This compatibility list is for the v2 of the mintyboost, which uses the LT1302 charger chip but does not have the special iPhoney resistors. Basically, If you got it before August 2010, its definately v2 or earlier

Turns out some devices don't like being charged with a battery pack, usually devices that require special drivers to charge. (Try plugging it into a random computer's USB port, if you need to install software to get it to start charging, you probably won't be successful.) Please post on the forum if you have more information on what works and doesn't! Thanks

Tested Works:

• Apple iPod: Mini, Nano rev 1G/2G/3G, Shuffle 1G/2G, Photo/5G/Video/Classic
  Read Apple's identification guide to see which one you've got, if you're not sure.
• Older Apple iPod Touch (v1), iPhone and iPhone 3G (with v2.0 of the kit) - These do work, but they're finicky. Check the FAQ and try 'Lithium 1.5V' batteries. Unfortunately Apple has made updates to the firmware and hardware to make it harder for people to use "nonauthorized chargers" This has been fixed in v3 of the Mintyboost
