The MultiSync Wireless Keyboard for Mac & iOS from Kanex is a full-sized and low-profile keyboard that can be paired with up to four Windows, Mac, iOS, Apple TV, and Android devices, as well as other smartphones and tablets that are compatible with a wireless Bluetooth 3.0 connection. Once paired, MultiSync Bluetooth keys allow you to toggle between each connected device with one-touch switching. As this keyboard employs Bluetooth technology, it does not require a receiver to be installed on your host system. It operates using a rechargeable 1200mAh lithium-ion battery that can last for up to six months before recharging is required. Once the battery is depleted, it can be recharged using the included micro-USB cable. This keyboard also features a US English layout for Mac and iOS operating systems, a numeric keypad, and hotkeys.
