I bought two, one come charged at 50% the other at 75% i've not fully charged them from 0% as of yet but i think i read somewhere that it takes up to 3 hours to charge. it fully.

@@k.a.r.a.I charged mine to 100 when I want to jump start I just hook up everything? And try to start or hook it all up and press power button on jumper box?
