Predator 3,900W Dual-Fuel Generator Review

Summary

The Predator 72872 is a dual-fuel generator rated for 3,900 running watts with 5,000 starting watts. That combination gives it enough headroom to handle devices that draw extra power at startup while still supporting a solid continuous load once everything is running.

Because it is an inverter generator, the 72872 is aimed at delivering cleaner power than a conventional generator design, which matters when you are powering sensitive electronics rather than only simple resistive loads.

Power & Runtime

With dual-fuel capability, the Predator 72872 gives you flexibility in how you supply energy, which can be valuable when one fuel source is easier to store or access than the other. Its 3,900 running watts define the sustained output you can plan around for ongoing use, while the 5,000 starting watts help it take on short bursts of higher demand when motors or compressors kick on.

Noise is part of real-world usability, and this unit is rated at 61.7 dBA. That level supports operation with less disruption than louder open-frame designs, making it easier to live with during extended runs.

Portability

At 110 lbs, the Predator 72872 is a substantial portable generator that calls for deliberate handling when moving it into position. Its physical size, listed at 25 x 18 x 20.8 inches, helps you gauge where it can fit for storage and how much space it will take up when set up for use.

Those dimensions also make it easier to plan transport, whether you are loading it into a vehicle or allocating room in a garage or shed, since you can match the footprint directly to the space you have available.
