Before you hit the trail make sure you have one of these! The Polaris Flex Jump-Starter. It features 12,000 MAH capacity, two 2.1A USB outputs to keep devices charged up, a 200 lumen flashlight, digital battery life monitor and a 1 year warranty. Today’s modern machines are not equipped with a pull start, so don’t get stuck without one of these. Worth its weight in gold at $119.99.
