MODULAR DESIGN: The unique modular design gives you the freedom to adjust the power and portability of EcoFlow RIVER Max within seconds
- MODULAR DESIGN: The Extra Battery doubles the capacity from 288Wh to 576Wh during situations when you need more power. You can also detach the Extra Battery easily for more portability during traveling, outdoor adventures, or any application where you need to power devices on the go.
- RECHARGE FROM 0-80% WITHIN 1 HOUR With EcoFlow’s patented X-Stream Technology, the smart inverter enables a fast rechargeability that takes less than 1 hour to charge from 0% to 80%, and it gets fully charged in 1.6 hours from an AC wall outlet.
- POWER UP TO 9 DEVICES SIMULTANEOUSLY: The RIVER Max can power some devices up to 1800W with the X-Boost mode on, which lets you power about 80% of essential devices like kitchen appliances and DIY tools. Use devices below 1200W for the best product use.
- FAST SOLAR PANEL RECHARGING: The RIVER Max can be fully recharged from the solar panel in 4.8-9.6 hours when using one EF 160W Solar Panel, depending on sunlight conditions. The EcoFlow RIVER MPPT Controller ensures a fast-solar panel recharge rate using Open Circuit Voltage: 10-25V/ 12A max, 200W max input. An Solar to XT60 Solar Cable is included.
The centerpiece of your adventure
Power up to 9 devices at once with all the ports you’ll need. Sporting a 576Wh capacity, you’ll have enough juice to charge your phone 42 times, charge your drone 6 times, or make 24 cups of coffee with a coffee maker. Just don’t drink them all at once.
So Much More Sun
Premium monocrystalline silicon cells provide a high conversion efficiency of 21-22%. Recharge even faster by chaining multiple panels in a series or in parallel.
Recharge freely and naturally when you link EcoFlow's 160W Solar Panel to a RIVER Max portable power station.
