Description
The EcoFlow RIVER Pro Extra is an expansion battery: it does not work on its own. It plugs into the EcoFlow RIVER Pro Extra to extend its runtime, adding extra capacity of reserve with no output sockets of its own (the station manages everything).
Who is this extra battery for?
For anyone who already owns the EcoFlow RIVER Pro Extra and finds the runtime too tight: long weekends, working from a van, longer home backup. You roughly double the reserve without buying a whole new station.
How much runtime does it add?
With extra capacity more in LiFePO4 (long cycle life), you noticeably extend the time before a recharge: another night off-grid, a longer run for the fridge during an outage, or back-to-back work days without mains.
Compatibility: check before you buy
This is the key point: the battery is designed for the EcoFlow RIVER Pro Extra, and only that. It connects with the dedicated cable and the station drives it automatically. Make sure you have the matching station before ordering.
