FAQ:

What is the input voltage range of AC~DC 2USB Charging Board?

Most AC~DC 2USB Charging Boards have an input voltage range of AC 110V to 240V, which is suitable for power standards in most parts of the world. However, when purchasing, users should ensure that the selected power board matches the local voltage requirements.

Why does the charging become slow when I use the AC~DC 2USB Charging Board?

The reason for slow charging may be insufficient output current. Although the AC-DC 2USB Charging Board generally supports an output current of about 2A, if the charging device has higher requirements (such as a tablet or a fast charging device), a higher current output may be required. In addition, the quality of the power adapter or power cord of the power board may also affect the charging speed. Make sure that the quality of the power cord and plug used meets the requirements.

Does the AC-DC 2USB Charging Board support fast charging?

Some AC-DC 2USB Charging Boards support fast charging (such as fast charging protocols such as QC 3.0 and PD), but not all models have this function. If you need a power board that supports fast charging, please confirm the product specifications and choose a model that supports fast charging protocols.

How to maintain the AC-DC 2USB Charging Board?

To extend the service life, it is recommended to clean the power board regularly to avoid dust and debris. Make sure that the power board is not overloaded during use and avoid exposing it to high temperature or humid environments. Check the connection ports and cables regularly to ensure that there is no damage to keep the device in good working condition.

What should I do if the power board is seriously overheated?

The power board may generate a certain amount of heat when used for a long time or under high load. If you find that the heat is serious, you should stop using it and check whether it is overloaded or the ambient temperature is too high. You can try to move the power board to a well-ventilated place, or use a heat sink to assist in cooling. If overheating continues to occur, it is recommended to check whether the power board is faulty or not compatible with the use environment.
