I want to know the answer to the following question:
What does the USB Battery Charging Specification Revision 1.2 make clear of?
All the background I'm provided with is that "The USB Battery Charging Specification Revision 1.2 (released in 2010) makes clear that there are safety limits to the rated current at 5 A coming from USB 2.0.". Is that enough to answer the question?
Answer: yes
