When closed, it measures by 5.75 by 3.5 by 0.75 inches. The iClever Portable Foldable Bluetooth Keyboard measures 10 by 3.5 by 0.3 inches when open. Add impressive battery life, and an affordable $49.99 price, and you have an easy Editors' Choice. It's highly portable, with a unique foldable design that reduces the keyboard to about the size of an iPhone 6 Plus, and it works with devices that run Android, iOS, and Windows. The keyboard itself is a little cramped, but that's to be expected in a peripheral this size, and a sturdy aluminum build and light weight easily make up for it. If you want to type away on your smartphone and/or tablet all day, the iClever IC-BK03 Portable Foldable Bluetooth Keyboard could be for you.
