modem router adapter for power adapter
Good evening. Your TP-Link W8961N V3 modem uses a 12V 1A AC adapter. Using a Huawei DG8245v adapter rated at 12V 1.5A should be safe as long as the power ratings match and the connections are correct. If it works, you can reverse the setup—use the TP-Link adapter on the Huawei modem. Just ensure both adapters are compatible with your device’s requirements.
Change adapters when you have the right one, but avoid reversing the process. If the polarity matches, it’s acceptable. Ensure the adapter delivers the same voltage or more current capacity; otherwise, it should work. It must match the listed voltage and provide enough current—insufficient power is not safe. Using a lower-amp adapter for a higher-draw device is not recommended.
The Huawei adapter fits better with the TP-Link router due to its shape, making it easier to place on the power strip. Both adapters are 12V and have matching connectors. I’m worried about whether the AC adapter’s higher current rating—0.5 amps in this case—might exceed what the router supports.
The original instructions have been summarized for clarity. Voltage needs to match exactly. Current should be at least the original adapter's rating (1A) or higher. Examples show which combinations work: 12V 1A, 9V 1A is bad, 12V 0.5A is bad, 12V 1A and 12V 2A are good. Even if they appear alike, verify polarity—typically inside is +, outside is -. Check for matching symbols on both adapters; if absent, test with a multimeter by inserting the red probe inside and black outside. If the meter reads 12V, the core is positive; if it shows -12V, the core is negative. Ensure both adapters share the same polarity.
