I need to convert from 5VDC (either 1A or 2.1A) on a 20,000mAh battery to 9VDC 750mAh hollow post. Will someone help? I've done web searches and found 12VDC to 5VDC, 12VDC to 9VDC, 9VDC to 5VDC, just about anythingVDC to (anythingVDC except 9VDC).
My project is to replace my wall-wart supplied power with a battery for my 9-band equalizer, which will have my Free Lossless Audio Codec (FLAC) player connected to its input and my headphone amplifier connected to it's output. I'm nearly deaf in the 8KHz+ frequency ranges, and this little equalizer works wonders in boosting the upper-mid range and high range tones.
I think this may work:

Whaddya think?
Thanks in advance for you assistance.
