While thumb-typing or finger-swiping on your smartphone screen may be good enough for tweeting or texting, more wordy activities -- like typing long email messages, taking notes at conference sessions or writing documents like this one -- are grueling at best.

For that, you need a physical keyboard. Universal Foldable Keyboard is the perfect travel companion—its ultra-thin, lightweight, compact design lets you easily take it wherever you go so you can get more done on your tablet or smartphone no matter where you are.

Features :

• LIGHTWEIGHT and POWERFUL - Ultra Lightweight and extremely durable. This device is designed to withstand heavy daily use and occasional falls. 
• COMPATIBLE with MOST MODERN DEVICES - The high compatibility of this keyboard enables users to connect it with almost any device via bluetooth. Almost all Windows/Android/iOS Smartphones, Tablets, Desktops and Laptops are compatible with our Universal Foldable Keyboard. Note: Touchpad is currently not supported on iOS devices.
• GREAT for VACATIONS and TRAVEL - Work on the go with this compact bluetooth keyboard and a smartphone or tablet. No need to carry heavy bulky laptops.
• RECHARGEABLE BATTERY - Up to 48 hours of typing with only one charge. The Wireless Folding Bluetooth Keyboard has a rechargeable lithium-ion battery. Standby time is up to 560 hours.
• INCREASES PRODUCTIVITY - This wireless mini Bluetooth keyboard permits users to instantly flip their tablet or phone into a tiny laptop computer for fast, comfortable typing. Touch screenwriting is terribly slow as compared to using an old-school keyboard. This could be a lifesaver if you text or email using your phone often.
