Using the circuit above provided by ISB123...i made a phone charger but instead of providing 1 amp that i've expected it only provide around 0.12 amp and 4.1 volt...is this normal and how to increase the amp i was thinking if the phone need 1 Amp it should draw 1 Amp from the battery...maybe there is a mistake or something...and it takes only 4 minutes to drain out until 0.08 amp
