Wefomey 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

This is a high-quality universal adapter that offers a massive amount of utility. The adjustment dial is smooth, and the voltage remains stable once set. It’s quick and easy to swap the tips, and the 72W capacity means it handles larger electronics like monitors or LED strips with ease. My only minor note is that the dial is quite sensitive, so double-check the LED screen before plugging in your device—but for performance, it’s a solid, reliable choice.

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.

Needed to replace a power supply for two different devices, ones which I only use occasionally, but need an external power supply to work, so bought this. The selection of tips is great, as is the reverse polarity adapter, although I would say it would have been better to have a physical switch on the main PSU to reverse the polarity rather than the adapter cable. It you forget you have the adapter installed, you run the risk of damaging the equipment you intend to power. You have to look at the main unit to set the voltage anyway so a switch for polarity would have been helpful. Works well and luckily didn't need to power anything below 3v as this is the lowest setting.

Bought as my daughter lost the charger for her 3d printing pen. Build quality is goodand having multi power dial makes it great for everything.

Plugged it into the batter to charge. It 'popped' got warm. I hadn't even plugged it into the 3 pin socket yet. I tried with the adapter and it sparked when it wasn't even plugged into a 3 pin outlet. Feels pretty sketchy. No thanks

Vesatile and good quality

It's got every kind of connector you could want (AND a polarity converter). Brilliant. Will allow you to resurrect those old laptops/devices or even bin-off all your other psu's and just keep/use this one. Wish I'd found this year's ago.

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.
