NEXPOW 4000A Car Jump Starter, Portable Battery Booster for Up to 10.0L Gas or 8.0L Diesel Engines, 12V Jump Box with Smart Cables and LED Light

Perfect for emergencies! Purchased because the battery kept draining and not cranking. This "magic box" saved us from many dead starts, from one charge. The instructions were a little easy to follow and worked like a champion. I couldn't picture my almost 70 year old mom sitting in 19°f weather waiting for AAA. This box saved us!

Must have for all your cars, trucks anything with a battery that can go dead and leave you on the road!! We have 4 of these and I give them as gifts! I bought my kids these because I didn't want them stranded. Just spent the money you will not regret it!!

Purchase it on a Sunday, arrived as promised by Tuesday. I used it on Thursday morning at a Buc-ee's on the way home from getting gas. The guy had someone pull up on him with cables, I approached him and ask if I could give him a boost because I just purchased this jump starter, shocking by the power it had. Now he's going to get one.

a week after I bought it, I went out to start my truck and the battery was dead I mean nothing not a no-go. Hooked up the charger waited about 2 minutes kicked right over. it was fantastic no having to find jumper cables or push the truck out of the garage to get another car next to it etc it was wonderful well worth the money well worth it!!

after charging the booster fully i hooked it up to the vehicle battery and in a couple of minutes the vehicle started right up without any problems. it is a great purchase to make if no one is around to give a jump from. i would suggest others to get one if they ask me.

i had my doubts with this jump pack when i first got it because of the weight and size. at first it jump started 3 cars from batteries that had 3 volts. on the same charge. then fully charged jump started a 6.6L gas engine 3 times with a failed battery. i am very pleased

Bought at Christmas time for our daughter to have in her truck. My husband has a different brand that was a lot more $$$ than this one so compared, this one is just as good. Her boyfriend has used it to jump off his truck a few times.

car jumper. ordered 4 my wife to have to be able 2 use when I'm not around or already left for work.... haven't gotten 2 use yet, but needless 2 say reviews i read when ordering seemed great 4 what they will be used for

My only problem is that it is that it didn't come with a case so I just leave it in the box. I have another one I got as a present and it came with a case. Disappointed but I still like the product.

never received this item as the stupid delivery person left the package outside of a business that was closed. the stupid delivery person left it at 10pm, idiot
