Dependable battery
Battery extension works like it says gives you more time for usage of power station, charges fast and can be used separately as a stand alone power to charge a laptop or phone. Good for camping and road trips .I highly recommend.

Great add on
Excellent addition to the Ecoflow River 3. The river three is unique in its size, as it can handle 600 watts. Couple it with this extra battery, and it takes the power station into a different class at a very reasonable price point.
