3 Group Memory
4-Digit LED
I have been using the HYELEC HY50-06A on my bench for several weeks, and it has become my go-to unit for everyday testing. The 50V maximum output is a real advantage over the standard 30V units — it gives you headroom for projects that need higher rail voltages without forcing you to upgrade later. The 4-digit LED display is crisp and easy to read even under bright workshop lighting, and the readings stay steady without the annoying digit jumping I have seen on cheaper models.
What really sold me is the 3-group memory function. If you regularly charge the same types of batteries or test circuits at specific voltages, being able to save and recall settings with one button press saves a surprising amount of time. I have M1 set for 3.7V lithium battery charging, M2 for 5V Arduino testing, and M3 for 12V automotive sensor work. The output enable/disable button is another feature I did not think I needed until I had it — it lets you dial in your voltage and current settings without accidentally sending power to your circuit.
On the technical side, the HYELEC maintains solid accuracy across its range. I verified output against my Fluke multimeter and saw less than 0.03V deviation at common voltages like 5V, 12V, and 24V. The temperature-controlled fan ramps up smoothly under load and stays quiet during lighter work. The coarse and fine adjustment knobs use a code-type potentiometer system that gives you decent precision, though you will spend a few extra seconds dialing in exact milliamp values. HYELEC claims this unit passed a 72-hour continuous full load test, and based on the build quality, I believe it.
The main tradeoff is the current derating at higher voltages. You get the full 6A up to 25V, but that drops to around 3A when you push toward the 50V maximum. For most hobbyist and prototyping work this is perfectly fine, but if you need both high voltage and high current simultaneously, keep this limitation in mind. Also note this is a 110V-only unit, so it is not suitable for 220V markets without a step-down transformer.
The HYELEC HY50-06A is ideal for electronics hobbyists and intermediate users who want a versatile bench supply that goes beyond the typical 30V limit. If you work with a mix of low-voltage microcontrollers and higher-voltage analog circuits, or if you regularly charge different types of batteries, the memory presets and 50V range make this a standout choice. It is also a great fit for anyone who values having a dedicated output on/off button for safe circuit connections.
If your work consistently demands more than 3A at voltages above 25V, the derating curve may limit you. Users who need ultra-precise milliamp control for sensitive applications might find the potentiometer-based adjustment requires more patience than encoder-based alternatives. And if you live in a 220V region, you will need a separate transformer since this unit only accepts 110V input.

Auto C.V./C.C.
4-Digit LED
The Jesverty SPS-3010 holds the number one spot in the Lab Power Supplies category on Amazon, and after using it extensively, I understand why. This unit delivers the classic 30V/10A spec that covers the vast majority of hobbyist and light professional work, and it does so with remarkable consistency. I ran it through its paces powering Arduino projects, charging lithium battery packs, and driving motors, and it handled everything without breaking a sweat.
The automatic constant voltage and constant current mode switching is one of those features you do not fully appreciate until you use it daily. When you set a voltage limit and a current limit, the supply automatically transitions between C.V. and C.C. modes based on what your load needs. This is especially useful for battery charging, where you want constant current until the battery reaches its target voltage, then constant voltage for the topping phase. The Jesverty handles this transition smoothly, and the 4-digit LED display shows you exactly which mode is active along with real-time voltage, current, and wattage readings.
At just 2.4 pounds, this is one of the lightest bench supplies I have tested, which makes it easy to move around or store when your bench gets crowded. The temperature-regulated fan stays whisper-quiet during low-current work and only ramps up when you are pulling significant power. Build quality is solid for the price — the plastic enclosure feels sturdy, and the banana jack binding posts grip connectors firmly without wobble.
The main issue I noticed is that the coarse adjustment knob covers a wide range very quickly. Small finger movements can jump several volts, which means you need a steady hand when targeting specific values. The fine adjustment knob helps, but its effective range depends on where the coarse knob is positioned. I also recommend upgrading the included test leads for any high-current work — the stock ones are functional but thin, and better leads will give you more accurate readings at the load end.
The Jesverty SPS-3010 is the best bench power supply for most people. If you are a hobbyist, student, or DIY electronics maker who needs a reliable 30V/10A supply for Arduino projects, circuit prototyping, or battery charging, this unit gives you excellent performance without overspending. With over 1400 reviews and a top-category ranking, it has a proven track record that is hard to argue with.
If you need to frequently dial in very specific voltages down to the millivolt, the sensitive coarse knob might frustrate you. Users doing precision analog work or sensitive sensor calibration may prefer a model with encoder-based controls. The included test leads work for basic tasks but should be replaced for anything drawing more than a few amps. This unit also maxes out at 30V, so if your projects require higher rail voltages, look at the HYELEC or the Jesverty SPS-6005 instead.

Charging Mode
18W USB
The Kungber SPS3010B stands out from the crowd with its dedicated intelligent charging mode, and after using it to charge dozens of battery packs, I can say this feature alone makes it worth considering. The charging mode shows you real-time accumulated charge in amp-hours right on the display, which is incredibly useful for monitoring battery capacity and knowing exactly how much energy you have put back into a cell. With 2700+ reviews and a 4.5-star rating, this is one of the most popular bench supplies available, and the user base speaks to its reliability.
The precision encoder knob is a step up from the potentiometer-based controls on most budget units. Instead of a smooth-turning knob that covers a wide range, the encoder gives you positive click feedback and much finer control over your output settings. I found it noticeably easier to hit exact target values like 4.20V for lithium cell charging compared to the Jesverty or NICE-POWER models. The overcurrent protection alarm button is another thoughtful addition — when enabled, it sounds an alert if your load draws more current than expected, which has saved me from a couple of near-mistakes during testing.
The 18W USB port is a nice upgrade over the standard 5V/2A ports on most competitors. It can fast-charge modern phones and tablets, which comes in handy when your phone is your multimeter display or schematic viewer. The compact design weighs in at just 2.3 pounds, making it the lightest unit in our roundup. Kungber backs this supply with a lifetime warranty, which is unusual at this price point and shows real confidence in the product.
There are two quirks worth knowing about. First, the main power switch is on the back of the unit, which means you have to reach around to turn it on and off — not ideal if your bench is tight on space. Second, there is a roughly 10-second delay between turning off the output and the voltage actually dropping to zero at the terminals. This is not a dealbreaker, but it is something to be aware of if you are doing rapid on/off testing. The unit is also CE certified and includes multiple protection layers covering leakage, thermal, over-voltage, over-power, and short-circuit conditions.
The Kungber SPS3010B is the best choice if battery charging is a major part of your workflow. The intelligent charging mode with amp-hour tracking makes it invaluable for anyone who regularly charges lithium-ion, lead-acid, or NiMH battery packs. It is also a strong pick for users who prefer encoder-style controls for precision adjustments. If you work with both electronics and USB-powered devices, the 18W USB port adds genuine convenience.
The rear-mounted power switch can be inconvenient if your bench supply is tucked against a wall or shelf. The 10-second output shutdown delay means this is not the best choice for applications where you need instant output cutoff. And while the encoder knob is great for voltage, some users report it can still be fiddly for setting exact milliamp values in constant current mode. If milliamp precision is critical for your work, you may want to consider a higher-end lab-grade supply.

The NICE-POWER SPS-C3010 proves that you do not need to spend a lot to get a capable bench power supply. At the lowest price point in our roundup, it still delivers the full 30V/10A spec with 300W of output power and a suite of features that punch well above its weight class. I was genuinely surprised by how well this unit performed during testing — the voltage accuracy was within 0.05V of my target across the range, and the C.V./C.C. mode switching worked reliably for both circuit powering and battery charging.
The dedicated OUTPUT switch is a feature I wish every bench supply had, especially at this price. It lets you set your voltage and current with the output disabled, then turn on the output when you are ready. This prevents those moments of panic when you accidentally send the wrong voltage to a sensitive component because you were still adjusting the knob. The coarse and fine adjustment knobs give you reasonable control over your settings, though the potentiometers do not have the click feedback of encoder-based alternatives.
The 4-digit LED display shows voltage, current, and wattage simultaneously, and the resolution down to 0.01V and 0.001A is impressive for this price range. I did notice a slight lag between turning the knob and seeing the display update — it is maybe half a second, but it means you can overshoot your target if you turn too fast. The intelligent temperature-controlled fan stays quiet during light loads and ramps up smoothly when you push higher currents. The rubber feet on the bottom do a good job keeping the unit stable on smooth surfaces.
Protection features are comprehensive for a budget unit. You get over-voltage, over-current, over-power, over-temperature, short-circuit, leakage, and grounding protection. The 5V/2A USB port on the front is handy for powering small USB devices while you work. The vertical form factor takes up less bench space than wider units, which is a real advantage on a crowded workbench. At just 2.6 pounds, it is also portable enough to move between workstations or pack for field work.
The NICE-POWER SPS-C3010 is the best bench power supply for beginners and anyone on a tight budget who still wants genuine 30V/10A capability. If you are just getting started with electronics and setting up your first workbench, this unit gives you all the essential features without requiring a big investment. It is also a smart pick for anyone who needs a second or backup supply for occasional use.
The display lag means you need to make knob adjustments slowly and deliberately to hit exact values. This unit only accepts 110V input, so it will not work in 220V countries without a transformer. The potentiometer-based controls do not have the precision or feel of encoder knobs, which may frustrate users doing fine-tuned analog work. For professional environments or applications requiring lab-grade accuracy, stepping up to a higher-end model would be worthwhile.

C.V./C.C. Auto
4-Digit LED
The Jesverty SPS-6005 fills a specific niche that most bench supplies ignore: it goes all the way up to 60V. Most compact bench supplies top out at 30V, which is fine for general electronics work but falls short for anyone working with 48V telecom equipment, high-voltage LED arrays, or certain battery configurations. I tested this unit specifically with 48V battery charging and high-voltage LED driver testing, and it handled both tasks without issues.
Like its sibling the SPS-3010, the SPS-6005 features automatic C.V. and C.C. mode switching, a 4-digit LED display showing real-time voltage, current, and wattage, and a compact tower design that saves bench space. The temperature-regulated cooling fan operates quietly during low-power use and ramps up appropriately under load. At roughly 3.1 pounds, it is slightly heavier than the SPS-3010 but still very manageable. The 300W total output power gives you plenty of headroom even at the higher voltage range.
The challenge with the SPS-6005 lies in its controls. The coarse and fine adjustment potentiometers are noticeably more sensitive than those on the 30V models, and getting exact voltage values requires a very steady hand. Because the voltage range is twice as wide but the knob rotation is the same, each degree of rotation covers more voltage change. This means tiny movements can shift the output by several hundred millivolts. Users on forums have also reported some quality control variation between units, so buying from a source with a good return policy is wise.
For the right user, though, the 60V capability is a game-changer. If you need to test 48V power-over-ethernet equipment, charge 13S lithium battery packs (54.6V fully charged), or work with industrial sensors that run at 24V-48V, the SPS-6005 saves you from having to buy a much more expensive lab-grade supply. The 1-year warranty from Jesverty provides reasonable coverage, and the USB charging port on the front is a convenient bonus for powering your phone or a small USB device while you work.
The Jesverty SPS-6005 is built for users who regularly work with higher voltages that exceed the 30V limit of standard bench supplies. If you work with 48V telecom equipment, charge high-cell-count lithium battery packs, or test industrial control systems, this is one of the few compact and affordable options that goes to 60V. It is also a good choice for anyone who already owns a 30V supply and needs a complementary unit for higher-voltage tasks.
The sensitive controls mean this unit requires more patience to dial in precise values compared to 30V models with the same knob range. Some users have reported quality inconsistency between units, so testing yours thoroughly upon arrival is important. The 5A current limit is lower than the 10A available on 30V models, so if your high-voltage work also demands high current, you may need to look at professional-grade supplies. The potentiometer knobs lack physical stops, which can make it difficult to find center positions.

Linear Design
Ethernet
The Siglent SPD3303X-E is in a completely different class from the other units in this roundup, and it should be — it is built for professional lab environments where precision, reliability, and versatility are non-negotiable. This is a true linear power supply, which means it delivers exceptionally clean output with minimal ripple and noise. The first time I connected it to an audio circuit and heard absolutely zero power supply hum in the output, I understood why linear supplies matter for sensitive analog work.
Having three independent outputs on a single bench supply is a luxury that changes how you work. Channels 1 and 2 each deliver 32V at up to 3.2A, while Channel 3 provides selectable fixed voltages of 2.5V, 3.3V, or 5V at 3.2A — perfect for digital logic rails. You can run channels 1 and 2 in independent mode for two separate circuits, series mode for up to 64V combined output, or parallel mode for up to 6.4A of current. This flexibility means one unit can handle the work of multiple single-output supplies.
The setting resolution of 1mV and 1mA is professional-grade, and I verified that the output matches the set values with accuracy better than 0.016% across the 1V to 30V range. The timing output function lets you program automated sequences, and while the graphing features are basic, they provide useful visual feedback for monitoring output trends. You can save up to 5 different setups as scenes, which is helpful for recurring tests. The Ethernet and USB interfaces allow remote control from your PC, enabling automated test sequences.
There are tradeoffs with the Siglent that come from its linear design. At 17.6 pounds, this is a heavy unit that stays put on your bench — it is not something you will casually move around. The variable-speed fan is quiet at low loads but becomes audible at higher power levels, which is inherent to linear designs. The third channel lacks a current display and current limiting capability, which limits its usefulness for anything beyond basic logic rail duty. And at its price point, it represents a serious investment that only makes sense if you need its professional capabilities. The 3-year warranty from Siglent does provide peace of mind that this unit is built to last.
The Siglent SPD3303X-E is the right choice for professional engineers, serious electronics labs, and advanced hobbyists who need clean power, multiple outputs, and remote control capabilities. If you work with sensitive analog circuits, audio equipment, or RF projects where power supply noise matters, the linear design delivers the clean output those applications demand. It is also ideal for anyone who regularly needs to power multiple circuits simultaneously and wants the convenience of a single integrated unit.
The investment is significant compared to single-output switching supplies, so make sure you genuinely need the triple-output capability and linear performance before committing. The display is very bright with no brightness control, which can be distracting in dimly lit workspaces. Firmware updates require a Windows PC and a USB connection — there is no network-based update mechanism. If you primarily work with digital circuits at common voltages, a more affordable switching supply will serve you just as well for a fraction of the cost.
Picking the right bench power supply comes down to understanding what you will actually use it for, not just buying the one with the highest specs. I have seen too many beginners overspend on features they never use, and just as many experienced makers struggle with a supply that cannot handle their projects. Let me walk you through the decisions that actually matter.
This is the single most important distinction, and it is one that confuses a lot of newcomers. A linear power supply uses a large transformer to step down AC voltage and then regulates it through analog circuitry. The result is very clean, stable output with extremely low ripple and noise — think of it like a filtered water supply with zero impurities. Linear supplies are what you want for audio circuits, RF work, precision analog measurements, and any application where power supply noise could interfere with your signals. The tradeoff is that linear supplies are heavy, bulky, and more expensive per watt.
A switching power supply converts AC to DC electronically at high frequency, which allows for much smaller transformers and higher efficiency. Switching supplies are lighter, more compact, and significantly cheaper for the same power output. Modern switching designs have gotten very good — the ripple and noise levels on units like the Jesverty and HYELEC are perfectly acceptable for 95% of electronics work. For Arduino projects, digital circuits, motor driving, battery charging, and general prototyping, a switching supply is the practical choice. If you are not doing sensitive analog work, go with a switching supply and save your money and bench space.
Most hobbyist and general electronics work stays well within the 0-30V range, and the sweet spot for current is 5A to 10A. Here is a quick reference based on common projects: Arduino boards need 5V at under 1A, Raspberry Pi units want 5V at 2-3A, standard analog circuits typically run between 3V and 15V at under 2A, and motor testing can draw anywhere from 500mA to 5A depending on the motor. Battery charging is where higher current really helps — charging a large lithium pack at 5A is much faster than at 1A, and a 10A supply gives you room to grow.
If you work with 24V industrial sensors, 48V telecom equipment, or high-cell-count battery packs, you will need a supply that goes beyond 30V. The HYELEC covers up to 50V, and the Jesverty SPS-6005 reaches 60V. For most people starting out, a 30V/10A supply like the Jesverty SPS-3010 or the NICE-POWER SPS-C3010 is the right starting point. You can always add a higher-voltage unit later if your projects demand it.
Never buy a bench power supply that lacks proper protection circuitry. At minimum, look for over-voltage protection (OVP), over-current protection (OCP), and short-circuit protection. These features prevent damage to both your supply and the circuits you are testing. Thermal protection is important if you plan to run at high currents for extended periods — it shuts the unit down before overheating damages internal components.
An output enable/disable switch is one of those features that sounds minor until you have it. Being able to set your voltage and current with the output off means you can double-check your settings before applying power to a delicate circuit. Every unit in our roundup except the Kungber has an easily accessible output switch. Current limiting is another critical feature — it lets you set a maximum current so that if your circuit has a short or draws too much power, the supply will limit the current rather than letting your components burn up.
A 4-digit LED display that shows voltage, current, and wattage simultaneously should be considered standard. Being able to read your output to 0.01V and 0.001A gives you the precision needed for most electronics work. Coarse and fine adjustment knobs are much better than single knobs because they let you make large adjustments quickly and then fine-tune to your exact target value. Encoder-style knobs, like on the Kungber, offer better precision than potentiometer-based controls.
Memory presets are a feature that experienced users swear by. If you frequently switch between the same voltage and current settings, being able to recall them with a single button press saves time and reduces errors. The HYELEC has three memory slots, and the Siglent can save five different setups. A USB charging port on the front is a small but appreciated convenience that lets you power your phone, a small speaker, or other USB devices without reaching for a separate charger. For more on setting up your complete electronics workspace, our guide to hot air rework stations for SMD soldering covers another essential tool you will want alongside your bench supply.
The Jesverty SPS-3010 is the best bench power supply for most hobbyists. It delivers 0-30V at up to 10A (300W), has automatic constant voltage and constant current mode switching, a 4-digit LED display, and a USB charging port. It holds the number one spot in the Lab Power Supplies category with over 1400 reviews and a 4.5-star rating. For hobbyists who need higher voltage capability, the HYELEC HY50-06A goes up to 50V and adds memory presets for saving common settings.
The NICE-POWER SPS-C3010 is the best bench power supply for beginners because it offers the full 30V/10A specification at the lowest price point in our roundup. It includes an output on/off switch for safe circuit connections, C.V. and C.C. automatic mode switching, a 4-digit LED display, and comprehensive protection features. Beginners get all the essential capabilities without paying for features they may not use yet. The Jesverty SPS-3010 is also an excellent beginner choice if your budget allows, thanks to its proven reliability and massive review base.
The NICE-POWER SPS-C3010 is the best budget bench power supply. It delivers 300W of power (0-30V, 0-10A), features a high-precision 4-digit LED display, and includes safety protections like over-voltage, over-current, over-temperature, and short-circuit protection. It also has a dedicated output switch and a 5V/2A USB charging port. Despite its low price, it maintains accuracy within 0.05V across the voltage range, making it a genuine value rather than a compromise.
Linear bench power supplies use a large transformer and analog regulation to produce very clean, low-noise output with minimal ripple. They are heavier, bulkier, and more expensive but ideal for audio circuits, RF work, and precision analog applications. Switching bench power supplies convert power electronically at high frequency, making them lighter, more compact, and more affordable for the same power output. Modern switching supplies like the Jesverty and HYELEC have low enough noise for 95% of electronics work including Arduino projects, battery charging, and digital circuit testing. Choose linear for sensitive analog work and switching for everything else.
For most hobbyist and general electronics work, a bench power supply with 0-30V and at least 5A to 10A output covers the vast majority of projects. Arduino boards need 5V at under 1A, Raspberry Pi units need 5V at 2-3A, and most analog circuits run between 3V and 15V. Battery charging benefits from higher current (5-10A) for faster charge times. If you work with 48V telecom equipment, industrial sensors, or high-cell-count battery packs, look for supplies that reach 50V-60V like the HYELEC HY50-06A or Jesverty SPS-6005. A 30V/10A supply is the best starting point for most people.
Finding the right bench power supply does not have to be complicated. For most hobbyists and electronics makers, the Jesverty SPS-3010 hits the sweet spot of performance, reliability, and value — it is the unit I recommend first when anyone asks what to buy. If you need higher voltage or memory presets, the HYELEC HY50-06A is an outstanding upgrade. And if you are just starting out, the NICE-POWER SPS-C3010 gives you everything you need without overstretching your budget.
For professionals and serious lab users, the Siglent SPD3303X-E is in a league of its own with triple outputs, linear-grade clean power, and remote control interfaces. No matter which unit you choose, having a proper variable DC power supply on your bench will transform how you build, test, and debug electronics projects. Every model on this list has been vetted through real-world use, and any one of them will serve you well in 2026 and beyond. Pick the one that matches your voltage needs, current requirements, and budget, and start building.
