The Briggs & Stratton P4500 side panel has all your power outlets and circuit breakers. These include one 120 volts 30A RV outlet that can be used directly plugin for RV, 4 duplex 120V 20A outlets, and 2 USB ports that allow you to stay connected and keep multiple items powered simultaneously.

The whole outlets have plastic covers, protecting them from moisture and dust. Also, the entire generator has an impact-resistant plastic housing that reduces noise volume by the engine and protects your generator from dust and knocks.

There is also a LED display that informs to you about the generator’s fuel level, how much output you have used, and an hour meter.

How much power you can expect from The Briggs & Stratton P4500

When it comes to the power output, the Briggs & Stratton P4500 is fitted with224cc engine that allows it to power output 4500 starting watts and 3700 running watts. For this power output, you are able to run your small to large appliances like bulbs, fans, air-condition, refrigerators, and also your sensitive electronic appliance, like mobiles, TV, laptop, etc.

Fuel Economy

When it comes to fuel economy this generator is one of the best, Briggs & Stratton claims this. But according to my opinion, it is below average when compared to other inverter generators. The P4500 has a 3.5 gallons gasoline tank that will keep the generator supplied with enough fuel to run for up to 16 hours at 25% load.

This means if you run this generator at 50% load, you can spend the whole night or a day without refueling the tank and enjoy your parties and camping the whole day or night with electricity. You can run large appliances at your parties and camping. 

Another great feature that I like about this model is it comes with a fuel gauge so that you can check the generator fuel level. Usually, the fuel gauge does not come with most generators. Thanks to the company to provide this facility.

Weight and Noise Level

Despite the huge amount of power, one of the things we love about this generator is it doesn’t compromise on the quiet operation or weight. This generator operates at a soft 58dB operating volume which is considered a quiet inverter generator in this size. Because of the low dba, it is good for camping, outdoor parties, RV trips, and where you don’t like to listen to generator noise.

So if you’re looking for a quiet inverter generator in high output power with an average price then you’ll have to come to here for buying Briggs & Stratton p4500 inverter generator. This will power your homes or RV trailers with a low noise level that is considered enough quiet.

This model’s weight is only 115 lbs when it’s empty. However, the weight will not irritate you ever because the generator on either side some of the space that makes it easy to lift the generator easy by two people.

Parallel Kit

Although you will not see that is this generator parallel kit capacity or not.? Because there’s no specific mention of a parallel connection for this generator. But it’s a standard feature listed for the PowerSmart generator series. Therefore, assume that you can connect two Briggs & Stratton 30795 P4500 generators in parallel using the optional parallel connection kit. This will double your power output to 9,000 peak watts and 7,400 running watts power.

Best Design

Briggs & Stratton gave a great shape to this model since it has a telescoping handle and 2 wheels. A child can easily move the generator.

Besides that, both sides corner of the generator has some space for two people easily lift the generator by hand.
