The EcoFlow River 3 Plus Smart Extra Battery EB300 is a 286 Wh LiFePO4 expansion module designed to extend the capacity and versatility of the EcoFlow River 3 Plus power station. Compact and lightweight at around 3.5 kg, it uses a simple clip-on Pogo Pin connection—no cables or tools required—making it fast and hassle-free to set up. Built with long-lasting LiFePO4 chemistry, the EB300 is rated for over 3,000 cycles to 80% capacity, giving it a lifespan of up to 10 years. A standout feature is its 140 W bidirectional USB-C port, which supports both charging the EB300 and powering devices like laptops or tablets, allowing it to function as a standalone high-capacity power bank when not connected to the main station. Safety is prioritized with protections against overcurrent, overvoltage, short-circuiting, overheating.
