Rolling volt / yoyo

What if the relief goods, which are sent to the poorest countries, can't be used?
If the relief goods that need electricity are sent to the areas where electricity is not available, they will become useless wastes. We should solve their basic problem.
Children have access to a new play of yo-yo and they generate power, using the rotary power of the Rolling Volt.
The electric energy stored in the Rolling Volt is stored in the wireless multi-tap battery and once the relief goods are plugged in the wireless multi-tap, they work.
