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