About OutageSizer

Size your backup power with real numbers. We build free calculators and reference tables for sizing backup power during outages.

How we work

• Every appliance figure cites its source and the date we checked it.
• We do not claim hands-on testing we haven't done. Product specs (when added) will come only from manufacturer pages, with a link and the date checked.
