It says its made by Stephill Generators
3KVA (my apols)
110/240v

Does it not have an information plate (or book) that states the wattage
output. It's a bit like "How long is a piece of string?" without that
information. You can get 3.5kva gennys that can run up to 3000 Watts, and
others that will struggle to power 1500 Watts. What make and model is it?
