Having a portable jump starter is convenient insurance against getting stranded in the biting cold or scorching heat. A portable jump starter, sometimes called a power pack, is typically a sealed, maintenance-free battery itself with jumper cables coming out of one side. Portable jump starters need to be charged every so often to deliver maximum power, but their small size makes them easy to transport.

Although it offers over-voltage, short-circuit, over-current, and overload protection, the LOFTEK 1000A Portable Jump Starter does not have a waterproof case.
As of this writing, the LOFTEK retails for $65.00 on Amazon. The LOFTEK currently has an Amazon customer review rating of 4.5 out of 5 stars, making it one of the best jump starters for the price.
