A:Answer Hi David! Yes, you should be able to charge it through a regular USB port or any USB AC wall adapter. As for Non-USB AC Power adapters, we recommend using 5 volt chargers. It takes up to 2 hours to fully charge your headphones. The LED turns off once charging is complete. TIP To check the battery status, press the power button towards the Bluetooth button while wearing
your headphones and not on a call. If you have further questions, feel free to contact our Customer Care Team at: 855-765-7878.
