How to choose a suitable power adapter?
Look at the label on the device, then look at the parameters on the power adapter. It can be used if the input voltage and current are the same as the DC interface. (Note for power adapter selection, it is necessary to follow the power source that matches the selected voltage and the current is equal to or higher than the current required by the appliance)

Precautions for power use
※ The power adapters have marked voltage and current ranges. Please use them in strict accordance with the product's parameter standards. Do not use them across voltages and currents, otherwise your equipment may be damaged. Please know
※ Please pay attention to heat dissipation and ventilation when using, please stop using when the temperature of the adapter is too high, check the reason
※ Do not use in wet or high temperature environment
