Apple’s much-anticipated iWatch could use solar power and wireless charging technology to prolong battery life and make juicing up as painless as possible, according to sources familiar with the company’s plans who have been speaking to The New York Times.

One of the biggest challenges Apple faces in perfecting its smartwatch is ensuring it offers enough power to get us through the day. Its goal, according to earlier reports, is to provide at least four to five days of use before a charge is needed, but that’s no easy feat for a device that must be small enough to wear on your wrist.

Unofficial iDevice chargers have taken the form of everything from the hand crank to to the camp stove, and now it seems that Apple is getting in on the act too by taking out a patent for portable solar panel chargers. The patent application — filed with the US Patents & Trademark Office — details a power management system incorporating a solar panel accessory, compatible with both Macs and iDevices, and potentially attached by way of a USB connection. By turning solar energy into electricity, this could then be used to charge future iPhones or MacBooks without the need for a mains power charger.

You might – as I did – laugh at the idea of a solar-powered keyboard for the iPad. And then you will remember that independence from power supplies is one of the iPad’s main features. And then you will take a closer look at this aluminum and plastic slab and see that it looks a lot like my favorite iPad keyboard from Zagg.

You know how camping is all about roughing it and rusticity? Forget it. Goal Zero teamed up with Eddie Bauer to design a solar-powered tent.

Some cases bring battery backup with them, others are waterproof. One or two allow you to charge your iPhone with energy from the sun.

The Snow Lizard SLXtreme iPhone 4 case does all three, and now it’s coming to the iPhone 5 and iPad.

If you’ve been looking for a stylish smartphone or tablet charger with sustainable economic benefits to boot, then this Cult of Mac Deals offer is going to be a sight for sore eyes.

Waka Waka POWER’s patented chip technology allows for solar charging that is 200% more efficient than most competitors. Rock-solid durability and the capability to charge via USB (smartphones, tablets, bluetooth devices, and everything else that charges via USB), solar, or AC guarantees you’ll never be without power again. And Cult of Mac Deals has it for only $59.99 for a limited time.

I play the street life
Because there’s no place I can go
Street life
It’s the only life I know
Street life
And there’s a thousand cards to play
Street life
Until you play your life away

So go the lyrics to Randy Crawford’s fantastic Street Life, which is not — as far as I know — the official song of AT&T and Goal Zero’s new “collabo” Street Charge.

Street Charge is a new scheme which will see AT&T deploying solar charging stations throughout New York City.

Believe it or not, Christmas is almost here, and we’ll mark this midwinter festival by getting together with friends and family and continuing to drink and eat far too much.
Meanwhile, we also buy gifts for those same friends and family members, whether they want them or not. Luckily, we’re here to help, and if you follow our festive advice, your gifts just might make it into the “wanted” category.

From now until Christmas, Cult of Mac will be putting together holiday gift guys full of ideas for the special ones in your life, no matter what their interests or your budget. Today, we’re looking at gifts that cost less than $100, for people you like quite a lot, but not that much.

It’s August, which means two things. One, there’s no news to report on, which means that most of a gadget blogger’s workday is taken up with siestas and refreshing beverages. And two, it’s vacation time! That’s right: The whole northern hemisphere likes to take a break at exactly the same time, all the better to enjoy congested roads, overpriced plane tickets and overcrowded hotels.

To ease your pain, we’ve put together a list of the best travel gadgets. You may not enjoy spending a hot and stuffy month with your in-laws, but at least your tech won’t let you down.

I spent most of last week riding my loaded-up bike through the north of Spain, and as any self-respecting geek would do, I was carrying gadgets, including a power-hungry iPad 3, and a Changers solar-powered charger. I’m planning a longer post on how this worked out, but right now I’m going to tell you about a new accessory for the Changers charger which should make it even more effective on road trips.
