Small but capable
Smaller than I expected but works well. Started a Subaru Outback with a completely dead battery. But its internal battery power went from 100% to 40% During the starting process, so the advice in the user manual to make sure it is fully charged before trying to start a car with a dead battery is best heeded. I did note that when I went to recharge it after the dead battery start, it had rebounded to 85%. If you have USB charger that can provide 9 volts 2 amps, it recharges pretty quickly. If you only can provide 5V, it will take quite a while to recharge.Overall, I am quite pleased. It is compact and easy to use, and it works!

Compact and capable
Great product for the price! Compact with good quality. Came with 75% charged so it worked immediately after it arrived.

Works, more easily than jumper cables and takes up less space in my trunk.
Just used once, but it worked like a charm for my Mazda. Started fully charged, was at 66% after one brief use. OK, but it worked a lot more easily than my jumper cables. No need to be physically close to the starting engine, so way easier to use on a busy street. It’s just way easier to use than jumper cables. Comes with a nice carry case. It recharged to 99% in about 3 hours

Every car owner should have one
Brilliant innovation. Saved me recently until I was able to get a replacement battery. Eady yo use; works as promised. Every car owner should have one.

Excellent, Sturdy and Convenient
I bought two of these for my vehicles. The packages were sturdy and the product looked well made. They charged easily and have both held 100% charge since the initial charging. I used one of them this morning to start a diesel tractor (small engine) that had not been started since last summer and had a dead battery. It started easily and used about 15% of the charged capacity (still has 85%). I would definitely recommend these. They beat jumper cables hands down for a quick start of a dead battery.

Perfect, and Ridiculously Easy to Use
I fiddled with a couple of wrenches and decided there was just no way I was going to extract the dead battery out of my car. Crummy-looking jumper cables were $36. at Walmart; for just a few dollars more I had Amazon deliver this little marvel, and within minutes I was driving down to Advance Auto for a reliably overpriced new battery. Wow, this Jump Starter works great, and it’s lightweight and comes in a nice case. Very nice addition to the “emergency” equipment for a vehicle.

Powerful little punch
Works well and battery remains charged for several months. Used it once after not being charged for 4 months on a 4 cylinder diesel. Started right up and only used 40% battery.Small size that fits well in a glove box.
