A Must-Have for Emergencies 🚗
This jump starter exceeded my expectations. It’s compact, easy to use, and very powerful. It started my car in seconds without any issues. The built-in flashlight and USB charging ports make it even more practical. A reliable, high-quality product that I highly recommend.

Impressive and worth the money!!!
Several times in a matter of a few months my battery on my Toyota Tundra was dead leaving me stranded in the desert. When I was considering a car battery jumper that would work for my Toyota Tundra and my wife's Honda CRV, I wanted a jumper that would not fail. My friend had a different brand I had to use to jump my truck but after some research I decided to try this unit. I purchased my first one in Jan. 2025 and tried it out on my totally dead battery on my Tundra. It immediately started my truck so I drained the battery again and it jumped my truck the second time. I was sold. So I purchased my second one in Feb. 2025 for my wife's car. To ensure the battery pack's are fully charged, I confirm the charge every 90 days. I am very impressed. Peace of mind is priceless. I will tell you their customer service is excellent and very responsive. I would recommend this car starter to anyone.

Perfect and Reliable
This jumper box is perfect, it’s already saved me a couple of times, and even helped my buddy out too. Super easy to use and a must-have for any car.

Car battery jumper
I love this jumper. It works perfectly. I’ve had to jump myself, and I also helped a lady at the store one day. It’s so easy to use. It holds a charge for a really long time. It says to charge every three months but if you haven’t jumped anything it’s usually still at 100%. It will use about 25% per jump. I’ve also started using it to charge my cell phone. There’s two ports on the front where you can plug your phone in. It also has a flashlight on it.I have AAA but why would I want to wait two hours when I can just jump my car battery myself? You can’t beat the price and I’m amazed that something that is slightly larger than a cell phone can jump a dead car battery with no problems. Get one! You’ll be glad you did.

It's a good jump box, but looses power quickly
It's a good little jump box. It's portable , has a flashlight and USB ports. I've only used it to jump my riding lawn mower.The only reason I'm giving 4 stars is because once the battery drops below 75%, it won't start the mower anymore until I charge it back up to 100%. I wish I could get some more power from it when the battery starts to drain.It works fine, I just have to keep it charged all the time, which might not be ideal if you're using this in a car or truck.

Great value. Works as advertised
Works as advertised. Instructions are clear and easy to follow. Looks like its good for 2 boosted uses on a full charge. Only downside is that there is no charging brick in the box. Just a cable. But it charges off a smartphone charger (15 W)

Great power for the price
Needed a small portable battery jumper and this was it. Had a dead battery on a cat that sat for a period of time and with the booat option it started it right up. Small, portable, and powerful.
