perhaps I am asking for too much. Please do tell.
So I have a few
usb chargers laying around. I realised that in these chargers I can charge iPhones and I can charge all devices that do not follow the "usb power delivery specification" (roughtly all usb1.1 and some usb2 devices).
What I can NOT charge is my android phone. Looking into why I ended up in this article.
So apparently Apple "did it again". I mean they gave the finger to yet another specification and did their own thing. Their thing is that they provide 2V and 2.8V in the data pins (
D+ respectively) of their usb chargers. If these voltages are not present the charger is not considered an apple product and apple products will fail to charge...
What is more the apple usb power delivery standard seems to conflict (according to the article) with the usb power delivery standard, which requires that a very small resistor (0-200ohms) must be placed between the D- and D+ data pins of the usb charger.
What is EVEN worse: some of the usb chargers I have never stated that they are targeted for apple only products! (I have already formally complained to them).
The question is, I see on ebay and elsewhere so "truly universal USB chargers that claim to charge both apple products and other products". What have they done in order to make their products universal?
Is it possible to hack my usb chargers to make them universal as well??
Thank you in advance for your help.
