Which Adaptor to Buy?

I have an iPad Pro and sometimes hook it up to my tv set. I have an HDMI cable and it works fine but I'd like to be able to charge my iPad at the same time. I've been trying to find the appropriate adaptor but haven't had any luck so far. Any advice would be much appreciated. Thank you.
