FANTTIK T8 MAX Upgrade 4000 Amp Jump Starter, 24000mAh Car Battery Pack for Up to 10.0L Gasoline and 8.0L Diesel Engines with LED Display, 100W Fast Charging, 12V Extreme Safe Lithium Portable

Great unit, used it 2-3 times, no complaints.

I bought this for a winter trip across the Nevada/California desert Mojave Desert. I didn't want to be left stranded should my battery have problems. I didn't use it then, but later, another car's battery died. I used this and it turned the engine over with a vengeance. This thing is powerful, awesome.Now comes the storage and waiting to see if it holds a charge for the next time I need it. I really like the durable case. Highly recommended.

Gave this as a Christmas gift to my husband because he is very hard to buy for and I have been pleased with other things I have purchased from Fantix. Well with this bitterly cold weather his truck would not start so he decided to give this a try. Hooked it up and the battery was only registering 3 so he hit the boost button and the truck started right up. He was super pleased with it and said it was much easier and quicker than dealing with jumper cables or a regular battery charger. Really happy with this purchase

I work in a body shop and decided to go with this since all the professionals jump boxes are twice the price. I’m glad I went with this box. Everyone uses it at work since it’s simple to use. We constantly have dead batteries all the time almost everyday. I’ve had mine for 2 years now and it works perfectly fine. I did drop it and it landed on the cables side of the box so that’s a bit loose now. But still works like new

I’m happy that I purchased the T8 MAX jumpstart battery from Fantik and I do believe it is a high-quality device which I’m going to put in my daughter‘s car for peace of mind.However, when reading the instructions for initial charging, step one says to “Plug the wall charger into the universal socket”.I’m a little disappointed to see that the wall charger is curiously NOT included in this purchase. You have to buy that little slice of technology separately… for another $30.I’ll probably go ahead and purchase the wall charger as well so my daughter is better equipped to manage charging the battery. I can honestly say that It’s really not the extra $ that’s bothering me. It’s just that I can’t help wonder how this wouldn’t be considered an essential component included with their product? So, I guess this is just a heads up for anyone else who might overlook this little detail like I did.*I would still recommend this jumpstart battery, but it could have been a 5 star review otherwise.

Bought 10 months ago. Charged it to 100% when I got it and left it in my trunk. Checked it every few months and it had always maintained 100% charge. Last week I finally suffered a dead battery. Easy to hook up, pack still had 100% charge after 10-11 months. Honda Pilot started immediately on the first try and pack still had 96% charge. Really came in handy. Easier than jumper cables. These definitely work! Learned about these on YouTube from Samcrac and Legit Street Cars channels.

Works on dead battery not on broken battery. When I first used it didn't work? Because the battery had a bad cell. The second time I used it the battery was just low and it worked great.
