My Stanley J5C09 is the Best Jump Starter
The basic function of one of these things is pretty simple: take a car with a dead battery and give it enough of a boost in juice to get the engine to turn over. They certainly beat trying to find and then position someone to get a jump between cars. I use my Stanley J5C09 mainly as a portable dc source rather than a portable jump starter / tire compressor and am very happy with it.
You only need a regular outside extension cord to charge it, no adapter to keep up with. That in itself is 5 stars. It has a DC adapter for the cigarette lighter but that is easily tied to the handle. This is a great Jump Starter, starts a vehicle with a completely dead battery with no problem, the air compressor works great and recharging it requires only an extension cord so you don’t have to worry about having a special charging adaptor for the unit.
