Predator 3500 vs Westinghouse 4500 – How do they Compare?


The Westinghouse iGen4500 offers a higher power output than the Predator 3500. While the predator 3500 produces a running wattage of 3000 and a starting watts of 3500 the Westinghouse iGen4500 goes further with a running watts of 3700w and starting watts of 4500w. The higher watts means you can power more appliances with it. You also do need so much of a boost to start it.

Fuel capacity and run time

The Westinghouse iGen4500 has a higher run time at 25% load of 18 hours compared to 11 hours for the predator. What this means is that with the Westinghouse you can power more appliances for longer. This makes it an ideal portable generator for home use. The Westinghouse iGen4500 is also more fuel efficient with a consumption rating of 0.19 GPH compared to 0.24GPH for the predator. Fuel efficiency is a big deal in today’s world of rising gasoline prices.

Noise output and portability

The Westinghouse iGen4500 is also quieter than the predator 3500 with a noise output of 52dBA compared to 57dBA for the predator. A quiet generator is a big plus when you are out camping and are looking for some quiet time. The Westinghouse also has a more quieter THD of <3% compared to <5% for the predator. This means it is more suited for powering your sensitive electronic equipment. However, the predator 3500 is more compact with its dimensions but is slightly heavier than the Westinghouse weighing in at 99.2lbs. against 98lbs.  Both generators come with a set of wheels for easy transportation but the Westinghouse iGen4500 comes with a telescopic handle as opposed to the double handle in the Predator 3500.
