Unique design With RIVER Max’s modular design you can easily make it more portable. Packing an additional detachable battery, you can remove it whenever needed for extra mobility, ideal for trips and outings.
Charge lightning-fast Spend less time charging and more time in the great outdoors. With X-Stream technology, charge RIVER Max through a standard plug socket in just 1.6 hours.
A rapid renewable recharge Under perfect conditions, recharge your RIVER Max in just 4.8-9.6 hours by connecting an EcoFlow 160W Solar Panel. RIVER Max’s MPPT algorithm regulates open circuit voltage, so you can get a fast but optimal solar recharge.
Ports, ports and more ports With a range of ports built-in, RIVER Max can power up to 9 devices all in one go. It doesn’t stop there. RIVER Max can power heavy-duty appliances up to 1800W too, all thanks to X-Boost technology.
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.
