As we suspected, new iPad takes longer to charge. Also gets warm inside

While we are waiting for iFixit to tear apart the new iPad so we can get a look at the device’s new 42.5-watt-hour rechargeable lithium-polymer battery, we received confirmation that the battery does take hours longer to charge than the iPad 2 (iPad 2 pictured above).

Mobius rechargeable solar battery case for iPhone available now

Let’s not pretend that Apple isn’t thinking about Solar charging its iOS devices.  It even registered iPodsolar.com in 2007.  Until the solar iPod is released, however, there are other ways to charge your iOS device from the sun.

Etón today announced the availability of their Mobius NSP300B Rechargeable Battery Case for iPhone 4, which was originally announced this year at CES.

The admittedly stylish (for having a solar panel strapped to it, that is) case packs in an 1800 mAh rechargeable lithium ion battery, high-efficiency monocrystal solar panel, and micro USB to charge the battery on cloudy days and nights. Other features include LED charge indicator lights and a stand by switch to turn off direct power transfer. In other words, hitting the stand by switch will let you to collect power without using it, allowing you to control when the case is actually powering your iPhone.

As you can see from the chart below, Etón estimates approximately 1 hour of solar charge will provide you with up to an additional 25 minutes talk time, 20 minutes of data usage (3G), 35 minutes of video playback, or 145 minutes of audio playback. In comparison, a fully charged case will provide you with an additional 5 hours talk time, 8 hours data usage and video playback, and 32 hours audio playback.
