Made these at work just now. Vinyl stickers to identify which charger is which. I always have both of them thrown in a bag together so I figured this would be a good way to tell what is what from a quick glance. I have a few extra sets, If anyone is interested I will mail them free of charge -while supplies last Just pm me where you want them sent. Anyone else notice the usb end is squared on the iPad charger? Thats the only way I was telling them apart till now.
