Multi-Functional Constant Current Electronic 0-20A 0-200V 185W Optional Discharge Power Supply Battery Capacity Tester, USB Dual Adjustment Accuracy Electronic Load Discharge 15.6 x 13 x 9.6cm

This blew its own power supply electrolytic capacitor blowing the plastic cover off! Lucky my face wasn't in front of it at the time. Could have just been a bad unit but I couldn't take the risk and got a refund. Packaging was also poor with the unit looking out of shape somewhat.

work well for a load tester and the cost aint bad either

Was broken on delivery but a easy repair with two zip ties

It looks like a customer return. The fan and cooling half would not remain clipped to the hot parts, so it could have easily overheated and caused a fire.

The packaging it came in was clearly designed for the horizontal top mount fan/cooler, not the vertical dual fan cooler this one comes with. In the process of trying to get the plastic box to fit, they had managed to damage several of the fins as the fans were pushed and pulled. Given the exposed nature of the PCB as well, I wasn't comfortable having high current voltages (albeit DC) potentially within a finger slip of the controls.Repacked as best I could and returned.

I followed the instructions .....format they are worthing it still broke. Crap

Working well so far. Instructions are basic and using single button for configuration is a bit is a pain.

pile of junk / waste of money100% not accurate complete pile of crap
