Awesome! Plenty of jump start power. Purchased 1 from Amazon & another from my local hardware store(same model). Used 4 times in the last few days on our fleet vehicles. Cars/trucks/vans...no problems. Charging is easy on this model, just plug it in with an ordinary household AC extension cord or use the DC adapter supplied. Also, this unit has an on/off switch. My old one didn't so the terminals were 'HOT' all the time. Life saver device, well worth the bucks!

I bought this jumper to jump my motorcycle. The battery goes dead every winter and I am not in an area where I would be able to keep the battery charged over the winter (I am forced to park the thing out on the street). Anyway, this jumper works great - I plugged it in, let it charge for a day (although I don't think it requires a full day to charge) and jumped my bike right up - the battery on my bike was completely dead prior to the jump. Very easy, no problems.

My battery wouldn't hold a charge and I used this every day for 4 months to start my car and it exceeded my expectations. I never expected it to last that long, but with charging once every 3 weeks or so it worked fine. Small, portable, and much easier than jumper cables. Highly recommended.

I use it to start my lawn mower and cars if necessary. So far, it has been working well. It is much better off for me to have this battery pack than buying a dedicated battery for my lawn mower. A great product!

I shopped eBay and major retailers, and Amazon had the lowest price for this item. I had previously read online reviews of similar products and decided that Stanley offered the best, along with a trusted brand name.

Shopping at Amazon is so easy, I do it often.

This is a great product. I use this to jump the mower, ATV, watercraft, etc. Very pleased with this product.

I received my Stanley Amp Jump Starter, charged it and put it to work right away. It works as it should, cars start up right up and the attached light is a great feature. Be sure you have a small extension cord to charge it or you can use the supplied car charger.

This jump starter works as advertised....its not bulky very compact but powerful. I have used the usb port to charge several items. If you need a jump starter, then I recommend this baby, small but gets the job done.

Unit works well enough but it is not a Stanley Product. All the documentaion with the unit list Baccus Global. There is no indication of the country of manufacture. I prefer bying products from the USA and many of the Stanley products list a made in USA stamp.

I recently bought this jump starter, and have found, that if the car does not start on the first few cranks, forget it, the charge is gone from the jump starter, and you have to recharge it, before you can use it again. Not too happy!
