Question: I have an American dehumidifier, with a 3-pronged cord, 410 Watts, 115 V, 60HZ, 3.8A. Can I use this unit & how shall I plug it into aSwiss outlet?
Document: I bought this since we moved from overseas and we had a few products that use AC 220v. I did my research on wattage and bought this to plug in our laser printer which requires 350 Watts. I was also able to charge my cordless drill at the same time with the use of an overseas powerboard.Just remember that if you want to use multiple devices at the same time, add all the watts together and multiply by 2 or 3.
I bought two cheaper converters before this one. None of them survived after 3 months. I have used this one for over a year. No problem at all so far. It is little heavy but compact in size. I used a power strip connected to this converter and have several appliance plugged in this power stip. The total power is close to 800 watts. The unit works perfectly.
I had 1000W mixer/grinder from India. Works great with this. Its very easy to use. No complaints so far. Remember to change setting (basically a switch) as per your voltage. it has universal outlet, can plug most types of plugs without converter.Little heavy.
Excellent Product and working without any issues for the past 6 months, no heating even though keeping it on for 24 hrs.I bought this unit to use in one of my Mixer's which was bought in India and needs 250 V supply.Highly recommend to everyone.
Goldsource STU-1000 Step Up & Down Voltage Converter Transformer with 5V USB Output - AC 110/220 V - 1000 WattI bought this item to use as a step up transformer from 120v to 240v so I could test products for export to Germany. I followed the directions and set the unit up properly but it does not output 240v. Instead of stepping up from 120 to 240v the jack on the front panel puts out only 120v.
I am stationed in Afghanistan. Although I live on an American military base, the current is 240. This converter is lightweight, and supports 1000 watts of electric pull. I have a small refridgerator, electric blanket, clock, light, and some charging devices hooked up to it.
I have a rice cooker from Korea that needs a higher voltage (700 Watts) than you can get from a US outlet. I bought this Goldsource transformer and it works great. It also has a on/off switch so I don't have to have it turned on all the time. I am quite energy conscious so it's great to have that switch.The transformer is quite heavy and bulky (as is expected). But other than that, I can't find anything negative to say about this solid product.
So far this product is working great..Easy to use, instructions are simple. The plastic adapter plug that came with unit was broken or it be 5 stars....
The construction is flimsy. While it is heavy, the trannies are of low quality. Lotsa of hum. Unusable for any home audio application.The 220V input bracket fall off after 3 uses. Very danagerous! I had to glue it in so it would not get loose and expose the  plug legs.Fuses got toasted easily buy hey at least it's not toasting my equipment.
I should not have bought it. It's got nothing to do with you or the product. I am using a c pap breathing apparatus from South Africa and it's not working. I do not have the 220v cord and transformer  for the unit as a result I have the unit working but not enough power to work the hudimifyer. I would be really happy if you can locate a power supply 220V for this unitThanks
Answer: Very simple-plug in transformer into wall socket (the plug has two rounded prongs -may need an adapter to fit, I'm not sure what types of wall outlets are in Switzerland). Then just plug US 3 pronged cord into the 110 V outlet on transformer. This transformer is rated for 1000 Watts, so you should be fine at only 410 Watts.
