With goals of reducing waste and increasing convenience, European lawmakers have debated whether all smartphones, tablets, and other portable devices should have a standardized charging port such as USB-C.

At least some members of the European Parliament want "binding measures" that ensure one type of charger is compatible with all portable devices, as the European Commission's previous approach of merely "encouraging" tech companies to develop a standardized solution has "fell short of the co-legislators' objectives," according to a briefing on the European Parliament website.

The proposed charging ports for portable devices include Micro-USB, USB-C, and the Lightning connector.

Nearly a year ago, Apple said regulations that would force all smartphones to have the same charging port would "freeze innovation," be "bad for the environment," and be "unnecessarily disruptive for customers."

While some members want the policy to be regulated, forcing companies like Apple to comply, there is still a possibility that it will be implemented with a voluntary approach, which could simply be ignored, according to the European Commission.

European lawmakers have been considering similar regulations since at least 2009.
