Boost capacity by 3x
Double or triple the capacity of your DELTA Max generator to 4032 Wh or 6048 Wh and thus extend the operating life of your most important devices.
Can be charged anywhere, anytime
The smart additional battery of DELTA Max can be charged with all charging methods offered by DELTA Max. This means you can charge your device anytime, anywhere as long as your spare battery is connected to your DELTA Max. Once the spare battery is connected, both units will be charged or discharged at the same time, so the percentage of battery life remains the same for both.
Prepared for any emergency
The EcoFlow Smart Generator with the 1800 W DC fast charging function (sold separately) is the perfect power generator for blackouts. Simply connect the generator directly to your battery unit via the additional battery connection. This also works if the second battery is not connected to the DELTA Max.
All information at a glance
The smart additional battery has an easy-to-read LCD display on the front that shows you all the information you need, such as output, input, remaining charge and remaining runtime.
