Our verdict
The output button is the feature that matters here. Being able to dial in voltage and current with the output off, then switch it on deliberately, removes the most common way beginners damage a project with a bench supply. Add an encoder knob and a short-circuit alarm and it is a thoughtful first supply for the money.

Getting started with the NANKADF 30V 10A Bench Power Supply
Make the output button part of your routine: output off, set voltage, set current limit, connect the project, then enable the output while watching the current reading. Switch the output off before disconnecting or changing wiring. The short-circuit alarm is a helpful warning, but the current limit is what actually protects the circuit.
Who it's for
Beginners who want the safety of setting voltage and current before enabling the output.

NANKADF 30V 10A Bench Power Supply: common questions
Why does an output on/off button matter?
It lets you set and check voltage and current before power reaches your circuit. Without it, the supply is live the moment it is switched on, so any setting mistake goes straight into the project.
Can you charge batteries with it?
You can charge some batteries using the voltage and current limits, but lithium cells need a proper charging profile and supervision. Use a dedicated charger for lithium batteries unless you know exactly what you are doing.
Is 10A more than a hobbyist needs?
Most kits draw well under 1A, so 10A is headroom rather than a requirement. It becomes useful for motors, LED strips and higher-power projects later on.
