Additional Notes
• All test results are based on EcoFlow’s internal lab conditions; actual performance may vary depending on temperature, humidity, and device load.
• Noise and runtime data were recorded under controlled room temperature.
• Battery pack rated IP54 for splash resistance — not waterproof or submersible.

The RIVER 3 Series revolutionizes energy efficiency, delivering up to double runtime for light-wattage appliances, extending use at home and in the great outdoors. Data was tested in a controlled laboratory environment and actual user experience may vary.
1. The “double runtime” claim specifically refers to tests using a 3W light or Wi-Fi router.
2. The noise level data is based on laboratory tests conducted at a room temperature of 89.6°F (32°C). Actual use may have slight deviations due to variations in the real environment.
3. The IP54 water-proof rating applies only to the battery pack, not the entire package. It does not prevent water immersion but can prevent fire or explosion in the event of a short circuit if the battery is splashed with water or rain, ensuring user safety and property protection
