Triple the Energy for Your RIVER 3 Plus
The RIVER 3 Plus has a standalone capacity of 286Wh. Add the EB600 and you get 858Wh combined, three times the energy storage for longer outages, multi-day off-grid trips, or running larger loads through a working day. The RIVER 3 Plus supports one extra battery at a time, so the EB600 is the maximum capacity upgrade you can add.
Wire-Free Connection & Standalone USB-C Use
The EB600 connects to the RIVER 3 Plus using EcoFlow's wire-free Pogo Pin connection. No external cables, no screws, just stack and clip. The EB600 also works on its own as a 572Wh USB-C battery thanks to its built-in 140W USB-C port, so you can take it on lighter trips and leave the RIVER 3 Plus at home. The EB600 does not provide AC output by itself, only USB-C.
Hassle-Free Connection
Pogo Pin tech connects the EB600 directly to the RIVER 3 Plus. No external cables or screws, just clip on and go.
Extra USB-C Port & Standalone Use
140W USB-C input and output on the EB600. Use it standalone via USB-C for phones, tablets, laptops, and other compatible USB-C devices.
Built to the Same Quality Standard
The EB600 uses the same LiFePO4 battery chemistry as the RIVER 3 Plus, with 3000 cycles to 80% capacity (around 10 years of everyday use before noticeable degradation). EcoFlow's X-Guard protection covers over 40 safety measures across current, voltage, temperature, and circuit risks, with overvoltage, overload, over-temperature, short circuit, low temperature, low voltage, and overcurrent protection built in.
Pairs Well With
The EB600 is designed exclusively for the EcoFlow RIVER 3 Plus Portable Power Station. If you want a lighter, smaller extra battery option, the EcoFlow RIVER 3 Plus EB300 Smart Extra Battery (286Wh) is the smaller alternative at 3.5kg and adds 286Wh of capacity instead.
