    great idea compact powerful little device i wish the potentiometers were bigger but thats alright i was a little disappointed due to there being damage on one of the capacitors when i got it so for some reason it boosts my imput voltage too from 32v to 48v till heavy load is applied current adjustment is ticky it seems to be very off and on it will require more testing but may still work for my power supply

    The quality of the regulations, the soldering too, came undamaged. Did n't test

    it’s good I personally use it to charge my lithium battery 7s 6p and it works well, but the heatsink gets warm even in 5amps so i added a 40mm fan and now it runs cool

    Well structured but still to be tested

    the converter works fine.things to consider: 1.)output can never be lower than input voltage (seems like there is a diode somewhere that passes through the input when the output current is too low to keep the voltage up). 2.)overcurrent/shortcircuit protection (red LED) doesnt like it when you start the converter with a load attached (granted i used some 220V AC motors as testloads). seems its already at its limit when it has to charge the output capacitors at the start, as it sometimes triggered without a load attached. i also have the feeling that my Variac had something to do with this(standing 2 feet away), as it didnt happen anymore when i unplugged it 3) output terminals are not very solid, so dont apply too much force when tightening the screws. 4) input capacitors dont have a diode, so power can flow back from the input terminals. so when you put 60V in it will still hold these for a short amount of time. better not touch or short the input terminals after disconnecting from power source

    the Step up looks good and doesnt heed up so much. In my environment i planned to step up 20 v up to 36 with a current of 8 amps. the step up from 20v to 36v wasnt a big problem, i tryt also to setp it up to 50v, that also wasnt a problem. Now my problem, if i Step up 20v to 36 with a current of 8 amps, (shouldnt be a problem cause Constant current range: 0.3-20A and Output power: = input voltage x 10A are both over it..) the volate drops down to about 30v. so the stepup is ok, but not finde cause it have a hard voltage drop if u take to much current amps. Should be fine for about 5A

    I drive my electric bicycle with a 22.2V battery and 2 of these boosters. The bicycle runs on 68 Volts and 14 Amps, so 952 Watts. At first I tried only one booster to step up the voltage from 22.2 to 68 Volts The bike ran alright, but the booster got VERY hot, so I had to slow down every couple of minutes, to let the booster cool down. Then I placed 2 of these boosters after each other. The first one boosts the voltage to 54 Volts. I feed those 54 volts into the second booster which boosts it to 68 volts. Now the boosters stay cool enough and I can drive my bicycle at top speed constantly (36km/h) , till the battery runs out.

    I had high hopes for the dc converter. I needed for a critical project and I was only running 200 watts through it. This thing gets HOT! Like wayyy to hot at 250w to be rated for 1200 watts. I installed a fan on the heatsink and it helped quite a bit, but dont buy this thing thinking you're going to use it for over 800 watts.
