He's talking about using a dedicated charging port instead of using the USB port for charging. 10.5 watts (2.1 amps) at 5 volts probably wouldn't be enough to support usage while charging for the larger tablets.
That's how programming started for a lot of us. Start playing with transistors, then discover 555s, 741s and discrete logic. Eventually discover micro controllers and start coding in assembly and the C. 10 years down, find yourself managing a large team of developers and you absolutely hate it :)
And so you start using your programming skills to travel the world while working, see some amazing places, but discover to your dismay that things aren't any better no matter where you go.
But you continue writing your own stuff, releasing open source programs here and there, and then somewhere along the way you move into freelancing, which removes the protective layer between you and unreasonable customers.
Tiring of that, you move into iPhone apps and discover that you suck at marketing.
And then one day you find yourself living in San Francisco, founding a startup with a bunch of awesome partners, working insane hours, and having a BLAST trying to solve hard problems.
There is much joy and wonder in this world; you just need to look harder.
I have my doubts about the quality of computer education imparted by the likes of NIIT. Years ago, one of my non technical friends wanted to join a C/C++ course at one of their centers. Their claim was they'd teach him both in 6 months, part time. I tagged along with him on the first day and was generally trolling around, asking their faculty if they teach Assembly language. As expected, not one of them had heard of it. One of the more ludicrous responses was something like "What's assembly, is it something like pseudo-code ?".
The parked domain advertising market is so lucrative that even Google has entered it (possibly through the DoubleClick acquisition) with their AdSense for Domains program.
Online banking based payments work just fine for local Indian sites, but I haven't found a way to pay US based businesses without a credit card. The only use I've had for using a credit card has been to pay for AWS and Linode.
