What do you even say? Total scam, top to bottom.

Aside from the fact that a device in series with a charger can't do anything, or that smart devices handle their own charging, the "San Francisco" based campaign is written in Chenglish, has unrealistic goals, no verifiable people attached to it, no linked social networks, no actual name....they STILL hit 455% of their initial funding goal with two months left.

TIASBEM!

Aside from the fact that a device in series with a charger can't do anything

Well technically it can, it can signal to the smartphone that it's connected to a high current 1-2A capable charger regardless of what the thingy is plugged into.
But the only thing that would achieve is to overload/damage the source, which would say itself if it was capable of supplying the extra current in the first place 

But still there's a moderate chance it's not an outright scam, just someone who has no idea of what they're doing (again).

Well, hidden in a lot of text it seems to be doing exactly this: Signalling to the device that the charger is capable of high charging currents. In some rare occasions this could be useful: I have a Huawei cell phone, and it charges quite quickly on its factory-supplied USB charger (1A, I think). But from a variety of car chargers that should all be capable of supplying 1 to 2A, some of them supposedly iPhone compatible, it takes almost no charge current (i.e. the idle device will take about 8h for a full charge, and when using google maps+GPS for navigation the charger just slows down the discharge a bit). So if this thing would now convince the phone that it is hooked up to the factory charger, it would be somewhat useful.
So it might just switch the various resistors necessary for different phone brands to recognize a high-current charger to the USB data lines and test which resistor combination gives the highest current. It is maybe not a complete SCAM, but it fails to mention any of the many caveats and conditions that need to be fulfilled for it to perform as advertised.
