1 | Why does the device fail to connect after 5 minutes once it exceeds the connection distance and needs to be rebooted to connect? | 1. The best Bluetooth connection distance between the power supply and the cell phone is within 10 meters 2. Once the device detects that there is no Bluetooth connection, it will automatically turn off the Bluetooth mode after five minutes to save power, because there will be a certain amount of power consumption when the Bluetooth mode is turned on. Bluetooth mode will be turned on only when the device is restarted. |
The short distance required for a successful connection between Bluetooth and a device is susceptible to interference. |
2 | Why does the device disconnect while in use? | 1. The distance between the phone and the power supply device may be too far or there may be an obstacle (wall, metal door). Please adjust the distance or device position and then check if the Bluetooth connection is restored. 2. If the Bluetooth connection is interrupted for 5 minutes, the Bluetooth mode of the device will be turned off automatically. If reconnection fails, please restart the device and connect again. 3. There may be too many devices connected to the cell phone's Bluetooth at the same time, creating interference and causing the Bluetooth connection between the cell phone and the power device to be disconnected. In order to ensure a successful connection, you can first disconnect the Bluetooth connection of other devices that you don't need to use for the time being. 4. The Bluetooth of the power supply device is version 5.0, please check whether the Bluetooth version of the cell phone and the device is compatible. If the version is the same, the compatibility is better. If the version is not consistent, the connection will be unstable. It is recommended to try again with another cell phone to eliminate compatibility problems. 5. Bluetooth mode may be disabled during use (you may have inadvertently turned off Bluetooth). If the DC and AC buttons are pressed at the same time for 1 second, the Bluetooth mode will be turned off and the connection will be interrupted. 6. If there are interference sources around, please stay away from them (e.g. microwave oven, router, etc.). If there are wireless interference sources around, the Bluetooth connection will be affected. 7. Please check if you turn off the APP inadvertently. e.g. when you use your cell phone to make a call, if you turn off the APP, it will disconnect the Bluetooth. |
