What if you could charge a smartphone battery enough to just walk away? This has been created by a Filipino teenager 15-year-old named Angelo Casimiro. Casimiro’s artificial Charger not only be used for a smartphone, but for all kinds of devices that have a USB port.
Casimiro said that the homemade charger can charge the battery with a capacity of 400mAh Lithium-ion battery with a way to walk for 8 hours. The battery charge level of the charger is still lacking. Especially when there is a battery on a smartphone has a large enough capacity, especially at the high end devices.
