One thing most people aren’t covering, unless it has a motor that spins in it, chances are your device is modifying the AC in your walls to be DC at the device. Most products have discrete power supplies built into the device itself, or in the case of USB chargers and wall warts, they convert the power right at the outlet.
Fun fact, some low quality power inverters can produce an annoying hum.
