10 Best Voltage Converters 2025 in the United States

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. One of its strong points is the ability to handle a range of devices, boasting a maximum wattage capacity of 2000W for household appliances and 200W for smaller electronics like laptops and smartphones. This makes it a flexible option for various charging needs while on the go.

Additionally, it offers 7 charging ports -- 3 AC outlets and 4 USB ports (including a USB-C). This allows you to charge multiple devices simultaneously, which is a significant advantage for travelers carrying multiple gadgets. In terms of portability, the adapter is compact and lightweight, easy to pack into your luggage or briefcase. Safety features like overheat, over-current, and short-circuit protection add peace of mind.

However, there are some limitations. The 2000W AC sockets are not compatible with low-wattage devices like electric shavers or toothbrushes, and the dual adapter socket does not convert voltage. It's crucial to check your devices' safety data sheets to ensure compatibility. Additionally, the fan, while ensuring the device stays cool, may produce some noise, which could be a minor inconvenience.

The Ceptics Travel Voltage Converter is designed for travelers who need to convert 220V electricity to 110V, making it particularly useful for appliances like curling irons and straighteners.

One of its standout features is the ability to charge six devices simultaneously, thanks to its multiple USB ports and fast charging capability, which allows for quick power-ups on the go.

Portability is another strong point; it's compact at 4.8x3.1x1 inches and weighs just 15 ounces, making it easy to pack in your luggage. The safety features, like surge protection and auto shut-off, provide peace of mind when using your devices abroad.

However, there are some drawbacks. While it handles various plug types (Types A, B, C, E/F, G, I), users may need to buy additional attachments for certain regions, which can add extra costs. Additionally, the wattage limit of 200W may restrict use with higher-powered devices, such as some kitchen appliances or hair dryers, which often exceed this threshold.

Safety is a strong point for this converter, as it is ETL certified and comes with protections against over-current, over-load, over-heat, and short-circuit, providing peace of mind during use.
