Replacement Charger for Sony WH-CH400 and WH-CH500

This ABLEGRID AC adapter is a non-OEM power supply built for the Sony WH-CH400 and WH-CH500 wireless on-ear headphones. It accepts a worldwide AC input of 100-240 V at 50-60 Hz and delivers DC output through a tip size shown in the product images. The unit carries CE, FCC and RoHS certifications and includes over-voltage and over-heat protection.

Suitable for owners needing a spare

Buyers who want an original Sony-branded adapter should look elsewhere, as this is a third-party accessory. Users who cannot confirm the exact DC output voltage and connector tip dimensions from the reference pictures should not purchase this item, since compatibility depends on those specifics matching the headphone requirements.

Designed for continuous operation

The charger incorporates over-voltage and over-heat safeguards intended to maintain stable performance during extended charging sessions. The supplier advises keeping the adapter in a well-ventilated area with suitable humidity when used for long periods and avoiding placement on skin-contact surfaces to prevent heat build-up.

Questions about this item

Does the charger work with a standard UK 240 V mains socket?

Yes, the input range covers AC 100-240 V at 50-60 Hz, so it accepts 240 V UK mains without a voltage converter.

Will this adapter charge my older Sony WH-CH400 headphones as well as the WH-CH500?

The charger is listed for both WH-CH400 and WH-CH500 models, so it will power either headset.

How can I confirm the charger is delivering power correctly after I plug it in?

Check that the headphone charging indicator lights while connected; the adapter includes over-voltage and over-heat protection for safe operation.
