Does it have a power adapter YES

Does it have a power adapter?YES

The power amplifier board is equipped with a 12V/2A DC adapter, which can basically meet your daily use. If you think its output power cannot meet your needs, you can obtain more power output by appropriately increasing the input voltage. The above is the relation­ship between input voltage and output power.

PLEASE NOTE: If the impedance of the speaker you are connecting is 4 ohms, the input voltage cannot exceed 21V, otherwise the power amplifier board will be damaged.
