LITHIUM POWER PACK

Keeping gadgets charged can be a challenge if crewmembers bring a range of devices with them. This lithium ion power back from Sealey offers a potential solution to the problem. It’s compact and weighs only 1.5kg, but has a 31,200mah capacity – sufficient to deliver half a dozen full charges for a phone, or to fully charge a typical laptop twice. It can be charged from shorepower, excess solar, or when running the engine under way.
