## Questions & Answers

**Q: will this work for an american toaster oven? a ninja blender ? a food processor ? hand blenders?**
A: NO. This unit is NOT designed for such high power consumption devices as blenders toasters or food processors. A typical hand blender consumes 700W, i.e.  SEVEN TIMES the capability of the Mercury 651.004.

**Q: I've just purchased a Rowenta VU5551 16" Stand Up Turbo Silence Fan from the States.  125Volt Fuse 2.5 Amp Max. Would this be OK for this product?**
A: In my opinion this step down transformer is under rated for the out put capacity you require.  I think you should get higher amperage transformer.

**Q: I live in Norway, but my curling iron is from the US. Can I use this converter to transform the voltage, and then use a UK too Norway converter?**
A: Our converters are not suitable for items such as hair dryers, straighteners and curlers. The reason for this is that although these items may indicate that they do not use much power you are not given the full story. When these items are plugged in and initially turned on they use an incredible amount of power in order to get them up to temperature in such a short period of time. Any statements of wattage are usually indications of what power is being consumed when the item is at temperature and is ready to use and not what is required to reach that optimum temperature.What i would suggest is that you contact the manufacturer of the particular item in question and ask them "What is the peak power consumption?" or "What is the peak INPUT wattage?" Of the item and make a purchase on that basis. We don't generally have converters to suit these kinds of products but what i would also advise is, on the basis of the information you receive from the manufacturer i would buy a converter that is more powerful than you need. The reason for this is that electrical supplies can fluctuate and 'spike' which inadvertently raises the wattage going through the converter, if the converter cannot cope with this increase it will blow and it wont be something that is covered by the warranty.

**Q: Will this reduce 240 volts to 110 volts**
A: Yes it will. But limited to 100 watts maximum power requirement. (It is not possible to run 'power hungry' 110 volt rated tools or equipment from this device)

### ⭐⭐⭐⭐⭐ Works well

Does what it says at a good price.

### ⭐ Very loud buzzing
*by G***H on 28 December 2025*

Unusable waste of money, buzzing loud first time it was plugged in.

### ⭐⭐⭐⭐⭐ Great quality transformer
*by K***E on 24 January 2016*

I bought this to use a Waterpik that I purchased in Canada. I'd tried to plug it into the bathroom socket, but it wasn't quite powerful enough for the Waterpik to work properly. So I bought this. Transformers have really come a long way since I last had one in the 1990s. They used to be big ugly boxes then, and they made a 'boom' noise when they were switched on. This one is fantastic and really showcases how far we've come since then. It has a nice long cable, so can act as an extension lead too. I think the cable is well over 1m long. There's no need to switch it on either, just plug it into the wall and plug your US product into it, and you're good to go. It's quite heavy, but still fairly small. I carried it around in a rucksack when I went travelling and it wasn't a bother. I's say it weighs about the same as a bottle of water, and it's about the size of a small grapefruit. It was good value at less than £15, and I think the quality is good enough that it will last a long time.
