Jump Starter 5000A, 12V Car Battery Jump Starter (Up to 10.0L Gas or 9.0L Diesel Engine), Battery Booster with 3 Modes Flashlight and Jumper Cable

Starts the car quickly and easily. Compact, well-built, and simple to use. Battery holds a good charge and works exactly as expected. Great to keep in the car for emergencies.

This seriously takes fooooorrrrreeeeevvvvvveeeeerrrrrr to charge, but I am shocked at its performance! I see several reviews stating they got a defective product because it won't charge... I'm betting most of them just didn't wait long enough. Keep in mind, you are charging a device with enough power to jump start a V6, with a teeeeeny tiny little USB cord! Even after reading reviews, I still thought it was taking too long. Seriously, you just need to wait. Mine arrived at 78% and took about an hour to tick up to 79%. Then it stayed there for several hours and I was losing hope, but I decided to leave it overnight based on some of the reviews I read. I looked at it maybe 20 minutes later and it was up to 94%. Then it jumped up to 100% after maybe another 20 minutes or so. It seems like the gauge may just take some time to catch up. I ordered this after I broke my Jeep and the battery died because it ended up sitting longer than I anticipated. I chose this one because it was the only one under $200 that I could get same day. It arrived fast, but I was honestly so nervous this wasn't going to work that I ended up putting it off for days because I just didn't want to deal with returning it and finding something else. I finally decided it was time to stop procrastinating, and I was absolutely shocked that my Jeep fired right up! After jump starting, the battery still reads 100%. This is what makes me think maybe the gauge isn't super accurate. Some reviews state that it only works a few times. Even if that's true, this is still 100% worth the purchase! Other reviews have claimed it's still going strong after many uses, so it's probably a toss-up, or maybe it depends on the vehicle you're jump starting. I plan to purchase another one to have on hand, in case the first one fails. I love that this is small, lightweight, and won't take up a ton of space in my already cramped overlanding setup. I was nervous because the instructions were a little weird (bad translation to English), but it was pretty simple to use. The case is a little crooked, but it's functional and keeps everything together and protected.

Works really good for being so small. Great product for the price. Jumped my car when the battery was completely dead and the jump pack was only at 40%. Really glad I bought it. Also has a flashlight and you can charge stuff like your phone. Comes in nice travel case also. Had two of my tenants buy one after I let them use it. Both me and my tenants were surprised on how well it worked. One tenant got the next size up.

I purchased one of these after using a friends at work to jump my truck. the few times I have used it, it worked just fine. I was skeptical how something so small could turn over my truck engine, but it certainly did. I also carry it in my dry box as a back up starter for my surface drive engine that has a bad stator which does not re-charge the battery while running. It's also great when when any lawn equipment has a dead battery and you don't need to pull out huge old style jump packs or run extension cords out to ac powered jumper/chargers. If the longevity ends up being good, I will be very happy. the only reason I removed one star is because the cables are so so short. Yes I was able to get them on the battery, but you literally need to stretch them apart to maximum length to clamp on the posts. I wish the cables were just a few inches longer and it would be perfect. the charging function is easy to see and the battery level also. We will see how long the battery life lasts as batteries that tend to sit without cycling never seem to last more than a few years. And truthfully, it's not like you use an item like this more than a couple times per year.

Excellent product. Compact, powerful and long lasting. I have a 5.4L V8 with a completely dead battery. I hooked up the jumper and the engine cranked and fired up as if I had installed a new battery. Highly recommend this for your vehicle or for anyone you know that should have one.

I liked the specs on this jumper pack and used it to start my MB that had been sitting outside for 9 months. The battery was so dead it would not take a charge. The car started immediately! Very pleased with this purchase.

This jump starter pack works very well for the price. I noticed that there are many who say it takes a long time to charge and I would have to agree. However, it should be noted that I had better success when I connected it to a USBC non-fast charger to charge this jumper. It worked really well today, I actually jumpstarted my own car and I had to jumpstart my neighbor’s car and it had plenty of power to do so on both of them would still residual energy to continue! This doesn’t have the bells and whistles of some of them more expensive models, but it will get the job done and it will do so without breaking the bank.

Use this for my off road equipment while traveling. It works great on a truck, van, and UTV’s as well as charging smaller devices. Small, compact, portable and capable. Meets all my requirements and is a must have for outdoor enthusiasts wether you’re a hiker, rider, traveler, camper or weekender, get this great ease of mind product.
