Seems to work, but appears to make 240 voltage on both legs, I bought it hoping to be able to power a well and other appliances

Excellent 110/220 or 220/110 Transformer

This is nice efficient step up / step down transformer. It's quite efficient because it employs a large toroidal transformer to translate the voltage and current. Just remember: A practical conversion factor is 90 percent, so 5KW at 110 volts is 45 Amps, so it would produce 220 volts at 22 Amps, but 90 percent rule means more like 220 volts at 20 Amps. I bought this transformer to step up my voltage from my VEVOR 3600 Watt Pure Sine Wave Inverter because I want to have a portable source for both 120 VAC and 220 VAC. The 3.6 KW is 120 VAC at 29 Amps, But realistically I wouldn't press it beyond 25 Amps. So the transformer should output 220- VAC, 14.5 Amps, But 90 percent means it would be more like 12 or 13 Amps. I haven't even come close to that kind of load, but one has to plan ahead these days. This Transformer cost a lot less than buying a separate 12-Volt to 220 Volt Pure Sine Wave Inverter, and my 110 Volt Inverter was VEVOR-priced and easy to buy. It cost as much for the 12-volt cables (300 Amps Rated) as it did for the Inverter! But, with this Transformer, I'm now equipped to have mobile power for anything, and at a very reasonable cost.

Very good for the price. If it had a digital display, it's just more nice, but analog works fine...................

Works great

Works great

Fun stuff

Package was nice and solid. Quality wise it is pretty good. It has straightforward usage, little LCD is useful for precise setting.

Excellent

Good stuff

Great transformer

Great transformer. Good quality for the money. I purchased it to power my Guitar amplifier which is 220 volt. Has the European plug and Universal plug as well as Our American plugs.

Works like a charm

Converter works well converting 110V to 220V for my european kitchen appliances (up to 2500 W). Easy to use - just plug and play

Solid converter

I bought this to run a 2400 watt 240V pump from a 120V solar inverter. It works great, and handles the load with no problem. The only trouble I had was the included fuse limited the load to 2400W.

Excellent for the price

At this price, you can't beat it. The digital voltage display is nice, and accuracy is ok for an A/C RMS value (~ +/- 10%), but you may need to connect a more accurate voltmeter. (But since the A/C is normally converted to D/C, the regulator does not care about the 10%.)

Great

Good ,good.

i was wrong about vevor

Vevor has become my go to place to buy what ever i need ,they have a huge selection of tools and other goods

nice product

good transformer
