The control panel is divided into two separate sections, as shown above. One houses the receptacles, the breakers, the CO Guard warning and a grounding lug. The other panel has a digital display to monitor run time and is flanked by two bar gauges which indicate power use and fuel level. Here, there is also an On/Off activation button, LEDs for low oil, overload, and power, plus a button to activate the Quiet Power Technology (QPT- Eco mode), a main reset, and finally a fuel valve dial.
The part which houses the receptacles includes 2xDuplex 120v 20A outlets, 1x120v 30A RV outlet and 2xUSB ports, all of which are protected from the elements by covers.
As is normal for generators equipped with an electric start, you can also use the manual recoil mechanism to get the generator working.
The P4500 is CARB Compliant and has EPA approval, so you can use it in California.
The generator runs for up to 16 hours at a 25% load on its 3.5-gallon gasoline tank. If during operation the oil drops below a safe level a sensor immediately shuts the generator down.
The carbon monoxide warning system (CO Guard) automatically stops the generator as soon as it detects a dangerous level of this poisonous gas in the area of operation.
The unit ships with standard, non-synthetic, SAE 30 oil together with an oil funnel to facilitate filling, and without which owners say you could easily make a mess.
Briggs & Stratton include a 3-year limited warranty on this model for residential use and 1-year for commercial use.
