Great emergency power supply
I’ve been using this for several emergency applications over the last 6 months and worked perfectly every time!TV power went, put this in while I ordered another, happy kids.Work flood light charger went missing, no problem as this worked a treat and didn’t have to work in the dark!Love the voltage readout and granular stepping up of the voltage, so clear and easy to use. Great range of adapters.

Very accurate display of voltage
Iâve used this successfully to power a robotic lawn mower I bought without a charger. As itâs not waterproof I have to keep inside but able to select the correct voltage for charging. Much cheaper than the mowers manufactured one.

Powerline tastic
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.

Stopped working
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….

One PSU to replace them all. Great.
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.

So glad I got this, can power pretty much any device I might come across.

Nice adjustable power supply for micro electronics development. It would be nice if the voltage selector would click into place. The totally analog knob makes it difficult to exactly pick a voltage value.

I am more or less happy with this set, but what really upsets me is that they DO NOT PROVIDE A CASE TO KEEP ALL THE PIECES TOGETHER!!! It doesn’t have to be a fancy thing, a cheap soft-sided zipper case or a clear plastic box that clips shut. This is not my first set of these and every darn time I get them, part of it disappear/gets misplaced so I have heads with no electtrical part or electrical part with no heads. Can’t y’all just package this with a case, please!?!
