Car Jump Starter 3000A, Jump Starter Battery Pack for Up to 9.0L Gas and 7.0L Diesel Engines, 12V Portable Jump Box with LED Light

Wow!! This is so easy and convenient! I recently bought a new car and was in the process of selling my old one. After letting it sit for a month without driving it, the battery was completely dead. Not even a click. I didn’t have jumper cables, so I ordered this jump starter for same day delivery. It arrived 99% charged, and I had the car started in under 10 seconds. The battery level only dropped by 5%. So impressed!It’s lighter than I expected, and the built-in flashlight is a smart, practical touch. I'm so glad to have this as a backup now. Technically, I could’ve jumped the old car using my new one if I had cables, but in most situations, you end up needing to ask a stranger. And even worse if you're in an area with hardly anyone around.Never going back to traditional jumper cables again.

This jump starter is a bargain for the price!!! I ordered it once I knew my car battery was dead. I needed to get from point A to point B at least twice before having the time to stop and get my car battery replaced. This little gadget jump started my car battery at least 4 times with the jump starter's battery still ending up at 89%! I'm actually still impressed. Today I went and bought a new gel car battery and all is good. This device took the stress out of everything. Top 10 things I've purchased on Amazon this year, hands down. Even my grandma saw this device in action and now wants one (for real). Thank YOU!!!

This battery charger / air compressor unit is totally something one should have. I needed a boost on my EV cars 12 Volt battery. The battery was dead for over a month in my garage. I finally decided to get this unit to see if it could work. It doesn't advertise I works on EV cars. But, I figure it works on 12 Volt batteries so might as well try it. I just ordered the unit on 4/16/2025. Received it on 4/17_2026. Opened the box and didn't even charge the unit. Connected the cables to the 12 Volt battery and turn the car on. And in an instant the car turned on. This unit is amazing and it really works. Everyone should have one of these and keep it in the truck. It is so nice. Great case came with it. Totally Recommend this product.

This item is small enough to fit in the glove compartment. I bought it for a just in case and have not used it yet.

I have not used to jump my car. I do love that it’s multi purpose! My music car play is constantly shutting off my music streaming from my phone. I plug my phone into this charger and keeps my phone charged and my music playing uninterrupted. The phone barely drains it. It can charge two devices. You would just need to be careful to keep charged up for it’s main purpose. I have used it twice for a few hours it’s still reading 100%. So it won’t need it often.

For the size of this thing, about that of an actual brick, I can't believe it works as well as it does! It's shocking! I wouldn't have been surprised if it wasn't worth the plastic it's made from, but no! It works! My only real complaint is that the lead cables are very short and that means the clamps can't be spread very far from each other. It may be difficult to use on applications with large, wide batteries.
