Tested it 2X now with batteries that were weak in vehicles, and it allowed the cars to start. Just take it off the battery as soon as it starts, s it doesn't add anything more than a jump.Now, both instances were in warm weather, but I don't believe there will be any problem with your cold weather starts too.Having a light on this is a bonus too!

Compré este jomper por si me falta algún día, pero me resultó más que importante, gracias a este artículo bien chiquito pero cómodo para utilizarlo no me quedé en la carretera y pude llegar a mi destino, se lo recomiendo a todos aquellos que piensen que no se van a quedar botado

Very powerful! Comes with easy instructions. Definitely a lifesaver and a must-have in car for emergencies. Not heavy. It's very easy to use. Doesn't take too much space. I recommend it!

Received the battery pack uncharged. I charged the battery pack so that I could jump start my car. Seemed to charge okay to 100%. It would be a few days before I wasn't working and would be able to spend the time needed to jump start my car. Got to my car, up the pack to my battery to find that the battery pack is dead once again. It does not hold charge. Also, I have battery packs to charge my phone that are much heavier than this thing is. I do not believe that even if it worked that it is a 4000.battery pack. It is as light as a 800 battery pack. Do not buy. This is a cheap, poor quality pack, it doesn't hold charge, and is of poor quality. I have learned my lesson and will be going back to the GOOLOO brand. It holds charge for over 6 months, and I can start diesels with it. I am out of work and was trying to save $40, but it is worth that to know that I will not be left stranded. Again.. DO NOT BUY!

Easy to use, small size, tight battery clips for good connection. The zero volt feature is fantastic, most others won't let you jump a completely dead battery.

I recently purchased the 4000A Battery Jumper Starter Portable and I have to say, I am thoroughly impressed with its performance. This device has come in handy multiple times when my car battery unexpectedly died. The power of the jump starter is incredible at 4000A, it gets my car up and running in no time. Additionally, the 26800mAh battery capacity allows me to charge my devices on the go, which is a great added bonus. The USB C port is convenient and ensures fast charging. The compact size makes it easy to store in my car without taking up too much space. Overall, I highly recommend this product to anyone in need of a reliable and powerful jump starter.

I received this product and found that it worked well sometimes and failed at other times, so it was not consistently working.I was not happy and planned on returning it.The company reach out and offered to allow me to either return it or receive a replacement, and I decided on a replacement.I am hoping the replacement works consistently, but have to say their customer service was proactive and excellent!
