This thing is great. It was 50-75% charged when I got it. Plugged it in and it charged totally in under a half hour. Took it to my bot, jumped a dead DEAD battery with the push of a button. Used it later that day at the boat ramp (till I could run the boat and charge the battery). It dropped maybe 1 bar of power. This thing is legit and does what it says.
Its a game changer, life saver! You'd never know your car needs a jump this is a very hand gadget to must have in a car. There are also two usb ports if you need extra jui e for your phones or ur tablet/computer.
Im happy to have this.
Every car driver needs this in their trunk.
It works really good
