How to make your own quick charger for the cellphone or smartphone using a rechargeable spotlight. The quick charger can charge the smartphone from 10% to 100% in about two hours. It probably can charge the smartphone three to five times before it needs to be recharge again. It has about 27 Watt-Ah of juice (as compare to 5 or 6 Watt-Ah needed in most smartphones). It can also power a car/bike tire air pump. Very powerful and portable device.
