Westinghouse iGen4500 vs Onan p4500i

The advantages of inverter generators over conventional portable generators is that they are more quiet, more compact, lightweight, more fuel efficient, also safe for sensitive electrical devices and usually more environmentally friendly. Seeing the advantages an inverter generator is more suitable for occasional use and specifically for outdoor activities like camping. An inverter generator is a good choice for when you don’t need a lot of power but do need convenient clean electricity that is easy to carry with you.

This remote start model features a rotating digital display that shows the remaining fuel, run-time left on the tank, the power load and lifetime run hours.Beside the remote start with a push-button, this generator has a pull-cord backup. At 98lbs this generator has a wheel kit and a telescoping handle, it weighs less than many competing inverter generators of equal power.  

There are four outlets on this generator, one duplex 120V 20A (5-20R) AC outlet, two 5V USB ports which are DC outlets, and one 120V 30A (TT-30R) this means that the generator is RV ready. The fuel-efficient Cummins inverter model has a gasoline fuel gauge, it can run for 18 hours on 25% load and 15 hours on 50% load. Thanks to its double-insulated case the noise rate for this generator is 52 dBA. The Onan P4500i is capable of paralleling with another P4500 inverter generator to reach 50A of power. Onan has less than 3% Total Harmonic Distortion which provides clean power for sensitive electronics and everyday appliances.

Conclusion

The Westinghouse iGen4500 and Onan P4500i have similar type outlets with 120V 20A and 120V 30A (TT-30R) AC outlets, thanks to the TT-30R both generators are RV ready. Also there are 2 DC outlets of two 5V USB ports which you may charge electronics, like mobile phones, conveniently. These two generators have the exact same weight at 98lbs, in addition both companies offer wheel kits and telescopic handles to help you move your generator easily. 

The noise rate at 52 dBA is offered by both of these generators, this means you can have a normal conversation at a few feet away. With a full tank, iGen4500 and P4500i can reach up to 18 hours operation. For the THD both generators also share the same number at <3% this generates a clean sine wave. The LED Data Center makes two of these generators easy to monitor its activity and status on the lifetime, run hours, remaining run time, fuel level, voltage and power output. 

Finally we can see that the Westinghouse iGen4500 and Onan P4500i have big similarities, so we can say that they came to a draw. Through the outlet type, weigh, noise rate and even the LED data center shares the same numbers and features.
