Typical uses for this unit

A small laptop charger rated at 65 W is below the published continuous AC output. Check the charger label and count other loads.
A 100 W light or device load is below the published continuous output. Available runtime depends on usable battery energy and conversion losses.
A small appliance with a running draw below 500 W may fit the continuous output; compressor and motor startup still require a separate surge check.

These are examples, not a runtime promise or a connection approval. Fit My Needs checks your actual appliances with the existing calculator.
