AC Adapter in Proc Filesystem

Alternating current  (AC) adapters  are used to  power or  charge many
common electronic devices, such as mobile phones, laptop computers, or
external  hard  drives.  An  AC  adapter  changes  AC  power  from  an
electrical outlet into the type of power or voltage that an electronic
device needs to work. Typically,  each device has a designated adapter
that is  pre-set to  the proper voltage  conversion. For  this reason,
among others, AC adapters generally are not interchangeable.
