VEVOR Voltage Converter Transformer 3000W Heavy Duty Step Up/Down Transformer 110V to 220V Convert 220V to 110V US Outlet EU Outlet 5V with USB Port CE Approved

This transformer is dangerous and a fire hazard. I was having lots of issues with it tripping up my fuses until I found out that it does not abide to electrical standards. When you connect the multimeter to the Neutral connection and Ground, the reading should be 0 (Zero). However, it came up as 220V! Really, really bad. I even got shocked a couple of times because the neutral wire was live!!!! This transformer should be excluded from Amazon and from all online shopping. It will kill someone someday or catch a boat/house on fire.

Provato è perfettamente funzionante. Alimenta il mio impianto audio in maniera impeccabile ( alcune casse sono da 120v di importazione americana) e questo convertitore fa egregiamente il suo lavoro!!! Consigliato L acquisto

This lets me use my tools brought from the US in Finland

I've had so many problems with voltage converters I was nearly ready to give up. Prior to buying this, I had two others that stopped working within a month due to various reasons (both a high-end and budget). Not even taking this into account, this is still the superior converter of the three. It is a tad larger but not only is it the quietest, it produces virtually no heat on the outside at all. The other two both claimed to produce little to no heat but nearly burned the hand upon touch.

Working well
