JS3000 12V 3000A Battery Booster Jump Starter Pack for Up to 9L Gas/ 7L Diesel Engines, Portable Car Battery Charger with Handle Jumper Cable and EVA Protection Case

This bumper box is awesome for the most part. It’s compact enough to carry anywhere- fits under a seat or in a trunk no problem. Like stays on the top of my tool box. Cable length is long enough to reach even heavy duty top wing nut batteries. It works, and it works AMAZINGLY WELL. Attach the cables and the unit auto detects the battery. If it’s low, hold the boost button and start the vehicle. You have about 15 seconds of start time before the boost feature disables.The limited boost time is one of the things I don’t like about it. The jump pack stops throwing voltage after the boost cycle, meaning that if the battery doesn’t have enough charge, everything shuts off. It would be nice to have a fast charger to come with it.That being said, this thing is an awesome value for the money. It started a completely dead 6.7 powerstroke f450. I mean completely dead- oth batteries had 1.5 volts. It started a 7.3 powerstroke that has been sitting on the lot for 5 years. I had to use the pack twice, because the first time was just for fuel priming. Started the truck up both times without issue. If it’ll do that old 7.3, it’ll do any regular vehicle you want it to. It also has emergency lights, and can double as a power pack.

I was having periodic problems with my car not starting. I got a jump from a jump start service who used this device. It worked great. He told me to take a photo of it and that I could get it on Amazon. I went to Amazon and bought it. A week later, the brand new battery I'd bought to replace a two year old battery, was dead. I used this to start it, it was so easy and so fast. Turns out my alternator was bad. . .they think. If it's still something else, I'm covered at least to get started and get to a service. I highly recommend this especially to women. You can easily jump start your car, all by yourself. No matter where you are. Do check it's level of power periodically to insure you have at least 50% charge when you need it. Seriously get this product. If I never use it again, that first simple jump after getting a new battery and the peace of mind it gives me is worth every penny. I am grateful the kid who came to help suggested I take the photo of it so I could get the type he had used.
