OtterBox reveals a portable and stackable wireless charging system
OtterBox has a solution to limited battery life. Today, the company revealed OtterSpot, its Qi wireless charging power bank, and stackable batteries. The OtterSpot Charging Base looks a bit like a thin hockey puck. It's designed to be stackable, meaning you can pile up to three puck-like OtterBox Wireless Charging Batteries and a device on top of it and charge all of them simultaneously. Each battery can then power any Qi-enabled device and support wired charging via a USB-C port. The battery packs come with 5,000 mAh of capacity and up to 10-watt wireless charging speeds.
Exogear's Exovolt Plus 'stackable' battery pack claims to be the first of its kind
We've seen (and tested) a fair share of interesting power packs during our time, and Exogear's hoping to make a mark of its own in this very juicy department with what the outfit's calling "the world's first" stackable battery pack. The newly minted Exovolt Plus consists of a main 5,200 mAh kit, which can then be paired -- or, in this particular case, stacked -- alongside a "Sub Battery" unit to create the ultimate portable charging station. One thing worth noting, though, is that each extra stack will be sold separately for nearly $50, while the essential Exovolt Plus is set to run at about $90 minus some change. Given its universal capabilities (30-pin, USB and micro-USB), something tells us the Exovolt Plus won't have trouble landing any suitors despite its somewhat hefty price tag. Still, you'll have to wait a little while before you can snag one of these, as it's currently listed as "coming soon," and its creator's yet to reveal when we can expect it to go on sale.
MIT's folding CityCar takes a spin on video, still no room for humans
The MIT Media Lab has been working on a folding, stackable electric vehicle for quite a few years now, but it seems those have at least been fairly productive years, as the so-called CityCar has now finally progressed to something resembling a finished prototype. The only problem for those eager to hop into one is that it's a half-sized prototype, which makes accommodating a driver just a tad difficult. It does do a fairly good job of folding itself up though, and MIT expects a full-size version to go into production in 2013. Interestingly, MIT doesn't necessarily see people actually owning the vehicles themselves, but it would like to see them be made available throughout cities -- letting you rent one for a short trip across town, for instance, and not have to worry about returning it. Head on past the break to see it on video courtesy of The Next Web.
MIT developing carbon-free, stackable rental cars
Sure, we know you love actually owning a car, but let's be honest -- in large cities with condensed layouts, your H3 doesn't make a lot of sense. A group of researchers at MIT have been hard at work developing a solution that's kind on the planet and your scrawny legs. A team called Smart Cities have designed a small, two-seat, electric vehicle -- which they call the City Car -- that can be "stacked" in convenient locations (say, just outside a subway stop), and then taken on short trips around urban areas. The cars -- which are based around an omnidirectional "robot wheel" that encases an electric motor, suspension, and steering -- can be "folded" and attached to a group of other cars for charging. The lineups of rentable vehicles would be accessible from various points around a city, with six or eight cars occupying just a single "regular" car space. Of course, you'll have to forgo your 24-inch rims... but that's life.[Via Technology Review]
