001B 3000A Car Jump Starter Battery Pack (up to 9.0L Gas and 7.0L Diesel Engine), 12V Car Battery Charger, Jump Box with USB 3.0 Power Bank

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.

Had to use the same day it arrived. I have to say I am very impressed it worked perfectly. Jump started my 2007 Chrysler 300c 5.7L hemi with out a problem effortlessly I was back on the road within minutes

I’ve had this for several months now and I have helped out friends with battery issues. This is so convenient especially in situations where you cannot jumpstart with another car. Also it’s much safer than using jump cables with another vehicle. It has other functionalities like flashlights and phone charger The battery life is very good too. I lent it to a friend who was having starting issues (he really needs to by a new battery for his car) and has used it no less than 6 times to start his car over a two week period without recharging. This is great value for the money. Strongly recommend as car batteries nowadays gives no warnings before they die. It’s so easy even your wife can use it 😊

Here is how i got my car started on a fairly new battery. First i put the red and black clamps on then plugged it to the charger to be safe. It turned green. A small light. it boosted it off but it quickly died again. I left it on for a couple of hours and it did not charge it. Brought it in and charge it back to 100%. Took it out to try again. Green light on start car and give rev the car. Died again. Took off the charger. Repeat three more times. Finally got it started but I had to keep my foot on the gas for a couple of minutes.

Nice charger it to 100% fast and comes in a neatly packed bag. But have not needed to use it to jump start yet.

I left the dome light on for a social engagement. It was about 6 hours in all in sub-zero temperatures. When I got back to my car, I saw the light still on, but dimmer than normal. So, I switched it off, crossed my fingers and pushed the start button.Click. And then! Nothing. 😠Luckily I always have cables and knew that since the evening was done others would be out soon and indeed one was. I asked for a jump and he said he would help. Without power however, I could not even unlock the back hatch to get to them, so started to climb through the back seat to lift up the spare tire storage when he stopped me."Don't worry about that." he said then returned to his car to get one of these. We popped the hood, hooked it up and VROOM VROOM (Its a Mazda) started right up! So I just had to have this for my next blunder!On the bright side, I have not had that problem again, but have been near to others with who have! Now I got to be the hero of the moment to give them a start from something in a nice convenient case of portable power! Excellent value!

Works perfect and fast to start battery from my car, thanks

Does the trick as advertised. I've jump started the lawn tractor 2x with good, quick results. Printed owners "manual " is pretty sparse. Not sure how to charge a car or lawn mower battery.
