Kraft means power, and this one keeps going as long as the trail does. A high-efficiency panel covers the whole front and trickle-charges the cells whenever it sees daylight — clipped to a pack, propped on a rock or left on the dashboard.

The ports sit behind sealed covers and the shell is wrapped in a shock-absorbing bumper, so it shrugs off drops, mud and a night in the rain. The cord loop doubles as a hang point, and a tap on the side shows how much charge is left.
