Hi there,
It is not very safe.
Connecting a 12V / 5A power supply to the Beelink Mini S12 Pro which requires 12V / 3A may not be safe.
The power supply’s amperage (5A) is higher than what the device typically requires (3A). While the voltage is the same, a power supply with a higher amperage than needed could potentially cause problems.
It might not cause immediate damage, but it could lead to overheating, instability, or other issues in the long run. It’s generally recommended to use a power supply that matches the device’s specified voltage and amperage as closely as possible.
To ensure the safety and proper functioning of the Beelink Mini S12 Pro, it would be best to use a 12V / 3A power supply. If the original power supply is lost or damaged, you can try to find a replacement with the exact same specifications or contact us for help.
