Hey guys i want to buy a Motomaster Eliminator 700A Booster Pack it has 2 cigarette lighters on it and a usb port. I was wondering, could i wire up a cigarette lighter plug to my 300 watt kenwood amplifier and run it off the 700 amp booster pack? It claims to be able to start 4 dead car batteries so id think it would work. The battery inside is a 22amp hour AGM......
