4 out of 5 stars review
Awesome charger with 1 exception.
I've been using this charger for several months and it seem to be the best that I have ever used, very easy to use, has plenty of power to jump vehicles off or you can set for different charge rates. The handle is flimsy it slides into plastic tubes which mine are already broken but if your gentle with it you will be ok, The bad part is a lot of thought went into the design and operation of this unit but they neglected to put battery clamps on that will open wide enough to fit over battery terminals, it's a fight trying to clamp most batteries.
