12 V power adapter for CM1100

The ABLEGRID 12 V AC adapter is a non-OEM replacement charger built for the Netgear Nighthawk CM1100 DOCSIS 3.1 cable modem. It supplies a DC output through a barrel tip connector and includes over-voltage and over-heat protection. The unit is CE, FCC and RoHS certified and rated for worldwide AC input.

Verify output voltage and tip size

Before ordering, confirm that your modem requires a 12 V DC input and that the barrel tip dimensions match the original connector. The adapter accepts AC 100-240 V at 50-60 Hz, so it works on mains supplies worldwide. Check the label on your existing power supply to ensure the polarity and connector fit are identical.

Thermal and power behaviour

In normal use the adapter runs at the modest 12 V output required by the CM1100, so heat generation is low and the built-in over-heat protection rarely engages. Keep the unit in a ventilated area and avoid placing it on soft or insulating surfaces during extended operation. The wide AC input range handles voltage fluctuations without drawing excessive current.
