[No Fan No Noise] Power Voltage Converter by E-POLAR, Power Converter and Travel Adapter 220V to 110V Pure Sine Wave Power Step Down Converter EU/UK/AU/US/in Worldwide Plug Adapter

Bought for a recent Danube River cruise from Germany, as well as several nights in other countries in the region. Worked great, quiet, no sounds. Used 110v as well as USB-C and USB-A. Bought because of multiple adapters to use in other countries for future trips.

The media could not be loaded.  Stopped working 3 days into my trip after only using it twice (once in the hotel and once on the plane). Now when plugged in, the red error button is lit up and nothing is powered/charging. No instructions on how to resolve this problem. I found it strange that there was even an error light to begin with. I should have questioned why such an indicator exists... Hoping I'll be able to get a refund. I'll have to manage without this for the duration of my trip, too bad I gave away my power bank to someone during this trip, as this device is not as reliable as expected.

I was a little sceptical about purchasing this voltage converter but it worked wonderful for me. After trying it on an item that didn't matter if it blew up or run down.After all that I used it to charge my cell phone and tablets. It worked great.It also easy to know which plug you need because of the markings.

Travelled to Poland and after using the voltage converter twice to charge a rechargeable Water Pik portable water flossing unit, the error light turned on and the outlets on the voltage converter no longer works. It’s disappointing and aggravating since I bought this specifically for this trip. Terrible quality.👎👎👎👎👎

Does not work after 3 weeks.

I used this product on my Carnival cruise to charge multiple items. Since the cruise ship only gives one 110 outlet in the cabin space, down stepping the the 220 outlet definitely comes in handy. This transformer charges your devises quicker.

It is always difficult to purchase these sorts of things with confidence because often you are not able to utilize them until you are half way around the world. I read the reviews before purchase and felt that this would be a good choice for our trip to Germany and Austria. I bought 2, one for my husband and one for myself to be able to use our CPAP machines while we traveled. Initially, they worked fine, but within 5-7 days, neither would support the CPAP machines due to an "error" (indicated by a red illuminated button on the unit) I am very disappointed in this product, especially since there is only a 30 day return window (long past) for this product when ordering through Amazon. Interestingly enough, the USB ports still worked even though the machine indicated "error"....but this did not help with the important medical need of having power for the CPAP machine. I would recommend having some other kind of backup if you are going to purchase this item, just in case it fails.

Nothing, it very good

Se quemo en la primera usada y como estaba de intercambio no se pudo cambiar o devolver en las fechas que Amazon ofrece. Horrible. Dinero literalmente regalo

Lo llevé a Europa y al momento de probarlo literalmente generó un apagón en la habitación del hotel. El "convertidor" se estaba quemando y pudo generar una tragedia.Ahorrate tu dinero y no lo desperdices. Es de los peores productos que he comprado en AMAZON

Lo utilicé para cargar celulares y computadora, y después de 4 semanas hizo un corto, se quemó e incluso nos dejó sin luz, cero recomendable
