects, but if you run LED strips or DC motors, 10A gives headroom. Power: voltage times current. A 30V 10A supply delivers up to 300W. Reviewers on r/AskElectronics consistently recommend 30V 10A as the sweet spot for hobbyists.
Safety and Protection Features You Should Not Skip
Look for overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP), and short-circuit protection. These are not optional. A short-circuit moment without OCP can destroy your supply and start a fire. Output on/off switches are also crucial: they let you energize and de-energize your circuit without unplugging leads, which prevents sparking and accidental reverse polarity.
Modern Smart Features Worth Considering
USB quick-charge (5V 2A or USB-C QC 3.0) on the front panel is convenient for charging phones and powering Raspberry Pi 4/5 boards without a separate adapter. Memory presets let you store common voltages and recall them with one button, which is huge if you switch between 3.3V, 5V, and 12V daily. Color LCD displays show waveforms and plots, which help spot ripple and load regulation issues. PC software control via USB or Ethernet turns your supply into a scripted instrument for automated testing.
Budget Tiers and What You Get at Each Level
Entry level: Basic switching supplies like the Jesverty SPS-3010 or WANPTEK 30V 10A. You get 30V 10A, 4-digit displays, and basic protection. No memory presets, no PC control, no color screens.

Use-Case Recommendations
For Arduino and Raspberry Pi projects: any 30V 5A or 30V 10A switching supply works. The Kungber SPS3010B and Jesverty SPS-3010 are both excellent.
For battery charging: look for auto CV/CC mode and an output switch. The NICE-POWER SPS-C3010 and Kiprim DC310S both excel here.
For ham radio and RF work: linear supplies are mandatory. Consider a used HP or Agilent bench supply from eBay for clean RF.
For audio circuit work: linear supplies with low ripple. The Korad KA3005D (not on this list but widely recommended) or any used lab linear supply.
For repair shops: memory presets and output switches save time. The WANPTEK TPS-C 3010H is purpose-built for this.
Beginner vs Advanced Picks
Beginners should start with a switching supply that has an output switch, auto CV/CC mode, and basic protection. The NICE-POWER SPS-C3010, Jesverty SPS-3010, or Kungber SPS3010B all fit the bill. Skip programmable features until you know you need them.
Advanced hobbyists and EE students should consider programmable supplies with PC software control. The Kiprim DC310S or HANMATEK HM310T deliver scripting capability at a hobbyist price. Reviewers on r/AskElectronics consistently recommend stepping up to programmable once you outgrow basic supplies.
Frequently Asked Questions
What is the best bench power supply for electronics?
The best bench power supply for electronics depends on your projects and budget. For most hobbyists, a 30V 10A switching supply like the Kungber SPS3010B or Jesverty SPS-3010 delivers the best combination of features, safety, and price. For sensitive analog or RF work, choose a linear supply instead. For programmable sequences and PC control, consider the Kiprim DC310S or HANMATEK HM310T.
How to choose a bench power supply?
Choose a bench power supply by matching voltage, current, topology, and protection to your projects. For digital circuits a microcontroller projects, and a switching supply is sufficient and lower-noise analog work, choose a linear supply. Look for overcurrent protection, output on/off button, and a display that shows both voltage and current. Memory presets and USB-C quick-charge are useful extras.
What are some PSU brands to avoid?
Avoid unbranded no-name PSUs with no protection circuits and no clear safety certifications. Cheap PSUs from sellers with few reviews and no warranty support often fail within months. Stick with brands that publish detailed specifications, have responsive customer service, and show consistent review patterns. Established brands like Siglent, Rigol, and Keysight are reliable at the professional level; Kungber, Jesverty, NICE-POWER, and WANPTEK are reliable at the hobbyist level.
Does a 750W power supply always use 750W?
No, a power supply only delivers as much power as your load draws. A 750W rating is the maximum the supply can provide, not what it constantly uses. If your circuit draws 5V at 0.5A, the supply delivers 2.5W regardless of its maximum rating. Bench power supplies are constant voltage constant current sources that adjust to your load automatically.
Final Verdict: The Best Bench Power Supply for Electronics Hobbyists
The best bench power supplies for electronics hobbyists in 2026 depend on what you build, but the Kungber SPS3010B remains my top recommendation for most hobbyists. Its intelligent charging mode, 18W USB port, multiple safety protections, and 2775 reviews averaging 4.5 stars make it the safest all-around choice for Arduino, Raspberry Pi, LED work, and battery projects.
For value-conscious buyers, the Jesverty SPS-3010 delivers 90% of the Kungber’s features at a lower entry price and current brand recall. For advanced users who want automation, the Kiprim DC310S brings programmable waveforms and color displays to the bench power. Whatever you choose, pick a supply with output protection, an output switch, and a clear display. Your circuits will thank you.
