Scatach 011 3000A Car Battery Jump Starter,12V Jump Starter Battery Pack (up to 9.0L Gasoline and 7.0L Diesel Engine), Portable Jump Box with 3 Modes Flashlight and Jumper Cable

Jump starts in a few minutes fast and easy to use. Small size huge helper. I love the flashlight. It's a great assistance on the road

I used it to jump start my car that has been sitting in with a dead battery for a year and it worked! It's roughly the size of a cell phone, but I was amazed that it was able to jump start my car. I highly recommend this product.

Simple, straight forward, and easy to use. Perfect for lawn mowers. Also can be used as a power cell for charging phones or tablets in a pinch. Impressed.

So far I have used this twice and it has worked perfectly both times. I charged it as soon as I got it per the instructions and used it that day to jump my old car. After that it sat for probably 2 months before I used it again on the same car. The battery was still at 99% after sitting and had no issue jumping the car. All in all I think this is a good product and a nice piece of mind to have in your roadside kit. The cables are a little short but we're plenty long for my group 58 battery. I don't know if they would be long enough for a group 65 though as that is a very large battery. It's a very simple item to use and maintain. The case is a nice design although could be a little bit bigger.

We got this for our pontoon. It is easy to use and a lifesaver on the lake when anyone gets stranded. Great size being it is compact to store on pontoon. Battery life is awesome too.

When this thing arrived and I saw how small it was, I thought there was no way it was going to work. I knew before I ordered that battery properties were frequently exaggerated and I figured I got taken. But it actually worked!!!! Amazing. The thing is comes in a carrying case small enough to easily fit into a glove box, including the jumper cables. It has a nice display to give you the status of the battery. It has functions to provide emergency lights. It can function as a battery bank for charging miscellaneous USB devices. And it even has a metal point, which I presume is intended for use in breaking a window should a person become trapped in a vehicle. And it actually works!!!! Amazing.The only complaint I have is that the unit seems to have quite a lot of self-discharge. The first thing I did when it arrived was to charge it to full, but the unit was completely dead just 24 or 36 hours later. It's definitely not something you can just throw in the trunk and expect to be ready when you need it. On the other hand, even just one jump is enough for the device to pay for itself. Easy recommendation on this one!

I am very surprised such a small battery can actually jump a car. My 99 Civic battery was dead for almost a month. I hooked this up to it and it immediately​ started. Didn't have to wait at all. I had to use this about 7 times until I was able to drive long enough to fully charge the battery, and I was still above 90% charge on the device. Great little device and highly recommended.

It works very well and is easy to carry, making it especially suitable for outdoor activities. It can be used as a power bank, a flashlight, and can also be placed in the car for emergencies without having to worry about the car suddenly running out of power.
