I’ve spent the last three months testing eight benchtop power supplies on my electronics bench, running everything from Arduino prototypes to LED strip arrays and motor driver boards. My workbench saw more than 200 hours of real project time across these units, and the difference between a quality supply and a cheap one shows up fast when you’re debugging a sensitive circuit.
A benchtop power supply is a variable DC source that sits on your workbench and lets you dial in exact voltage and current for testing electronics. Instead of guessing with wall adapters or batteries, you get precise control, real-time readouts, and built-in protection against short circuits and overloads. If you’re a hobbyist, student, or maker working with Arduino, Raspberry Pi, audio circuits, or motor controllers, a good bench supply pays for itself the first time it saves a component from burning up.
After weeks of hands-on testing for 2026, I narrowed the field to eight standout units spanning budget, mid-range, and professional tiers. This guide covers what each one does best, where it falls short, and how to pick the right one for your projects and budget.

1. Jesverty SPS-3010 – Budget-Friendly Powerhouse for Beginners
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 output
4-digit LED display
2.5lbs compact
5V/2A USB port
Pros
- 4-digit V/A/W display shows real-time power draw
- Auto CV/CC mode switching protects circuits
- Lightweight 2.5lb tower fits small benches
- Multiple protection features included
- USB port charges phones and Raspberry Pi
Cons
- Test leads included are basic quality
- Power cord varies by destination
The Jesverty SPS-3010 was the first unit I pulled out of the box, and for the price, it punched well above its weight. I used it for a two-week Arduino prototyping marathon, powering everything from 5V sensor arrays to 24V LED strips, and the 4-digit LED display never let me guess what was happening on the output. I could see exactly when my circuit drew too much current and the supply gracefully switched into constant current mode.
What surprised me most was the compact form factor. At 2.5 pounds and roughly the size of a thick paperback, it tucks into a corner of my bench without dominating space. The 5V/2A USB port on the front became a daily convenience for charging my phone and powering a Raspberry Pi 4 during headless setup sessions. The constant voltage to constant current auto-switching saved me at least three times when I accidentally shorted a prototype board.
During testing, I pushed 9 amps through a motor driver circuit for sustained periods and the temperature-controlled fan ramped up smoothly without becoming obnoxious. The included test leads are functional but flimsy – I swapped mine for banana-to-alligator leads within a day for better grip on component leads. The coarse and fine adjustment knobs let me dial in 3.300V with confidence, which matters when you’re testing voltage regulators.
The protection suite covers short-circuit, over-load, grounding, and over-temperature scenarios. I deliberately triggered the short-circuit protection by bridging the output with a screwdriver, and the unit shut down in under a second with a clear error on the display. For beginners stepping up from USB power or batteries, this Jesverty delivers genuine lab-grade functionality without the lab-grade price tag.
Best use cases for this unit
Arduino and Raspberry Pi hobbyists who need reliable 5V and 3.3V rails will find the Jesverty SPS-3010 covers 90% of typical maker projects. Students in electronics labs benefit from the clear readouts and safety features that prevent component damage. Anyone running LED projects at 12V or 24V gets clean power with consistent current limiting, making it ideal for brightness testing.
Where this unit struggles
The basic test leads are the biggest weakness – you’ll want to budget for quality banana leads separately. Audio purists working on low-noise amplifier circuits may notice more switching noise compared to linear supplies. Power users needing more than 10 amps or precise remote programming should look at higher-tier models.
2. NICE-POWER SPS-C3010 – Feature-Packed Mid-Range Workhorse
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 300W
Output switch
4-digit display
5V/2A USB
Pros
- Output switch enables safe on/off without unplugging
- 8 protection functions cover every fault scenario
- 4-digit display with 0.01V/0.001A resolution
- Intelligent temperature-controlled fan
- 5V/2A USB charging port
Cons
- Only 110V input for US standard
- No 220V input available
The NICE-POWER SPS-C3010 earned a permanent spot on my bench during testing because of one feature I now consider essential: the OUTPUT switch. Being able to cut power to my circuit without unplugging leads saved countless hours of wear on my test leads and connectors. I found myself reaching for it whenever I needed to swap components or reset a microcontroller.
The 8 protection functions are comprehensive – leakage, grounding, over-voltage, over-current, over-power, over-load, over-temperature, and short-circuit. During testing, I deliberately overloaded the output to trigger OCP, and the unit shut down cleanly with no drama. The 4-digit LED display with 0.01V and 0.001A resolution gave me confidence that what I dialed in was actually what I got at the terminals.
The intelligent fan stayed nearly silent at low loads and ramped up smoothly during a 7-amp sustained draw test. The coarse and fine adjustment knobs operate independently, which I prefer over combined controls for precision work. At 2.6 pounds, it’s slightly heavier than the Jesverty SPS-3010 but still very portable for field work or repair calls.
One thing to note: this unit is 110V input only for US buyers. International users will need a step-down transformer or should consider the Jesverty SPS-3010V instead, which has selectable AC input. The USB port delivered consistent 5V/2A output even when the main terminals were under heavy load, which I confirmed by charging a tablet while running a 5A circuit.
Best use cases for this unit
Electronics repair technicians who need to swap components quickly benefit enormously from the output switch. Educators running classroom labs appreciate the comprehensive safety protections and clear displays. Anyone building battery-powered projects at 12V or 24V gets reliable power with accurate current limiting for capacity testing.
Where this unit struggles
The 110V-only input is the main limitation for users outside North America. There’s no computer interface for automated testing or logging, so data-driven users will want to step up to a programmable model. The vertical form factor, while space-efficient, can be awkward if you prefer horizontal stacking on a crowded bench.
3. Jesverty SPS-3010V – The Encoder Upgrade I Recommend Most
Jesverty DC Power Supply Variable, 0-32V 0-10A Switching Bench Power Supply with 20W USB & Type-C Quick-Charge, Encoder Corase & Fine Adjustment Knob, Output Switch, 4-Digit LED Display – SPS-3010V
32V 10A 320W
Encoder control
USB-C 20W
Selectable AC input
Pros
- Encoder coarse and fine knobs for precise adjustment
- 20W USB-A and USB-C quick-charge ports
- AC115V/230V selectable input
- Output ON/OFF button for safe operation
- CE/FCC/OCP certified
- Compact 2.5lb design
Cons
- Power cords vary by destination
- Basic test leads included
The Jesverty SPS-3010V is the unit I kept coming back to throughout testing, and it’s my top pick for most hobbyists in 2026. The encoder knob with separate coarse and fine adjustment felt like a major upgrade over standard potentiometers. I could rapidly scroll from 0V to 30V and then dial in the last 0.05V with a single click of the encoder, which made voltage regulator testing dramatically faster.
The 20W USB-C quick-charge port transformed how I work. Instead of reaching for a separate charger, I powered my USB-C soldering iron, charged my phone, and ran a Raspberry Pi 4 from the same supply simultaneously. The dual USB-A and USB-C ports support modern fast-charge protocols, which means you can fast-charge a phone while the main output drives a project circuit.
What sealed the deal for me was the AC115V/230V selectable input. International users no longer need a bulky step-down transformer, and travelers can switch inputs with a rear-panel toggle. The 32V maximum voltage (versus 30V on most competitors) gives extra headroom for testing 24V systems with margin to spare. The CE, FCC, and OCP certifications mean this unit passes safety inspections in commercial and educational settings.
During my motor driver testing, I pushed the SPS-3010V to 9.5 amps sustained for 20 minutes while the output switch let me cycle power without touching the leads. The fan ramped up appropriately but never became intrusive. The temperature sensor engaged the protection circuit at the right threshold during my deliberate thermal stress test, shutting down cleanly before any damage occurred.
Best use cases for this unit
Makers working across multiple projects simultaneously benefit from the fast-charge USB ports combined with variable DC output. International hobbyists and students who travel get flexibility from selectable AC input. Engineers testing 24V industrial sensors or motor controllers get extra voltage headroom at 32V maximum. Anyone wanting precise voltage control will appreciate the encoder adjustment over analog knobs.
Where this unit struggles
Power users running three or more devices may exhaust the 10A current budget quickly. There’s no remote computer control for automated test sequences, so users running data acquisition should consider the FNIRSI programmable models instead. The encoder knob has a slight learning curve compared to traditional knobs, though most users adapt within a day.
4. NICE-POWER SPS-E3010 – Ultra-Compact Power for Tight Spaces
NICE-POWER DC Power Supply Variable 0~30V 0~10A, 3-Digits LED Display Current and Voltage Adjustable 150W Fixed with Encoder DC Bench Power Supply 15V 10A/30V 5A,Electroplating DIY etc PSU
150W fixed
15V/10A or 30V/5A
Ultra compact
3-digit display
Pros
- Ultra-compact size under 1kg
- Switchable 15V 10A or 30V 5A modes
- Encoder button for precise adjustment
- Wide input voltage 100V-240V
- Good value for price
Cons
- EMI noise under heavy load
- Small ripple at output around 100mV
- Limited to 150W total power
The NICE-POWER SPS-E3010 is the smallest benchtop power supply I tested, weighing under 1 kilogram and measuring roughly the size of a hardcover book. I tossed it in my laptop bag for a week of on-site repair work and barely noticed it. For hobbyists with cramped workspaces or makers attending events and workshops, this size advantage is significant.
The switchable 15V/10A or 30V/5A mode is an interesting design choice. Instead of one continuous range, you get two optimized presets that match common project voltages. The 15V/10A mode is ideal for battery charging projects, while the 30V/5A mode covers most Arduino and microcontroller work. I found this limitation acceptable for my typical projects but worth noting if you need specific intermediate voltages at high current.
The encoder button for adjustment takes some getting used to – you click to change digits and rotate to adjust. Once I learned the rhythm, I could dial in voltage quickly. The wide 100V-240V input range means international users can plug this in anywhere without configuration. The 3-digit display shows voltage and current but lacks the decimal precision of 4-digit models.
During testing, I noticed some EMI noise when running motor circuits at high current, and the output ripple measured around 100mV under load. These are minor issues for digital projects but could affect sensitive analog audio circuits. The 150W total power limit means you cannot run both maximum voltage and maximum current simultaneously – it’s an either/or design.
Best use cases for this unit
Mobile repair technicians and traveling makers get a genuinely portable bench supply that fits in any bag. Students in dorm rooms with limited desk space benefit from the compact footprint. Anyone running battery charging projects at 12V or 15V gets the high current needed for fast charging. Users who primarily work on digital logic circuits won’t notice the ripple limitations.
Where this unit struggles
Audio engineers and analog circuit designers should skip this model due to the ripple and EMI concerns. Power users needing more than 150W total will hit the limit quickly on demanding projects. The 3-digit display is functional but lacks the resolution needed for precision voltage reference work or calibration tasks.
5. FNIRSI DPS-150 – Premium Compact Design With PC Programming

- 2.8-inch IPS color display with flip feature
- Low ripple under 20mV
- PC programmable with 6 preset groups
- Multiple input modes including PD/QC/DC
- Accurate voltage output
Cons
- Fan can be noisy under heavy load
- Manual lacks detail for advanced features
- Limited to 32V maximum
- No AC input option
The FNIRSI DPS-150 surprised me with its build quality. The aluminum case feels more like a piece of audio gear than a typical bench supply, and the 2.8-inch IPS color display is leagues ahead of the red LED displays on budget models. The display flips 90 degrees, which sounds gimmicky until you mount the unit vertically or look down at it from a standing bench.
The low ripple specification of under 20mV measured accurately in my testing. I hooked it up to a sensitive audio preamp circuit that previously picked up noise from switching supplies, and the DPS-150 stayed quiet. For makers working on radio receivers, audio amplifiers, or precision analog circuits, this low-noise performance justifies the higher price over budget options.
The PC programming capability sets the DPS-150 apart from budget models. Using the FNIRSI software, I set up six preset groups for different project voltages and could switch between them with one click. This is genuinely useful if you repeatedly test the same circuits at different voltages. The software could use better documentation, but YouTube tutorials fill the gap.
The fan became noticeably loud during sustained 4-amp draws in my testing. It’s not unbearable, but if you’re working in a quiet environment or recording audio nearby, plan for some acoustic management. The lack of AC input means you’ll need a separate PD or QC power source, which adds cost if you don’t already have one.
Best use cases for this unit
Audio engineers and analog circuit designers benefit from the low-ripple output that doesn’t contaminate sensitive signals. Engineers running automated test sequences gain value from PC programming and presets. Makers who already own a USB-C PD charger get a clean bench supply without the bulk of traditional units. Anyone wanting a premium feel and display quality at a mid-tier price.
Where this unit struggles
Users without a USB-C PD power source face extra setup costs. The fan noise under load limits use in quiet recording environments. Power users needing more than 5 amps will find the current limit restrictive for motor projects or battery testing.
6. FNIRSI IPS3608 – High-Power Programmable Supply for Demanding Projects

- USB-A and USB-C with multiple fast-charge protocols
- Day and Night UI themes
- PC programmable with real-time curve recording
Cons
- Lower 3.9 rating than competitors
- 12% of reviews are 1-star
- Setup requires PC software for full features
The FNIRSI IPS3608 packs serious power into a compact aluminum chassis, delivering 36V at 8 amps for 285 watts total. I used it to power a 24V brushless motor controller drawing sustained 6 amps, and the supply stayed cool and stable throughout. For projects that demand more current than typical 5A supplies provide, this unit fills an important gap in the market.
The ultra-low ripple under 10mV is among the best I tested. When I powered a precision analog sensor circuit that had been noisy on other supplies, the IPS3608 produced a clean signal that matched my battery reference. The aluminum shell does double duty as a heat sink and EMI shield, which contributes to the clean output.
The Day and Night UI themes on the IPS display are a nice touch for different working environments. The PC software enables real-time curve recording, which I used to log voltage sag during a high-current pulse test on a supercapacitor bank. The 6 preset memory locations covered all my common project voltages without needing to reprogram.
However, the 3.9 average rating with 12% one-star reviews gave me pause. During testing, I experienced one firmware glitch where the unit failed to recognize a saved preset, which I resolved by reflashing via PC. The setup process requires PC software installation to unlock the full feature set, which adds friction for users who want plug-and-play operation.
Best use cases for this unit
Makers working with high-current motor controllers or LED arrays at 24V and above benefit from the 8A capacity. Engineers running battery simulation tests appreciate the PC curve recording feature. Users with multiple USB-C PD devices can consolidate charging and bench power into one unit. Anyone needing low ripple for precision analog work gets clean power at higher current than typical supplies provide.
Where this unit struggles
The reliability concerns reflected in user reviews warrant caution for mission-critical applications. Users wanting simple plug-and-play operation may find the PC software dependency frustrating. The higher price point combined with mixed reviews makes this a calculated choice rather than an obvious upgrade over established models.
7. Rigol DP712 – Professional Lab-Grade Precision

The Rigol DP712 is the most professional-grade unit I tested, and it shows the moment you power it on. The transient response under 50 microseconds is genuinely impressive – when I tested it with a pulsed load, the output recovered faster than any other supply in this roundup. For engineers working on switching power supply design or testing circuits with dynamic loads, this speed matters.
The accuracy specifications are lab-grade: 0.01% plus 2mV load regulation and 0.05% plus 20mV programming accuracy. I verified the voltage output against my calibrated multimeter and the readings matched within the specified tolerance. The 0.2% plus 20mA current readback accuracy is similarly precise, which is essential when you’re characterizing components or validating designs.
RS232 communication enables integration with automated test equipment, and the programmable timing function (10ms to 99999s, up to 2048 steps) covers most production test scenarios. OVP and OCP activate in under 10ms, protecting sensitive devices under test from fault conditions. The Rigol brand reputation for test equipment quality carries over to this supply.
However, the DP712 has some real-world annoyances. The 3.5-inch TFT display, while functional, can dim and reportedly burn out after extended use according to user reports. The interface requires navigating through multiple menus to recall saved settings, which slows down repetitive testing. The unit does not remember last settings at power-up, forcing you to reprogram each time. A popup warning appears every time you exceed 35V, which is a safety feature but becomes tedious during legitimate high-voltage testing.
Best use cases for this unit
Professional engineers and lab technicians who need documented accuracy and fast transient response for characterization work. Production test environments benefit from RS232 integration with automated equipment. Anyone requiring 50V output for testing higher-voltage circuits gets rare capability at this price point. Users who value brand reputation and warranty support for commercial applications.
Where this unit struggles
The limited 3A current output restricts use to lower-power circuits and sensor testing. Hobbyists will find the interface cumbersome compared to modern user-friendly designs. The stock availability concerns and popup warnings during legitimate high-voltage work create friction. The display durability reports warrant consideration for long-term installations.

Three independent isolated outputs mean I can power a 5V microcontroller, a 12V motor, and a 3.3V sensor simultaneously without ground loops or interference between channels. For complex projects requiring multiple voltage rails, nothing else in this roundup comes close.
The series and parallel output modes multiply the flexibility. In series mode, you get up to 64V for testing higher-voltage circuits. In parallel mode, you get 6.4A on a single channel for current-hungry projects. The independent mode lets each output operate as its own isolated supply. I used the timing output function to create a power-on sequence for a mixed-voltage project, and the trending graphs displayed the actual voltage ramps.
The linear power supply design produces exceptionally clean output. When I connected it to my audio test circuit, the SPD3303X-E produced the quietest signal of any supply in this roundup. For analog work, RF projects, or any application sensitive to switching noise, linear regulation makes a measurable difference. The 4.6-star rating across 382 reviews reflects consistent satisfaction in professional and hobbyist communities alike.
The 3-year warranty on the main unit demonstrates Siglent’s confidence in their product. The USB connectivity enables basic logging and remote control without the complexity of RS232. Build quality feels substantial – the unit weighs 17.6 pounds and has a solid tower form factor that stays planted on the bench.
Best use cases for this unit
Engineers and serious hobbyists working on projects with multiple voltage rails benefit enormously from the three isolated outputs. Audio designers and RF engineers get clean linear-regulated power without switching noise concerns. Production test environments gain flexibility from series, parallel, and independent modes. Anyone valuing long-term reliability backed by a 3-year warranty and proven brand reputation.
Where this unit struggles
The 17.6-pound weight and large tower form factor require dedicated bench space. Budget-conscious buyers will find the price hard to justify for simple single-rail projects. The linear design runs warmer than switching supplies, requiring adequate ventilation. Limited Prime shipping options may delay acquisition for some buyers.
Buying Guide: How to Choose the Right Benchtop Power Supply?
Choosing a benchtop power supply comes down to matching your project requirements with the right combination of voltage, current, features, and budget. After testing dozens of units over the years, I’ve learned that overspending on features you won’t use leaves money on the table, while underspending on critical specs creates frustration. Here’s what matters most.
Determine your voltage and current requirements
Start by listing the maximum voltage and current your projects require. Most Arduino and Raspberry Pi projects run on 5V or 3.3V at under 2 amps, so even budget supplies handle them easily. Motor controllers and LED arrays typically need 12V to 24V at 3-10 amps. Industrial sensors and higher-voltage circuits may require 30V or more. I recommend buying a supply that covers your maximum requirement with 20% headroom – this gives you flexibility for future projects without overspending on capacity you’ll never use.
Understand linear versus switching designs
Switching power supplies are lighter, more efficient, and less expensive, but they generate more electrical noise. Linear power supplies produce cleaner output with less ripple but run heavier and hotter. For digital projects, microcontroller work, and most hobbyist applications, switching supplies work perfectly well. For audio circuits, RF projects, and precision analog measurements, linear supplies like the Siglent SPD3303X-E deliver noticeably cleaner results.
Evaluate protection features
Every quality benchtop power supply includes short-circuit protection and current limiting. Better units add over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP), and over-power protection (OPP). These features prevent costly damage when you accidentally short a circuit or push too much current through a sensitive component. The Jesverty and NICE-POWER units I tested include comprehensive protection suites that activate within milliseconds of a fault condition.
Consider display and resolution
A 4-digit LED or IPS display with at least 0.01V and 0.001A resolution helps you dial in precise voltages. 3-digit displays work for general projects but lack the precision needed for voltage regulator testing or calibration tasks. Color IPS displays like those on the FNIRSI models offer better readability and additional information like power calculations and trending graphs.
Connectivity and programming options
USB ports on the front panel add convenience for charging phones and powering Raspberry Pi boards. PC programming capability enables automated test sequences and data logging, which matters for engineers but is unnecessary for most hobbyists. RS232 and Ethernet interfaces serve professional lab environments where integration with automated test equipment is required.
Match your budget to your needs
For beginners and students, the Jesverty SPS-3010 or SPS-3010V delivers genuine lab functionality without breaking the bank. For serious hobbyists working on diverse projects, the Jesverty SPS-3010V offers the best balance of features, build quality, and price. For professional engineers and lab applications, the Siglent SPD3303X-E justifies its premium price with three isolated outputs and linear-clean power.
