Awesome Charger. Complete Charge. Restored weak Battery

i had serious doubts when i opened it, its really very tiny and super light weight, especially compared to ones ive owned in the past. (like 2lbs, instead of 20!) Well so far it seems to work pretty well. Ive used it a dozen times on batteries from new to completely shot. its not going to bring back a toasted battery or jump start a dead one, but overnight it will condition and charge most batteries just fine, i have seen it dump up to 18amps on a really low battery, but seems to average 6 amps most the time. It is automatic with some degree of manual override control, instructions are typical, not great but its easy enough to figure out. Its very compact, lightweight, and functional, excellent for average Joe, probably not for your service garage

Great little battery charger.charged my tractor and skidloader with no problems

Light weight but powerful. Recharged my dead battery in 5 hours and will rejuvenate batteries too. The only drawback is the display is hard to read in outdoor daylight. Set to prober battery type before taking into daylight (Car for example).

The unit analyses the battery's condition and then provides several steps to ensure a good charge and conditioning. Very impressive

4 hours fully charged my Dead battery ...easy to use .. Definitely would buy another one

Total collosal piece of junk do not buy!!!! plug in tryed everything all it does is beep alarm automatic bs no adjustment on the 1 button it has does not work at all you get Chinese junk for what you pay for!!! AVOID and they charge me 8$ to return

2002 Accord. Brought my battery back from the dead, starts like it's better than new. Not bad for $36 after discount.
