UPS Battery Backup Run-Time Hours Calculator

Estimate how long an uninterruptible power supply or deep-cycle battery bank will power your equipment during an outage.

Convert continuous power (Watts) to electrical current (Amps) across DC, single-phase AC, and balanced three-phase AC circuits.

Calculate required generator wattage for home backup, RV camping, or jobsite tools with motor surge handling and 25% planning headroom.

In Development

Calculate required wire gauge based on circuit amperage, voltage drop limit (typically 3%), and circuit run distance.
