Question: I have a coffe machin from israel (220w) and i want to use that in usa (110w) if it's product give me the effect??
Document: This product works for all our appliances that we brought from Korea. However the fuse tend to give out easily so I had to replace it a few times for the same appliance I continuously use on it.
product description tells it can be used up to 100W loads. I want to use this item for my wifes hair curling  which is only 58W but it is not possible as soon as i connect the heater it blows the fuse.
I purchased this product because I am living overseas and need to recharge many US voltage items. The problem I am having is the directions are very confusing - I tried to use it and blew out the fuses, so I had to put the Transformer back in its box. I do not want to burn out my US appliances, so I will probably not use the product. I would return it, but since I was not in the US when I tried to use it, it will just sit unused.
Fuse is always getting off whenever I am connecting my appliance to it. i am using it to step up the voltage from 110V to 220V. First have kept the settings to 110v as per the manual give with it. I connected to power and start my appliance and fuse has gone. Didnt work for the given setting. 2nd time I kept the settings to 240v and follow the same and still the fuse gone. Dont know how this product work. Also there is no contact details for the technical help.
I use it to convert 115V to 220V so I can use a massage machine from Hong Kong. It is working perfectly for me, I am happy that I found this product.
I thought in first time i saw it, it wont last for long time! But after using it a lot. I changed my mind about this product. I totally recommend it, so light. And it comes with a substitute fuses that you can use when you have utilized the first one.
I bought this product 2 months ago for some appliances that I brought with me from Europe to the US.It works great, never had a problem. Doesn't get warm even after a prolonged use, no noise at all.Highly recommend it, worth every penny.
Hello I'm writing this review because at the beginning I was so happy with my transformer, the first day when I tried it was working but then never worked again, so now I'm so upset with it. I really want my voltage transformer.
As iI plug it in it would trigger the safety overload of my outlet so  I had to open the black shell , move the transformer and reposition a wire that was too close to another one. Easy fix but you would not want to have to do this!
When I just got it want check it out right away, plug it in outlet 110 volt the other side of the transformer have 2 outlets, ready to plug wireless microphone to 220 volts, see a lot of smoke inside transformer come out, unplug the power and feel unsafe.
Answer: I doubt that it carries enough amperage for a coffee maker.  You need to get a much higher amperage transformer. Pick a larger unit that is rated at 1500 watts.
