Last year you got them an iPad for Christmas—they sure were lucky. But how about giving them the power of even more go-anywhere convenience with a solar iPad case?

A growing number of companies offer cases that double as chargers for your minicomputer. They’re a great compliment to a great device, and designs like LilyPad’s case are pretty sleek and attractive.

Just about anyone would be stoked to see it or Voltaic System’s Spark Tablet case under the Christmas tree—unless of course they don’t have an iPad or tablet to go with it.

If you’re considering one, hurry up. These things are in limited supply, and they aren’t necessarily cheap. Spark’s case is $299, but it has an advanced battery and can charge multiple devices.
