Car Jump Starter - 5000A Peak Jump Starter Battery Pack with DC for Up to All Gas and 10.0 L Diesel Engines, 12V Portable Battery Jump Starter with 3.0" LCD Display

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, a dead car battery. So early birthday gift time, it was. And once opened, we learned how to use this jump starter very quickly and it worked like a charm. It’s super lightweight and comes with about an 80% charge so we didn’t have to wait for it to charge. Just couldn’t have been easier. So we put it to good use that day, it turned the engine over (phew) and we gave it another charge and tucked it away, never thinking we would find our car battery dead *again* the very next morning. Even so, we used the jump starter again and the engine turned over just fine (again) and we were able to drive the car with no issues for the rest of the day. Then on the third day after using it, we went outside to find our car battery dead yet again! We went through the same exercise, charging our recurring dead battery with this brand new jump starter. Again, the engine turned over just fine and we drove it for the rest of the day. That particular night, my husband, feeling super anxious at this point, went outside in the dark to test the engine and saw that there was a very small, very faint dome light on in the back of our car (a Subaru Outback), a light that we didn’t even know existed and that no one would’ve been able to see on in the light of day. Apparently, that light had been switched on inadvertently, and it was draining our battery, necessitating us having to jump-start it with this brand new item that we had only just received from Amazon. So we felt like we figured out where the battery drain was coming from. And this new car jump starter, something we had zero experience with prior to this, got us through this mystifying week without us having to tow it in to the mechanic and pay for all the expensive Subaru “software systems” diagnostics. So glad I ordered another one of these and that it’s now part of our driving experience.

It works great. It's small and fits in my car . I won't go anywhere without it. Definitely worth buying.

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 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 if they could send me a new case with an inner door and said they would but would appreciate a 5 star review. When I received the replacement case, it was totally different yet from either of the 1st two I received. It was physically a little larger in size and the inner door was sewn in place and would not swing back and forth, plus no velcro latch, which wasn't needed because the door would not swing back and forth. I'm not downgrading the jump box because I haven't used them yet and the cases are OK but I feel the quality of the 1st case was superior to the other 2 and for them to possibly change vendors for the cases 3 times in 2 months was a little extreme to me. Hopefully the jump boxes will perform fine when the time comes for me to need them in an emergency. Time will tell.

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.

Small Size, Big Power I 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 for more use. The setup was incredibly simple and intuitive. If you’re looking for peace of mind that doesn’t take up half your trunk space, I can’t recommend this enough. It worked perfectly right when we needed it."
