Review: Not bad
Review: La mejor relación peso-potencia para camping y emergencias - Este generador de GENMAX es una verdadera joya para quienes buscamos portabilidad sin sacrificar potencia. Lo que más me sorprendió es lo increíblemente ligero que es; puedo moverlo con una sola mano sin esfuerzo, lo que lo hace ideal para viajes en camper o para sacarlo rápido durante un apagón. El Eco-Mode funciona a la perfección: ajusta las revoluciones automáticamente según lo que conectes, lo que lo hace extremadamente silencioso y permite que el tanque de gasolina rinda muchísimo más.

## Questions & Answers

**Q: How long will it keep a fridge & small box freezer going?**
A: Thanks for your question, in factory we had done the fuel consumption test with 25% loading(450w) which is about 10 hours, so when I check the specification of example of fridge & small box freezer the output is about 92w ( Power Supply：115V/60HZ  Amps:0.8A Freezing capacity： 31.1L/1.1CU.FT ), which is lower than our 25% loading, so it will keep going over 10 hours.

**Q: Can anyone please tell me how to bypass the co sensor?? I can't put the generator in my RV box, it keeps shutting off.**
A: It's none of my business how or where you put your generator, but if you try to use this in the "rv box" and you are living inside the rv...you would absolutely be putting your life in danger!!
There has to be an "exhaust" pipe, which puts the exhaust gases outside the rv, or death could result.

**Q: Will this generator work in the us ? shows 50hz instead of 60hz**
A: Mine was 60hz and does work very well. Nice generator.  Very low noise.

**Q: What is the run time of the 2200W generator on non-eco mode?**
A: We ran this generator for about 6 hours at a time while camping that is all i can say. I have no idea about any eco setting,  sorry. It worked si well, very pleased
