The EcoFlow RIVER 3 Max Plus combines the RIVER 3 Plus Portable Power Station with the EB600 Smart Extra Battery for a total 858Wh of capacity. That's three times the energy of the standalone RIVER 3 Plus, enough to back up essentials such as a router, modem, small fridge, or home office gear during an outage, depending on the load and runtime required.
Everything else stays the same as the RIVER 3 Plus: 600W AC output (1200W X-Boost surge), under 10ms pro-grade UPS for compatible loads, app control, X-GaNPower efficiency, and the same compact stacked footprint. The EB600 connects to the RIVER 3 Plus via EcoFlow's wire-free Pogo Pin connection with no separate cables or screws, and adds an extra 140W USB-C port. The EB600 can also be used on its own via its built-in USB-C port, but it does not provide AC output by itself. RIVER 3 Max Plus Combined Specs:
