How do I work out what size (wattage) portable generator I actually need?
Start by listing every appliance or device you plan to run at once—fridge, lights, AC, pumps, etc. Then choose a generator with sufficient running watts plus headroom for starting surge loads.
As a rule of thumb, a quality 20 kW standby generator covers most whole‑house needs. In contrast, portable generators are better suited for powering essential household circuits or a few appliances at a time (not a whole house).
Always match the generator’s output to your load list—not the other way around.
Can a portable generator really run an entire home?
Yes and no. Technically, powerful portable models (e.g. 9,000–12,000 W) can run major appliances if paired with a proper manual transfer switch. However, they typically power only selected circuits rather than “whole‑house.” A professionally installed standby generator (usually 16–24 kW) is the safer choice for fully supporting HVAC systems, multiple air conditioners, or electric heating loads.
Portable power is excellent for backup essentials—just don’t expect it to do it all.
How long can a portable generator run on a single tank? Does it need “rest”?
Most models keep running for 6 to 18 hours per tank, depending on load and tank size Teague ElectricEcoFlow.
Generac states that you can operate a generator continuously if you keep up with oil checks, filter changes, and periodic fuel stops—there’s no need for enforced “rest breaks” as long as routine maintenance is followed
Are inverter generators worth the extra cost for running electronics?
Yes. Inverter units use electronic circuitry to produce clean AC power with Total Harmonic Distortion (THD) under 3–5 %, minimizing risk to laptops, routers, modern TVs, and smart home systems.
Standard generators often generate THD of 5–15 %, which can damage sensitive devices over time—and any surge may trip breakers or corrupt data
What maintenance and safety precautions should I take before using a generator?
Perform routine oil and filter changes (after the first 20–30 hrs, then every 100 hrs of use) to ensure longevity
