Best for every trip length
NOCO Boost Plus GB40 Jump Starter
Starts a dead car with no second vehicle. The one item that scales to no trip length at all.
The item that belongs in the car for a weekend and for two weeks equally. A dead battery at a remote trailhead with no other vehicles is the scenario cables cannot solve. Keep it charged and keep it in the cabin in winter. See <a href="/road-trip/best-road-trip-gadgets">road trip gadgets</a>.
