For comparison, a standard household circuit in the US is 110V, 20 amps, which will max out at approx. 2000W. A wall socket just won't provide more than that- the socket itself can fry (unless it is a 30A outlet) or you'll pop the breaker/fuse. Specialized circuits for things like an electric range, dishwasher, water heater, and so on have much thicker wiring and beefier breakers, so they'll handle more, but for the usual wall outlet, you're looking at about a 15 or 20 amp max on the circuit (15A if you're in a crappily wired apartment, 20A in a decently built house).
