Rather like suave stealthy superheroes, there are devices around which pretend to be that which they’re not. Like, for instance, this lens which is clearly of no use to anyone at all for low light photography.

So, in a similar vein, we are pleased to bring you the Peppermint USB Gadget Charger, which also happens to feature some of the most intelligent design decisions we’ve yet seen in a USB charger.

For one thing, inside the harmless looking minty tin is a full fledged USB port and electronics connected to a standard AA battery box. Which means that once you’ve exhausted the rechargeable batteries while out and about, you can replace them with standard store bought AAs and carry on in an instant. No need for panic or a wall socket.

The spare space can also be used to store adapter cables, in case you need to charge up an iPhone alongside your typical Android smartphone. Genius. All in all, this little tin could be the answer to most power questions out there. And it’s a bargain at just $39.95.
