Everyone knew the iPad Air 2’s marquee features — a thinner, lighter body, Touch ID, a gold color option and much faster A8X processor — but fewer people realized that Apple also made subtle changes to the new tablet’s screen, not only improving its visibility outdoors but also changing the way it registered touch input. All of the tweaks added up to a noticeably better user experience, but one category of accessories unexpectedly wound up broken: digital styluses. As it turns out, fine-tipped styluses use tiny electrical pulses to trick touchscreens into thinking they’re fingers, and the pulses needed to be recalibrated to work reliably with the iPad Air 2’s new screen. Adonit was the first to release an iPad Air 2-compatible digital stylus, the $75 Jot Script 2 (reviewed here), and now there’s a second, more affordable option.

Lynktec is one of several stylus makers that have sought a middle ground between expensive $80-$100 Bluetooth styluses and entry-level $20-$30 styluses that lack electronic hardware. The second-generation Rechargeable Apex Stylus ($60) is, like its predecessor, a mostly silver pen with a battery inside and a shirt clip on its edge. It loses the plasticky black top and bottom in favor of a more thoroughly metallic appearance, retaining five rubber finger grips near its tip for comfort. And while it keeps the 2mm polymer writing tip of the original Rechargeable Apex, it’s now backed by electronic circuitry that works properly with the iPad Air 2, as well as all earlier iPads and iPhones…

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). We know battery life remains the same with the 70 percent larger battery going mostly toward powering the new Retina display, A5x chip, and LTE-capabilities, but we wondered last week whether the new battery could take up to 70 percent longer to charge. MG Siegler confirmed in his review on TechCrunch that charging the new iPad takes “several hours” longer compared to earlier generations:

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.
