Overview
Drivers in harsh winters get a jump pack that warms its own battery before delivering current, so a frozen morning start still works. A status screen walks you through three steps, and the clamps are protected against sparks and reversed connections.
The cold weather pre heat and the readable screen are what make this pack stand out for northern drivers. Engine coverage tops out at mid sized gas and diesel engines, so heavy trucks need more current.
Who it's for
Commuters who face sub zero mornings and want clear on screen guidance will use it most. Owners of large diesel trucks need a higher output pack.
Pros and cons
- Battery pre heat for deep cold
- Clear status screen
- Wall charger included
- Weather and dust resistant shell
- Engine range tops at mid sized
- No tire inflator
- Clamp cable length not listed
Performance notes
Cold weather starts depend on battery temperature, and the pre heat function warms the cells before discharge to restore output. Starting a dead battery relies on peak current through the clamps, which suits engines within its stated range. Recharge speed depends on using the included fast wall charger.
