SIMRAN Step Down Transformer THG-500 - Transformer - AC 220/230 V - 500 Watt

Purchase for a hot water pump and didn’t want to run an electrical line I added an extra ground wire. 220 to 110v works great I was afraid It would be under sized the pump had no amp rating motor was one fifth hp.

The transformer is perfect for converting mains 230V AC to 115V AC. Because I stay in a 230V AC country, this device supplies my American and Japanese equipment that works with 115 AC. It is a real transformer with sinusoidal waveform. It should work fine in 220-240V countries to down convert to 110 - 120V I am confident there is no danger of damaging my equipment. I got the 500W model and that is good for devices consuming 1W - 400W in total. It however has a 600 ohm resistance between the primary and secondary earthing, but that is good for avoiding earth loops in audio and video devices.

This is a solid product, and is well-made. The cord and plug seem strong. I'll give an update when I return from India to let you know how things went.

I am an Officer on a cruise ship and needed a transformer for continuous use in my cabin to run my USA appliances such as small refrigerator . First unit arrived and was damaged during shipping. The unit was hit in the only place I believe could have been damaged, the fuse holder. Amazon immediately sent out a replacement unit and it works perfectly. Completely silent and more than enough to handle refrigerator, clock and electric toothbrush I have plugged in.

This transformer does a great job. I used it on a trip overseas with an air mattress I bought for my aunt as a gift. It worked great, we had no problems at all. If you're looking for a good powerful transformer for your item, this is the one. It is a bit bulky at around 7 lbs, but definitely worth taking it along and worth the extra money.

Before buying this one, trying to filter through all the reviews, my interpretation was that it will do its job, although there is a lack of quality control in the plant - at least when it comes to the solderings, coil integrity, have no means of testing now. I had one cold solder in mine, on the primary side. It works out of the box though, but I would advise to check it before you start using it. I am still in the US, but am running it redneck style after my 1500W step up transformer, just to check it. I do not know how hot the coil will run with a higher continuous load though, but I was only planning on using this for the smaller things, and bought a THG2000, for the larger loads. With the bulky weight, this would not be for air travel, but a couple in different sizes for a relocation is the best purpose for this design in my opinion.

You have to be kidding me! I found a 1600w step-down from Brookstone that is super light. This one is only 50w, which would've been fine, but Due to the fact that it weighs about 10-15lbs, I think not!! Not convenient for travel. Also, when I unpacked it, it was dented in (NOT good for electrical equipment, and it had a funny electrical smell. I wouldn't trust this thing with the cheapest appliance. This is going back.

Seems to work great after 3 months and looks like it is built very well. Easy to use, and pretty basic. We took a 220volt well pump, and dropped it down to 110 for a water softener because we had no neutral to get 110. I am happy with the product so far.
