Just as your information says ask for a 12 volt 700 ma charger..but seeing that yours is a 450 amp jumper..any 12 volt that fits your ac input will do the job...one more thing if you do not have a charger..just connect it to your battery and run the engine for 20 min or so it will recharge the car battery and you jumper..also you can get a lighter wire with two lighter plugs and charge it through you lighter..good luck
