EcoFlow WAVE 2 Add-On Battery

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.

Frequently Asked Questions

What does the WAVE 2 add-on battery do?

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.

How long does the WAVE 2 run with this battery?

Expect approximately 2–3 hours of cooling or 5–8 hours of heating depending on ambient temperature and settings.

How do I charge the battery?

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.

Can the WAVE 2 run while the battery is charging?

Yes — the system allows pass-through operation, meaning you can heat or cool while charging the battery.

Is the battery required to use the WAVE 2?

No. The WAVE 2 can run from its power station, AC mains, or vehicle DC. This battery simply adds longer runtime and true portability.

Is the add-on battery compatible with other EcoFlow devices?

No — it is designed exclusively for the EcoFlow WAVE 2 and does not connect to Delta or River series power stations.
