Accepted Answer

Hello. The UMI step down 220v to 110v voltage converter is designed for 100-120v appliance use in Europe. Its power rating is 500W, which should be used with appliances below 500 watts. How many power watts does your USA sleeping apnea machine use? That's for sure the 220v to 110v converter would work with the appliance if it's rated power below 500W. If it requires power over 500W, recommend choosing a step down converter with higher watts accordingly.

Question 4

Can I plug at the same 2 US devices rated 120v/65w each? Is it ok to plug 120v device to the 100v plug?

Accepted Answer

The device will power two devices of 65w each. As far as plugging a 120v device into the 100v plug, you should read the label on the 120v device to see what voltage range it operate, as it might be possible to damage it by giving it constant "brownout" conditions. You could use an outlet extender like this in the 120v outlet, and plug both devices into it. https://www.amazon.com/Philips-Splitter-Grounded-SPS1630W-37/dp/B07X3NT2Z7/ref=sr_1_3?crid=2RA07ONGQ4DDT&keywords=PHILIPS+3-Outlet+Extender&qid=1692620923&sprefix=philips+3-outlet+extender%2Caps%2C133&sr=8-3
