SimranSM200J Japan to USA 200W 100-volt/120-volt Step Up Down Voltage Transformer

Works great, price wasn’t bad also has a switch for reverse incase you wanted to use it in Japan.

-UPDATE-(3/3/12)Still running as new. No issues, rice cooker no errors. Japanese bread maker is producing awesome bread.The Kotatsu table runs better with the TRANSFORMER.When we are lazy to move it from the kitchen to living room then we use the home outlet to warm the Kotatsu table up (QUICK) and then turn it off [prevent damage(time depends on you, 10 min for us)].Natural body heat keeps a Kotatsu table warm when you have central heating available.--ANOTHER NOTE--The Japanese Vacuum cleaner will not make it in the states (give it up) because we did not use the transformer for it only regular power. I do recommend the LG Kompressor Canister PetCare Plus Vacuum Cleaner equivalent to Japanese style in America. Only 3 times more powerful. Worth it.--fin--It is a TRANSFORMER and not a CONVERTER, but I am referring to it as a converter because we didn't even know what we were looking for when we needed something to change the power when we got state side.Moving back to the states, we didn't want to sacrifice all the appliances we purchased in Japan. I was happy that Amazon had this converter for sale. No need to search randomly on the internet to see if your Japanese appliances will work on 120 Volts and 60HZ power (US).The rice cooker had no problem functioning on 120V 60HZ while we waited for the converter. Ofcourse the rice will be extremely hot when it's BUZZED UP with those additional 20 volts and this will eventually ruin the rice cooker. We tried a similiar converter from Home Depot which made the rice cooker display "ERROR".Now the rice cooker and bread maker work simutaneously off this one transformer. The rice cooker needs 400 WATTS and the bread maker requires 500 WATTS. Bread makers are very precise appliances so we were not even going to attempt to run it with out the transformer.I will update this review when we try out the Kotatsu Heating Element. Any appliance used for heating human beings should never be used if they only require 100 VOLTS. Even on the lowest heating setting it will be about .4 times hotter then its usual heat when used with 120 VOLTS.If you need a converter for an appliance with high watt requirements (IE: JAPANESE KOTATSU TABLE) you need an extra WATTAGE BUFFER to ensure stable power output/no damage to your appliance. For the best results it should be 3 times the needed wattage. This is why we didn't want to buy a cheapier converter with less WATTAGE CAPACITY.Before you start wasting money at local retails and shooting in the dark, just purchase this Transformer.

So I killed my 500 watt one with an appliance and needed to get a new one. I live here in Misawa Japan out in town and wanted to use my new counter-top oven which I bought on base. I noticed the unit is heavy and appears to be well built. I have had it for about 6 months and have had not problems running a crock pot and a rice maker at the same time. I would buy another one if this one dies.5-7-13I had it for about a year and then it died suddenly in the middle of cooking chicken. I think something happened to the outlets on the front of the box. They were so tight I had to wiggle and push the plug into it and yank/jerk the plug out of it. I am sure all that abuse couldn't have been good for the box. I ordered a PowerBright VC-2000J Transformer from the company's website as they wouldn't ship Prime to my APO (that's a different issue). I wouldn't order another Simran.

It works really good. It seems out the right voltage works good it does what it supposed to do.

At first it kept blowing fuses and I was running just a refrigerator and coffee maker so I switched it to run my home theater setup and it works fine but every-so-often it shuts off and i have to tap it a few times and it turns back on. Something inside is loose I guess but other than that it seems to work fine.

Works perfectly.

I bought a Japanese breadmaker and thought it would work in U.S. Unfortunately the manual specifically asked the voltage to be 100V. So i had to get a transformer. It took me quite a while to figure out which kind/brand to get.I read almost all the reviews on the manufacturer's website and on amazon. It did come to my attention that quite a few people complainrf it got burned soon or died within a couple of months. But I also noted several people mentioned that extra transformer power headroom should be considered. I had no clue how much is considered adequate. So I emailed the customer services of two manufactures, they both said to leave a margin in between of three to four times for the power surge. Since my breadmaker is 100v 50/60Hz 370w, 2000w should be safe and of course alot more expensive. If you are unsure about what type to get, I suggest you contact the manufacturer's customer services.I also asked them about the warranty and both said it is 5 years. I have only used this for 2 weeks and so far no problem with it. If it goes wrong, I will for sure update it here.

Using this to power a Japanese-market TASCAM MD deck, no issues at all.

Works well with my Japanese rice cooker, as I brought back a rice cooker from japan and showed the H04 error message, instruction stating the rice bowl is not inserted when using Canadian voltage 120V. Once I got this transformer it made the rice cooker work perfectly.I’m guessing the higher voltage from Canada outlets causes the machine to output the H04 error.

Solid build quality, no complains.

Funciona bien. Se dificulta un poco introducir los enchufes japoneses, pero bueno, de menos ya tengo como prenderlos de forma segura, funciona bien. algunos mencionaron del ruido que hace pero, yo no he escuchado nada de nada. Quiza mejoraron el producto?

It doesn’t work soon after using it, junk product

Perfect - works great and price was good too.
