  • Decent charger
Size: 4A/8A Charging Current, 6V/12V DC Output
I bought this charger on sale (like new condition), and was a decently priced as such. Took a bit to understand how it works and what it does and even had a mind to return it but started it liking it and now I’m very happy with it, just took some patience and tinkering.

  • 6-Amp Fully-Automatic Smart Charger
Size: 3A/6A Charging Current, 6V/12V DC Output
The media could not be loaded. What I like the most is the long enough cable from the charger to the battery. My other brand $25 charger's cable was only 2 feet which was too short for my use. I checked both 3A and 6A modes. Both were accurate (see video clip.) The only thing my $25 charger does but this one does not is displaying real time charging current (in Amps). I have been using it to keep my Honda Odyssey battery from dying if I don't drive it for 2 weeks. No issue so far. ... show more

  • Really Impressed by the quality and charging power!
Size: 5A/10A Charging Current, 6V/12V DC Output
First, I was was surprised by the quality of the cables included. I charged both a LiFePO4 and a marine deep cycle , one after the other. Tells you all the info you need during the process. I would absolutely buy again.

  • Very Happy with This Purchase.
Size: 4A/8A Charging Current, 6V/12V DC Output
Very Happy with This Purchase. On our 22-year-old Toyota, we revived a couple of years-old battery. We weren't sure if the problem was with the battery, the alternator, or something else. We tried the Manusage charger before spending money on a battery, knowing it would be useful to have for our other cars, especially when batteries "die" on winter days. Our battery tester produced no results. The dead battery was charged in a matter of hours after a simple hookup procedure. After reading other reviews, we assumed we'd need to keep it running at least overnight and into the next day. We expected to have to remove the battery and use the Repair mode, but we were fortunate this time. ... show more

  • Limited 6V usage
Size: 5A/10A Charging Current, 6V/12V DC Output
6V does not charge at 10amps, and 6v does not have repair function. Hope this helps someone out.
