I like this product - RECONSIDERED
on September 24, 2017
I like this product. Because of other reviews, I tested it carefully while I could still return it.
I rand down my car battery on purpose and this device had no problem starting it - as long as I followed the directions.
In charging and running my cellphone on an extended trip, it did not do so good. The GPS seemed to be demanding on the phone battery, and this device was completely depleted before the trip was complete (5 hours) But so far as recharging the battery, it does fine.
It has not quickly lost a charge sitting unused in the car.
So, to me, it is well worth the money as an emergency car starter. A lot better than the old fashioned battery charger - or even AAA.
UPDATE Dec. - After having this product for about 5 months I am going to have to agree with many of the others who reported problems. While the unit keeps its charge for a long time, it was very difficult to get it attached to the car battery in such a way that it would actually start the car. I ended up calling AAA more than starting the car myself. Also when used to charge a cell phone, even when it was at peak power, it would be exhausted long before the phone was charged. And finally, it is now not even accepting a charge itself.
I have to withdraw my endorsement of this product completely.
