    • Excellent jumper pack.
Style: 1000 Amp
Had no trouble starting 5.6 L V8. I’ve purchased three of these now as presence because I’ve used them to help people inevitably end up, loaning it to them and just ordering another one for myself. From 40% charge it takes a few maybe up to 4 hours to get up to 100%. I’ve jumped a V8 engine up to four times before needing to charge. I definitely recommend having one. Amazon sells a nice aftermarket protective case too. ... show more

    • great jumper
Style: 1000 Amp
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. ... show more

    • Packs a punch!
Style: 1000 Amp
Schumacher is a brand you can trust. I've purchased Schumacher year's ago and the charger was very dependable. When it did finally breathe it's last breathe I purchased the jumper box which I was very happy with and last but not least this little miracle of a gadget. It kinda makes one laugh because you wouldn't believe how much power it has but it works every time. I just love this little Schumacher jump start gadget. I'll definitely keep coming back to Schumacher. ... show more

    • good purchase

Great product. Simple to use and very compact. I bought this primarily to go in my wifes Jeep, and for me to take on long distance motorcyle trips. It charges pretty quickly after the battery is low.

    • Not to hot, not too cold. Just right.
Style: 800 Amp
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. ... show more

    • Good to have for emergencies
Style: 1000 Amp
Have had the jump pack for about a year and have used it a couple times. Got the battery replaced in my car now so it just rides in the trunk for emergencies. One of those things you may only need once in five years, but it got us going when we needed it.

    • Feels like it was built by temu
Style: 1000 Amp
Only jumps a motorcycle when fully charged making it useless for a road trip or a day riding with a sketchy battery. My brother has the old version shumacker....bout thr size of a cellphone. This thing was alot bulkier & felt like junk...no weight to it. My brother's is actually heavier. That's why I went for shumacker...his jumps the bike all the way down to the last lite bar. If I put this ching chang cheaply made fragile thing in my touring pack after one ride it'd be beat to death. They DEFINITELY don't make em like they used to. ... show more

This product not only works but is as powerful as bulkier machines. It has plenty of solid features.
