Simran AC-3000 Step Up/Down Voltage Transformer 3000 Watts Power Converter for Conversion Between 110 Volt and 220 Volts, CE Certified

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.

I exclusively use the Simran AC-750 voltage converter to power my HiFiMan Serenade Jr. R2R dac. I was using the smaller Simran AC-500 for awhile however that unit ran warmer than I liked, so I never felt comfortable leaving it on for extended periods of time. I purchased a LiteFuze LT-1000 thinking it would be an upgrade over my original Simran AC-500. The LiteFuze lasted 1 day in my system before I yanked it back out. It made my Serenade Jr. dac sounded irritating and harsh and I did not want to listen to it at all. That is when I decided to go back to Simran and step up to the larger AC-750. The AC-750 has an extra 250Watts of available power vs. the AC-500 and it seems to be the perfect match for my needs. The AC-750 is rated at 15x the power requirement of my Serenade Jr. so it cruises along with no strain and the metal case barely runs warm. Simran are the only voltage converters I have used that have not negatively affected the sound quality of my audio gear. I only wish it had an IEC inlet so I could power it with one of my high end TODN power cables. I think the retail price would increase if Simran knew these units were being used to power high end audio gear. If you have sensitive high performance electronics, I recommend Simran as your go-to choice for voltage converters. If you are only using appliances and power tools, then it probably does not matter which brand name you choose.

Very well made product, will assist in my work greatly!

Update - Been using this for over a year now and it has worked great. Wife has used her German Kitchen Aid that is 220volts 50/60Hz and with the Thermomix that is 220 volts 50/60Hz. She hasn't had any issues. The device it self can be plugged into a German outlet that has 220 volts 50Hz and can be used as a transformer to step down the power to 110 volts 50Hz or it can be plugged into a US outlet at 110 volts 60Hz and will step up to 220 volts 60Hz. It does not step up or step down the frequency though. If you are drawing power at 60Hz the output will be 60Hz. If you draw power at 50Hz the output will be 50Hz. I recommend you look at your device you plan on plugging in and see if it supports both 50 and 60Hz. If it does and the wattage of your device is below 500 you should have no problems. Just remember if you plug in multiple devices at the same time, you have to add up the wattage. So for example, if 2 devices are rated at 300 watts each, they will work fine as long as your input and output frequency matches but do not plug in both devices as the total will be 600 watts. Trying to pull more power or wattage from a device than what is recommended is the way a lot of electrical fires start. Original- Works great as long as you don't have devices where you have to also adjust the frequency. In Europe, many devices with motors are 50 Hz and in the US they are 60 Hz. If your device only supports 50Hz and you use it in the US, it will most likely cause issues. We use it for my wife's thermomix which is 220 volts only but supports both 50 and 60Hz. We just moved back to the US so we didn't want to get a new thermomix so this was the best way for us. We have been using it for almost 3 months without any issues. Thermomix has been working great off of it. Just be careful on the frequency support of your device. So if you are going to Europe and you need to step down to 110 volts, it will do that but the frequency will be 50Hz. If you need to step up to 220 in the US, it will support that but the frequency will be 60Hz. Most electronics support both 50 and 60Hz, but many appliances and devices with motors in them do not. Just look at your device where the power cable is and you should see a label with what power and frequencies your device supports.

Doesn't work. bought it with the thought of using. it sat in a closet for a couple of months. when attempted to use (first time) checked multiple times that the input is set on 220 V (as in my country), connected (first with a plug adapter) to live power socket, flipped the switch and nothing, no light no current nothing. Changed the plug (to have grounding) still nothing. Changed a fuse, nothing. Just a heavy ugly chunk of metal. Going to try and open it up next, hopefully not going to electrocute myself edit: thanks to a bad screw, I had to go find something to break it off with... it has been a while since I used my Dremel :) awesome first impression when taking apart... When opened, the first thing I noticed is the fuse's disconnected wire (circled with red in one of the attached photos) and copious amounts of glue (just indicates how "good" the build quality is)... so now I need to go find a soldering iron, which I'm not sure I have. still 1 star, NOT something I would recommend! edit 2 - "let there be light": found soldering iron, connected wire, there's light after flipping switch. connected a black and decker wireless screwdriver BDCS20 to charge. will update in a while if it is more than just a light Last update: It "works". It charged my flimsy screwdriver. I am not going to test it with anything big, nor am I going to check actual voltage. Me needing to open the BADLY BUILT thing and RE-WIRE any part in a completed product is more than enough to earn this negative stars.

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 bought the 2000 watts converter for a 1000 watts pressure cooker. I had it for a month now and it’s doing exactly what it’s supposed to. At first, it was set on the 220 outlet & when I turned on the pressure cooker it kept giving me error messages until I figured how to switch it to my 110 outlet. In case you faced the same problem, it’s in the back, a little handle that you need to pull down/ up depending on the voltage you have at your house.

I purchased two of these from another company 10/16/2016 and one died on 6/24/2018, so it lasted less than 2 years. The unit was temperamental right from the start. After a month I noticed that I'd get 220V for a few hours and then at some point it would start supplying only 110V. Switching it off and then back on would reset it 8 out of 10 times and I'd get 220V again. I had some concerns about this causing issues for the devices plugged into it. The reason I did not send it back was this clause included (Not by an Amazon seller): " Products which are improperly packaged and do not include manufacturers box will be refused. The merchandise must come back packed in the outer brown box it was shipped with the shipping label on it". I had a faulty unit but his only became apparent a month later and the crappy boxes were thrown away by then. I also bought one of these from Amazon on 12/6/2017 without automatic voltage selection. It arrived with a blown fuse, so it was DoA (Dead on Arrival). Considering the issues I had with my existing unit, and the fact that Amazon is a much safer bet when it comes to returning items, I returned it. This made it clear that Simran does not do great (or any?) quality control. I continued with the original unit until it died. I opened it up to see if it could be saved and found the following: The automatic voltage selection board seems to be the culprit. The board has some component specifications on it which were not followed. Marking on board -> Component Cap : 1000uF 50V -> 1000uF 35V Resistor : 5W 10 Ohm -> 1W 10 Ohm These burned out and caused additional damage to other components. Additional components damaged was a C1008 transistor, an N4007 diode and the relay on the automatic voltage selection board Simran used lower spec parts causing early failure. The rest of the unit seems well built and should really give you lifelong service, had it not been for the compromises made on this one board. My other unit has not given me a moment's issues, so the item you receive might be hit or miss. My advice: This product is good value for money, BUT get this from Amazon if you need it, and not from a company with questionable return policies. You may never look back or you may have to return it if you notice strange behavior.

Pues es muy buena

Llegó antes de lo esperado, excelente producto funciona perfectamente.

El producto es bueno, funciona bien y a la primera, me permitió usar en México aparatos de 220 V, particularmente uso mucho una afiladora, la hago funcionar más de 8 horas seguidas y el convertidor no se calienta en exceso ni suena mucho. Como dije, cumple lo que promete y lo hace bien.

Muy fácil de usar un poco ruidoso pero simple.

Excelente estado, funciona perfecto, hay que tener ojo por que venía para 220, se cambia fácil a 110.
