The Cobra is small enough to fit in the glove compartment, being around the size of a smartphone but it can jump-start most vehicles multiple times on a single charge.
Larger vehicles may not be able to be jump-started with this but check your manual and if it needs 180A/360A peak or less then it will work with the JumPack. There is a built-in LED flashlight to help looking under the bonnet at night and it comes with a charging cable for the JumPack itself that plugs into the 12V cigarette socket. The Cobra isn’t just for jump-starting cars or bikes, it has a USB port and USB to Micro USB cable to charge mobile devices. So if the worst happens and your car and smartphone die at the same time you can at least bring one back, the only thing it doesn’t have is a coin to help you decide which one to go with
