The EcoFlow EB300 (286 Wh) expansion battery has been specially designed to adapt to the RIVER 3 Plus portable power station.

Lightweight, robust, and extremely easy to install, it allows you to increase the capacity of your equipment to power your electronic devices, coolers, and portable refrigerators during your getaways in a camper van or out in the wild.

The EB300 battery shines with its ease of use and versatility:

• Cable-free Pogo Pin system: Instantly connect the battery under your RIVER 3 Plus station without screws or cumbersome cables. The Pogo pins ensure smooth and secure energy transfer.
• Independent 140W USB-C port: Thanks to its 140W bidirectional USB-C port (input and output), the EB300 can be used completely independently of the RIVER 3 Plus. Recharge your laptop, smartphone, or drone directly at full speed, or recharge the battery itself via this port.

Faithful to EcoFlow's reputation for safety and durability, the battery incorporates advanced chemical cells:

• 3,000 charge cycles: Lithium Iron Phosphate (LiFePO₄) technology retains 80% of its initial capacity after 3,000 full cycles, guaranteeing up to 10 years of daily use.
• Long-term reliability: Benefits from a 5-year manufacturer's warranty to accompany you with peace of mind on all your road trips.

Weighing only 3.5 kg and with compact dimensions (23.4 x 22.4 x 11 cm), the EB300 battery is the ideal option for travelers who count every kilo and are looking for a modular, practical, and easy-to-carry energy solution.
