Replacement AC Adapter for Casio Keyboards

The ABLEGRID 12V AC/DC adapter supplies power to Casio WK-3100, WK-1500, KT-90G and CPS-80 models. It accepts worldwide AC input from 100 to 240 volts at 50 or 60 hertz. The barrel tip connector matches the original DC input on each instrument. This non-OEM unit is CE, FCC and RoHS certified.

Upgrade From Worn or Lost Original Chargers

It replaces a missing, damaged or unreliable factory supply without changing the voltage or polarity your keyboard expects. The jump is worth it when the original adapter fails, the tip no longer seats firmly or the cable shows exposed conductors. Over-voltage and over-heat protection guard the instrument during extended rehearsals or performances.

Steady Output During Long Sessions

The adapter maintains regulated DC output while the keyboard draws continuous current for layered sounds, rhythms and built-in speakers. Ventilation space around the brick prevents thermal throttling during multi-hour use. Protection circuits engage if internal temperatures rise or input voltage spikes, keeping the supply stable until you power down.

Questions about this item

What barrel-tip connector size does this 12 V adapter use for the Casio WK-3100?

The adapter ships with a barrel-tip connector; verify the tip diameter matches the WK-3100 power jack before ordering.

How do I connect the adapter safely, and what step is often missed?

Plug the AC cord into a 100-240 V, 50-60 Hz outlet, then insert the barrel tip into the keyboard; the step often missed is confirming the DC output polarity matches the Casio unit.

When should I replace this power supply?

Replace it if the housing becomes excessively hot, the cable shows fraying, or the keyboard fails to power on despite a good outlet connection.
