DC Power Supply Variable 60V 5A White - Encoder Knob Control

Our review of this compact bench supply finds it best suited for hobbyists and small lab benches who need precise, portable DC power. The single biggest reason to consider it is the high-precision encoder knob, which makes setting voltage and current far more accurate than typical rotary pots; combined with a clear 4-digit LED readout and an output enable/disable button, it is a practical workhorse for electronics repair, testing small circuits, and charging devices. The unit balances accuracy and size without becoming an awkward desktop appliance.

Key Features

• High-precision Encoder Knob: The encoder allows you to press to select a digit and turn to change each digit 0-9, letting you set voltage and current with fine resolution.
• Output Enable/Disable Button: A dedicated output button prevents accidental powering of the load and lets you safely enable or disable output without changing setpoints.
• Overcurrent Protection (OCP): When OCP is enabled the supply will stop output and sound an alert if a short or overcurrent condition occurs, protecting both the supply and connected equipment.
• Precise 4-digit LED Display: The high-definition display shows readings to 0.01 V and 0.001 A and automatically indicates constant voltage or constant current mode.
• USB Fast Charging Port: An 18W USB quick-charge port is built in so you can charge phones or tested devices without a separate charger.
• Compact and Lightweight: At just 7.51 in x 3.56 in x 5.81 in and about 2.47 lb, it saves bench space and is easy to carry between workstations.

Who It's For

This DC power supply is aimed at electronics hobbyists, technicians doing repairs, and small lab users who value compact gear and precise numeric control. The encoder knob and fine-resolution display are especially helpful when tuning low-current circuits, calibrating sensors, or bench-testing prototypes.

Those who need very high power, multi-output supplies, or professional rack-mounted instruments should look elsewhere; the unit is optimized for portability and moderate loads up to 60 V and 5 A rather than high-capacity bench power systems.

Pros & Cons

Pros

• Precise numeric adjustment with the encoder knob makes setting targets fast and repeatable.
• Output enable/disable button improves safety and prevents accidental powering of sensitive circuits.
• Built-in 18W USB fast-charge port adds convenient device charging without extra adapters.
• Compact size and light weight free up bench space and make the unit portable.

Cons

• Some users report the maximum delivered voltage can be lower than the rated maximum in practice, which may limit certain high-voltage tests.
• The single-output design is not ideal for workflows that require simultaneous multiple voltages.

Our Verdict

The NANKADF DC power supply is a compact, accurate option for hobbyists and small labs that need fine control and portable convenience. Its encoder knob, clear 4-digit display, and output safety button deliver practical day-to-day benefits, and the included USB quick-charge port is a useful bonus. For moderate 60 V/5 A tasks where space and precision matter, it offers good value; users needing higher capacity or multiple outputs should consider a different class of supply.

Frequently Asked Questions

Can the output be turned off without changing settings?
Yes. The dedicated output enable/disable button turns power to the load on or off while keeping your voltage and current setpoints unchanged.

Does it protect against short circuits?
Yes. When overcurrent protection (OCP) is enabled the supply will stop output and sound an alert if a short or overcurrent condition occurs.

Is the USB port suitable for charging phones?
Yes. The supply includes an 18 W fast-charge USB port suitable for charging phones and small devices while you work.
