Doesn't this suggest all cables are not the same?
I was recently reading about the faster charging spec for iPad 2 and Nook Color, and it seems to require a proper cable? Some Android phones differentiate between slower USB standard 500 mA charging vs AC fast charging.

"Modern" USB cables are the same. A "charger" will short the data pins, which allows more than 500mA of current to be transmitted, but this is typically done at the charger, not the USB side.
What broke? The USB cable? The transformer?
A "charger" is typically just a 5v transformer, a plug and a USB port. Output current varies you want something capable of outputting 700mA to 1A. 500 mA is the standard computer USB port output.
If buying a wall --> USB adapter, you can get anything, just double check the output current rating. If it doesn't specify the output current, DO NOT BUY. My parents ended up with a 250ma "charger" that doesn't charge anything because the output current is too low.
There are tons of "genuine" (not really genuine) Samsung / RIM / HTC USB chargers on Amazon for like $5 with free shipping if you have other things to buy to total $25. Any (that have the desired output current rating) will work. I use my wife's old Blackberry charger at home and the samsung charger that came with my phone at work.
