Pros & Cons
Pros
- ✓ Coarse and fine encoder knobs split whole and decimal values for fast, precise setting
- ✓ Wide 0-30V, 0-10A adjustable range covers most hobby and repair loads
- ✓ Type-C port supplies 5V/3.6A to charge a phone or device under repair
- ✓ Short-circuit protection cuts output and sounds a buzzer alarm
- ✓ Auto-detects 110V/220V AC input, so there is no selector switch to set wrong
Cons

Manufacturer description
The WANPTEK POWER DC bench power supply gives you an adjustable output of 0-30V and 0-10A from a switching regulated design, sized for electronics repair, DIY builds, lab benches and teaching labs. Setting a value is quick because the supply has two encoder knobs. The coarse knob sets the digits before the decimal point and the fine knob sets the digits after it, so you can go from 5V to 12.35V without turning one dial through its whole range. A high-definition four-digit display shows voltage and current as you adjust them. The front panel also has USB and Type-C ports. The Type-C port…
SpecPicks Verdict
SpecPicks scored WANPTEK POWER DC Power Supply Variable 0-30V 0-10A using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. WANPTEK POWER's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
What voltage and current range does this WANPTEK bench power supply cover?
You can adjust the output from 0 to 30V and from 0 to 10A. A coarse knob sets the digits before the decimal point, and a fine knob sets the digits after it.
Can I use it on 220V power, or do I need to flip a switch?
There is no switch to flip. The supply detects 110V or 220V AC input (±10%) on its own, and this upgraded version no longer has the 115V/230V toggle on the rear panel.
Can I charge my phone from the front panel?
Yes. The unit has a USB port and a Type-C port, and the Type-C port supplies 5V/3.6A for charging phones or powering a device you are repairing.
What happens if my circuit shorts while it's connected?
When the load shorts, the supply stops its output and sounds a buzzer. It also has overheating, voltage-overload, power-overload, leakage and grounding protection.
What comes in the box, and can I turn off the key beep?
The box contains the power supply, an output power cord, an input power cord and a user manual. To turn off the key beep, press and hold the voltage knob for a few seconds until it beeps.
Key Features
- Upgraded DC Power Supply: The upgraded DC power supply integrates various advanced functions. For example, precise coding knobs, USB and type-c fast charge, OCP short circuit alerts, high-definition four-digit display and multiple security protection Settings
- Coarse and Fine Coding Knob: Unlike other coding knobs, this bench power supply is equipped with coarse and fine tuning coding knobs, the coarse tuning knob sets the value before the decimal point, and the fine tuning sets the number after the decimal point. The combination of the two knobs greatly improves efficiency
- USB and Type-C Charging Port: One of the major advantages of our variable power supply over other variable power supplies is the addition of the TYPE-C fast charging port, which is different from the normal USB charging port and has a 5V/3.6A output for quickly charging your cell phone or other device, or for charging a device to be repaired
- Short Circuit Alarm: Safety always comes first. When the load equipment is short-circuited, the adjustable power supply will automatically stop the output and emit a buzzer to remind the user. Not only that, the adjustable power supply also has the functions of grounding wire, leakage protection, overheating protection, voltage overload protection and power overload protection
- Wide Applications: The adjustable dc power supply features an intelligent temperature-controlled fan and heat sink for excellent heat dissipation and is especially suitable for laboratory, electronic repair DIY, communication equipment maintenance, products line, scientific research and teaching units
- Packaging: 1 x variable dc power supply, 1 x output power cord, 1 x input power cord, 1 x user manual. Tip: If you want to turn off the key beep, press and hold the voltage knob for a few seconds until you hear a beep, then the key beep will turn off
