A new pico projector is coming to the market from Sanwa and it is designed to specifically work with the Apple iPhone.

The 400-PRJ011 is compatible with the iPhone 4 and the 4S and it slides around the phone to improve portability.

Not only this, but the battery pack on the projector, which has a five hour charge time and can provide 2.5 hours of projection, will also charge the phone when the projector is not in use.

Of course, the most important thing with a projector is its image quality and, being a pico projector, the device is not going to stand up to many larger devices. However, it does provide a 640 x 360 resolution and a 1,000:1 contrast ratio. This allows it to project a screen of up to 65 diagonal inches in size.

While the image quality isn't bad for a small device like this, it is the Sanwa gadget's ability to provide its own power that has got people talking as using it will not be a drain on the phone's own resources and may even provide a much needed boost when the iPhone's own battery is on the blink.
