10 Best Voltage Converters 2026 in the United States

The Ceptics 2000W Travel Voltage Converter is designed primarily for travelers needing to use 110V devices in countries with 220V power supply, such as those in Europe, Asia, and Australia. It features a robust 2000W wattage capacity on one outlet, ideal for high-power devices like hair dryers (except certain brands like Dyson), and an additional 200W capacity on two separate outlets for smaller styling tools like curling irons or straighteners. This means you can safely use multiple beauty appliances at once without worrying about overload. The converter also includes four USB ports (three USB-A and one USB-C with Quick Charge 3.0), enabling you to charge up to six devices simultaneously, which is very handy for phones, electric toothbrushes, or other small electronics, matching charging speeds automatically.

Its input voltage is fixed at 220V, converting down to 110V output, which suits travelers going from 220V countries to devices designed for 110V. In terms of safety, it includes a quiet built-in fan to avoid overheating, and protections against surges, short circuits, and overcurrent, making it reliable for frequent use. The compact size and light weight (about 15 ounces) with a 5-foot cable add to its portability, though note that the product does not come with multiple country plug attachments included; these need to be purchased separately depending on your destination. It supports numerous plug types (A, B, C, E/F, G, I), covering a wide range of countries.

One drawback is that it won't work with certain electronics hair dryers like Dyson, so users should check compatibility beforehand. Considering its versatility, wattage capacity, and multiple device charging options, this converter is an excellent choice for travelers carrying multiple high-power and USB devices who travel to countries with 220V power sources and need a reliable step-down converter.

The TESSAN Universal Travel Adapter is a versatile voltage converter ideal for frequent international travelers. It can convert 220V to 110V, making it suitable for use in over 200 countries, including popular destinations like the UK, Europe, Australia, and many more.
