Physically, I will admit the apple lightning connector is nicer, it's
still small, is reversible and it inserts smoothly, but I wouldn't want
a proprietary connector.

Funny you should mention the lightning as I have iPads which
I also want to extend, so, I bought these extension cables today:

I haven't opened them, because, when I got home, I realized that
I *maybe* should have gotten USB 3.0 extensions, instead of USB 2.0
extensions?

Assuming the big end is plugged into something of high enough power,
does it matter if the USB extension cable is USB 2.0 or 3.0?

I mean, I understand that 3.0 is more power, but that is for the port,
right? Is it also the cable?

That is, would I lose some power simply by connecting the iPad to the
lightning to the USB 2.0 cable to the 2.1 Amp wall charger ?
