I love the Apple iPod charger. Apple call it the iPod charger, but this is the same charger you get with the iPhone.
It supplies 5 volts @ 1 Amp. Just what you want when you need to charge your non-Apple USB devices. Pictured below are the iPhone 4 & BlackBerry 9000 Bold. There’s three cables in the photo. The missing device is the HTC Desire PDA, which I used to take the photo.
And the other thing I like about having one charger? In my travel kit, I can take the one charger with me as a backup to using the laptop as a USB charger.
