Common questions

Where is my appliance list?

The working list on the Load tab is saved on this phone and comes back after you close the app. Named profiles live on the Profiles tab. Settings → Export gives you a JSON backup file.

The numbers look off.

Use the nameplate or the owner’s manual for each appliance. The 2× / 3× / 6× starting-watt helpers are labeled estimates you can override. Backup Watts does not guess appliance wattages for you.

Why only one starting surge?

Motors rarely start at the exact same moment, so the usual method adds running watts for everything plus the single biggest starting surge.

Where do the safety facts come from?

The Safety Guide follows CPSC and CDC generator basics: run it outdoors at least 20 feet from the house, never in a garage, keep CO alarms working, and never plug a generator into a wall outlet.

Does it cost anything?

Version 1.0 is free, with no ads and no purchases.

Before you email

Planning estimates only. Always check nameplates and follow your generator’s owner’s manual. Home hookup needs a transfer switch installed by a licensed electrician.
