Before purchasing a portable generator, it's crucial to perform a wattage assessment to determine your precise power requirements. This step prevents you from buying a generator that is underpowered for your backup needs or too large and wasteful. Start by compiling a comprehensive inventory of devices you plan to run during a power outage. This might include essential household items like heaters, routers, phone chargers, and sump pumps.

For each item, check its power rating—usually found on a sticker attached to the device. Look for the power consumption in watts (W). If the rating is given in amps and volts instead, use the formula W = A × V. solar generators for home backup example, a device drawing 5 amps at 120 volts uses 600W.

Next, identify any devices with high inrush current. Motors and compressors, like those in refrigerators or air conditioners, require extra power when they first turn on. This surge can be two to three times higher than the running wattage. Make sure your generator can handle the largest inrush current in your list.

Add up the running watts for all devices you plan to use at the same time. Then, pinpoint the appliance with the greatest startup load and add that surge amount to your total. This gives you the minimum power capacity your generator must have.

Don’t forget to leave some buffer room. It’s wise to choose a generator with a output rating 10–20% above your total than your calculated total. This ensures consistent power delivery and extends the life of the generator by avoiding chronic overuse. Also, consider the duration of expected outages. A larger fuel tank or better fuel efficiency can make a critical impact during prolonged blackouts.

Finally, think about weight, decibel output, and built-in safeguards like low oil shutdown and carbon monoxide detection. A power audit doesn’t just reduce unnecessary spending—it ensures your generator will work when you need it most.
