However, I decided to take a chance on this model:- Yinleader 500W Voltage Transformer... the wattage is 500 but, this is where a lot of buyers make the mistake thinking, it can be used upto the max 500 watts ! Not so; and one needs to keep in mind this is the design max INPUT TO LOAD rating when it steps down from 240 Volt to 120 Volt, where the actual max load would in reality be, around 300 to 350 max for this model autotransformer... they need to be used under the design wattage, otherwise they will over heat, and maybe; a much worse fault condition could occur to damage the device your connected too. At this point, you should know there are two types of step-down voltage products out there. First, the much cheaper ones are CONVERTERS, they are electronic in design and step-down the voltage by switching the mains input ON and OFF at the supply 50 or 60 Herts rate, or dedicated oscillator higher rate; it's the same design concept as these DC 5 Volt USB wall socket plugs. The AUTOTRANSFORMER, is an actual coil wound transformer design; with one input winding and a half way taped voltage winding to provide the half voltage output; that's why these are more pricey and heavy in weight... these in my personal opinion are the more reliable unit to buy, nothing to fail other than the over loading of the transformer, as I have outline below. The Yinleader 500W Voltage Transformer has a cut-out on the back, that is a good feature to limit the transformer winding load, if you go over 500 Watts it should cut off; I have not tried to see if it would trip-off ? But if it does, you will need to re-set it after a sort period when cooled down; but at that point you should realise your overloading the autotransformer... it's stressed that a load for this model needs to be no more than 350 Watts and that's pushing it. If in any doubt on the loading, you can do a very simple check; just feel the base of the unit, it should not be hotter than what you can touch and keep your hand on the base... if it's too hot to touch, remove the input supply and let it cool down; then review the loading of the device you have it connected to, and find a much higher Wattage Autotransformer. I would class this transformer as medium wattage, for most light loads like a domestic hair dryer or tongs, a vintage valve radio, standard Filament Lamp and so-on; light power loading. NOT Clothes Irons, Smoothie Mixers, or Food Processors... always check the appliance Wattage First, before using this autotransformer. Review: Top domestic transformer - Its big but its bountiful - Great transfo. Its sturdy and works well with the devices I purchased it for. It uses old school technology (wound coils) and thus wouldn't be a unit you would put in a backpack for a weekend. That said... car camping as opposed to hike-camping would be fine!. ## Features - We provide you a safe, dependable, stable, cost-effective & easy solution to converting voltages from 240 volts down to 110 volts in UK.

The over heating could be due the item of equipment it is suppling power to having a higher Watt then 500 Watt which is the limit of the Transformer.. If this is so or the Watts of of the equipment are close to 500 Watts you need a Step down Transformer of much higher Watts capacity may be double the Watts of you equipment. The terrible smell is the Transformer burning up inside. Please do not continue using it. **Q: hi can I use Japanese appliances in the uk with this?** A: If appliances are 220/240 volts, 110/120 volts yes. **Q: Can this work for a canadian tv that i’ve brought to the u.k.** A: If your tv is 110/120v or 220/240v AC YES. **Q: I have a 110/120V cup turning device. Can this transformer run for up to 12hours + at a time?** A: I'd say yes it could run without issue for 12 hours. It does not involve the heavy currents of an arc welder which will have a duty cycle of minutes rather than hours in some cases. The unit I purchased was to run the heating element of a water bed, so is switched on 24/7. Naturally the element, being thermostatically controlled, it doesn't continually draw current, but will for extended periods in cold weather. The element is rated at 300w and the transformer puts out 500w, that's what is important. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well Built Design : Step-Down Autotransformer 240 to 120 Volt 500 Watts Rated For 350Watt Load Max *by B***S on 10 August 2023* Went searching through a lot of these step-down transformers, and converters; most of the reviews were not too promising, and had the tendency to put one off.

Its sturdy and works well with the devices I purchased it for. It uses old school technology (wound coils) and thus wouldn't be a unit you would put in a backpack for a weekend. That said... car camping as opposed to hike-camping would be fine!. ### ⭐⭐⭐⭐⭐ Yo leader 500W Voltage Transformer *by T***A on 2 June 2024* Like many others, I read reviews of many other transformers, and still wasn’t sure which to get. I wanted a transformer that could carry my 110V Purifier. I decided on this particular transformer because the 220/240V switch could take different plugs, not only the 3pin. Also, the transformer was a 500V one, so it should be able to take mid-range products, like my Purifier. I was pleasantly pleased at its effectiveness. It was a check the wattage, plug in, and play. That easy. My Purifier came into life, and purified! lol! ## Frequently Bought Together - Yinleader 500W Voltage Transformer, 220/240 Volts to 110/120V Step Up Step Down Voltage 500VA - C2G 80672 1.8m US Power Cable 18 AWG North American Power Cord ( NEMA 5-15P to IEC320C13) 6 Foot US Power Lead,Black - ABC Products USA United States America Canada C13 Kettle PC Computer Power Supply Adapter IEC Cord Mains Cable Lead Plug for Monitor, Printer, Photocopier, Screen, TV, Treadmill, Audio, Amp 1.8M Long --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/289379596-500w-voltage-transformer-220-240-volts-to-110-120v-step](https://www.desertcart.us/products/289379596-500w-voltage-transformer-220-240-volts-to-110-120v-step) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
