Compatible Models

This AC adapter is built for Comcast Xfinity Motorola SB6121, SB6141 and SB6180 cable modems. It replaces the original power supply with a non-OEM unit that matches the required DC output and barrel tip size. Buyers who need a different voltage or connector type cannot use this adapter.

Sustained Operation

The adapter accepts worldwide AC input from 100 to 240 volts at 50 to 60 hertz and delivers stable DC power to the modem. Over-voltage and over-heat protection circuits activate during prolonged use to prevent damage. Units operated continuously without adequate ventilation may trigger thermal safeguards.

Input Limits

Operation is limited to the stated AC voltage and frequency ranges; the adapter cannot be used on DC mains or outside the 100-240 V window. The fixed barrel tip prevents connection to devices with a different plug geometry. Users requiring a higher current rating or a different tip must select another power supply.

How warm does the ABLEGRID adapter get when it powers a Motorola SB6180 continuously?

Will the barrel tip fit the DC jack on my older SB6121 unit?
