Wattcast: Outage Power Planner

When the power goes out, the first question is simple: how long will my power station last? Wattcast gives you the answer in seconds, with no internet connection needed. Pick your power station, check off the devices you want to run, and see your estimated runtime, the time your battery will run out, and whether your unit can handle the load. PLAN WHAT YOU CAN RUN • Popular power station models preloaded, or enter any unit's specs • More than 20 common devices with realistic wattage, from refrigerators and CPAP machines to routers, lights, and space heaters • Refrigerators and freezers modeled the way they really work, cycling on and off • Warnings when a load is too big or a startup spike could trip your unit • Add your own devices, and account for devices running from DC and USB ports OUTAGE TIMER Start the timer when the power goes out. It counts down your estimated battery and alerts you when about two hours remain. Enter the percentage shown on your power station's screen, and the timer switches to your actual drain rate so it gets more accurate as the outage goes on.
