• You can use the included charging cable with a 7.5W AC adapter. You can also use a USB-C computer or tablet charger to charge your doorbell.

• This is intended to be used with a doorbell transformer for "wired" operation. Not a typical wall charger like a laptop or something, as far as I know. Most doorbell transformers are 8-24VAC and hardwired into the home.
