Window Socket: Portable Solar-Powered Outlet Sticks to Windows, Charges Small Electronics

Ok the first problem I am seeing is the outlet is for a convention Alternative Current (AC) receptacle. This requires the internal electronics to convert the already stored energy from the battery or the energy being produced continuously from the solar energy, that is Direct Current (DC), to AC. Not to mention the phone charger or whatever else electronics you want to plug in have a input voltage of between 110-220V AC, depending on where you live. The solar cells combined with the battery will at most generate 12V DC if that, and so yet other electronics have to be implemented in that tiny thing to bump it up to the required voltage of 110-220V AC. The inefficiency seen from that little gadget is too much for it to be impractical. It would be much easier t just put a USB port at the end rather than a traditional AC receptacle.
