Members of the EU will take a vote to decide if it will enforce a universal charging connector for all smartphones and similar smaller electronics. Certain arguments in favour of this move cite the reduction of e-waste as one of the major advantages to this legislation, while also ensuring easy charging for smartphone users. A similar initiative was introduced in 2014 but was not enforced.

USB Type-C connecting cord The USB Type-C port, popular with many android devices is seen as the likely standard option due to its reversibility of connection, charging speeds and data transfer rates.

It remains to be seen what the future holds regarding this idea from the EU and its degree of practicality in the long run. Source; Source
