Rapptor,

Mick is absolutely correct. just use the cables supplied and plug into your 12volt battery. leave it on overnight and walk away. I charged mine once and used it for nearly 2 years of off and on use. I would leave the country for 6 months at a time and didn't worry about charging when I returned. Maybe I got a super dooper battery pack with mine, not sure but no kidding I didn't charge mine once after the initial charge. I would surmise that with regular use you will have to charge periodically but I haven't experienced that yet.

sorry for the delay,

Buck
