Question: For how long can I keep this transformer plugged in?  The little one I have now, I can only use for 1 hour at a time.
Document: I got this to use with some small appliances while I'm studying in Europe. At first this thing was completely silent. After a couple of weeks however, it started to make some noise. If I leave it on too long, or absentmindedly use it as a footrest it gets really REALLY loud.Also, a helpful warning for anyone using this, there are two outlets on the transformer, one for 120v and the other for 220v. Always make sure you're plugging your appliances into the right one.
It's a good quality converter. Heavy-duty and durable. But this one is a little too heavy and not so portable. I will definitely recommend this transformer.
I ordered this one after reading some of the reviews on most transformer. Its a little more pricy then some, but it seems to be worth it. Arrived here just fine, had a bit of a paint smell, but that disappeared after a day or so.No problems with it what so ever.
I bought this Transformer almost 4 years ago. It was a piece of junk. I plugged it in and it wouldn't work. I called the company and sent it back to them (paid shipping myself). They later returned it back to me telling me they are sending a new one but they were clearly lieing as I could see that it was the exact same one (from the way I had packed). TERRIBLE customer service. They were very rude in subsequent calls.
I am in Afghanistan and using this Transformer to step down the power so I can use my American products. I have been using this for a week now with no problems. We have one in the office that powers our priinters and microwave too.
It does what it says. Instructions are pretty crappy but the use is pretty straight forward.The built quality is good. It's on the heavy side.It looks like it wil work really good in the long run.Just be sure to never connect appliances that consume more power than this transformer can deliver (1000 watts).This is the major reason most people blow the fuse or in worst case scenarios, the appliance and/or the transformer.Good Luck!
Got here on time and does what it's supposed to do. Im very happy with it and did not have any problems so far. I use it for my 1000W espresso machine 220V to 110V.
Well am in Nigeria and bought this item over 6months ago and I must say,since then I have helped friends get 4 more.I don't know what some say about the noise,which only occurs when there is a drop in current.I guess am Lucky.Well its a great product.I don't use it all the time but still there aint no problem with this device.its highly recommendable.
First of all the transformer is noiseless, I have turned ON all at the same time with no issues: 47LG LE5500 led tv+ Ps3 slim + Toshiba HD DVD + Denon AVR-391 + Pioneer SW-8 Subwoofer and a lava lamp.Highly recommended!All the components are 110V but now are working in a 220V country.
I am using the transformer as step-up from 110V to European 220V 1 kW heater. Even I run it continually, there are no hick-ups whatsoever. Absolutely silent and cool. I could not be happier with it.
Answer: I can keep mine on permanently
