Charge Your iPhone with Sunlight
Posted on August 29, 2010 by vincent oliver
Frostfire created an iPhone case that has a rechargeable lithium-ion battery at the base with a small solar panel embedded on it to extend the battery life of your iPhone 4 while on the go. The Mooncharge battery case, when fully charged, will provide 315 hours on standby or 5 extra hours of talk time. Frostfire doesn’t indicate how long it will take for the battery to fully charge using the solar panel, but they do say that placing the case in the sun for 20 minutes gives about 50 minutes on standby or 5 minutes of talk time.
