Space heater on 20A circuit with mini-fridge and work lights

I have a 20A circuit in my garage that runs two work lights and a mini-fridge. Wife makes us keep our smoking to the garage and outdoors, so I’ll run a space heater for 15-30min max while hanging in the garage. Plugs into its own outlet with nothing else running on the circuit but a fluorescent work light and a mini-fridge. I’m only using the heater when it’s really cold out, can’t imagine the fridge is using a lot of energy to keep a few cans cold at the temps. Any risks running the space heater? I turn it off and unplug it before leaving the garage.
