excellent a must have
bought this too keep with me just in case I get a dead battery. these are a must have. if you do not have one it will cost you $100 for a road service. It also has a usb to charge your phone. for under 40 bucks you can not beat it. who would have thought that my battery died the day after I got it. went to start it and all I got was click. this actually worked on a 4.0l truck engine. my battery was not totally dead as it made the click noise but dead enough that the windows would not work. I will put one in every vehicle. plus you have power to charge other items if the power goes out. I am more than happy as it all ready saved me $ on a road service call. also has a light which is a great night time bonus.

Reliability is important
I have had this product save me on more than one occasion. As a matter of fact, the day I received it I found myself having to use it before fully charging it. I got my car started and wasn't stuck anymore. I do recommend that you fully charge it before use though. It will help the battery last longer.

Small size powerful use
This is the best jump starter I've ever owned. It compact, light, and very easy to use. I added larger jump clips that still fit in the case. Its easy to store and jumps everything from small car to a work truck with no problem. It jumps fast and holds its charge. I've had mine for over a year and only charged it when it got to 78% after jumping 4 vehicles.

Junk! Never buy!
This is junk! I bought it because all my friends had one. Being a single woman I need something like this well I charged it as they said to do and when I needed it it didn't do anything except make my car freak out. Not dependable! Definitely not worth my trust or my money! By the way I have tried to use it several different times on several different items and I've had the same result every time! I would give it zero but they won't allow you to do that.

Worth every cent
This car jumper was very easy to use. I charged it as directed for the first use. It gets a full battery very quickly. I hooked it up to my dead car battery and it cranked up right away. I was shocked at how well it worked. It is a great investment for the price. And its small enough to fit in my glove compartment. This is a great tool to have at your finger tips when needed.

Get this!
Arrived in a timely fashion. It's completely as advertised and I've already had to use it and it worked immediately. Compact and easy to keep in the car just in case. I highly recommend this product.
