This EcoFlow 298 Wh plug-in battery slides into the side of the GLACIER Classic (and the previous GLACIER model) and turns the cooler into a self-powered fridge. With 298 Wh available on board, food can stay cold for up to 43 hours without a mains connection. The 1.8 kg pack keeps the unit portable and, once inserted, gives the cooler its own solar input so up to 110 W of solar panels can be plugged in directly.

• 298 Wh usable capacity, enough for up to 43 hours of cold storage on the 35 L GLACIER Classic
• Enables direct connection of solar panels up to 110 W without an intermediate power station
• Full recharge in about 2.2 hours on AC mains, when installed in the cooler
• Car charging in roughly 4 hours on 12 V or about 2.1 hours on 24 V
• Rated for 800 charge cycles to 80% of the original capacity
• Slots in and out of the GLACIER quickly, useful for hot-swapping on longer trips
