There are mixed accounts on whether or not HDMI can be used to charge. The voltage and current spec for HDMI are 5 volts at 0.55 mA...the iPad charger, the 10 w charger, is 5 volts at 2 A. So theHDMI spec is no where near the power required to charge an iPad.

Sorry, I may not make my question clear.
I mean I use 30-pin digital av adapter. I can present things on TV but I can't charge my iPad at the same time.
Do you have recommendations?

Using the 30-pin dock connector with HDMI allows you to present material, but not charge at the same time. HDMI does not supply the power required to charge. You have to charge with the proper charger, then change to the adapter fot your presentation. The iPad isnot designed to do both simultaneously.

If u have a look at the bottom of the charger it should say 10w which is the right charger for the iPad if ur using the iphone charger 5w then it would not have enough power to charge your iPad.I have a pad3 which I use with this av adapter and it charges my iPad while I am using it.

I try the iPad charger 10w while presenting on TV, but power gets in only a few seconds then no power get in anymore. I have to unplug everything and directly use only power charger.
