Review on 🔌 Simran AC-500 Step up Down Transformer: Efficient 110 to 220 Voltage Power Converter, 500 Watt, Black by Raymond Simmons

Update. I've been using it for over a year now and it works great. The wife used her German kitchen helper at 220 volts 50/60 Hz and a Thermomix at 220 volts 50/60 Hz. She had no problems. The device itself can be plugged into a German 220 volt 50 Hz socket and can be used as a transformer to convert down to 110 volt 50 Hz or can be plugged into an American 110 volt 60 Hz socket and is stepped up to 220 volts 60 Hz. However, it does not increase or decrease the frequency. If you source power at 60Hz, the output is 60Hz. If you source power at 50Hz, the output is 50Hz. I recommend that you look at the device you are trying to connect and see if it has both 50 as well as 60 Hz. If this is the case and your device's performance is below 500, you shouldn't have any problems. Keep in mind that you need to add power when connecting multiple devices at the same time. So, for example, if 2 devices are rated at 300W each, they will work fine as long as your input and output frequencies match, but do not connect both devices as the total power is 600W. Attempting to get more power or current from an appliance than recommended results in many electrical fires. In Europe, many devices with motors have a frequency of 50 Hz, in the US it is 60 Hz. If your device only supports 50 Hz and you use it in the US, this will most likely cause problems. We use it for my wife's Thermomix which is only rated for 220 volts but supports both 50 and 60Hz. We had just returned to the US and didn't want to buy a new Thermomix so this was the best route for us. We've been using it for almost 3 months with no problems. The Thermomix did a great job. Just be careful with your device's frequency support. So if you go to Europe and need to go to 110 volts, that's enough, but the frequency is 50Hz. If you need to go to 220 in the US, that's supported, but the frequency is 60Hz. Most electronics support it both 50 and 60 Hz, but many household and motorized devices do not. Just look on your device for where the power cord is located and you should see a label that states the power and frequencies supported by your device.
