Replacement Power Supply

The ABLEGRID AC adapter delivers DC power to the Linksys CG7500 AC1900 dual-band modem router. It accepts worldwide AC input from 100 to 240 volts at 50 to 60 Hz. The unit includes a barrel-tip connector and a detachable power cable. Over-voltage and over-heat protection circuits guard the connected equipment.

Ideal for Lost or Damaged Originals

Owners of the CG7500 router who need a direct replacement will find this non-OEM unit matches the required output and tip size. Buyers whose devices require a different voltage, polarity or connector diameter should look elsewhere. The adapter is designed solely for this specific router model and is not suited for other networking hardware.

Critical Specification — Barrel Tip Dimensions

Compatibility hinges on the connector tip matching the router's power jack exactly. The product data notes the tip style but does not publish the inner and outer diameter measurements. Verify the dimensions against the original supply before ordering to avoid a mismatch.

Questions about this item

How do I install this AC adapter for the Linksys CG7500, and what step do people often get wrong?

Plug the barrel tip into the router's DC jack, connect the supplied power cable to the adapter, then plug into a 100-240V AC outlet. The common error is not verifying the tip size and output polarity match the router before powering on.

What maintenance or replacement will this charger need over time?

Keep the adapter in a well-ventilated area away from heat sources and soft surfaces. No user-serviceable parts exist; replace the unit if the cable frays, the barrel tip loosens, or the over-voltage or over-heat protection triggers repeatedly.

What limit appears first when this adapter runs continuously under load?

The over-heat protection circuit activates first during sustained high-current draw, especially if airflow is restricted. The adapter accepts 50-60Hz input worldwide, but thermal limits determine continuous output duration.
