The full review
Who it suits
Owners of full-size trucks, diesel pickups, vans and boats, and anyone who wants a starter that can also power a 12-volt tire pump.
Who should skip it
Drivers of compact cars: the GB40 is lighter and rated well above a four-cylinder engine.
What we could not confirm
NOCO's older user guides list much longer recharge times than the current one. We show the figures from the current guide. Operating-temperature limits also differ between editions of the manual.
