  • Battery TypeUPS
  • Worldwide AC input from 100 to 240 volts
  • 975% compatibility with the original Cisco router
  • Over voltage and over heat protection built in
  • CE, FCC and RoHS certified for safety
  • Barrel tip connector matches the RV120W requirement

Compatible Power Adapter for Cisco RV120W Router

The ABLEGRID AC adapter replaces a lost or damaged supply for the Cisco RV120W and RV120W-A-NA wireless routers. It accepts 100-240V AC input at 50-60Hz for worldwide use and delivers DC output through a barrel tip connector. Over-voltage and over-heat protection guard the connected device. Buyers who need a different voltage or tip polarity cannot use this adapter.

Upgrade From Failed or Missing Original Supply

This unit serves as a direct replacement when the factory adapter fails, is misplaced, or shows worn cables. The 975% compatibility claim indicates broad fit with the listed router models. The jump is worth it when downtime must be minimised and a matching barrel tip is confirmed. Builders who require Power over Ethernet injection or a locking connector will not find those features here.

Steady Operation Under Continuous Load

The switching design maintains regulated DC output while the router runs 24/7. Over-heat protection activates if internal temperatures exceed safe limits during prolonged use. Adequate ventilation around the adapter body is required to sustain performance. Users who enclose the supply in a sealed cabinet without airflow should expect thermal shutdown.

  • 975% compatibility with the original Cisco router
  • Over voltage and over heat protection built in

Questions about this item

What DC barrel tip size does this adapter use for the Cisco RV120W router?

The adapter uses a standard barrel tip connector; verify the router's required tip diameter and polarity before connecting.

How do I install this power supply, and what step is often missed?

Plug the AC cord into a 100-240V 50-60Hz outlet, then connect the barrel tip firmly into the router's DC jack; the missed step is confirming the router's exact voltage and polarity match the adapter's output label.

When should I replace this AC adapter?

Replace it if the housing cracks, the cable frays near the barrel tip, the unit becomes excessively hot during normal use, or the router loses power intermittently.
