Glacier Battery Extension - 300Wh - EcoFlow

One click is all it takes: clip in the EcoFlow GLACIER plug-in battery, close the lid, and forget about outlets. Your cooler becomes portable, and your freshness follows you everywhere – in the van, on the water, or at the campsite – keeping essentials cool with ease.

⚡ How does the EcoFlow GLACIER plug-in battery work?

1. Insert. The battery simply slides into its housing, no cables to manage.
2. Power up. The cooler's compressor maintains the temperature; the 45 L stays at +4 °C for up to 39 hours (manufacturer conditions).
3. Recharge. Recover energy from the mains, via 12/24 V on the road, or via solar panels through the GLACIER.
4. Share power. Plug your devices into the 100 W USB-C port
