Simran SMF-200 Deluxe 200 Watts Step Down Voltage Converter for International Travel to AC 220V/240V Countries, Ideal for Laptops, Cameras, iPhones, BlackBerry, iPods etc

I bought this for my daughter. She has gone to Europe twice and this unit continues to work for her. She did buy another, but it would seem that the mildly cheaper one could not put up with the strain. This will easily keep the essentials on your trip working. She has lent it to a friend of mine going to Spain and I expect to hear about consistent fabulous results. Good Job on this one !! Robust and wraps up easily. It is heavy, but it is robust !!!My friend borrowed this unit, and it worked perfectly for his personal electronics. But reading the other reviews, and some are inexplicably negative, I thought that the following would be important.When you plug in your device, you need to be sure you are not using too much power. This can harm the device, and so there is some home work to do here.1. Perhaps your personal electronic device has a charger with the wattage written on it. What a Godsend that would be because you simply have to add up the Wattage of the devices you are plugging in. Keep everything under the 200 Watts and you are good.2. If there is no wattage listed, you can calculate this by taking the VOLTAGE of the unit and multiplying this by the CURRENT. This will give you a value called Wattage. Voltage of course is measured in VOLTS and current is measured in AMPS.Small personal items normally have no problem, as the tablet I have in front of me requires 5.0 V (kind of typical for things that plug into USB ports - another wonderful hint!) and draws a current of 1.0 A - that is only 5 Watts. I can plug in many of those units into this one adapter. SO, when it comes to this type of personal device, this unit is wonderful !!On the subject of LAPTOPS, do realize that the adapter that came with your laptop is required to do two things, and likely at the same time. The adapter needs to provide enough power to run your laptop, AND charge up your battery. MANY laptops come with 65 Watt Power adapters, and again this is small enough for this converter. But if you are plugging in a few things for the evening, do remember this little Road Warrior secret. Your laptop draws less power than that when it is ONLY CHARGING. So, with a little trial and error you can plug in all of your electronics, and provided that they are only charging, this converter unit is a TREMENDOUS unit to have !!I still heartily suggest that anyone going to Europe will need one of these.Lastly, and this is outside of my area of expertise, this unit can have other adapters for lesser known areas of Europe and beyond where there are different power conventions. I believe that the voltages will still be 220 V, but the actual fitting is different. Do be sure that you do your research on that !!

I bought this for an unusual purpose and it worked great for me. I purchased a UV lamp for HVAC sanitization. The lamp is intended to plug into a standard outlet and remain on all the time, but I thought that it made more sense to have the light turn on only when the fan of the HVAC turns on. I went to wire it in and discovered that the fan is 230 volts, so that wouldn't work to power the lamp. I bought this to convert it down to the 115Vac the lamp required. The lamp is low wattage so it's perfect. I'm very happy. Since this is a review I thought I'd mention a couple of other things. For my purpose I just cut the plug off and wired it in directly. Most travel adapters have an assortment of different plugs that can be used depending on your needs, this one does not. The plug is a single European style without any other of the common plugs That may be needed in other countries . So if you want to use this for travel make sure that you look into your destination and have the correct type for your application. Also this is nothing fancy, it is literally just a 2 to 1 Transformer. Which makes it versatile because it doesn't really care about things like the line frequency. Also it should be really durable because it doesn't have a circuit board with delicate components to break.

I purchased this for my wife. I have universal adapters for foreign travel outside of the U.S. but I did not have a voltage converter. Most of my electronics will operate from 100-240v BUT my wife had a flat iron that is 110v only. Her iron required not just an adapter, but it required that the voltage be converted from 220v to 110v, thus the need for this product.The problem was that virtually all of the voltage converters say DO NOT USE with resistance heat items such a flat irons and hair dryers. I looked at the specs on my wife's flat iron and it uses 40 watts. With a 110 to 120v circuit, 40 watts is 1/3 amp. That seemed to be awfully small for a flat iron that got hot but I looked at the spec several times and sure enough it was only 40 watts.So even against the dire warning not use this converter with flat irons (and seeing no other alternative and failing to understand why a 200 watt converter would not work with a 40 watt load) I bought it.It worked flawlessly and the converter did not even get warm. The flat iron heated as usual and worked perfectly.So my suggestion is that if you are going to use this with resistance heat such as a flat iron that you stay WELL UNDER the 200 watt capacity and you should be fine.I deducted one star because the thing is HEAVY. Although it is compact, it feels like it is made of lead and will add weight to your suitcase. Otherwise a great item.

I normally don't write reviews, but I love this converter! I have bought several now, having been to Europe many times in the last 4 years as my daughter was in school in France. If traveling with my family, I buy one for everyone. In the beginning, I used one for several trips and it always worked well. Then as airline weight limits became stricter we have had to leave them there since they are a little heavy and we worry about airline weight limits coming home. So in the last 4 years, I probably have owned 8-10 of them. For the price, it is the most wonderful converter! Small, compact, works for computers, phone chargers, camera chargers, curling irons, etc. The only time I had a problem with one was when a friend tried to use an old high powered hair dryer and it blew out, so probably best to bring a travel hair dryer with dual voltage when traveling. But I can't say enough wonderful things about this converter. Cheap, reliable and we all love it.
