I read "charger" to mean "the thing you use for charging", and not really bothering with the technical detail of exactly how this thing is made. I think reading the texts as if they spoke only of the transformer/brick itself is to narrow, and not in line with the common understanding of what a "charger" is. I will offer this suggestion of a precise definition for "charger": the complete technological assemblage requi…
You can define the charger to include the cable, and I can define the phone to include the cable. Either way it doesn’t provide much insight into the definitions with legal force.
The 2018 Comission report has this to say on the subject for example :
The study has, in particular, provided the following information and conclusions: even manufacturers of mobile phones which did not sign up to the Memorandum of Understanding appear to have also adopted Micro-USB charging solutions, leading to the indication that almost 100% of data enabled phones sold in Europe in 2013 were compliant with Micro-USB charging solution.; due to the Memorandum of Understanding, it is estimated to have resulted in six to 21 million fewer standalone chargers over the period 2011 to 2013; the increasing prevalence of Micro-USB charging has limited the need to purchase standalone chargers and consequently reduced the use of raw materials than might otherwise have been the case.
Since the previous experience of the Memorandum of Understanding had proven to be successful for the reasons mentioned above, the Commission wished to continue the approach already followed based on a voluntary agreement. Moreover, a voluntary solution could more readily accommodate new technology and innovation compared to a regulatory option. Additionally, a voluntary approach may have had the advantage of having a wider scope, compared to the regulatory option, for example, it may have covered both ends of the charging cable 79 .
However, given the unsatisfactory outcome so far of the progress in the voluntary option, the Commission will shortly launch a study to assess costs and benefits of different options, including the regulatory one.
