20,000 Watt Step Down Voltage Converter Transformer – Heavy Duty 220V to 110V Hardwired Power Converter for Overseas Use – Industrial Grade with Dual Voltage Support and 5-Year Warranty

Item came in damaged box.Thanks to Amazon double wrapping the boxes or unit would have been damaged for sure. Unit seems to work ok for now but only time will tell.I am using this to step up from 120 vac to 220 vac for a contemporary kitchen exhaust rangehood that was purchased in Europe. The rangehood consumes (according to manufacturer) 270 wattts of power. This transformer is 1000 watt so I should be good to go. Note: I just checked the voltages to see where they are at. My household voltage is at 123.7 Volts AC and the transformers pumping out 247 Volts AC ? On their wrinky dink owners (from China of course) manual they claim to USE at least 50% higher wattage transformer than your equipment required wattage. So this in my opinion is NOT a true 1000 watt transformer??? More like 500 watts tops? The chinese ALWAYS try to make their product sound better than what it is. Also this product does NOT have UL or ULC or CSA certification symbols on it??? This is very concerning? Good thing my exhaust fan doesnt exceed 300 watts total? Also, the instructions also tell you to "turn it off" when not in use so this is NOT a continuous use transformer? I will keep everyone posted of my findings and performance of this unit over time. Remember the formula AMP X VOLT = WATTS for example if an electrical razor draws for example 1Amp X 120 volts= 120 watts of power is needed UPDATE: Item still works great.Installed rangehood fan from Europe (220 Vac) fan uses close to 300 watts of power so picking a 1000 watt unit should NOT put any strain or stress on it. Transformer puts out 247 volts which is ok for European voltages. Still going strong Ill keep you updated! UPDATE: May 18/2016 transformer still going strong , exhaust fan still runs perfectly Great transformer upto now Recommend

I’ve been using this converter for over a year now, and it has been nothing short of exceptional. As someone who values consistent electrical output, this converter has exceeded my expectations. From day one, it has provided a stable and reliable performance without any surges, ensuring that my expensive equipment runs smoothly. Whether I’m using it for my home office equipment or other electronics, it has never let me down. The build quality is solid, and it feels like a durable piece of equipment that will last for years to come. One of the standout features for me is its ability to handle both step-up and step-down conversions seamlessly. This versatility has been incredibly useful, especially when dealing with different voltage requirements for various devices. Overall, I couldn’t be happier with this purchase.

It works well. I have had no issues. It's easy to use. No overheating.

I pick it up to power my video projector and home theatre in Europe. That is why I use the converter to connect to 220V 50Hz currency line my gears which take 110V 60Hz. I want to be sure that power (1000Wt) is enough to use that set I described (home theater - 530Wt and video projector - 350Wt). The only thing is the price which is a bit high for such devices.

I use this for my construction company in Africa (Ghana). It has been holding up for months now . Protects all my power tools perfectly. I don’t regret this purchase at all

The 3000W is not good for household use and the 5000W most definitely not. This appears to be a well-designed and well-intentioned product. It's quite light compared to similar competitors. However, the toroidal design means low losses and a VERY HIGH INRUSH CURRENT. So pay attention as here's the real issue and catch to this transformer & why it's NOT for household use...despite what you may read in couple positive reviews, do not buy/use this in household unless you have 35A main (house) circuit breaker and probably 25A circuit breakers inside house, as the initial surge spike is up to 32A, per the testing done by actual electricians because it kept blowing out power in the house. As a number of other reviewers posted, it will blow out power in entire house, and really blow out house power in a lot of houses, esp. the newer ones (built w/in past couple to 3 decades)...the 25A tri-phase main breaker outside the house (standard in majority of Europe now) that feeds into house grid will trip and you'll lose power to whole house until you reset...lots of fun I tell you. This transformer is really for industrial use. 15/16A breakers will trip inside the house for sure, and even if 40A sectional breaker on house circuit housing doesn't trip, the outer main feed 25A breaker will trip as this transformer load trips its treshold for any single phase. An industrial 16/20A circuit breaker inside the house won't trip, but then it's unsafe to use such in households, yet the main breaker outside will. If you don't have something like 32A main outside breaker and 25A breakers inside house, this isn't for you, and even then this might not be enough unless you also buy & install a current limiter, which is a resistor that is short-circuited after the current rises and which should be provided by the seller as a standard option because such an item is usually supplied with this type of transformer. However, the seller doesn't provide such an option, not does the seller even mention the high surges that this transformer experiences. Realistically, this is essentially false advertising as this item shouldn't even be sold without such cautions. If you don't want major issues, stick with non-toroidal transformers, such as Rockstone, which we had during previous time in Europe for 3 years in Belgium without any issues, even with some of the flux in Belgian grid.

I am overseas and was getting tired of not having enough power or outlets to power up my items. I was looking through various transformers and chose this one based on it's wattage and it's Amazon prime availability. There were a few cosmetic issues after first inspection. Those do no affect the performance one bit. I was able to plug every item i had in my room into this and still had more available outlets and power. I have had it about a week and keep it on constantly and have had no issues with over heating or tripping circuits. I have had a television, DVD player, game system, shop vac vacuum cleaner, 2 laptops, a cordless phone, all plugged in and operating at once with no issues. Great product. Received it very quickly. If you need a lot of power for a good price get this.

I installed a 3 phase induction motor w/VFD on my mill a while ago. At first I ran it with 120v, but ran slow. Then I ran a 240 line to the mill and things were peachy. The VFD I have will take anything from single phase 120, split or single phase 240, or 3 phase input and output 3 phase. The output voltage is determined by what it fed into it. I moved, and always intended on running 240 to the mill again, but I really didnt want to break walls open, so I considered a spindle motor upgrade that could take 120. After looking at the price of the project, decided on just getting a step up transformer to test. First test popped the GFCI (didnt know it was GFCI at the time). Not surprising, as thats a known issue with VFDs. Tested it on another outlet and the spindle motor runs like a champ.
