I'm always skeptical about crowd funding backed accessories. I have purchased a few winners, but I've also been burned. WonderCube looks like it could be a winner. The WonderCube is a tiny 1 cubic inch accessory that fits on your keychain, but offers 7 different essential functions.
The WonderCube can charge your phone, sync files from your computer to your phone, act as a stand for your phone, be a backup battery charger with a 9-volt battery, read flash memory cards, and even provide a flashlight. It sounds crazy, but it looks great.
The best way to get a feel for this accessory is to watch the video above. I can't believe I'm saying this, but this might be one crowd funding accessory to back. Check out the source link below for more.
