Universal Power Supply 3V~24V 3A 72W Adjustable Variable AC/DC Adapter Charger, 100V-240V AC to DC Converter with LED Voltage Display & 14 Tips & Polarity Converter

I initially purchased one as a replacement for the PSU on my cross trainer ( over £110 to get an original) and it works like a dream. Very easy to connect due to the great assortment of adapters that come with it.I was so impressed that I bought a second on to keep in my garage to enable me to test any DC item. Again very easy to select any DC voltage and easy to connect to any appliance with the supplied connectors.

Have two of these power supply now good value a good build quality and size with multi connectors .dose the job well

I’ve used this successfully to power a robotic lawn mower I bought without a charger. As it’s not waterproof I have to keep inside but able to select the correct voltage for charging. Much cheaper than the mowers manufactured one.

This adjustable power supply has been a game changer for my electronics projects! The Wefomey Universal Power Supply offers a wide range of voltages from 3V to 24V, making it extremely versatile. It’s perfect for powering various devices, and the 3A output ensures enough power even for more demanding gadgets.The build quality feels solid, and the adjustable dial works smoothly, allowing for precise voltage selection. It’s also compact and easy to store. Overall, this is an excellent, reliable power supply for the price, and I highly recommend it for anyone needing a flexible power solution.

Worked brilliantly for what I needed at 19v to charge a lap top, went to use it on a 12v light and wouldnt turn back on even after changing fuse.... only a couple months old and past the return time....

Great, used this to power my blink doorbell

Got this as during my house move i some how lost the power adapter for my AOC monitor and for my belkin docking station. sidenote can we normalise monitors connecting with a normal power adapter. these work really well , I like how you can have control over the AC power by turning the dial , to get my docking station and monitor to work , I have to turn the dial all the way up to 11 ( IFKUK) I had to turn it all the way up to the max of 24.4 as the Belkin dock comes with a 75w cable normally if you don't loose it . these stay cool as well I haven't found that they have overheated yet , and they do come with a number of different connections for my dock and monitor I was able to just use the standard connector without attaching any of the ones that it comes with.

Voltage control knob cannot be locked in place, so it is easy to accidentally change the set voltage.Voltage is not directly set by knob, so if device changes resistance/ current/ characteristic then voltage will change without touching knob.
