BESTRANS 3000W Step Up Transformer 110v to 220v Converter, Heavy Duty Voltage Converter 110v-120v to 220v-240v with Dual Outlets, Overload Protection & Ultra-Quiet for Home Appliances, Grey Blue

Works like a charm

Works great, gets the job done.

I have been using it for 6 months and it has been flawless. Works well and power supply is very stable.

Doesn’t make any noise is easy to store but is way to heavy. I bought it because I brought my hair dryer from Europe and in America is different so it fixed my problem just fine

Bueno

We bought this because we bought a really good rice cooker in Korea and we knew all appliances in Korea were 220v but I thought it would be like most items who have a range of 100v-220v or something but it wasn't so need this converter. Works really well without being as bulky or loud as other transformers I've used in the past.

If you are looking for a converter，this is the one. Tried 3 other brands on amazon，they are not working at all except this one. My laundry machine saver！

I have it running a 1000W led light system, so I'm not really stressing it, but it stays cool, doesn't make noise and delivers the voltage I need, so I'm happy with it.

I used it to adapt a 220V Washer (UK plug with a fuse) to connect to a regular Canadian 15 amp receptacle and it worked great. I was a little nervous because the washer was rated for 1600 watts. I used a device to measure the wattage draw and ran different washer cycles - it didn’t go anywhere near 1600 watts. The highest was 1300 and that was only on a special cleaning cycle that uses an internal water heater.

I got a Dyson Hair Dryer from China and bought this in order to use it in Canada. It works very well; I don't have to spend money to get another Dyson in Canada. Very happy

… if ordering European appliances to use in NA Heavy so set it once where you want it used. Convenient power toggle of top surface of casing

The label on the device is not mentioning any certification.
