When the power grid goes down, a portable generator can keep your household running smoothly.
Portable generators come in gasoline, diesel, propane, and natural gas variants. Gasoline generators are lightweight and affordable, but require frequent refueling and produce higher emissions. Diesel models offer better fuel efficiency and durability for heavy-duty use. Propane and natural gas generators provide cleaner combustion and are ideal for long-term emergencies.
Generators are rated in watts and the total available power must match your essential appliances. For most homes, a 5,000 to 7,000-watt generator covers lights, refrigerators, and small HVAC units. Pay attention to the surge rating for starting appliances such as the fridge or air conditioner. Efficiency depends on load; operating at 50–60% load usually yields optimal fuel economy and longevity.
Look for a generator with a built‑in transfer switch or an automatic power transfer system so you can switch from mains to generator power with minimal effort. A rear or side access panel can simplify fuel refilling and maintenance. Lightweight chassis and compact design mean you can transport the unit to an alternate site if the storm damages your primary location.
Make sure the generator includes safety shut‑off switches, low‑oil alarms, and carbon monoxide sensors. Install the unit outdoors or in a well‑ventilated area, at least 20 feet from windows and doors, to prevent toxic gas buildup. Adhere to local regulations regarding generator use and keep the unit’s manual handy for quick reference.
