How to Choose Generators

Power Output

Choose a generator with enough power for your office needs. A higher wattage rating means more devices can run at the same time. Look for at least 3000 running watts for basic office equipment. If you have more devices, consider 5000 watts or more.

Fuel Type

Generators can run on gasoline or propane. Dual fuel generators offer flexibility and longer run times. Decide which fuel you prefer based on availability and cost. Propane is cleaner and can be stored longer than gasoline.

Portability

If you plan to move the generator, consider its weight and design. Look for features like wheels and handles for easy transport. A lightweight model under 50 lbs is easier to carry. Heavier models may provide more power but can be challenging to move.

Noise Level

Generators can be noisy, which may disturb your office environment. Look for models that operate under 60 dBA for quieter operation. If noise is a concern, consider inverter generators, as they tend to be quieter than traditional models.

Run Time

Check the generator’s run time on a full tank. Longer run times between refueling means less interruption. Aim for at least 8-12 hours of run time at a 25% load to keep your office running smoothly during power outages.

How We Reviewed

Where our data comes from

Our information comes from trusted manufacturer specifications and customer reviews. We looked at over 20 different generators to find the best options. Sources include manufacturer websites and user feedback from online retailers.

How we built this shortlist

We focused on generators that are best for office use. Each product was evaluated based on power output, fuel type, runtime, and noise level. We filtered out models that did not meet our minimum specifications.

What we ruled out and why

What we did not do

We did not test any generators ourselves or take lab measurements. All information is based on research and reviews. No subjective scoring or personal experiences were included in our evaluation.

How often this page is updated

This page will be updated regularly as new models are released and reviews change. We aim to refresh our content every three months or sooner if there are significant updates in the market.

Frequently asked questions

What is the best generator for office use?

The best generator for office use is the Westinghouse 12500 Watt Dual Fuel Generator. It has ample power and a remote start feature, which is great for convenience.

How much power do I need for my office?

A generator with at least 3000 running watts is recommended for basic office equipment. For larger setups, consider models with 5000 watts or more.

Are propane generators better than gasoline?

Propane generators are often cleaner and can be stored longer than gasoline models. They may provide longer run times but can have higher initial costs.

What is the quietest generator for office use?

Inverter generators are typically the quietest. Look for models that operate under 60 dBA for minimal noise disruption in your office.

How long can a generator run continuously?

Most office generators should run for at least 8-12 hours at a 25% load. Check the model specifications for exact run times.

What to look for

Power Capacity

Power capacity is important in selecting a generator. Look for models with adequate wattage to support your office equipment. A generator that offers running watts significantly higher than your total equipment load will ensure reliable performance without overload.

Portability Features

Consider how portable the generator is. Features like wheels and handles can make transportation easier. If you need to move it frequently, a lighter weight under 50 lbs is preferable. This will allow for easier relocation between different office settings.

Noise Emission

Noise level is an important factor for office use. Many models range from 50 to 80 dBA. Look for generators with noise ratings under 60 dBA to avoid disrupting work. Quieter generators can be more conducive to a productive office environment.

Fuel Efficiency

Fuel efficiency affects how often you need to refuel. Generators with longer runtimes at lower loads are generally preferred. Aim for models that offer at least 10-14 hours of runtime on a full tank for extended use without interruptions.

Safety Features

Safety features are essential for generator use. Look for models with low oil shutdown, overload protection, and CO sensors. These features help protect both the generator and your office equipment from damage.
