I am looking to buy some equipment such as TVs and sound systems from the US. The problem is that in my country (Grenada) they use 220~ volts, and the US uses 110 volts. I could use a transformer for 110~ volts, but transformers use a lot more current compared to directly connecting to 220v.
I am wondering if modern TVs, sound systems, etc come with dual voltage, such as the chargers for laptops, so it can be connected to either 100-240v.
