Sorry if a repost.
I have not seen this extra battery on sale until now. The battery will double the output of the Ecoflow River 3 Plus from 286 to 572 watt hours. The battery attaches to the bottom of the main unit. Remember this is just a small power station designed for low power needs. The Ecoflow River 3 Plus is also a competent UPS with a response time of 10ms.
The battery will also work as a separate charge bank through its USB C connection as well as take a charge through the port or from the River 3 Pro.
If you have and like the River 3 Plus and want a an easy way to increase its capacity this might be for you.
