Works with any Bluetooth device.
The black Anker ultra-slim Bluetooth keyboard is down to $12.99 with code ABCD7111 on Amazon. The keyboard normally sells for around $20 without the code and this is one of the best prices we've seen in the last year. You can also get the White version down to the same price with code ABCD7121.
These are wireless keyboards designed to be ultra compact and take up a lot less space than traditional keyboards. That makes them great for use with Bluetooth mobile devices, like the iPad or your smartphone. They have a power-saving mode that helps them last up to three months, which means you don't have to worry too much about keeping them powered up when you're on the go. There is space for two AA batteries. They are compatible with iOS, Android, Mac, and Windows. Anker backs them up with an 18-month warranty. Users give the white version 4.2 stars based on more than 3,300 reviews.
