How a Home Battery Runtime Calculator Works
Use a home battery runtime calculator to size backup for heating, broadband, lighting and refrigeration, with allowances for losses and surge loads safely.

How Long Will a Portable Power Station Run a Fridge and Freezer?
A fridge-freezer’s running watts cannot predict portable power station runtime on their own. Learn how compressor cycling, starting surge, inverter losses, battery reserves and measured energy use affect the calculation.
What Size Portable Power Station Do You Need for a Power Cut?
Work out the portable power station size you need by separating watt-hours from output watts, allowing for surge demand, conversion losses, reserve capacity and real appliance duty cycles.
