So handy!
There when you need it, because it’s sturdy. Functions well because it keeps a great charge. Good value for the money and I’ve had to use it many times.

great jumper
i bought it for my motorcycle, it will work on cars as well, but i bought it to carry on my adventure biking trips, it has already saved me, i was testing my heated gear to see how much amperage i could pull from the stator without killing my battery, and i took it just a but too far, with full heat, heated grips, heated seat, high beams, aux lights and add on fog lights. when i stopped to get gas, my battery had dropped to 11.5 which during cranking went to 10.4 which is not enough to get the computer to turn on.. hooked up the jumper and it ripped right over.. also i can use it as a mobile 12v power bank to heat my heated riding gear away from the bike... and has usb charging ports for other stuff, and the led light is handy as well.. it will be great insurance when im in the middle of nowhere on the bike.

Not to hot, not too cold. Just right.
This has lasted for years and only given me a little trouble over all that time. It's conveniently sized enough to keep handy and works great for the most part. I have had some issues with it keeping a charge over long time periods but if you top it up, it does fine. It also failed to start a battery recently but the battery was completely drained so I don't hold it against the little fella. Even better, this was the only jumpstarter (of 3!) that could even get the battery to draw charge and attempt to turn over. I've had it for several years now, I wish the newer models were this good. Much better value for the money than bigger models.

Awesome battery jumper
Awesome battery jumper. I had one and my uncle liked it so much I got him one for Christmas. Definitely comes in handy when you need it.

It's not reliable.
I bought this to keep in my 87 diesel mercedes. I had to use it one time and it worked fine. I take it out every few months to charge it, and I went to use it and it wouldn't work. Had to tow my car home. I tried charging it and the thermometer icon keeps flashing. Flashlight doesn't work either. It won't charge it's stuck at 79% (but wouldn't jump my car). I wasted good money on this, and it cost me a tow too. I do not recommend relying on this. I have aanother Schumacher jump pack in my truck and I'm probably going to replace that one too. If it doesn't work when you need it to, what's the point?

Me gustó mucho, estoy impresionado como enciende rápidamente una batería totalmente descargada.
