Before purchasing a portable power generator generator, it's crucial to perform a wattage assessment to calculate your essential load. This step prevents you from buying a generator that is too small to handle your essential devices or excessively bulky for your actual usage. Start by identifying every piece of equipment 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, consult the manufacturer’s label—usually found on a label or in the manual. Look for the rated output in electrical units. If the rating is given in amps and volts instead, use the formula W = A × V. For example, a device drawing 5 amps at 120 volts uses 600 watts.

Next, note whether each device has a surge or startup wattage. Motors and compressors, like those in freezers, well pumps, or HVAC units, require a significant surge at startup. This surge can be as much as 2–3x the steady-state consumption. Make sure your generator can handle the largest inrush current in your list.

Add up the total steady-state wattage you plan to use at the same time. Then, identify the device with the highest surge wattage and factor in its maximum instantaneous draw. This gives you the baseline wattage requirement for reliable operation.

Don’t forget to add a contingency allowance. It’s wise to choose a generator with a output rating 10–20% above your total than your calculated total. This ensures reliable performance and prevents premature wear by keeping it within safe operating limits. Also, consider the duration of expected outages. A enhanced fuel economy or bigger reservoir can make a big difference during extended outages.

Finally, think about ease of transport, operational sound, and protective mechanisms like intelligent safety systems including oil alerts and gas monitors. A power audit doesn’t just cut costs—it secures peace of mind when the grid fails.
