We developed the first user-friendly battery charging solution for end users in public locations in the world. It is compatible with all modern smartphones having a 30 pin connector, a Lightning connector, or a micro-USB one. Solve the problem is the daily one of having a dead battery on your smartphone. People currently have to carry portable batteries, carry power adapters, or use those rare charging stations where you have to either pay and close your phone in a locker or stand next to the station the whole time. The market potential is that of 1Billion smartphones worldwide, and locationwise the numbers in Italy are 90k restaurants and 20k hotels, without considering all conferences, venues, events and other locations in which our product may be used.
