Jump Starter, 4000A Portable Car Jump Starter Battery Pack with USB Ports, LCD Display, Storage Case, LED Light, 12V Battery Box for Up to 10L Gas and 8L Diesel Engines (001B-4000A)

Immediately starts my 4runner with a v8 engine every.single.time.I bought one of the massive portable car jumpers from craftsman and it took waiting 6 minutes after 2 failed attempts.With this? You could literally have someone sitting in the drivers seat while the other hooks up the jumper to the battery and it will instantly start your car.Light weight, has a case, I carry it in my purse (larger bag for work) just in case.GAME changer. Used to call AAA, wait forever, get told lies (PSA - don’t trust aaa advise. Firstly, their batteries have been having major issues. Secondly, I was lied to that my battery was fine so it must be something wrong with my car and therefor my warranty doesn’t apply…. They also said my battery terminals were an issue and replaced them with (what I would later find out to be) shitty temporary ones. Long story short and $600 in tests later, it was the battery and their replacement temp terminals.Cheapest ease of mind to avoid ever worrying about dealing with AAA ever again for battery issues and their condescending lectures and selling you things that will worsen the problem.

I purchased this for an emergency. I needed it at home. My battery went dead; I mean, I couldn't even use the door opener. I did not think it could start the car right away, but it did. It also started started it a second time a little later. After 2 starts, it still had a 98% charge left. I did not expect that from it. I would recommend this to anyone, good quality and durability, a great deal for the money.

Very impressive. Im a mechanic old school. I keep 1 in every car.I have 3 so far..Good price. Works great. Ez to use.We had a power outage due to a storm and it came in handy. USB ports charged my phone too. Compact i keep it in glove box.Wife use it to help who needed a jump.. Very handy.Ty

I bought this for use in my mother's car. She has a Honda Fit with a tiny battery (my dad's old riding lawn mower uses the same size), and being 81 years old, she doesn't drive it more than once a week or so. Occasionally she'd have to call AAA because the battery didn't have enough starting amps to start the car. AA would jump it and the dealer would tell her to drive it more or get a trickle charger. No garage so no trickle charger. She stopped locking it at home so the alarm wouldn't drain, etc and the problem persisted. Long story short, I bought this to try, mostly for its price point.It worked easily to jump her car at the first attempt. Designed as a power bank too, next winter storm outage I know her phone and Kindle can remain charged. It appears solidly built and has an intuitive design. After jumping her car battery, the unit still read as having a 100% charge which I'd given it before use so I'm confident of its storage capacity but will no more when it has sat unused for some time. It comes with a good hard case for storage, one side for the unit and the other for the jumper cable.I would have given it 5 stars but the jumper cable is very short, too short to set on the car frame safely with the clamps connected, requiring my holding the unit while another started the car.

I’m amazed this little box started my truck with no hesitation 10/10 I would recommend this especially if you’re a women you definitely need this jump box in your possession it’s a lifesaver

Why did you pick this product vs others?:Just pick it

Works like a charm. Thanks

connector for the short car battery cable is loose when I first used the device. Needs a more secure connection. The red light and green light would come on intermittently. finally realized that I had to hold the plug with pressure against the device to get a steady green light. once properly connected, the device worked fine
