Compatible router power supply

This ABLEGRID adapter replaces the original power supply for the Netgear Nighthawk AX4 RAX40 Wi-Fi 6 router. It delivers 12V at 2.5A through a barrel tip connector. The unit accepts worldwide AC input from 100 to 240V at 50 or 60Hz. It is a non-OEM accessory built to match the original specifications.

Thermal behaviour during continuous operation

The adapter includes over-voltage and over-heat protection circuits that activate under sustained load. The supplier advises keeping the unit in a ventilated area and avoiding placement on soft surfaces during extended use. These measures help maintain stable output when the router runs continuously. No active cooling or fan is mentioned in the data.

Deciding specification: 12V 2.5A barrel output

The critical detail is the DC output of 12 volts at 2.5 amps with a barrel tip connector. If your router requires a different voltage, amperage or tip size, this adapter will not work. Verify the original power brick label before ordering. The worldwide input range suits travel but the output must match exactly.

Questions about this item

How much heat does the 12V 2.5A adapter produce when powering the RAX40 router continuously?

The adapter includes over-heat protection and the supplier advises keeping it in a ventilated area during extended use.

What must I already own for this charger to work with my Netgear Nighthawk AX4 RAX40?

You need the router itself; the adapter supplies 12V 2.5A DC via a barrel tip that matches the RAX40 power input.

Will this power supply run reliably alongside an older Netgear router on the same power strip?

Yes, the 100-240V AC input and 50-60Hz frequency match standard mains, so it shares a strip with legacy gear without issues.
