Simran AC-200 Step Up/Down 110v 220v Voltage Converter Transformer, 200 Watt

I bought this to use with a Mathmos Lava Lamp in the US, that I bought from the UK. After reading how to operate this converter, it was very easy to setup and power on my lava lamp. I've been using it daily for a couple weeks, and have had no issues. Other reviews noted an electrical smell or loud operation, but I have not noticed that at all. For the record, if this starts making noise or putting out an odor, I'll stop using it. But for now, it's doing exactly what it's supposed to. I absolutely recommend this for use cases similar to mine.

I got this so I could run a 220v Singer Featherweight sewing machine off a standard 110v outlet. My husband got me the Featherweight off of Craigslist, but didn't realize at the time that it has a 220v motor. Turns out it was brought over from New Zealand and the previous owner just got a new cord and plugged it into a 220v appliance outlet to use it. Not wanting to have to use it next to my washing machine all the time, I figured a voltage converter was the way to go. This one was the most affordable one I found, and it works great. Not too big or heavy to lug around either! It won't fit in the Featherweight case though (not that I expected it to). Do note that because of the frequency difference - 220v motors (of any kind) are designed for 50hz while the US runs on 60hz - will make the motor run slightly faster. A voltage converter can't change that, so you'll just have to deal with it. For a sewing machine it totally doesn't matter, but depending on what you want to use this for you should check into how this will affect your device.

Simram AC-200 It comes with two extra fuses. When opening the box, there was a slight oily manufacture smell, but it didn’t become an issue when using it (no noticeable smell). I use it for a flat screen TV which requires 220V and uses about 80 W. It works fine and is very quiet (no electric noise): important when watching TV. I turn it off after each use using the front switch (convenient), which unlike shown on the picture is horizontal. When I received it, the input current was set to 220V (back switch) while the plug is a regular US plug. Good thing I checked it and switched it to 110V before plugging it. Other than that, I am satisfied.

Very good product

We've left this on for over a month now without issues to test a firewall appliance and it just stayed luke warm and never got too hot to touch. There's a switch in the back where you can select the input voltage, either 110V or 220V. We've only used it in the US at 110V input and 220V output in the front. Please note that this is quite a bit heavier than travel transformers that are popular for temporary use. However, this transformer does not change the Hz from 50 to 60 or vice versa. In Europe, it's only 50 Hz, so this transformer can only take down the voltage to 110V but does not increase the cycles to 60 Hz. Likewise in the US, this transformer does not reduce the cycles to 50 Hz. This mainly affects devices that rely on timing such as clocks and the speed of motors. FYI...many devices like your cell phone/camera charger, laptops, and shavers are already 100-240V 50/60 Hz and usable worldwide with the appropriate $2 adapter plug. Just carefully check the label.

I purchased this transformer because I was moving to France. The transformer has a US plug and an EU adaptor. I used it one time and when unplugging the power cord from the outlet the adaptor fell apart. The adaptor is poor quality. I initially only plugged in power cords with no ground. After connecting a US plug with a ground to the transformer all of my electricity in my flat went off. Not sure if this was the transformer or the adaptor I purchased a new adaptor. The US plug on the transformer would not fit in the adaptor. The ground is too long. So I am throwing this away. I do not feel it is safe. I purchased another transformer in the mean time and am very happy with it.

Have happily used this converter for a month with absolutely no issues. It is powered on 24/7 to run an old 220-volt Bose Acoustic Wave radio from the European market and it does it well. The converter is heavy and is not for portable use and it runs a little warm, but not hot. Don't be like me and skip reading the little pamphlet that comes with it - I couldn't understand why it didn't seem to work until I realized there is a switch in the rear of the unit to select a 220 or 110 input voltage and it was switched to the 220 volt input at the factory. D'oh!! Anyway, it works just fine and it comes with a couple of extra fuses and a European converter plug in case you need one.

The transformer is very easy to use, but it stops working after less than 20 usages within 5 months

Me encantó, funciona como lo describe el fabricante. Lo uso de 220 volts para convertirlos a 110 volts. Y trae varios fusibles de repuestos.

excelente producto, entrega rapida y economico, ademas muy util para herramientas que tienen voltage de 220 y que no podemos usar en nuestro pais

Bueno
