Just picked up the 10W iPad power adaptor, as can be read it covers charging multiple devices along with the iPad.
Since my Griffith charger died, dead, RIP after 2 years, this Apple branded $30 essential has come in handy.
You also get a thick power extension cord just the MacBook charger that is way more convenient than the short USB cable that comes with the iPad.
Increasing the carbon footprint, one device at a time.
Would be great if paired to a solar or human powered generator.
