How many Ah do you really need ?
KMart have a "jump starter" for $99 - its a box with a motorcycle battery with 2 x 12V outlets, built in LED lamp, can be charged off your car (12 hours it says) and also has a 240V mains trickle charger (36 hours).
Nowhere does it say what the Ah rating is.
For what you get may as well thrash & trash and buy another when its spent.
