ECS Stackport is a 3 parts computing system interlinked through wifi, bluetooth and wireless charging technology. Each module, miniPC, bluetooth speaker, and wireless HDD, has one built-in battery which can provide the power needed for normal operation and act as a power supply for cellphone with wireless charging supportability. It can function on its own and stack in different positions and orientations. The design also supports future function upgradability. With this vision, end users will be able to create their ultimate Stackport.
