comment What is the difference between USB charging and AC charging?
Is there any reference that says they follow the USB.org charger spec? Apple, Sony, and HP do not. Do all HTC phones?

comment Are Android chargers universal in terms of power (Voltage, amperage)?
"Do some chargers try to force 3000 mA down the wire to supercharge their devices?" No, that's not possible. The charger determines the voltage (always 5 V for USB), and the phone determines the amount of current drawn.

comment Why is charging from computer using USB slower than using an outlet?
Shorting pins 2 and 3 together is the official USB charging spec, but not all phones and chargers follow it. Sony and HP and Apple have their own proprietary connections.

comment Why is charging from computer using USB slower than using an outlet?
@ChrisThompson while definitely true for now, the USB org decided to confuse people even further, and added multiple supply voltages to the USB 3.1 spec. Only after lots of confusing negotiation, of course...

comment Why are some USB chargers slower than others?
It's not just "USB charging spec vs Apple spec". There are several other configurations as well. See the datasheet for the ti.com/lit/gpn/tps2511, which tries to interface with all of them, and righto.com/2012/10/a-dozen-usb-chargers-in-lab-apple-is.html, which reverse-engineers several.
