It's definitely a bad idea to wire a 110V outlet with 220V. In particular, 220V is usually accomplished in the US using two hot wires, a neutral, and a ground. But 110V outlets only have a connection for one hot; you really don't want to be putting that extra hot on the neutral or ground connections of a 110V outlet because very bad things will happen. But even if you somehow have a single wire with 220V to ground, if you were to wire that up, the device could melt, short circuit, burn, and just generally be a major safety hazard.
(This depends a bit on what country you're in. I'm guessing North America, since that's the main market with this combination of voltages.)
The correct outlets look very different depending on the voltage. In particular, the most common 220V outlets (NEMA 6-15) have horizontal pins where normal 15A/110V outlets (NEMA 5-15) have vertical pins.
Maybe you're mistaking a 20A outlet for a 220V outlet? It would be safe to put a 20A outlet on a 15A circuit, but you'd get circuit breaker trips if your device tries to use 20A. But, again, it's not safe to put a 15A outlet on a 20A circuit because the outlet (and presumably anything you plug in) isn't designed to handle the current.
In any case, you may get more useful discussion on the diy stackexchange.
