My battery was acting up yesterday so I ordered this last night to be delivered this morning and my battery was dead when I had to get to work and this did its job! It’s so compact I had doubts but it jumped my jeep and got me in the road! Only used up like 25% of the juice so it seems like this would get like 3-4 jumps out of each charge (although I’m gonna keep it charged up just in case)! It also comes in a really nice carrying case with easy to understand instructions! Thank you! Definitely worth the money to have peace of mind!

I purchased one of these and got a message from Amazon a few days later that it was not deliverable. I think they credited my card (but I am actually not sure). In any case, I really wanted to buy one of these for my husband so I ordered this exact same thing again. It’s important for us to have a gadget like this bc we have only one car so don’t always have another vehicle to charge from. It arrived very fast this time and I hid it away and wasn’t going to get it out until this coming Sunday, my husband’s birthday. Well, the day after it arrived, we went outside to find we had, you guessed it
Arrived on time and It came 75% charged up. I plugged it in and got it fully charged before putting it away. It arrived on Friday, next day on Saturday my Subaru would not start. Read the simple instructions and connected it up was really easy and started on first try. Much easier than the larger battery chargers that need to be plugged into on outlet to jump start a car.The numbers on the screen are large and easy to read and the case is nice for storing in the car.Great unit at a better price than other units with similar power.
I might be really dumb but for some reason it would charge in increments of 5% and I’d have to disconnect and reconnect the clamps to the terminals to start charging again. It did eventually get my truck running so that’s fine with me
It works. My complaint is two jumps brought it down to 50% battery. So expect to charge after every jump. But, it does work well. 4 stars.
Units themselves have been untested to this point so can't say how they will work other than they have held a 100% charge since November 22nd and December 16th up til now, January 14th.When I ordered 1st one the case had an inner divider door in between the 2 sections with a velcro latch to hold it closed over the jump box. The 2nd one came with a case without a divider door, instead it just had an elastic strap across the one side to hold the jump box in. I was very disappointed with the quality of the strap compared to the inner door section of the 1st one. I notified the company and asked i
Works great light weight easy to use and at a good price. A valuable tool to keep in you car.
Small Size, Big PowerI used this for the first time yesterday to jump my wife’s car, which was completely dead. It’s a 2021 Hyundai Palisade. I was honestly impressed—it took less than 3 minutes from opening the case to getting her engine running again.The first thing you notice is the size. It is super small and lightweight compared to the bulky, old-school jump starters I’ve used before. It’s small enough to fit in the middle console of my Suburban, but it packed plenty of punch for a totally drained battery. After that one jump on her car, the jump starter still had nearly 90% charge left f
