This thing went strong (fully charged) for 3 1/2 hours

So far, this thing has been great.

Greatest thing ever

Best thing about this Jump-N-Start is that it is easy to see that this is a well made product and very easy to use.

Love this thing.

Best thing that was invented

This is probably one of the top three things I've ever bought on amazon.com

Charging this thing was annoying- had to get a single ended extension cord (most of mine are 3 outlet) but the most annoying thing is YOU CAN'T RELY ON IT!!I have had this thing for just under two years and now it won't charge >:(

This thing is amazing and I am so glad I had the forethought to purchase this

Best thing I ever bought

I'm speechless, this thing is absolutely outstanding.

We charge this thing like once every 3 months and she still has what it takes to start a full size truck

This thing is awesome

This thing just works!

This is the best thing I ever got it works over and over again every body should get one

This thing does not work

I just bought another one and love these things

I love this thing, for a women it is great to have

This thing is amazing

Plus, it is a great thing for running small electronics in the back yard without dragging out 150' of extension cord.

This is a great thing to have with you all the time

Will update if things change as the winter progresses.

I like this jump starters clean design with no extra things hanging off of the jump starter or unnecessary things like lights or air compressors

Oh, one other really nice thing is that the manufacturer gives you an $85 coupon valid for one repair and shipping costs back to you.

This thing works well.

n’t know if it works yet

n’t work
