New purchase, haven't used it yet, but it will be for my vehicle when needed. 2nd purchased in 2 years and the 1st worked perfectly when needed. This one was fully charged when it arrived.

After a year, the battery died. I bought a new unit and then a replacement battery for the previous unit and after 2 weeks, that replacement battery died.

My grandsons are in scouts and completing their Biking Merit Badge. This portable device is perfect for checking and inflating tires. It is small and convenient to load and unload from the car.

This device has helped me out of a jam several times. Especially with the boat battery. Had to jump it several times when getting to the ramp to take it out of the water. It's worked great on several occasions. Bought one for the business too.

I think I made a great choice. It airs up my tires with little effort on my part. Just set it and it does the rest. I haven’t used all the features but I am sure they will come in handy some day.

Having this in your trunk is like riding with insurance. No matter what happens....dead cell phone....dead car battery or flat tire. It's all covered!

I find this easy to use. I used it to fill my car tire when my tire low light came on. And when someone in the parking space next to me needed a jump I was able to use it again. I highly recommend.

So far this has worked just as described. Happy with its performance, have used it for jump starting a car and putting air in a tire. Wish it had a handle for carrying it with one hand.

Bought to jump start my car it’s a KIA it wouldn’t start it had a friend give me a jump it started right up but it’s awesome for keeping your phone charged when camping.

It could not have came at a better time! I received This jump starter the other day only to find out that my car needed a jump start two days later! You never know when you will need this.
