Mercury Stepdown voltage converter 230V - 110V 45W

I've had this step-down current converted for a couple of weeks now, and it's never shown any signs of failing, burning or made any loud noise. I've been using it with a 37 Watt air purifier, on and off, sometimes ensuring to not exceed 1 hour usage at a time, but occasionally forgetting about this restriction (read the description and don't use with high wattage appliances). The device does get warm, but reasonably so, like a phone charger. And it does work. How do I know? Well, when I bought my American purifier (120V), I initially plugged it in using an ordinary US to UK plug adapter. The purifier was then very fast/loud, even on the lowest setting, making me think it was broken. But since I started using this converter, the purifier has been working much more quietly/slowly, when expected to do so. It looks like getting twice the current made it work twice as fast, which was not how it was meant to be. Overall, I'm very happy with this product.

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.

All good

This is a step down voltage converter to go with my Toro ultra plus leaf blower because it is 110V not 230V because otherwise the voltage in this country it is 230V in the USA it is 110V and the Voltage would ruin the appliance. This is what you need to use american products you cannot use an ordinary adapter. But this converter is well worth the money if you don't want to ruin you're appliance. I will post a video of the converter when I use it TBC

Worked for around 5 mins, then got a vibrating noise coming from it , stopped working / cut out , with a strange smell coming from it , possibly overheated , only used on a small aquarium filter, sending back for refund,

Its okay it works fine but I didn't realise its only useful for 1 hour at the power rating that I need for my US device

The item works as labeled and is great value for its price. I noticed a couple of points that may discourage other buyers: - transformer hum is quite loud compared with other similar transformers I've used - output is stated as 45VA, but there's a clarification that it should be used over 30VA for more than an hour, I imagine that due to heating issues. I'm using it for a 25W device so it works ok in that case

Does what is says !! Excellent
