Extend the runtime of your EcoFlow RIVER 3 Plus Power Station with a compact, cable-free Smart Extra Battery. Available in two sizes—EB300 (286Wh) and EB600 (572Wh)—these modular batteries expand your total capacity up to 858Wh, giving you the freedom to power more devices for longer when camping, creating content, working remotely, or staying prepared during light outages.

Designed for seamless integration, each Extra Battery connects to the RIVER 3 Plus using a wireless Pogo Pin interface—no tools, screws, or cables required. Just click it into place for instant expanded power. You can even use the Extra Battery independently as a lightweight power bank when you want to reduce your load or carry only the essentials.

Both models add an extra 140W USB-C port (input + output), giving photographers, drone pilots, and remote workers more flexibility to fast-charge laptops, cameras, phones, and other high-draw electronics directly from the battery.

Whether you want a simple runtime extension for weekend trips or a larger off-grid buffer for longer stays, the RIVER 3 Plus Extra Battery lets you scale your portable power system to match your needs.
