Safety first

We've designed our portable generators with your safety in mind. Snap-fit rubber outlet covers keep vital connections between your valuable devices and the generator protected against moisture, dust and debris . We've also installed ground fault circuit interrupters (GFCI) that shut off the power if it detects an issue in order to keep you safe.

4 in 1 digital display

All the vital information you need to operate your portable generator in a single display: voltage in use, frequency (Hz), current runtime in hours and total hours ran.


The Cat® RP5500 is flexible enough for small jobs, home power outages, or a campsite.
