Champion 3100-Watt Inverter Generator Noise Level

A reasonably quiet generator’s noise level rating shouldn’t surpass the 60dB mark from 23 ft. That said, the Champion 3100-Watt Inverter features a 58dBa noise level rating at 23ft. That’s probably quiet enough for RV operation, tailgating or camping. You can even power it up at home in case of a power outage and still continue conversing as normal.

What We Like About The Champion 3100 Watt Generator

  • Portable – The Champion 3100-Watt weighs 98.4 pounds when the gasoline tank is full. That may seem heavy but you’ll rarely find other models of similar power and capabilities at that weight. They even added two wheels at the back to make it even more portable. 
  • User Friendly – You won’t need to decipher how to operate the generator as the overall design is functional for both experienced and novice users. You have a quick touch panel so you’re able to access all your controls in one spot. Even if you don’t know squat about oil change, it will shut itself off once the oil lowers to unsafe levels.
  • Compatible with sensitive electronics – I must say generator technology has come a long way. Back then it would have been really dangerous to connect your valuable devices to those noisy generators. But with models such as this, you can safely connect almost any device with confidence as the inverter is set up so it won’t over power your devices. 

Champion 3100 Watt Inverter Generator Problems

Since it’s a machine, you know it’s bound to have hiccups. So we rounded up the most common Champion 3100 Watt Inverter Generator problems, so you know what you might be getting into if you decide to buy it. 

It may die – The most common problem with the generator is that it may completely shut down without so much as a goodbye. According to popular opinion from some users, some units didn’t even make it through the night. But based on further research, the manufacturer is quite efficient when it comes to repairing faulty parts. They may ask you to either ship back the unit for repair, send you an on-call repair handler or replace the unit if the warranty period has not elapsed. 

Develops rattles after extended use – Some users say their generator developed an annoying rattling after a year or so of use. While some were able to fix the problem, others were left with a generator that promised super silent operation at the beginning, but an annoying rattling sound quickly wiped off that valued feature. 

Not that fuel-efficient – If you do the math, you’ll need at least 19 gallons of gasoline to power up the generator continuously for 24 hours at full load. So if you’re deep in the woods and you’re planning on running the generator at full load 24/7 you may want to carry extra fuel. Remember the Smart Economy Mode feature only works at 25% load and below.
