Use a Portable Power Pack to Jump Start Your Car when you have a dead battery. It's far safer, easier and quicker than finding another vehicle to connect jumper cables to.

Also, if you're alone on a road trip or late and night and there's no one else around, then having a portable power pack may be your only option.

Simply keep it charged by plugging it in every couple weeks, and it is a fully-capable battery ready to supply enough power to start your vehicle even from a totally dead battery.

The power pack also has plug-in cigarette lighter adapters, an LED worklight, and a USB charging port.These can be bought for about $60. This one is from Harbor Freight tools.
