Product Description:
1. Wireless connection problems are not available.
A: When the indicator light is working properly, it will flash regularly. If you turn it on or off, it may have a problem with the module. You can contact our customer service to deal with them.
2. Phone can be connected, but laptop or desktop can not be connected.
A: If your phone can connect and play music, it means that the wireless power amplifier board is no problem. There may be a problem with drivers for wireless function of your computer, too old, or missing files.
3. When you increase the volume, the sound will be interrupted. After the volume is lower, it can be played normally.
Answer: One reason: if the power supply is too small, whether the 18650 battery is installed and the voltage is too low, you can replace a new battery for testing.
Second, because the 18650 battery is not installed, the power is powered directly from the charging port. When charging, the current of the power chip can pass through is relatively small. However, you can skip the charging chip limit and connect the power supply directly to the battery holder.
Third reason: if there is no power problem, the speaker may be too low power. For example, if the output is 3W, connect 1W speaker to increase the volume, then the speaker may cause freezing phenomenon, and the speaker may burn out.
