1kWh Battery Extension - For Wave 3 - EcoFlow

This 1kWh additional battery transforms the EcoFlow WAVE 3 portable air conditioner into a completely autonomous solution. Compact and robust, it guarantees up to 8 hours of continuous thermal comfort, without relying on any external power source. Slide it under the WAVE 3, head out in your van, tent, or boat, and enjoy your comfort away from outlets.

⚡ How does the EcoFlow WAVE 3 Additional Battery work?

First, the battery connects directly under the WAVE 3 air conditioner, forming a stable and cohesive unit. Clip it on, lock it, and your portable setup is ready.
Then, it powers the air conditioner autonomously thanks to its 1,024 Wh capacity and long-lasting LiFePO₄ technology. Enjoy a power reserve designed for long evenings at the campsite.
Next, it extends the WAVE 3's operating time up to 8 hours in Eco mode, ideal for a full night of comfort. Sleep soundly, with the side door slightly ajar, a gentle breeze, and controlled temperature.
Furthermore, it can also serve as a power bank for your electronic devices thanks to its USB-A (18 W) and USB-C (140 W) ports. Recharge your smartphone, laptop, drone: your portable battery becomes an energy hub.
Finally, several charging solutions are available: mains, solar, car cigarette lighter, alternator, or via an EcoFlow power station, ensuring you never run out of power. Recharge at the campsite, on the road, or at the port, and set off freely.
