  • Works great
Style: 4000A
Bought to jump my own car battery that was completely not useable because it had died. Read lots of reviews and this Wolfpack was rated highly as it has a super easy to read display on how much juice is left. Not only is it definitely easy to read(Huge display!) but it’s fairly user friendly if you’ve never jumped a car before. It didn’t start my car on first 3 tries but that’s cuz my battery was totally dead. It only sucked out 7% (went from 100% charged to 93%) and the “Boost” option, which entails just pushing and holding a button, made my car start just like it had a brand new factory battery. It also has a really bright flashlight on the end of it that’s either regular or flashes if you have a break down on the side of the road, etc. It also comes with everything you need to charge it (which some other brands do not), and a nice carrying case too! It came already charged to 76% (so plenty to use right off the bat), and only took 40 min to completely charge to 100%. And of course thanks to Amazon’s fast delivery, I ordered this on a Saturday and I had it by Sunday night to try it to make sure it worked so I could use it to start my car Mo day morning to drive to get another battery to replace my crapped out one. All in all, great functionality, and I’d recommend for anyone who doesn’t want to rely on someone else to help you. ... show more

  • Exceeded My Expectationre,
Style: 4000A
Rare that a product exceeds my expectations, but this one did. Ordered it to recharge a dead truck battery, which happens a few times per year because I drive it so infrequently, especially when it gets colder. In the past, have to position another vehicle, open hoods, connect cables (and fidget with them until I have a strong connection), start up the truck, disconnect the cables from both vehicles, and drive the “charging” vehicle back to the carport. The Wolfbox was great. Spent about a half hour charging it to 100% after It arrived. Connected it to the truck battery (could not have been easier), and truck started right away. Only used up 3% of the Wolfpack charge. All within five minutes or less. Quality is superb. Comes with a very nice storage case. It’s lightweight. It will also charge other devices like tablets, computers, and phones. As we live in earthquake country, as well as regions threatened by power outages due to fire, the charging versatility of this device is incredible. There are other much cheaper alternatives out there, but from my perspective, this is worth every penny and more. Rarely offer any kind of product endorsement, but felt compelled to give this one. ... show more

  • Reliable Power on the Go: A Must-Have for Every Vehicle Owner
Style: 4000A
I recently purchased the 12V Jump Starter, and it has already proven to be an invaluable tool. The device can effortlessly jump-started 8L diesel truck, which had a almost dead battery, in seconds. Its 24000mAh capacity is impressive, and the 4000A peak current provides more than enough power for a range of vehicles. The HD LCD display is super useful, offering clear and accurate updates on the battery status and functionality. It comes with a 65W USB-C quick charger , it charge the jump starter in just a little over an hour. I can use the Jumpstarter as power bank for my phone and laptop during a camping trip. LED flashlight especially useful when I had to work in the dark. I just found it has SOS and strobe modes features for emergency situations. Its built is very solid with IP64 rating and all the features make this jump-starter usefull, reliable durable and convenience Highly recommended for any vehicle owner. ... show more

  • effective and easy to use
Style: 4000A
This jump-starter is compact, easy to use, and effective. Leads are a little short but the unit charges quickly and provides immediate and power that seems to be greater than the original battery. I store it in a small bin in my pickup and can use us easier than jumper cables.

  • Gets you out of emergencies
Style: 4000A
Cold weather killed my battery. This was super easy to use and worked well. Type C charging is universal. Probably won’t use the flashlight.
