Why Is My TRIO ULTRA Making a High-Pitched Noise?Updated 2 months ago

If your TRIO ULTRA charging station is making a shrill or high-pitched sound, here are a few possible reasons:

• Power Adapter Issue: Use the recommended 30W USB-C adapter. Incompatible adapters can cause noise.

• Device Misalignment or Foreign Object: Make sure your device is properly placed and there are no metal objects on the pad.

• Defective Unit: If the noise is loud or constant, even with no device on it, contact us.
