NOTE:
1)Check Your Device Label: Before ordering, locate the original adapter or device label. The voltage MUST be DC 12V. The current (A) must be ≤2.5A.
(2)Polarity Matters: Most standard devices use Center Positive (+). Some audio equipment or specialized devices use Center Negative (-). If the polarity is reversed, it may damage your device. Please verify the symbol on your original adapter.
(3)Port Size Verification: This adapter has a 5.5mm x 2.5mm DC plug. If your device has a 3.1mm inner diameter port, this plug will be too loose and may not make stable contact.
(4)For Best Performance: Recommended for devices with a continuous power draw ≤30W. Maintaining a 20% power margin (e.g., using with a 23W device) is advised for optimal stability.
