Works with the Xiegu G90!
This power supply surprised me. I didn't think it would have enough power to power my ham radio, but it did!! It has the necessary 10 amps required for transmitting even though the voltage is 12 volts (operators usually supply 13.8 volts to the G90). It comes with an assortment of connectors and even a reverse polarity wire connector if the device you want to power has a different polarity from the normal operating polarity of the power supply. I'm curious if I can use it to charge my small solar generator? I will have to give it a test and then update my review with that information. Stay tun

Definite Recommend
really like this power supply. It comes with multiple connectors that allow you to connect to most anything. I connected it to my Arduino processor board and it works very well. I love the adjustable voltage with digital meter. Would highly recommend this power supply.

Fine but it gets really hot
Works fine. I just dont like how hot it gets, to the point where I wouldnt be able to keep my finger there for more than a half second. The heat specifically is to the left of the dial. However, i literally just glued an aluminum heatsink and it fixes the problem. You can also just have a small fan blowing at it instead.

Excellent power converter and speed control, all in one.
This power supply worked very well! I used it to power one of my Halloween props. I had needed a power supply to work with my 12 volt DC motor. This component did the job. It not only converts 110 AC voltage to 12 volt DC, it also works as a speed control. It slowed down the motor, and worked as a power converter all in one easy package.

great replacement
power supply on monitor was going out. black screen several times a day, sometimes several times a minute. this thing comes with like 20 something pieces, so it will pretty much fit anything. and the voltage can be adjusted. so useful.

Kinda glitchy
worked great to start, the adjustable voltage is nice but not that accurate. However after a few months had a problem where it wouldn't reach the voltage and was fluctuating wildly and wasn't providing any power. Not sure what was wrong, but after messing with it, it just suddenly worked and has been fine since.

Variable voltage is very cool. 10 Amps, 120 Watts is a huge amount of power for $34
Up to 10 Amp output should work for almost any DC powered. Comes with USB C and Micro USB connectors also.
