I bought the 1200amp one.
It comes with a 240v wall charger to charge it also.
For my 10" goto it hardly puts a dint in the battery after about 2-3 hrs use. I could've got away with the 900amp I reckon but the 1200 was on special for $99 anyway. Mines 10kg but doesn't fit on the base. The 900amp is 7kg
