FAQ's

Frequently Asked Questions

What portable generator is right for me?

The right generator depends on your electrical load requirements, runtime expectations, portability needs, and the environment where it will be used, such as an RV park, job site, or home. That’s where we come in.

What is a portable generator best used for?

Portable generators are commonly used for RV power, emergency home backup, and temporary or remote power needs on job sites, construction projects, and industrial locations.

Can a portable generator power my entire home?

Some higher-output portable generators can support essential household systems or large portions of a home when used with proper transfer equipment, though permanent standby generators are better suited for automatic whole-home backup.

What size portable generator do I need?

The right size depends on what you want to power, how many items will run at the same time, and whether you need 120V or 120/240V output. Listing your equipment or systems you want to power in the contact form helps ensure an accurate recommendation.

What are the benefits of dual-fuel portable generators?

Dual-fuel generators allow you to switch between gasoline and propane, which can improve fuel availability, extend runtime, and reduce downtime if one fuel source is unavailable.

Can portable generators be used on construction or mining sites?

Yes, portable generators are commonly used on construction and mining sites to power tools, lighting, equipment, and temporary workstations in locations without permanent electrical infrastructure.
