echpow ac Power Adapter (AC-L25)

Man! So happy to have found this. This will carry enough charge from an external battery pack to power my Sony HDR-CX190E while it simultaneously outputs to HDMI. Now, I can wirelessly stream video using my wireless adapter, all without worrying about the camera dying! Tried the single USB cable, as well. But that does not carry enough charge to run the camera and output HDMI.
