Simran AC-2000 Step Up/Down Voltage Converter Transformer 110V/220V - 2000 Watts,Black

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.

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 bought this because I live in Europe and have a lot of 110V stuff and 220V stuff I would like to be able to take back to the States one day. Though this is a great product, I am still trying to figure out what to use it for. You see, these transformers are an "on"/"off" appliances; which means they are either on (drawing 500 watts out of your wall) or they are off (a heavy paperweight). My flat screen LCD TV is 110V only, but I can run it and an XBox 360 on one 300W transformer... So you save money on the transformer purchase and the 300 watts (as opposed to 500 watts) coming out of your wall. I have a 2000W transformer too that I use to run my Dyson vacuum, but I only plug it in and turn it on when I am vacuuming. What I am getting at is just make sure you know how much power you need especially if you intend to use the transformer continually. If you just need to charge your 110V only electric razor for instance, you are only going to need a 100W transformer, as most razor chargers pull less than an amp of power. Most large electronics can run on 300W (a laser printer, maybe more). For a refrigerator or vaccuum, you are going to need a lot more juice: 1000-2000W. REMEMBER: voltage x amperage = wattage Most devices pull the same wattage regardless of voltage. Which means all those Europeans and Asians are using less amps, that's all.

Very nice

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.

Bought this for the TDP Therapy Lamp my in-law brought from China. They thought the normal converter would work but obviously the power isn't enough to reach the working level so the lamp couldn't heat to the desired temperature. I was looking around Amazon for a new lamp, which is around $180 at cheapest. Then I ended up with finding this transformer. It worked great and the max watt of the lamp is 200, which fits perfectly with this one. After hooking up, the lamp works like charm. Also the noise is almost unnoticeable. The only drawback is it's extremely heavy so might not be easy to carry for travel. Anyways, my in-law is very happy and so am I. :)

商品に凹み曲りがあり、明らかに落としている。交換要求したが、交換してくれない。製品パッケージもボロボロ 二度とここでは買わない。

Por fortuna no llegó dañado. Es verdad que la protección contra golpes es relativamente poca para un aparato tan pesado, pero puedo decir que trabaja excelentemente y estoy muy satisfecha con mi compra. Además la marca es garantía de confianza y durabilidad. 100% recomendable! Amazon hizo un buen trabajo en tiempo de entrega y me reembolsaron lo que sobró de las tasas de importación... cosa que yo ni sabía 😅

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.

I am very pleased with this transformer which I use regularly here in Canada, with my TV, VHS recorder, DVD player and Blu-ray player from the UK. It does the job very well though is makes the relatively low humming sound. No ac frequency difference is modulated onto the TV picture so I am very happy. Everything is working well with it, and yes, I received it in good time so very happy.
