Does what it’s supposed to do. Easy accurate docs a little on the small side but good. Easy assembly of case. Using it to control voltage to a trail cam off a motorcycle battery with a solar trickle charger. Nice display and so far does the job fine

I really like the user friendly controls & also the accuracy of the read out too. Working to me like a much higher priced converter in a small package W2HR

I use this as a battery charger and a variable bench power supply.

I have bought 4 of these so far, have used two and have found them to work reliably. Main purpose I bought them for was a homemade heated clothes setup with 3s 12V Li-Ion set up to 5V heating pads. only drawing 40 watts at max and the CC has been great for temp control. haven't pushed it to the 12A max but I can say it has ran at 8A for hours with no problem. I read other reviews that said it would not push out the 12A or the 8 even, but maybe it doesn't perform as well at higher wattage/voltage.

I use these in my electronics lab at work and at home. Very satisfied with DROK's product quality. Will bw buying more. Electronics engineer and extra class HAM radio operator
