## Questions & Answers

**Q: What are the dimensions of the ST-500?**
A: Dimensions - 120mm wide x 155mm long x 105mm high.

**Q: I have just purchased a sewing machine from the US with a 2pin-plug (one pin bigger than the other) does this converter output hole fit?**
A: I have been using a US electrical box over here every day for about nine months. The Goldsource transformer is both safe and reliable. It has a bit of a design fault, in that the UK 3pin socket on the front of the transformer cannot be used if you have the two-pin USA socket in use at the same time. The problem is not electrical, but the UK and USA plugs bump into each other if they are both plugged in at the same time. It's a good transformer for the price. Recommended.

**Q: Can i charge my wife's mobility scooter while on holiday in the usa using this converter ???**
A: You need to inform us how many Watts or Amps the mobility scooter charger needs. This is a 500W maximum converter it cannot provide more power than that.

**Q: Hi there, i have studio monitior speakers from the us, watts for the pair are 250 watts rms/500 watts peak120v 60hz.will the be ok or a600 watts conv?**
A: I don't think your Monitor speakers would be powered directly from the Mains would they? That is to say, the speakers don't have a USA 2 pin power plug on the end of a power cord going into the back of the speakers do they?
The power OUTPUT of all speakers is given in "Watts RMS (Root Mean Square) rather than "Average" or "Peak" power handling, so this equates to a continuous maximum value. So, your 250 Watt RMS speakers would be suitable to be connected to a power amplifier of anything between around 150 to 250 Watts RMS output.
The figure for the speaker output is to give you a guide as to the power suitability of the Amp you are going to power the speakers with. So, for example, if you bought a 500W RMS Amp and turned the volume up to full power output, you would certainly blow your speakers to bits! (Very expensive repair job!!!) 
So, the question you need to answer is how much power does your AMPLIFIER need? There's usually details about this in the Customer's Service & Specifications booklet sold with the amplifier. If you don't have that, sometimes the details are shown on the box. If you don't have the box it was sold in, try looking on the back panel of the Amp - you may see details such as those you mentioned in your question, like: 120V (60Hz) plus a value for the power consumption, in Watts. If that's not shown, you could check the value of the fuse if there is one screwed into the back panel. Sometimes these are 2, 3 or maximum 5 Amps. That way, you can work out the maximum power yourself by applying the formula P = VI (Watts) For example Power = 120 (Volts) x 3 (Amps) = 360 Watts.
It's ALWAYS best to  buy a step UP/DOWN transformer that is rated slightly above the power rating of your Amp. So, lets say your Amp is 120 Watts, then DON'T buy a 100 Watt transformer otherwise it will overheat and burn out. Buy the next size up, such as a 150 or 200 Watt transformer.
Hope this helps...

## Customer Reviews

### ⭐⭐⭐⭐⭐ Simple and well built device.
*by D***B on 29 April 2016*

Reliable and easy to use product comes with useful advice sheet for those not familiar with electrical devices.Used many times as step down for pretty powerful (450W ) USA kitchen device in overseas territory with UK standard style power supply I.e. 240V.Solid well constructed device and comes with 3 fuses although I haven't needed to use the spares.Seller also very helpful regarding product query. Full marks for both the item and the seller.

### ⭐⭐⭐ Works but noisy
*by B***S on 25 October 2018*

It works fine, but it is very noisy. I have couple of others that Ibought in Canada that are much quieter. Fine for kitchen equipment etc, but for stereos not so good.

### ⭐⭐⭐⭐ Amazing but the smell
*by M***B on 2 June 2017*

It is wonderfull and works well. The smell however was something to get used to. Not sure why it has to smell that bad but perhaps there is sensible explanation. The smell went away after good few weeks in airy place.
