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.

nice charger. the boost is a little weak for power jumping a diesel with dead batteries but works great to give them a boost when cold starting. only complaint is its hard to change between jump start and charge. it does battery reconditioning and checks the alternator too which is a big plus. well worth the price compared to the over priced others from other stores.

So far it's working as represented.

Very lightweight and easy to use.

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

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

If you want a great jump starter, charger or even a great battery maintainer or rejuvenator, this is your charger. If you are trying to charge a truly dead battery with very low voltage, this one falls short, not even recognizing that it is hooked up to the terminals.

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.

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.

I think this one's defective doesn't work
