The Webasto BlueCool Hybrid allows shore power to run the company’s bunk cooler while providing hotel load, the company says. BlueCool Hybrid uses a standard 120-volt AC power source. Its components include an electrical cord (12 gauge, rated for 20 amps); a junction box including relays, fuses, and circuit breakers; a 30-amp battery charger; and a 120-volt AC GFCI (ground fault circuit interrupt) receptacle for the vehicle’s interior. When the system detects an outside power source, it switches to “shore power” mode. Electricity from the grid powers the outlets in the bunk, a battery charger and the compressor for Webasto’s BlueCool Thermal Storage unit..
