I do not recommend this power supply for the H9, as each outlet only provides 300ma of current per output. The H9 requires a minimum of 9v 500ma. You would have to combine the power of two outlets on you Micro Power and Mooer does not manufacture the cable. You would have to try a cable that combines the current of two outlets like the green adapter here: http://www.voodoolab.com/shop/index.php?cPath=22_24_33&osCsid=ptrom76a5jmurukb6ldhpke4s2

Then, you would need a reverse polarity cable that goes from center negative 2.1 mm to center positive 2.5 mm like this cable: http://www.voodoolab.com/shop/index.php?cPath=22_24_30&osCsid=p1hmh9e590bfue563pfti33bi5
