How to read this page
Watt-hours: how much power a box holds. A bigger number means the box runs your things for more hours. If you only look at one row, look at this one.
Watts: how fast something uses power. This row tells you how many things the box can run at the same time. A fridge and a router need very little. A microwave or a space heater needs a lot.
Surge: a short burst some things need to start. A fridge or a pump asks for extra power for a second when it starts. A box with a higher surge number handles that start without shutting off.
The “Fridge + Wi-Fi” row is our own math, not the maker’s. We add the watts of a refrigerator and a Wi-Fi router, keep 85% of the box’s watt-hours, and divide. Estimates. Your devices may use more or less.
