VTUS-500

I purchased the Yinleader 500 W voltage converter to use devices rated for 110 V while traveling to areas with 220 V outlets. The setup was straightforward, and the unit feels solid and well-built. It handles small to medium electronics like chargers, lamps, and small appliances without issues. It stayed cool during use, and the voltage conversion is consistent. However, it’s important to check the wattage of your device—this 500 W converter is not suitable for high-power appliances like hair dryers or heaters. Pros: Solid build quality Easy to use Handles small and medium devices reliably Converts both 110 V → 220 V and 220 V → 110 V Cons: Not suitable for high-wattage devices Slight hum during operation Conclusion: A dependable converter for small to medium electronics. Works well as long as you respect the wattage limits, making it a practical option for travel or international use.

Handy. Saves me the trouble of getting an expensive electrician. Works well when renting too. I have a juicer that uses 220. I dont have a plug from the breaker with 220. This helps me to use my appliance. It helps to convert from 110 to 220 that the juicer needs.

I purchased a product from China directly and it needed this transformer to operate because it didn't have a switch for US voltage. It's been working perfectly with no issues. Seemed well made, rocker switch is solid, doesn't make any humming noise and powers the equipment. Came packaged very well. Everything is good, no complaints.

This is an awesome toroidal autotransformer that can produce 120/240V split phase from an isolated 240V input. Just set the switch to 220 and use the transformer’s center tap as the load neutral, which can be bonded to ground potential. You will need to determine which output socket prong is connected to the center tap. On my unit it was the ‘hot’ side of the 120V outlet, so that’s my neutral. It could have been either side. I’m not using that outlet as a 120V outlet in this application, just connecting that one lead as the neutral in my output and having L1-L2 connected to the input of this unit and connected to the 240V load in parallel. I do that because I’m drawing enough current with this load to pop the (5A?) input breaker on this unit if I use the 240V universal outlet for that instead of paralleling on the input. My application is to use a $150 12VDC to 230VAC inverter as a generator input to a hybrid solar battery system I had installed for my house. In this system the main inverter keeps the split phase load balanced, so all this unit needs to do is bias (center tap) the backup inverter output to the system neutral so it is a valid generator input. This autotransformer can do that since the 230 from the inverter is isolated and would normally just float if not center-tapped to a neutral. The main inverter protects the generator input from imbalance in the split phase but it can’t protect from inductive load spikes like motor starts, so I am adding a slow-start device (current limiter) to any motors over 1/3hp that may run off of this. With this inverter supplying the generator input we can use either our Prius Prime or our Rav4 Prime to provide backup power in an extended grid outage. The Prius especially is a nice backup generator because the engine is so quiet and efficient, and only turns on for about one minute out of 15, using the traction battery in between. Also if we started the outage with a full battery the engine doesn’t turn on at all for the first 8 hours. My unit arrived with a loose central mounting bolt allowing the transformer to flop around in the case, so I opened it up and tightened the bolt. Minus one star. While I had the case open I verified that the wiring connections matched schematically what I expected. This setup has worked well in over twelve hours of testing. I bought this low rated unit because I want to minimize the size, weight and losses in the transformer and any unbalanced 120V loads are handled by the main Inverter. If you want to have flexibility in your 120V loads, get the transformer that is rated for the highest 120V load you want to support.

took it out of the country to a place that required the conversion and this worked great. no issues. it will add some weight to your luggage though

Good product, It is a little bit heavy, but easy to use, I use it to transformer my power from 220 to 110, and even I spend 1 hour of the machine, it not get too hot at all, and I did not hear any sound from machine. The customer service also quick, if you have any questions, just email them and they will quickly respond back to me. So far I have this machine for 2 years already. Worth of the money

I didn’t used it after receiving. Today I tried and it is not working. It was good when I connected to electric. But after i connect a hitter fan, immediately it is not working. I used 110 -120 voltage options for getting stable voltage.

good for home use .it get over heat on continuous use

Toujours aussi fiable , j en suis rendue à mon 3ème de différents puissances. À acheter les yeux fermées

Muy bueno disipador calor

Quality... absolutely no question. Product as described. Fast delivery.

Purchased to attach a Bang and Olufsen Beosound 2500 to. It is heavy and feels expensive. It works perfect and I am very pleased with this order.

Creo los botones de voltajes estan invertidos. Me gustaria contactar con el proveedor. El equipo para lo que lo comprè es 220V y cuando lo pongo en 220 la licuadora no tiene suficiente potencia…. Y si lo pongo en 110V si tiene potencia. Para saber……..
