RUNTIME MATH
Wh describes stored energy; W describes how much power can be delivered at once. Both numbers matter for a successful setup.
Estimate runtime for heated blankets, refrigerators, laptops, and projectors using Wh, W, and conversion efficiency.

For AC loads, WattMatch uses 85% as a transparent starting assumption. An 864Wh station at 80W estimates to about 9.2 hours.
Blankets and refrigerators rarely draw their label wattage every second, so actual runtime can move above or below a simple estimate.
Motors and compressors can need a short burst above normal draw. Continuous output and surge capability should be checked independently.

FAQ
Inverter conversion, internal electronics, and protective shutdown reserve consume part of the stored energy.
Watts determine whether a device can run; watt-hours estimate how long it can run.
