releted to this question I wonder what the use of the number of
mA printed on an AC-DC adapter/converter means.
I am charging a Bluetooth headset, which came with a AC-DC adapter, over USB using a "DIY-hybrid-cable" and it is working.
The original AC-DC plug (which I've cut) has
450mA printed on it and the USB standard AC-DC plug, to which my "hybrid-cable" is connected, has
1.0A printed on it.
mAnumber has any relevance? Why? I feel I am missing important knowledge.
