5. ### current rate for charging

I have a source of about 10v and with a resistance load of 0.5 ohm i am getting current of about 200ma.Can I charge a mobile with it? if this current is not enough then please suggest me a way to increase current as i can sacrifice about 4v to get that current because i need 5 v to charge a mobile?
