This is a fantastic product!
This is a fantastic product! It saved me already more than once, but also allowed me to jump-start other cars without risking my car!

Works as advertised
It came with 2 charging light bars lit up. I plugged in my 30 watt USB MacBook charger and got it fully charged in less than an hour. My car battery was dying (down to 10 volts even with a trickle charger) and I needed to get to the store for a new battery. I ordered this late at night and got it the next morning. I like that these use lithium batteries instead of lead acid. That makes them lighter and smaller, and should last way longer than lead acid. You can drive these batteries to almost zero charge without killing the battery. Try that with lead acid and you've got a boat anchor. Just using over 50% capacity will shorten the life of lead acid. Plus, lithium will hold a charge longer.

These handy things have saved me multiple times on boats. We'll constructed and easy to use. Not the cheapest but well worth the peace of mind.

I originally bought this to have in case of emergencies and to jump my spare vehicles. I did not think I would need to use it so soon but to my surprise my pickup and suv both had dead batteries at the same time. This device worked flawlessly and jump started both vehicles within the 60 second window. I think everyone should have this! My only minor complaint is I wish the cables were longer.
