As a society, we are more connected than ever — our work, correspondence, relationships, and normal everyday activities can all be organized into our mobile devices. Though many of us are free to work and all of us are free to communicate anywhere in the world wirelessly, we are tethered by our batteries. As the charge indicator plummets, we are either frantically scrambling to find an outlet (and sometimes the charger itself) or we’re sitting on a dirty floor checking the percentage every few minutes.
Seattle-based Poros has been designing carry-all products that power your devices on the go, and its first backpack is its latest example of form and function. The Tetra by Poros is built to adapt to a wandering lifestyle, seamlessly charging your phone, tablet, and USB-C laptop.

Poros recently launched an Indiegogo page for the Tetra, where the early birds could get the $215 bag for as low as $100. “Mobile devices … do great things for us, from keeping us connected, to ordering a ride, but the reality is they do have a downside when it comes to their need for charging,” says Poros founder John Borofka. ” … We set out to change this by building a bag from the ground up that meets users’ power needs without having to ever worry about charging, packaged in a stylish bag that users are proud to have on their back.”
The durable Tetra features ballistic nylon construction and all-metal hardware. Despite a slim profile, it has room for your laptop (a sleeve accommodates laptops up to 15 inches), tablet, and books. You can leave your cables and plugs behind, as the bag comes with fully integrated connectors. Its built-in 10,000mAh lithium polymer battery can deliver from three to six complete smartphone charges at a rate of 2.1 amps.
The Tetra supports the latest USB-C connections, which can be found in the new MacBook and Chromebook Pixel. It effectively doubles the battery life of the MacBook. Charging is activated with a touch of a button. A full LED display indicates battery status and charge rate.
The Tetra weighs just half a pound, and can charge two devices at once. The first connection is a standard USB-type, and for the second you can choose between an Apple Lightning or Micro USB. All Poros bags are TSA approved for carry-on and checked luggage.
The Tetra is expected to ship in March 2016. For more information, visit the Poros official site.
Merely days after the iPhone Duo hit the shelves, images of broken screens on the phone started popping up across social media. Until now, it’s been unclear what’s causing the line of defective pixels that appears vertically along the crease, as well as horizontally, on the phone’s inner display.
Apple has finally acknowledged the issue, which has shown up on iPhone Duo units owned by customers as well as demo units in stores. In a statement shared with Bloomberg, Apple says that not all iPhone Duo units are affected and that those that are tend to show the display fault early on. The company added that users who experience problems with their iPhone Duo display should contact AppleCare for a replacement.
Not long ago, Apple treated independent repair like an act of outright hostility. The Cupertino giant locked down parts with serial-number pairing, while repair tools remained firmly out of reach of anyone outside its authorized repair network. More importantly, the company waged a legal and lobbying battle against right-to-repair legislation.
I've covered enough of these fights over the years to know what a shift looks like. That's why what happened in October 2026 genuinely caught me off guard. The day the iPhone Duo went on sale, what may be the most mechanically complex iPhone to date, Apple pulled off a surprising about-face. It published teardown-style repair manuals for a handful of major components.
Apple's first foldable phone is now on shelves, in short supply, but with an unreal amount of buzz around it. After all, it's the first foldable iPhone, and there's plenty that this phone gets right. But there's also a lot that is either broken or underwhelming. What's peculiar is the dialogue around this phone, and how it has completely overshadowed every other attempt at making a phone with a similar form factor.
I've spent some time with the iPhone Duo, and I've used the Galaxy Z Fold 8 for almost three months now. In my opinion, Samsung deserves more credit. When the Galaxy Z Fold 8 arrived earlier this year, it was celebrated in some circles and ridiculed in others for supposedly copying what Apple would eventually deliver with the iPhone Duo. The dialogue was pretty odd, for multiple reasons. Samsung has been making foldable phones for years, so claiming that it copied a product Apple hadn't even launched was simply absurd.
