Yes, it does. You get the USB plug-in with the usual USB lead, which can be used to connect with your computer as well. I've used the USB plug to charge my Kindle with no problem. I also bought a USB plug from Maplins that was sold as universal, which suggests that they're all the same - they must convert the voltage from the mains to the sort of voltage you get from a USB port, and that would be the same for everything that charges from a USB port.
Having said that, you can't rapid charge an iPad from your computer, it takes too much power. Apple say it will trickle-charge, although I'm not convinced! In general you're better off just charging it from the mains.
