MacBook as a battery pack for iPod/iPhone


The day before my trip to China, I went to Future Shop and bought a battery pack for my iPod Touch.  I only realized when I got home that it was the type that blocked the headphone jack.  Back to Future Shop I went.  My worry turned to despair as I discovered they didn’t have any battery packs compatible with an iPod Touch.  How was I supposed to survive the 10 hour flight!?  I certainly couldn’t depend on the China Air in-flight entertainment.  And the book I was reading wasn’t going to last either.

On the way home, I had a eureka moment.  I could just plug my iPod into my MacBook.  My MacBook doesn’t last very long when playing video on its screen, but I could just plug in my iPod and play the video on that.  Maybe I could even put my MacBook to sleep to increase the battery life.  It turns out you can.

For maximum battery life:

  1. Fire up your MacBook (any laptop should work)
  2. Plug in your iPod via USB
  3. Close the lid on your MacBook to put it to sleep
  4. Voila! Your iPod should still be charging

Add a cheap audio splitter and you’ve got entertainment for two.

I’m sure I’m not the first to think of this, but I couldn’t find anything like it after a quick search, so I figured it’s worth sharing.  Let me know if it works for you.
