Plugable Compact Bluetooth Folding Keyboard and Case for Android, iOS, Windows


The best possible Bluetooth keyboard would be one that’s compatible – a standard Bluetooth keyboard that also supports the special keys and codes of Windows, iOS, and Android systems. It would be portable so you could fold it down to the size of your phone and throw it in your bag. And it would be durable so you can take it on the road and not worry.

The Plugable Keyboard is elegantly engineered to strike a balance between these competing demands:

  • The back and sides are strong but lightweight aluminum. The hinges are stainless steel. This makes it extremely durable
  • The hinges are extremely smooth, it’s a pleasure opening and closing the keyboard
  • It comes with a soft but strong case that both protects the keyboard and anything else you’d throw in a bag with it
  • The case transforms into stand for your phone or tablet and adjusts to any angle
  • The keyboard has special support for Android, Windows, and iOS keymappings
  • It has a USB-charged battery that lasts for weeks of normal use


The keyboard has two wings that fold out from the center on stainless-steel hinges, offering a large area for typing. Strategically-placed magnets at the joints and edges secure the wings when the keyboard is both opened and closed.

During use, the keyboard is surrounded on three sides by solid aluminum. When folded, the backs of the wings cover the top, providing durable metal protection on all sides. The delicate innerworkings are further protected by plastic covers over the hinges.

The keys have a crisp and familiar touch, with the same scissors-type mechanism found on most full-size keyboards. They are the same size as a typical laptop keyboard, but pitched about 1/32 inch closer. This allows accurate touch-typing for most people. However, those with large hands may find the keyboard somewhat cramped, as with most portable keyboards.

No space is wasted. The upper row of keys combines a normal set of number/symbol keys with functions keys that provide shortcuts to many functions in Android and iOS devices, while working as keys f1-f12 in Windows. These keys are made smaller to allow more room for the main QWERTY keys, while maintaining portability.

The fitted case is lined with soft microfiber on the inside to protect the keyboard, while a soft leather-like surface on the outside prevents marring of your phone and other items during transport. A quick flip of the cover turns it into an adjustable stand for your phone or tablet (see folding instructions below).

Q: Does the keyboard lock in the open position so that you can use it on your lap?
A: It locks magnetically in the open position, but the magnets are not strong enough to securely keep the keyboard open when typing on your lap.

Q: Does the keyboard require an authentication code during pairing?
A: No. You are not required to enter an authentication code during pairing. Instead, once a phone, tablet, or computer has connected to the keyboard and automatically paired with it in Windows, Android, or iOS, the keyboard won’t connect to any other systems until you tell it to forget the current pairing. This is accomplished by pressing the Fn-Bluetooth key, which is the only way to put the keyboard in discoverable mode and make it visible to other devices that are in range. You can always tell when the keyboard is in this mode, because the blue light at the left-center will flash. This causes the keyboard to forget its prior pairing and be available for others to connect.
