## Long description

Battery EcoFlow EFEB300 LiFePO4 28V 286Wh is a compact expandable battery designed to extend the runtime of compatible EcoFlow RIVER series portable power stations. With LiFePO4 chemistry and a nominal voltage of 28 V, this accessory adds reliable energy storage in a black, portable housing and is suitable for camping, backup power and mobile work where extra capacity or an independent lightweight power source is needed.
Advantages
The EB300 increases available capacity for the RIVER 3 Plus and offers an additional 140W USB-C input/output port to broaden charging and recharging options. It connects to the main unit via a wireless pogo pin connection without cables or screws and can be used independently to reduce carried weight. The LiFePO4 cell chemistry provides long cycle life and stable performance, supplied with a multi-year warranty for extended use.
Suitable for
Extending runtime of EcoFlow RIVER 3 Plus during camping or outdoor trips
Providing additional backup power for small household devices or electronics
Mobile work where a lightweight, stackable power source is useful
Users who want the option to use an extra battery independently via USB-C
When it may not be suitable
This Extra Battery is designed specifically to expand compatible EcoFlow RIVER series units and may not be suitable for power stations from other brands or incompatible models. It adds capacity but is not a standalone high-capacity power station for long-term whole-home backup needs.
Key specifications
Battery chemistry: LiFePO4 (LFP)
Nominal voltage: 28 V
Usable capacity: 286 Wh
Weight: 3.5 kg
Colour: Black
Additional USB-C port: 140 W input/output
Connection: wireless pogo pin interface (no cables or screws required)
How to use
Stack the EB300 onto a compatible EcoFlow RIVER 3 Plus unit to expand its capacity; the wireless pogo pin connection automatically links the Extra Battery to the main station. You can also use the EB300 as an independent lightweight power source by charging devices through the built-in 140W USB-C port and recharging the battery via the same USB-C input or through the RIVER unit when attached. Follow the manufacturer’s charging guidelines and warranty instructions included with the product.
What to consider before purchase
Ensure compatibility with your EcoFlow RIVER model (designed for RIVER 3 Plus and compatible RIVER series units)
Consider whether 286 Wh additional capacity meets your runtime requirements or if a larger battery option is preferable
Account for the added weight of 3.5 kg when planning portable or backpacking use
Usage recommendations
For flexible outdoor use, keep the EB300 charged before travel and attach it to the RIVER 3 Plus when extended runtime is needed; use the 140W USB-C port for fast charging of compatible devices and follow EcoFlow instructions for stacking and charging to maximise battery life.
