I wanted a shop quality charger. This one meets that standard. The variable charging modes make this unit. I had a parasitic draw on a brand new battery causing it to degrade and with one of the modes it brought my battery back to life. I'd recommend this unit for the home shade tree mechanic.

Just select what battery you have, and hit the charge battery button. Pretty simple. Plug it up, and CcHHHHAAAAAARRRGGEEE!

Comparing price and quality with other brands.

Stops changing at 12 volts, my own alternator keeps it at 14.8 volts. Jump option does not seem to perform as advertised and the rebuilding battery option, which used to work years ago; now doesn't seem to do anything. it also comes with assembly requirement, for as expensive as it was and the packaging it came in and with i should not have to assemble

Never used it. Too many negative comments about this item. Also seems the circuit board is loose…peeking through the vent on unit. Decided to return than take a chance with it.

did not work kept turning off...

Didn’t work from the time we took it out of the box

This won't change the battery in my van. I also just watched the video on youtube, and the man tried twice to start his corvette, and it didn't work.

It is to complicated to operate and the instructions are not clear how to operate it.

does not work no reset button.
