Wearable tech is proving a difficult thing to pigeonhole, but perhaps that's because we're over thinking it. Take the XOO Belt, for example. It's tech, because it's a USB phone charger, and it's wearable, because it holds your trousers up.
So by definition, it's wearable tech. But a smart belt? Hmm...
Strap on a charger
This new device has just taken to IndieGoGo in an effort to crowdfund production of the world's first belt-based portable charger.
Surprisingly the rechargeable battery isn't just found in the buckle, which would make it quite a bulky beast that'd draw unnecessary attention to your trouser area. It's actually a new type of flexible lithium ceramic polymer battery that reaches all the way around your waist, delivering 1300mAh of USB power.
Coupled with the 800mAh battery that is housed in the detachable polished zinc buckle, and you've got 2100mAh of power boost for your smartphone about your person, whenever you need it.
Rather cleverly, there's a USB cable magnetically stored behind the strap, just long enough to allow you to connect your phone inside your pocket, so charging occurs within the safety of your trousers, jeans, trakkie bottoms or bermuda shorts.
With almost $38,000 of its $50,000 goal already in the bag, and 25 days left to go, the XOO Belt looks likely to be a crowdfunded winner.
