Quick Answer
If the EcoFlow River runs out of battery, it will automatically switch to an alternate power source, such as solar input, if available. This ensures a seamless transition and maintains power supply to connected devices. The unit will recharge once it receives power from the solar panel or other external sources.
When Battery Runs Low
When the EcoFlow River’s battery level falls below 10%, the unit will enter a low-power mode to conserve energy. In this state, it will only supply power to the most essential devices and reduce non-essential functions to minimize energy consumption. This feature helps extend the battery life and prevent complete discharge.
Recharging the Battery
To recharge the EcoFlow River, simply connect it to a solar panel with a compatible output (e.g., 20V, 12A) and allow the sun to charge the battery. It’s recommended to use the EcoFlow solar panel or a similar third-party panel with a compatible output to ensure efficient charging. Alternatively, you can recharge the unit from a wall outlet using the included AC adapter. When using a solar panel, it’s essential to monitor the charging status and adjust the panel’s angle to maximize energy absorption. As a general guideline, a 100W solar panel can recharge a depleted EcoFlow River battery in around 8-12 hours, depending on sunlight intensity.
