Question:

I’m trying to figure out the run time in case my load is very low like just for charging a phone or a laptop. What’s the maximum run time in idle, 1/4 load and how many watts or amps does idle put out?

The 4,500-Watt Portable RV Generator - 3,600 Running Watts - Propane or Gas - Electric Start # 333-0005 puts out 3,600 watts. At 1/4 load the maximum runtime hasn't been tested but is likely similar to the 14 hours because of fuel consumption. The amps used for a cell phone is around 11 watts and a laptop around 100 watts. The idle speed is the consistent running so the output is the 3,600 watts. If you are only running the computer and phone charger, then you definitely could use a much smaller unit as this won't be the most efficient option for that small a power draw.
