You didn't tell us what the amperage draw of the cooler is? It should work just fine on a 120v/20 amp circuit (max. 16 amp) and might be ok on a 120v/15 amp circuit if the current draw is less than 11 amps.
... just guessing from the info you provided and assuming this DOES NOT require a 120v/30 amp circuit.
