Runtime estimates are easier when you understand watts, watt-hours, inverter losses, and battery reserves. This guide shows a practical method for sizing a power station before you buy.<\/p>\n

Step One: List Device Wattage<\/h2>\n

Write down the running wattage of every device you plan to use. For appliances with startup surges, check both running and peak ratings.<\/p>\n

Step Two: Estimate Daily Use<\/h2>\n

Multiply each device’s wattage by the number of hours it will run. Add the results together to get total watt-hours.<\/p>\n

Step Three: Account for Losses<\/h2>\n

AC inverter systems are not 100 percent efficient. Multiply your total by about 1.15 to 1.25, then keep a reserve for unexpected use.<\/p>\n

Example Calculation<\/h2>\n

A 60W laptop used for four hours consumes about 240Wh. Add a 20W light for five hours (100Wh), then allow for losses and reserve; a 500Wh class unit may be suitable.<\/p>\n
