Stanley J509 500 Amp Jump Starter

This review is based on ~8 months of use. Purchase price was $70.

This starter pack is useful if you have a car that sits a lot, and you cannot use a float/trickle charger (like at an apartment). I telecommute most of the time, so my car battery does not get charged much by the alternator. I noticed that the battery in my car was no longer zippy (starts up fast when the battery is good), so I bought this starter pack to supplement the car battery. I would use it multiple times before I recharged the pack. The car battery eventually became severely damaged (interior lights were completely dead) due to lack of use/charge and this pack started the car up on the first try so I could get to Sears.

Stanley recommends that this pack be charged every month, regardless if it is used or not. After the purchase of a new car battery, the jump pack sat in my car for a while, but still held a charge. It was able to start the car of a stranded motorist after not being charged for weeks.

Note that this starter pack cannot run a tire pump from the cigarette lighter outlet as the amp draw is limited to .5amp. Get a different unit if you plan on using it for this purpose. The LED light is quite dim, but better than nothing when you are on the side of the road without a flashlight.

Buy a short extension cord to charge this jump starter, as it does not come with one.

I am rating this unit at three as I am not sure yet if it is defective, or just not very worthwhile. I bought it about a month ago, and charged it fully as was recommended in the directions. A week later, I had the "opportunity" to use it and it failed to jump start my neighbors riding lawn mower. The battery on the unit did not did not hold a charge. I put a charge on it again, and will see if it holds this time. I should think a week between charging and using should not render the battery so weak as to not start a little lawn mower!

I recently purchased the Stanley Jump Start for myself, and what a great item this is. Totally portable, charges off a common extension cord into your own outlet(s). Not too heavy, many features like a light attachment, a USB port, neatly accomodates the cables. Well worth the price, and I found out about it from my AAA service for dead car batteries. I love it when people share great buys.

Charged it when I received it per instructions. Then when I went to use it... nothing. I tried the battery test and it showed no charge. Got a refund. Also, cables are so short you have to set it somewhere in the engine compartment.

This worked just fine in getting my car with a totally dead battery started. Had to get the jump starter charged overnight first.
