Bronson++ VT 300 (300 Watt) 220V to 110V Voltage Converter, use 300W US devices in Europe - Step Up Down Transformer - 110 USA to 220-240 EU-UK volt outputs

Bought this for a 110v device that was made in the 1990s in Japan. It worked a treat, and helpfully came with several spare fuses, which was useful because I did blow two of them on first use because I wasn't entirely clear on quite how to use it. Sadly I have no more fuses for it now but hopefully I can buy some from somewhere. The user manual is a little vague if you're not entirely sure what you are doing, but I got there on the 3rd try and once I did, it worked a treat. The device itself is really solid and fairly compact. Very happy with it.

Seems to work well enough. The metal construction makes me feel a bit more confident that it won't melt or suddenly explode, and it's fairly compact. It does make a low humming sound, but this is only audible from very close by. I'm nowhere near max load, so I can't comment on how it handles that, but my unit never gets more than warm to the touch (actually I measured it, it was 35°C). Although not shown in the image, the power lead is a fair length, around 60cm long. I will be using it extensively, and if this review remains as is, you can assume that it hasn't blown up or otherwise failed yet.

This is a review of the 200W Transformer. First of all please be aware that this is a relatively low power transformer and although rated at 200W the instructions say that for 'extended' use, the load should be kept below 60% (120W). To put that into context, this transformer will be fine for charging a toothbrush, camera, phone, Tablet and maybe even power a Nintendo Wii or laptop. It will not allow you run kettles, irons, hairdryers, coffee makers, hair straighteners, Laser printers or anything else that involves heat or motors. This transformer is slightly different to some other devices around in that it can be used as either a step-down or step up transformer. In other words you can use it in the UK to power something that you bought in (say) America or you could use in America to power something that is designed to only work on the UK Voltage. How it operates is determined by a 'jumper' at the back of the unit which is used to select the input voltage. By default, it is set for 240V which is the typical voltage in the UK. In this mode, it will output about 110V from the US style socket on the front of the unit. If you wanted to use it in America to power a UK device then you would need to set the jumper on the back to 110V and then use a normal USA to UK adaptor to connect the transformer to the US mains and then plug your UK device into the UK mains socket on the front. When I unpacked it, the first thing I noticed was strong smell of fumes, similar to that sometimes noticed in dry cleaners. This passed after a few days in the open but it was initially quite pungent and I imagine could give some people a headache in a confined space. This was why I only gave 4 stars. The weight is 1.9Kg so it is going to take a chunk out of your baggage allowance if you are thinking of taking it on holiday. I would say that really this transformer is intended to power something in the UK that is designed for the US voltage (like a Christmas decoration). In my case the transformer worked perfectly out of the box. Running it from the UK mains for 12 hours, the output voltage was 111V. There is a very quiet hum which I could only hear by putting my ear within a few inches of the transformer however, I expect it would get noisier when fully loaded. Overall, if you want to power something that is designed for America or Japan while you are in the UK AND the power requirement is less than 120W then this transformer will do the job.

Perfect item for converting USA based products at 110v for use in the UK at 240v. Need to ensure that the products you intend to use it with are at the correct wattage rating as there is a maximum wattage with this product (for individual and/or continuous use). The product is made with differing wattage ratings so you can select the appropriate model for your needs. Can be used to convert voltage both ways so is good for USA and UK use.

Doesn't work at all. The red LED light does not turn on when plugged in and turned on. The 240v output works, the 110v output has zero power. Going to have to return this.

Bought this to step down UK voltage to US for a gadget only available at 110V. So far it works a treat and everything works as it should.

Brought 3000W to power a 1400W waffle iron (as you must double the watts). Works a treat. Tad heavy but no smell, no buzzing, works fine

So solid, works great no problems
