Review on 500 Watt Step Up and Down Voltage Converter Transformer with USB Charging Port, UK Power Adapter, AC 110 / 120 to 220 / 240 Volt and Vice Versa, 110V/120V/220V/240V Input Voltage - Pyle PVTC320U by Tim Springer

I had bought a 220V scale in India. I was looking for a safe and reliable product. Because it was connected to electricity. After a thorough search and reading many reviews. I have decided on a product from PYLE. The product is well put together and can be operated by anyone even without sufficient technical knowledge. When I turn on the power converter. The first thing that struck me was the quietness of the product. There is no transformer hum at all. This means that the transformer is mounted perfectly and you don't have to worry about the product overheating and loss of performance. And this product can be used anywhere in the world. The input voltage selector is already set to 110 V US. So you don't have to worry if you are in the US.
