Sanwa is a company that has released an update version of its 'PRJ016 iPhone Micro Projector,' and this revamped version is the go-to iPhone sleeve for any business meeting.
The PRJ016 comes with a 1,850mAh battery that also acts as a charger for your iPhone 4 or 4S, bringing it up to 80% battery life. But the most important feature is its projector that allows you to project movies, pictures and spreadsheets right onto your office or home wall. Projections can last for up to two straight hours on this ingenius device. The PRJ016 requires no added cables or software, simply slide in your iPhone and press the On button located on its side.
The sleeve is so thin that you wont even realize it's also a personal projector.
