Wall adapters tend to be lower power, ranging from 3 to 36 watts and plug directly into the AC power source. The power source is typically located on a wall or a power strip. Kaga has two basic configurations for wall adapters: fixed AC plugs and interchangeable AC plugs. The fixed AC plug type is country specific, whereas the interchangeable plugs can be changed to fit selected countries. The interchangeable type is usually shipped with the basic body and four plugs: one each for the USA, Europe, UK and Australia.
