@Rasp Residential branch circuits are often 15A so 1800W would (ideally) open the circuit breaker fairly quickly. Which would make space heaters even more of a nuisance and make even more people do the dangerous shit they do when their OCPD's are working correctly.
I agree, just plug it into the wall but if the power strip was listed for 125% of the load I wouldn't see an issue plugging a space heater into it. The only issue then would be the power strips would be more expensive lol
