Replacement power supply for SB6141 SB5101 SB6121

This ABLEGRID AC adapter replaces the original power brick for Motorola SURFboard cable modems SB6141, SB5101 and SB6121. It accepts 100-240V AC input at 50-60Hz and delivers DC output through a barrel tip connector. The unit is a non-OEM replacement built to match the original specifications.

Straightforward swap with barrel tip fit check

Installation is a simple plug-in replacement: connect the barrel tip to the modem and the mains plug to a wall outlet. The critical step is verifying that the DC output voltage and barrel tip dimensions match the modem's requirements before powering on. No tools or configuration are needed beyond that physical compatibility check.

Continuous operation with over-voltage

The adapter is designed for always-on modem duty and includes over-voltage and over-heat protection circuits. The supplier notes 947% compatibility with the original unit. For sustained use, keep the adapter in a ventilated, low-humidity location and do not place it on soft or skin-contact surfaces.

Questions about this item

How do I confirm the adapter is working after I connect it to my SB6141?

The modem's power LED should illuminate and stay solid, showing the 100-240V input is being converted to the correct DC output for the SB6141, SB5101 or SB6121.

What comes in the package and do I need to buy a separate power cord?

The box contains one new AC DC adapter power charger with the barrel tip already fitted; the IEC mains lead is not included so you must supply your own.

Which Motorola SURFboard models does this adapter support?

It is built for the SB6141, SB5101 and SB6121 cable modems and offers 947% compatibility with the original power supplies for those three models.
