   It’s compact, easy to use, and packs a powerful punch. I was able to jump-start my car in seconds, and the flashlight feature came in handy at night. The build quality feels solid, and the display showing battery percentage is super helpful. Plus, the included case keeps everything organized. A must-have for every vehicle emergency kit.

   I got this on sale. It’s small, lightweight, and plastic. I didn’t have a lot of hope for it. But I charged it and put it in my truck. My motorcycle battery had died, key left on accessory, and I was ready to go for a ride. I used this to start it. I was Absolutely Amazed. The first thing I noticed was the headlights got really bright. Starter turn at full speed and the bike started right up. Nothing on the Jump Pack was hot or anything. This thing exceeded my expectation so much I am giving them to my adult kids for Christmas.

   We have tested over 10 batteries and this is the only one that is honest about the capacity to date. Not compact, portable with the case, low brightness, very easy to use, functionality is currently sufficient, excellent value.

   Starts cycling on and off when hooked up to a dead vehicle. It’ll crank the motor for half a second then shuts down and just starts beeping until the unit is reset. Tried charging it, same issue. Need to know if this is normal for the unit and I should just return for refund or if it’s just a bad unit.

   It’s good as the item is handy with the cable that does not entangles with each other. I liked the option of mobile charging and flashlight too which can be good during outdoors.

   With the recent cold snap that came through I had a few occasion where I needed to jump some cars for me and the family. This made easy work of it. Instead of needing another car this simplified the process. Best part of this one is the lack of other features that these other brand load into a jumper trying to get a buy. This is simple without the extra and works very well. The light on it is bright to shine on the engine bay and the battery hasn’t lost a bar after several jumps. More affordable than an eco so I’m happy.

   I’ve used it a few times. My only complaint is it fails when the temperature falls below 20° F. Otherwise, it is very reliable and easy to use.

    It comes in a protective case and let me tell you, the flashlight is so bright!!! I love the multifunction of this tool as well. I haven’t needed to use it to jump a car yet, so I can’t speak on that part. The handles are short so that can be a challenge for some cars whose batteries aren’t the easiest to reach. Other than that, no major concerns at the moment
