Review on Simran SMF-200 Deluxe 200 Watts Step Down Voltage Converter: Perfect for International Travel to 220V/240V Countries; Great for Laptops, Cameras, iPhones, BlackBerry, iPods, and More! by Phillip Johnson

I bought two of these products to power several 50-60 watt devices. I was a little optimistic about plugging 3 devices (180W max) into the first transformer, but after a minute it got very hot and stopped working after about 5 minutes. Then I tried 2 devices (120W max) on the second transformer and it also got hot and stopped after about an hour. I originally used a transformer with a device and it worked fine for a couple of weeks. So I recommend running it at less than 80 watts (not 200 as advertised)! After testing with a wattmeter, this transformer is rated at 100w at 220v and 200w at 110v. This is definitely something the seller should write clearly, let alone 200w, and let the buyer guess!
