RIVER Max is the ultimate portable power supply for any outdoor adventure. Packing a 600W output and 576Wh capacity, it can keep your favourite devices powered and ready. With its one-of-a-kind modular design, it can be made even more portable by detaching the extra battery pack. For its size, it’s a portable powerhouse ready for use anywhere you go.
Tailored to your needs Thanks to its extra battery pack, RIVER Max’s capacity goes from 288Wh to 576Wh. However, if you need more portability, simply detach the additional battery and go.
Recharge from 0-100% in record time Using a standard plug socket, RIVER Max’s X-Stream feature lets you charge at lightning speed. Reach a 0-80% charge within an hour or a full charge in 1.6 hours.
Use 80% of essential appliances With the ability to use up to 1800W rated devices, you can power the majority of your essential appliances with ease.
Ports and plugs for 9 devices Power a range of devices at once. RIVER Max is equipped with AC/DC outlets, a car port and USB-C and USB-A slots.
Powered by mother nature Use the power of the sun and achieve a sustainable recharge. Hook up one EcoFlow 110W Solar Panel and go from 0-100% in 6-12 hours. Even when the light conditions aren’t up to standard, the MPPT algorithm ensures an optimal recharge by regulating open-circuit voltage.
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 110W Solar Panel to a RIVER Max portable power station.
