Never get stranded with the app enabled Lithium-Ion Jump-Starter from Duracell. With 1800 Peak Amps this jump-starter is powerful enough to start 4, 6 and 8-cylinder gasoline engines with up to 8 liters of displacement for gas engines and up to 6 liters on diesel engines (up to 50 jump-starts a single charge).

IP65 weatherproof construction is designed for use in all weather conditions including rain, sleet and snow. The integrated 200 lumen LED work-light is essential for jump-starting in the dark and features low, high and SOS modes. PowerHub App: Not only will the jump-starter hold a charge for an entire year but it’s smart enough to notify you when it needs to be recharged.
