Review: Great peace of mind - Bought this over the NOCO after seeing reviews and videos. I have a Viking jump pack at 1000a and it is more expensive than this unit. I have used the 1000a to jump all of our vehicles when needed, including my motorcycle and my lawn mower, so this unit shouldn't have any issues with anything I throw at it. Lightweight, compact and easily stores in your vehicle. Bought this to keep in my truck. I like being able to jump start the vehicle without needing another vehicle to use jumper cables. Keeps you self-sufficient and gets you out of a jam if you find yourself alone in a remote area. Charges quickly and doesn't lose charge over time like other traditional jump packs. Like other lithium jump packs, they do recommend that you charge the unit every three months to extend the life of the batteries in the unit. Pretty standard.
Review: This lil guy is AMAZING!! - This lil guy is AMAZING!! I had a bad battery, and this started my car up right away! It was so easy to use. It kept my car alive each time until I was able to buy a new battery over the weekend! I will not go anywhere without it now. It lives in my car. I also want to note, I fully charged this device as soon as I bought it in November, used it a hanful of times. It has been in my car ever since. It is now, almost February, and I decided to see if it would power on, and it DID! Not only that, but it is has about 98% charge!

### ⭐⭐⭐⭐⭐ Great Value
*by A***N on March 10, 2026*

For the price, this jump pack is great. I keep it in my work truck and frequently jump start medium duty diesel trucks with it. I usually immediately plug it back in to charge, but its real handy to be able to use it for 6.7L and even 9.0L diesels. I'd buy several of these to have on hand over my NOCO GBX75 which had a battery fail and no longer charges.
