TREKURE Portable Car Battery Jump Starter 4000A 16800mAh Jump Box, Car Battery Jumper Starter Portable Jumper Cables for car(8.0L Gas/6.5L Diesel), Fast Charge, Lights, Compact

This product is amazing. It recharges quickly, and starts the car in under a minute. One day, it was able to jump my Nissan Xterra twice on a single charge. For the price, size, and ease of use, this is a must-have in any vehicle.(My alternator was failing, and the jumps got me through a few weeks until I could get a new alternator. The first time my battery failed, I had to pay $79.95 for road service to use a tool just like this, only bigger. I'm much happier to have my own.)

The unit appears to be solid and well-made. All components were included. It arrived with a 75% charge and charged to 100% in a little over an hour. I have not had the need to use it yet to try to start my car but the USB ports worked well to charge small items. It is small enough to handle easily and I have it in the original box in my trunk but it would fit in the glove box. The instructions were clear and although the print was small, it was readable. For those who have trouble reading small print, I'd suggest writing or typing them out in a form you can read under stress in less than ideal

When people said it jumps your car in 30 seconds, they weren’t lying. This is so amazing, I’m getting another one to keep in my other car. From the time you pop the hood and your car starts is under 5 minutes. No messing with jumping cables or anything. The flashlight on it is really helpful in the dark too! Don’t waste your money on the expensive ones. This one is perfect and compact.

What a great jump starter! This product makes the trickle charger obsolete. Low price! Works great right out of the box. It had enough charge as delivered to jump my car's completely dead battery. Of course, the unit is easy to recharge. Just use your phone charger.

I bought this because my car battery was dead when I was at the barber for my son. His barber had this and it instantly started my car. I went right on Amazon and bought that day. I've had to use it a few times and it works perfectly. I charge it overnight and it keeps the charge for a long time. I usually charge it once or twice a month just to be sure it's ready. It amazes me how quick it works. It works quicker than actual jumper cables! It fits right in my door cubby.

This is lovely, this is very portable and rechargeable. Last very long I’ve tried it two times and runs right away. This also has a built in flashlight with modes that help you in the night of your stuck or if you can’t see in the middle of the night. Has a safety light to make sure positive is on positive and negative on negative.

Really glad I purchased this. Much better than having bulky jumper cables. Very easy to use and started my vehicle right away. Highly recommend.

Perfect for my 2015 Honda Accord. My car broke down and bought this. It has jumped it with zero issues 3 times and still says it has 100% left. Zero issues starting. Cranked up like it would with a full battery. I was debating between this and one costing 3 times as much. I love how small this thing is. I'm sure a more expensive one will be able to jump it more times, but I also get they are larger. I don't need something that can jump me 100 times. Just a few jumps is perfect bc this thing can easily be charged via usbC.Only thing I cannot attest to is how the battery holds up over time.
