AVAPOWCar Jump Starter Battery Jumper Starter Portable Jump Boxes Car Battery Jump Starter Battery Pack with Jumper Cable 1500A for Vehicles (12V 7L Gas/5.5L Diesel Engine), LED Light/USB QC3.0

Works. I wouldn't say it works for the 100 jumps or whatever claimed, but it jumped my SUV with a very dead battery twice. Third time was not successful. Held a charge for at least 6 months before I needed it. Easy to use, easy to charge. Small enough to fit under the car seat. Bought more for both my parent's vehicles and my second car. I wish it came with a hard case, but managed to find a plastic box that fit everything.

These were purchased as Christmas presents, and one field report said it worked well but needed to be charged up first as it didn’t hold the original charge.

Highly recommend

A friend had this handy when our truck battery quit. He started our truck and we new for the price we needed our own!

Great little unit I charged it up to 100% used it and it worked fine

Worked so good I'm buying my teenage nephew one. So he's prepared. I've used mine numerous times.

My hubby drove my Cadillac CTS and then it died mysteriously. He probably left something on. My son loaned me his. I connected it up and in like 2 seconds my car started quickly. I just bought one the same night to keep on hand. What a life saver. It appears to have a light that is solid and flashes for strobe and sos and a usb out probably in case you get stranded somewhere. Love this thing. The one I bought is the same brand and has the blue zipper and was around $40. Worked great for my mid-sized V6 sedan. I would get a much bigger one if I had a truck/crossover. But my son's AVAPOW A17 - $40 version did start up his Audi CrossOver and my Cadillac Sedan. The charging ports are on the end and have water resistant rubber covers unlike the one you have...It did not include the cigarette lighter attachment/or other pop up digital thing but I assume it is a updated version. It charges up super fast.

Bought this for one car but battery died on my 2nd car and jumped it three times and still 3/4 charge left, plus it recharged really fast. Tested on charging my phone and that worked.Only had two weeks, so don't have an opinion on longevity, but the quality look acceptable, instructions clear.Only complaint is that the cables are short so if there is a distance from the + terminal and ground, you should look elsewhere.
