Audessy 12V 20000mAh Car Jump Starter Booster Jumper Portable Engine Emergency Charger Auto Power Bank Battery Charger

If you own a car this is the item you need in their car and at home, it's the American Express of chargers!! Never leave home without it

This is a very good thing and I like it very much. Whenever my car has any starting problem in winter time, it works very well. Very good all the way.

perfect compact ready to go easy to use I would highly recommend

long battery life on usb, havent tried to jump my car with it yet but its similar to others i have used

works great

It's something everyone needs. They came in very handy.

The biggest selling point to me is the price, it's cheap. I have 2 other boosters and they are much heavier than this. This is super light. My car batt drop to about 8V and I plug this in (fully charged) and the engine turn about twice before it runs, but it ran so it works. I drove it to the destination, let the car run for about 10 or 15mins total. Turn off the engine. About 1hr later I came back out and it won't start again. Plug this booster in and it still couldn't start. I tried it about 3 more times. Than I let it sit with this plug in for a few minutes. Than I start and engine turn about 3 times but it start up. Drove home and plug in my trickle charger. Good price and it does work, just not when the battery super dead. I wonder if I had 2 of this and plug both in, could both able to jump even a super dead battery? The low price I could get 2 instead of buy a single expensive one and put all my eggs in one basket. Another reason I got this because of the AC plug in charger instead of charging through USB.

The charger was smaller than expected. Does not effective charge SUV battery size.

plus side it showed up with a charge negative side would not charge my phone i had it plugged in but it kept turning off i have not even tried to jump a battery

item was advertised as brand new, when it arrived the box had been opened and the contents all over inside the box. security seal broken. obviously not brand new. and the sellers were not helpful and actually quite rude.
