This is a handy, lightweight accessory & is the perfect compliment for any iPhone 4/4S. Record video/picture content to your device, then immediately play it back with the A100 at up to 60" for up to 3 hours & enhance the sound with the 2W inbuilt loudspeaker. You could even use it to share the latest music videos, online TV or even your business presentation right from your pocket! Alternatively, extend your phone 4/4S/ iPod Touch's ordinary battery life for an added 1.5 hours of use so that you never run out of battery power again. All of this straight from your phone, made possible by Pico Genie.
