Customer Reviews

Lacks an Automatic Float Charging System
This unit should provide the capacity needed to jump start most cars. However, there are a few things to note:

1. This unit does not have an automatic float charging system. This means you can't just leave it plugged in & expect it to maintain a full charge. Instead, you must periodically unplug it and replug it in (at least every few months). If you forget, you will not only not have a charged unit when you need it, but, the battery can become damaged as well if left to fully discharge. Chargers costing as little as $20 have this feature; There's no reason to exclude it on a unit like this.

2. This unit does not include a power cord. Instead, you will need to use an extension cord; it needs to be a single dongle version because of the design of the unit.

3. This unit does not include a storage compartment. Not a big deal, but, if you have some accessories you want to tote (like a power cord or inflation needle), you won't have a convenient place to store it.

I've also had two PowerStation units. One died within a year and the other still works (I think). Time will tell how the Stanley stacks up.

Worth its weight in gold
...and that's saying a lot, since this thing is so heavy.
I haven't used all the features, but I recently had a electrical problem in my car. The alternator was draining my battery, and I had to unplug it every time. I got the jump starter after my car was fixed, but then I forgot to turn my lights off two days later. This thing jumped my car just fine.
I also have a lot of problems with my tires in the winter, air slowly leaks out of one of my tires. This will come in handy then, as well. It'll save me a couple bucks going to the gas station to fill up air.

Pros: It works. Lots of features, including a cigarette lighter charger, USB charger, and air compressor for your tires. Easy to carry with the handle up top.

Cons: Heavy, it takes a long time to charge (15-19 hrs), and you'll need an extension cord to charge it.

Works as advertised
The Stanley J5C09 500 Amp jumpstarter worked as advertised. My car is having an electrical problem that is draining my battery daily. I have used this unit twice and it has worked both times with no issues. I tried one from Oreilly Auto and it didn't work. Thanks Stanley and Amazon for a great product.
