Replacement power for BT-09 headphones

This ABLEGRID AC adapter supplies DC power to BT-09 wireless stereo headphones. It accepts 100-240 V AC at 50-60 Hz for worldwide use. The unit includes over-voltage and over-heat protection. It is a non-OEM charger built to 115% compatibility with the original specification.

Upgrade from a lost or damaged original charger

The adapter replaces the factory supply when the original is missing or no longer delivers reliable power. The jump is worth it when the tip size and DC output match the headset exactly. Buyers who need a different voltage or connector type cannot use this model.

Steady output during extended listening sessions

Continuous operation is supported by the built-in protection circuits that guard against voltage spikes and thermal stress. Keeping the adapter in a ventilated area helps maintain stable output over long periods. The unit is not intended for use on heat-trapping surfaces.
