NEXPOW Car Jump Starter 4000A Car Battery Jump Starter Portable Pack for Up to All Gas and 10.0L Diesel Engine 12V Jump Box, Jump Pack, Battery Booster, Portable Jumper Cables with LED Light/USB QC3.0

It’s 6/3/25 when we first had to use this after getting it in 3/24. Battery died in our garage. We have a 2nd car and thought about just doing it the old way, but we had gotten this when my son took this car to college so why not? We have it back as he lives in downtown in a big city now where no one has cars (quite the adjustment!).We check on the charge occasionally so pulled it out, a minute to hook it up and such a fast start! Clean, easy! Super happy with it! Also, charge didn’t even look diminished. My husband pushed the power button and it still said 100%In 3/24, I got this for about $80 on sale. So worth the price! We are going to trade in both cars and go to one new one so these are very handy to have! Obviously my son had this car for 2.5yrs and we lived! We rarely drive it, which might be bad for the battery so we’ll pull it out more!

The Nexpow 4000A is an excellent choice for battery charges and emergency situations. The item provides back-up power when the situation arises.The charger provides ample power and jumps vehicles effortlessly. A full charge provides numerous jump starts. The item is safe and very easy to use!As a purchaser, I would definitely recommend this item without hesitation! The customer service was professional and answered all my questions without delay.

Haven't needed it yet but if looks count for anything, this'll work! It's a much bigger jumper than my last one. But this seems to be a bit beefier and I think packs more of a punch. Hopefully won't need it but I'll be happy that I do should the need arise.

This thing works great! Instead of using a trickle charger on my motorcycle I jumped it using this. Works the first try. I like that it's small and compact. Easily fits in the car for road trips. Definitely beats using jumper cables. Hold a charge 6 months later.

I bought my original unit in 11/2023. It worked amazingly starting my older vehicle that I rarely drive because I work from home. This month, it stopped working. The lights blinked like it was charging, then indicated it was fully charged, but it would not power on. I contacted the company and they went through troubleshooting with me to no avail. They ended up sending me a new unit with minimal questions asked. They are one of the easiest and most pleasant companies I have ever dealt with. Even if the original unit didn't make it to 2 years, their stellar customer service makes them 5-star worthy.

Purchased my 4000A jump starter about 2 years ago. I used it a few times and it worked great. Recently had to use it and found that it would not work. I threw on the charger and it would not take a charge. I contacted NEXPOW and described my issue. They asked for some information on the unit and promptly replaced the 2 YEAR OLD unit. I can't say enough about their responsiveness and attention to making sure I was satisfied. GREAT COMPANY ---GREAT PRODUCT.
