Pair Duofone Concept

In addition to the futuristic appearance (Duofone in the pictures looks very, very stylish), this device is interesting primarily for its "paired" functions. In a single copy, this “tube” is just a beautiful trinket (the filling is not the main thing here, it’s just a concept anyway). The functionality laid down in the name is revealed in the presence of two Duofone. It's simple: devices can be combined into a single module. As a result, we get a twice as large screen, which is already useful for watching videos and reading books. In addition, the designer “laid” in his concept the ability to recharge the dead battery of one phone from the still “live” battery of the second.

It’s clear that Duofone is nothing more than a concept. And that even the prototype of this phone is likely to never come out. But the idea of “paired” devices that complement each other and can, by the way, serve as a wonderful gift for a pair of close people is very good.
