Anker’s New Astro 3 Battery Can Fully Charge an iPad for Just Fifty Bucks

By

anker-astro-3

 

That’s right, $50 nabs you the Anker Astro 3, an external battery with three USB ports and 12,000 mAh, which is — in theory — enough juice to completely charge any iPad.

Why the in theory disclaimer? Because although the Astro 3’s 12,000 mAh capacity exceeds the 11,560 mAh capacity of the battery in the two latest iPads (the iPad 2’s battery is about half that of its successors), there’s always some energy loss when transferring energy from one battery to another.

Alleged iPhone 5S Batteries Pictured On Assembly Line

An image of what is claimed to be a bunch of new batteries for the iPhone 5S on an assembly line has surfaced today. If it is genuine, it confirms the iPhone 5S will be battery-powered like its predecessors, and it debunks rumors that have claimed Apple will turn to more traditional energy means such as coal and paraffin.

Justin Battery Case Powerful Enough To Charge Retina iPad

Despite being so huge and heavy that it’s barely possible for one person to lift, some folks still manage to take the regular-sized iPad out of the house for extended periods of time. And if you’re doing that with the Retina iPad, you’ll know that once the battery has run down you’re looking at three to four weeks to recharge it, even if you were to plug it straight into the high-tension power lines overhead (hint: Do not do this).

That’s why the Justin Ultra-Slim Power Case was invented.

These Days, Even iPhone Backup Batteries Are Fashion Accessories

By

Remember when the iPhone launched, and people complained that the non-removable battery was a “deal-breaker”? And then the very same thing happened to the MacBook in the form of the Air, and the very same people whined the same whine?

Happy days indeed. Now we know better: we can indeed carry spare batteries for our iPhones, only they’re external and don’t require that we power down the phone just to swap them.

And the batteries in our MacBook last way longer thanks to the fact that they are squished into every internal nook and cranny of the computer’s case instead of having to be an easy-to-remove rectangle. Not that anyone ever needed to swap a battery into a computer anyway. Well, except those dullards who would stare at a single Excel spreadsheet for the entire duration of a six-hour plane ride, and they all own PCs anyway.

Which is to say, in a very roundabout way, that Eagle has made available yet another external battery pack. And this one is orange.

Traveling With An iPad And A Camera: Batteries, Backups And Bags [Feature]

By

I just got back from a week-long vacation. We were staying in Tel Aviv, Israel, which meant lots of walking and cycling (I took my Brompton), plus day trips. Which in turn meant traveling light.

The iPad is perfect traveling companion, and the iPad mini is even better. But if you want to take lots of photos with an actual camera, or – worse still – a camera that shoots huge RAW images, you need to plan ahead. And as I didn’t want to take a Mac with me, I needed a few tricks to help out.

This post isn’t about how I managed my photos on the trip (although I will mention that side of things a little in terms of the hardware I used). It’s about the gadgets and apps that help you work around the limitations of the iPad when you’re relying on it away from home.

This is the Unu Enerpak Vault. It’s an excellent spare battery pack for any of your portable devices, and it is even powerful enough to almost (almost) charge the thirsty, thirsty Retina iPad.

Unu’s Ecopak is about as simple as an iPhone battery case can get. And as this also means that it is thin and light, and that it will work with not only the iPhone 5 but any gadget than charges via USB, that simplicity is perhaps its best feature.

The Ecopak consists of two parts. The thin, snap-on shell-style case, and the. Battery pack itself. Let’s take a look.

Apple Introduces New Fast-Charging iPad Power Brick

You gotta love Apple (no, seriously, you gotta love Apple to get a job here at Cult of Mac – Leander tests our faith every day during Morning iService) – it might keep quiet and take its time to fix things, but fix them it does. Well, for high-profile problems at least.

Today’s fix is a new iPad charger, a beefed up 12-watt model which should juice the iPads 3 and 4 faster than the old model.

How Super Algorithms Will Make Future iPhones & iPads Charge Twice As Fast

By

Plug in your iPhone or iPad and charge it up, and you’ll notice that while the first 80% or so will go by pretty fast, they actually kind of suck at charging up that last 20%, taking a lot more time to do so than it feels like they should.

There’s a reason for this. Charging batteries up to “full” is a complicated process. There’s no real way to tell if a battery is completely “full” so all you can do is measure the voltage, which (and this is a vast simplification) tells you how much resistance is being met when you try to put more electricity into the battery.

That’s why it takes so long for an iPhone to charge that last 20%. It charges full blast until it measures a certain voltage, then goes into what’s called “trickle mode” to slowly allow small sips of electricity into the battery until it thinks, based upon some software calculations, that the battery is more or less full. But a new algotihm could make the time it takes to charge your iPhone or iPad go by a lot faster.
