LVYUAN 3000 Watt Voltage Converter Transformer Heavy Duty Step Up/Down AC 110V/120V/220V/240V Power Converter with 3 US Outlets, 3 Universal Outlets, Resettable Circuit Breaker Protection

works great

UPDATE: seller replaced item and it's working now. Will update if it fails again. way under specced. This worked fine for a few weeks, but now it fails after about 30 minutes of sustaining a 130 watt load (a small hvac blower). Yes, the product listing states you should size up 3x for running a fan motor, which we did. E.G. they say 1500 watts rating is required for a 500 watt motor. But our motor only draws 130 watts. You can do the math, but that's way less than 500 watts. Also, it fails while the fan is running, not during start-up, when the 3x extra capacity is supposedly required.

Works great.

Great quality, function well. A little bit heavy.

This is a great product!

Me sorprendió la entrega, fue bastante rápido, habían estimado que fuera en 1 semana, y me llegó en la mitad de tiempo, no me lo esperaba, justo tuve una jornada larga el día anterior y no pude contestar las llamadas, pero fueron temprano a mi casa y me despertaron para avisarme que había un pedido, agradezco que haya sido mucho antes, lo iré probando para ver que tal va, pero hasta ahora todo bien, además otro punto fuerte es que viene bien cuidado el producto, las piezas de Tecnopor que lo recubren están bien solidas y amortiguadoras, gracias.

Unit was incorrectly wired. Prior to using checked the 110 volt sockets with a cheap 3 light tester. Was plugged into and the switch was set for 110 Volt input. When the power switch was on the tester indicated reverse polarity, when turned off it showed Hot and Ground reversed. The Hot Ground reverse is a false reading due to a broken neutral. Pulled out a multimeter and verified the 110 volt neutral and hot were reversed. More importantly the 230 volt socket tested 120 on both the Active and Neutral regardless of the power switch being On or Off. These results had me suspect a reverse polarity issue with the power switch wired to the neutral. Confirmed this by supplying power an extension cord with intentionally wiring the female end with the Hot and Neutral reversed. This immediately resolved the issue. The terminals on both the 110 and 230 volt outlets no longer had voltage when the power switch was off. With the power switch On the sockets tested correctly, correct polarity on the 110 volts and only had 230 volts on the Active/Hot wire. Contacted support from the Amazon site as per the instructions. Within 5 minutes the chat apologized for the issue and offered refund options. Gave a separate 5 star review on the vendor feedback for the quick transaction. The unit itself seemed well constructed, liked the unit. Needless to say I opened the case and confirmed the neutral was wired to the power switch. Ended up swapping the input Hot and Neutral by re-soldering them at the input connector. Unit now test and operates normally with the original provided power cord. For those wondering I had verified the power source (wall outlet) for correct polarity. In the end have to give it a 1 star review as most users probably would not have the ability to test the unit prior to using it. Otherwise like the construction and very minimal noise from the unit. Nearly silent operation, have to put an ear next to the case to hear any transformer hum. If wasn't for the wiring issue would have given a 4 or 5 star review! The attached pics show initial power On and power Off. Last pic was post modification.

Era lo que esperaba. Llego bien rápido.
