EcoFlow Power Station Calculators

EcoFlow sorts its power stations into the RIVER series for carry-around use, the DELTA series for larger loads, and the DELTA Pro series, which it calls a portable home battery designed for home backup. The EcoFlow models in our data run from the 286 Wh RIVER 3 Plus to the 4,096 Wh DELTA Pro 3. X-Boost lets heating appliances such as kettles and hair dryers run above the rated output; it is separate from the surge rating in each spec table. Several DELTA models take extra batteries (the DELTA 2 Max reaches 6,144 Wh with two), and the RIVER 3 Plus and DELTA 3 Plus list a UPS switchover under 10 ms. The table below links each model to its own calculator.
