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.
