Solar Charger for travelers

This solar charger looks like moto W200 cell phone.There are 2 solar panels being build in the leaf of the charge.They use a internal battery to restore the energy from sun.You can turn the  leaf around.This solar charger is very powerful.It requires 7 hour's to charge in a sunny day and they they can give a mobile phone 70 hours of standby time.You can also use this device to charge digital camera,mp4 and portable dvd player.This device is retailed for $79.95.Sounds pricy to me.
