NICE-POWER DC Power Supply Variable 0-30V 0-10A - Compact 150W Bench

In this review of the NICE-POWER SPS-E3010 small bench supply, the bottom line is clear: this is a compact, precise 150W DC power supply for hobbyists and light bench work who need adjustable voltage and current in a tiny package. The unit's biggest selling point is the combination of a true 150 W limit with an encoder-based 3-digit display that makes setting voltage to 0.1V and current to 0.01A straightforward. For anyone who needs portability without sacrificing basic lab-grade control, this supply delivers a precise, dependable output in a palm-sized chassis.

Key Features

• Dual-range output: Switches between 15V 10A and 30V 5A modes so the unit never exceeds its 150W capability and protects devices from overdrive.
• High precision display: The 3-digit LED readout shows voltage to 0.1V and current to 0.01A for accurate setting and monitoring of outputs.
• Encoder controls: Rotary encoder knobs let you "set" each digit precisely instead of continuously tweaking a potentiometer, speeding up common adjustments.
• Compact and portable: At roughly 10 x 18.5 x 8 cm and under 1 kg, it fits limited bench space and is easy to move between work locations.
• Universal AC input: 100V-240V 50/60Hz compatibility lets the supply be used worldwide without a transformer.
• Active cooling: A temperature-controlled fan starts automatically to cool the unit and help preserve internal components under load.

Who It's For

This supply is aimed at electronics hobbyists, DIY makers, and field technicians who need a reliable, portable DC source for testing boards, powering small amps or radio gear, and electroplating experiments that stay inside the 150W limit. The precise encoder adjustment and fine current resolution are useful when tuning circuits or providing bench power to sensitive projects.

It is less suited for heavy-duty lab users who need continuous high-voltage or high-current beyond the 150W cap, or for those who require multi-channel outputs or an isolated high-voltage range. Users who need fanless silent operation should also consider other models.

Pros & Cons

Pros

• Very compact footprint and light weight make it ideal for cramped benches or portable rigs.
• Encoder-based digit setting and 3-digit display provide precise, repeatable voltage and current control.
• Universal AC input and automatic fan cooling add convenience and wider compatibility.
• Built-in 150W limit prevents accidental overcurrent or overpower settings.

Cons

• Power ceiling means it cannot deliver both 30V and 10A simultaneously, limiting heavy load use.
• The 3-digit display limits resolution compared with higher-end multi-digit lab supplies for some professional needs.

Our Verdict

The NICE-POWER SPS-E3010 is an excellent value for hobbyists and small-lab users who need a compact, precise, and portable 150W DC power supply. Its encoder controls and fine current resolution are standout features at this price and size. Buy this if you need dependable bench power in limited space; look elsewhere if you require sustained higher power or multi-channel outputs.

Frequently Asked Questions

Can it deliver 30V at 10A?
The unit is limited to 150W, so it cannot supply 30V at 10A; 30V mode is limited to 5A while 10A is limited to 15V to keep output under 150W.

What is included in the box?
The package includes the DC power supply, one output power cord, one input power cord, and a user manual, along with after-sales support.

Is the fan user-controlled?
The fan starts automatically based on temperature; it is not manually switchable and helps protect the unit during sustained loads.
