external battery pack ▪ March 27

Thanks to Apple’s patent on the MagSafe connectors used in MacBook Airs and Pros, the list of third-party external batteries for MacBooks previously began with Hyper’s HyperJuice/HyperJuice 2 and ended with Lenmar’s ChugPlug — not much of a variety. Apple’s legal department chased Hyper for attaching harvested MagSafe connectors to its batteries, and Lenmar chose a workaround, sending ChugPlug’s power indirectly though an Apple wall adapter. Neither solution was ideal. It took until now for a completely different third solution to appear: BatteryBox ($220) from Gbatteries Energy.

BatteryBox is the first MacBook power option I’ve tested that doesn’t require either MagSafe or an Apple wall adapter to function. Since the developers went out of their way to create something that won’t run afoul of Apple’s legal team, there’s absolutely nothing Mac-like about its brick-like rectangular design. And it’s not cheap, priced between the two HyperJuices and higher than ChugPlug, which can now be had for only $100. But it works, adding a 60-watt-hour additional battery to the 38-95-watt-hour cells already inside MacBook Airs and Pros. So if you’re on the road without access to a power outlet and need to add hours of additional runtime to your Apple laptop, this is a viable alternative….

New startup Q Designs seeks to help solve a problem that many people have: we sometimes need to power our mobile electronic devices, but we don’t want to carry external battery packs or bulky charging cases. Q Designs’ solution, the QBracelet, looks like an ordinary bracelet, but it is actually a high-tech charger that can juice up your electronic device discreetly.

The QBracelet will work with iOS and Android devices at launch. No cord is needed, since inside the bracelet’s clasp there is a lightning adapter for Apple products and a micro-USB port for Android devices.

Most technologies have changed beyond all recognition in the last 10 to 20 years. Compare a smartphone from 10 years ago with the latest iPhone, and the difference is night and day. Laptops, TVs, cameras … pretty much any technology you can name has transformed almost beyond recognition. But there’s one technology whose pace of development seems truly glacial: batteries.

I’m not suggesting battery tech hasn’t improved at all, of course, but my smartphone 10 years ago got me through a typical day with a bit to spare, and my iPhone today does pretty much the same (albeit in a significantly smaller package). Those tiny fuel-cell batteries they keep promising us, with smartphone and laptop battery-life measured in weeks and not hours, seem as elusive as ever. Until that glorious day arrives, there will be times when our iPhone or iPad just isn’t going to have enough power to cope with an extra-long day, weekend camping trip, or similar.

There are a couple of different approaches to the problem. The first is a powered case. We previously reviewed the Morphies Juice and Air power sleeves. This is ideal when you know in advance that you’ll need the extra power and don’t mind a bit of extra bulk to achieve it. The second approach is an external battery pack you use to recharge your phone (and other USB-interfaced gadgets) when needed, or when you’re in one location for a while.

This is the approach taken by the Digital Treasures Powerflask, a cute-looking pack that can simultaneously charge an iPad and either one or two iPhones … expand full story
