You want to charge phone using solar power? On phone its size would be small and inadequate for smartphone to charge it faster than its consumption. However same idea about charging phone with sun light was achieved on cheap phone, I saw video on Youtube.
What do you mean as "Too many cables"? Most chargers plug into electrical socked, and have a lead to plug into the phone. Don't even think about just splitting low-voltage cable between several phones.
There are commercially-available chargers with multiple outputs, if this is what you ask for (that is, a charger which plugs into a power outlet with several USB outputs).
Not too many cables means not needing to plug each smart phone.
For instance I heard there was some sort of strip on which you can put a smart phone and it charges without being plugged to it.
That way you can have one strip with many smart phones on it, and only need one cable for the strip itself.
Know what I'm talking about? If so, do you think the idea is feasible?
