The EcoFlow WAVE 2 Add-On Battery provides extended runtime and complete portability for your WAVE 2 portable air conditioner and heater. Designed specifically for off-grid setups, vans, cabins, tiny homes, and mobile worksites, it allows you to run heating or cooling without relying on mains power. Compact, fast-charging, and fully solar-compatible, it’s the perfect upgrade for total freedom and flexibility.
It extends the operating time of the EcoFlow WAVE 2 and makes the unit fully portable without needing AC power. Ideal for off-grid cooling and heating.
Expect approximately 2–3 hours of cooling or 5–8 hours of heating depending on ambient temperature and settings.
You can charge it using AC mains, 12/24V DC, or EcoFlow solar panels. It supports fast solar charging when paired with EcoFlow’s portable panels.
Yes — the system allows pass-through operation, meaning you can heat or cool while charging the battery.
