500W Pure Sine Wave Voltage Converter US to Europe, 220V to 110V Converter for European Travel, Power Converter Adapter Combo PD for CPAP Hair Straightener Cruler Shaver Toothbrush Laptop Camera Phone

I’m living in Hungary and collect old tape recorders. Among them I have two old USA made cartridge players as RCA Victors Sound Tape Cartridge Recorder and M2 Revere Stereo Tape Cartridge System. To listen to them I needed 110V 60Hz pure sine wave power. Buying this Doace Voltage Converter was the best solution.

Received my order. I purchased for trip to Scotland. I will let you know how well it worked when I return.

Powered CPAP and able to charge phone

My order arrived quickly and packed well for the shipping to Hawaii. Using this for three upcoming trips and hoping it works well in foreign countries.

Worked fine for 3 months in Europe. Great Britain, Netherlands, France,Italy and Spain. Sometimes I had to use a combination of plugs (that were supplied) to access the outlet. Sometimes a bit "wonky" on set up in a new country but just press the white power button and everything worked well again.

I bought it for our upcoming trip to Europe. The USB C ports do not work. iPhone flashes too much voltage so they are useless. I bought it to give my CPAP a 120V supply which it did. I am hoping that the rest of the converter keeps working to do just that for the remainder of the trip.Even though it was purchased on 4/11 and my trip started on May 15 it is only been used for 6 days of use. I am out of my return window. To make this right I want either a return or a replacement.

I recently traveled with layovers all over the world in Europe and Asia. This power converter worked very well and had no trouble at all. It handled multiple chargers at once and did not slow down on the power it gave out.It has a function to cool it self, that way it does not overheat. It comes with multiple plugs to make sure you can plug in no matter where you are in the world. It is very easy to use and a great tool to have while traveling as some airports don't have USB plugs or USB C plugs.I was also able to use it on the plane with no issues.

Seems picky regarding what can be connected. My interpretation is that, on top of the documented limitations, it does not like electrical motors (which is not mentioned in the description). Remember many (most?) external power supply for tech devices only need a plug adapter not a voltage&frequency conversion.
