T&C:
All the test results displayed on the page are based on our internal testing, subject to different conditions, including temperature variations, humidity levels, and equipment calibration standards. Please note that these results are provided for informational purposes only and should not be considered as conclusive evidence for all scenarios. Data was tested in a controlled laboratory environment and actual user experience may vary.
1. The runtime is based on laboratory tests conducted with common household appliances under normal room temperature conditions. 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 input and output wattage of the Smart Extra Battery will decrease to 100W when ambient temperature is higher than 95°F (35°C).
4. The IP54 water-resistance 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
