## Questions & Answers

**Q: Is it 3 pin plug head and Will  it step down for a toddler ride-on car charger rating : 120V- 60Hz 0.12A**
A: It is a 3 point head but I don't know about stepping down for a ride on car I use it for a magic bullet (mixer).

**Q: will this work for a  US playstation in UK?**
A: I'm not certain but it worked for my appliance that I bought in Canada. Sorry not to be more helpful

**Q: Will this work for a u.s.a nintendo wii in the u.k?**
A: Depends on the voltage of the Wii.  The adapters take an 110v appliance and convert it to 240v, the British norm.  I use them for Christmas lights that we bought home and also for my sewing machine which I bought in the USA.

**Q: i have bought rusk str8t hair straightners they are 120v 60hz 300w. Would this converter be ok for the straightners?**
A: Mine melted when used for long periods to power Christmas lights @100 w. Better go to Maplins who sell a 120v 300w transformer. Best of all I think buy a 240v pair.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Fine for converting low power devices.
*by  on Reviewed in the United Kingdom 29 October 2020*

Satisfied with product. Only used it once so far to power vintage 8mm camcorder from the US. All worked fine, no problems. Solid build, but I would not reccomend for high power devices such as power tools etc.

### ⭐ Do not purchase! Fire hazard
*by  on Reviewed in the United Kingdom 29 April 2021*

2 mins into using this with my blow dryer brush on low i heard a popping sound. Smelt something burning and the dryer stopped!!! I quickly plugged out the converter and it was still popping and smoking... tried to capture it on video but it was faint. My room smells horrible and now my dryer is not working along with the converter plug... I am so disappointed as the reviews praised this but I should have spent a little more and got a unit that actually is safe and durable. If I could give zero star I would. Will be returning and would never recommend or repurchase!!!! Not safe at all.

### ⭐⭐⭐⭐⭐ Voltage adaptor
*by  on Reviewed in the United Kingdom 16 August 2025*

This step down voltage plug fit my socket well and is a good weight. Unfortunately I had to return as the item I bought this for did not work.
