The EcoFlow RIVER 3 Max Plus (Wireless) combines a RIVER 3 Plus (Wireless) with an EB600 extra battery in a single stack, delivering 858 Wh of usable LiFePO4 storage (286 Wh + 572 Wh) and a total weight of 10.3 kg. The integrated 5,000 mAh Qi2 magnetic power bank on top charges a compatible phone wirelessly at 15 W and detaches for use on its own. Three Type F AC sockets share a 600 W pure sine budget (1200 W peak) and are backed by a UPS switchover under 10 ms, protecting a router, a NAS or a small workstation during grid interruptions. Solar input of up to 220 W and a 650 W AC input keep top-ups quick, and the cells are rated for 3000 cycles to 80% capacity.
