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.
Frequently asked questions
Which power supply does the TP-Link TL-SG105 use?
The TL-SG105 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.
Can I use a power supply with a higher amperage rating?
Yes. The device only draws the current it needs. A higher amperage rating is safe. Never use a higher voltage.
Is this an original TP-Link power supply?
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.
