Simran SM-1650 Power Converter 50W/1600 Watt Travel Voltage Converter Step Down from 220-volt to 110-volt

it worked great on 220V in Ukraine. i used the adapter plug that i bought in a specialty travel shop to access the socket. RB Olympia, WA

Thank you.I 'm already send it to my family.

Brought this for traveling in Europe which had take more than ten days to get it after ordered. Using it in London for my heating pad, right after plugged in, a big noise came out from the converter and my heating pad burned. I never try again during the whole trip. BTW, most of the good hotel in Europe they provide either converter or dual votage plugs.

I took the SM-1650 Power Converter with me to Europe, where they use the 220 V current. I got to use it maybe 3 or 4 times before the thing blew up. I was stunned, because such items are usually uncomplicated and therefore quite durable. From what I recall, it wasn't expensive, so perhaps this is a case in point: you get what you pay for...

This product ( SM-1650 Step Down Voltage Converter for Travel 220 Volt 50W / 1600 Watts ) is actually two converters built into one.At 'Low' setting (under 50 Watts), it uses an AC transformer to convert 220V sinusoidal waveform into 110V sinusoidal waveform. This is the safest way to operate low-power, 110V-only electronic devices from 220V outlets.At 'HIGH' setting (50-1600 Watts), the converter simply uses an electronic switch to 'chop' the 220V sinusoidal input voltage into smaller segments, such that the average power delivered to output load is reduced. This is the same principle used by most incandescent lamp dimmers. It works reasonably well for simple HEATING appliances, such as travel irons or hair dryers. But if you try to power an 110V-only electronic appliance through this converter, the high-voltage stress will likely cause the appliance to break down and burn out within seconds!This is not to say that this product is completely useless, only that you have to be EXTREMELY careful about what you can plug into it. Unfortunately, some appliances fall into the grey area between 'heating' and 'electronic'. For example, most people will classify a curling iron (hair straightener) as a heating appliance. Yet it contains electronic circuit and will be damaged by this converter.The good news is that most portable electronics (such as chargers for cameras, cell phones, laptops, etc) are already designed to handle universal input voltage. Check the AC adapter of your appliance to make sure. If it says "Input: 100 - 240V AC", then you don't have to use a voltage converter at all. All you need is a set of adapter plugs (such as the inexpensive  Travel Smart Polarized Adapter Plug 5 Piece Set ), which allows you to physically plug into AC outlets in other countries, and you are good to go.Finally, check with the hotel of your destination to see if your room is already equipped with a hair dryer. If that is the case, you'll have two less items to pack for your trip.

This worked good for our trip to Sweden. The only thing is that when it it plugged in to the outlet its a little heavy and you have to make sure it doesn't fall out.

This voltage converter works exactly as advertised, I used it in Finland recently with my curling Iron and worked like a charm.

Purchased these for use on deployment to Africa and even though they do what they are supposed to the had the problem of not being able to stay in the outlet with out being propped up. Also what ever you do DONT TURN THEM UPSIDE DOWN! I did this and the thing started smoking.

Great peace to use for travellingGreat west shipping service was fast and came on timeVery well recommended to buy for your travel needsGreat jobKeep up the good work
