Данный адаптер не выдает заявленную мощность (вот хороший адаптер), а преимущество его в том, что он не заклеен и легко разбирается. Внутри установлена плата, которую можно вынуть и заменить на свою, либо просто усовершенствовать оригинальную - подогнать под свои нужды.
Интерес данный адаптер представляет для тех, кто собирается его модифицировать или использовать его корпус для свои разработок.
