Universal Power Adapter 3A 72W Variable Power Supply Adapter AC 100V-240V to DC 3V-24V, Adjustable Power Supply with Polarity Converter and 14 Different Plugs, 3000mA Max

Good PSU lots of adapters and works well just make sure you dont knock the control to a higher voltage when set

Perfect for my application. Voltage control accurate.

My only gripe with this is the LED display is inconsistent with the display of at least one number so the 2 in 12 appears like it's missing a line or two on the display. Other than that, it does the job.

Originally got this to change a 40 year old miners lamp battery as I needed a 4V supply, although the product was probably not intended for this application, it still worked well for me . I have since found other applications for this , good value for money and overall build quality is good, only problem I have is it had one of them small main’s plugs, I replaced that with a standard plug with fuse, that was more of a preference as I find the small plugs difficult to grip and the lack of fuse is disconcerting

Good little unit. Charges well , only criticism is potentiometer is really sensitive. As instructed set up voltage prior to putting charge cable on equipment.

works fine.

Senior moment did not read instructions to item i was powering and product melted. No fault of product.

Easy to use and versatile.
