This works, but you you have to realize its limitations.

It will let you get enough charge into a well-working car battery in order to start the car.

It will not, however, let you move enough power from one car to another to start a car that currently has an old, broken or worn out "dead battery." For that you'll still need jumper cables, an AC starter or a jump box to get a car going that has a truly dead battery.

This product is a great, safe idea, and it'll let you get a car going when someone let the battery run down, BUT, it will not let you jumpstart a car when its battery has died due to age or malfunction of the battery itself.

To summarize : Great when someone left their headlights on, worthless when someone's battery has given up the ghost for good.

My car battery has died twice due to leaving the headlights on, and both times, it has not been able to help me enough. Both times, it has been fully charged, and it has helped to turn the car alarm and dashboard lights back on. But it does not hold enough power to prevent having to call AAA or ask for a jump. All it has done is caused more aggravation, and it wasted a lot of our time trying to get it to work (1-2 hour from multiple rechargings) instead of just getting a jump from someone (<10 minutes). Worthless as a car charger.
