How to use

Connect the adapter to an appropriate AC mains outlet (100–240V, 50/60 Hz). Verify the device to be powered requires 12V DC and does not exceed 7A consumption. Insert the 5.5×2.1 mm plug into the device’s DC input socket, then switch on the mains supply. Observe polarity and connector fit; if the target device has a different connector type or polarity, use a compatible cable or adapter before powering.

Recommendations

Use the adapter in dry, ventilated locations and avoid covering it during operation. Ensure the connected device’s current draw stays within the 7A limit. Disconnect from mains before cleaning or when not in use for extended periods. For devices sensitive to voltage fluctuations, consider additional surge protection.
