As long as nothing is relying on the mains frequency for timing

There's no timer, it's nothing more than a heating element with a bimetal thermostat.

dangerous Chinese appliances, bad record of fire, poor wiring unsafe insulation

I would not use  such junk in my house.

Check out the approval of the Chinese appliances, the safety compliance trademark may be counterfeit

Thus no valid UL, ETL, CE safety test.

Incase of any incident you will be responsible and liable

Be safe!

thankssomuch for warning.
these are things i am doing
- I am using this machine only in 14-50P nema plug rated for cooking oven 50Amps
- I am not using it continously for hours and hours, since its steam cleaner, I have to start and stop it many times
- the machine is always in my view
- i have fire extinguisher in my reach 24x7




can someone please tell me if 14awg wire is good enough to extend this machine cord?
factory cord is short for my usage from NEMA plug

I wouldn't hesitate to use it. Actually I'm tempted to buy one myself for cleaning stuff underneath cars.

#14 wire is good for 15 amps, if this thing is 3kW it will draw 12.5A so you should be fine. Depending on the length you might want to go with #12 wire, it's not *that* much more expensive. I like SJOOW or SOOW for this type of thing.

Yeah that's obvious. The only thing that comes to my mind are magnetic transformers, but as far as I understand the theory correctly, those designed for 50Hz will generally be happy to work at 60Hz. It's the opposite that would not necessarily be true.

Yes, any 50Hz transformer ought to be fine on 60Hz, it will run cooler and be more efficient, same with motors and solenoids. The opposite may not be true, if there is just enough iron for 60Hz it will saturate at the lower frequency.

James i need 30-40 feet of length extended. do you think 14awg will work?

Power lost as heat in this extension cord will be about 30W at 12.5A or 30W/(40ft*2) = ~0.4 W/ft, or double that if you calculate this for the 2-wire units of length. This isn't going to heat it up to a noticeable level, unless it's kept in a roll, and the voltage drop is going to be about 1%, so it should be ok.
