Turn the bloody circuit off at the breaker and look at the wire gauge installed in the outlet box. If it is 10 ga, you're good to 20 amps. (It will be marked for the gauge inept). Probably has a 20 amp breaker in the box to start with if the house was built in the last 30 years. Most garages are on their own circuit unless the builder was VERY cheap. I have a 20 amp circuit just for the garage opener in a 70 year old house & it's only a 15 circuit box.
