Hi, I've made a battery operated mobile charger using this circuit. I am able to charge the basic phones (with 2100mAh battery) with it. But the problem is, I couldn't charge any smart phones (with 1500mAh battery) with it. Even the charging indicator is not showing when I connect it to a smart phone. What could be the reason? and how can I solve it? Please help me.
