Check the label on your original TP-Link adapter. It should read Output: 9V DC ⎓ 0.6A with a center-positive polarity symbol. The barrel connector measures 5.5 × 2.1 mm barrel plug. If your adapter shows different values, it is not the right model.
The TL-SG108 is powered by an external 9V DC adapter (5.4W). The original TP-Link adapter can be replaced by any 9V DC adapter with the same barrel connector, correct polarity and at least the same wattage.
Yes. The device only draws the current it needs. A higher amperage rating is safe. Never use a higher voltage.
This is a compatible replacement adapter that meets or exceeds the original specifications, is CE-certified and tested before shipping. It is not manufactured by TP-Link.
