That is a mini battery booster pack. It is amazing. It will start your car, charge your cell phone, and run your laptop. And it has a flashlight. I was skeptical when I got mine so I disconnected the battery from my truck and used the mini booster to start it 5 times in rapid succession. No problem. They are all over the internet for $50 dollars up to several hundred. Mine is a cheap one and works great. Everybody should have one in their vehicle.
