Umm a 220VAC going into a 110VAC equipment will not have a pretty end. That why most devises IF they do support both have a switch so you can choose between 110 or 220. Why. Simple. Diffrent transformer. Usually a trasformer either increases or decreases voltages (usually decreases depending on the circuit) to a couple of voltage output. Usually a 5 VAC and 20 VAC. that from 110. Do that with 220 and you get 10VAC and 40 VAC. In otherwords you WILL smoke smothing at those specs. So run your equipment at Mfg recommened settings. If it has both try 110 and run more "circuits" to the outlet.
