10 Best Universal Travel Adapter For Vietnam 2025 in the United States

The TESSAN US to Europe Plug Adapter is designed for travelers heading to various European countries, making it a practical choice for those planning to visit Vietnam as well, given the adapter's versatility. One of its key strengths is the 7-in-1 functionality, which includes 4 AC outlets and 3 USB ports. This allows you to charge multiple devices simultaneously, perfect for tech-savvy travelers who carry several gadgets like phones, tablets, and laptops.

The dual USB ports can deliver a decent charging speed of up to 2.4A, while the USB-C port offers a faster 3A, which is great for quickly powering up your devices. Its compact and lightweight design makes it easy to pack, taking up minimal space in your luggage, which is especially beneficial for busy travelers.

However, there are some limitations to consider. This adapter does not function as a voltage converter, so it’s essential to ensure that your devices can operate on a voltage range of 100V to 250V. If your device only supports 110V or 125V, you will need an additional voltage converter, which could be an inconvenience. Also, it lacks surge protection, which may be a concern for sensitive electronics in areas with unstable power. Finally, while it’s well-suited for use in hotels and dorms, the absence of power cords means it may not be ideal for all situations, such as when you need to power devices from a distance. This adapter is particularly well-suited for budget travelers or those who need a lightweight and space-saving solution for charging their essentials while exploring Europe and potentially even Vietnam.

The TESSAN 140W GaN Universal Travel Adapter is designed for international travelers, making it a versatile choice for those heading to Vietnam and beyond. It supports plug types from over 200 countries, including Type A, C, G, and I, which makes it highly compatible for various destinations. One of its key strengths is its charging capability, featuring two USB-C ports that can deliver a total of 140W for fast charging, alongside an additional USB-A port. This means you can charge multiple devices like your phone and tablet simultaneously, which is a big plus when you're on the move.

The compact and lightweight design (only 0.62 lbs) adds to its portability, allowing it to fit easily into your bag without adding much weight. Its size makes it a practical travel companion for tourists and business travelers alike. With a double fuse safety feature, it also aims to protect your devices during use, which is crucial for peace of mind while traveling.

It’s important to note a few drawbacks. While the adapter is versatile, it does not include surge protection, which may leave your devices vulnerable to power spikes. Also, it works only on devices that support wide voltage (100V to 250V), meaning you cannot use it with high-wattage appliances like hair dryers unless they are dual voltage. This could limit its usefulness for some travelers who rely on such devices.

The TESSAN Universal Travel Adapter is a solid choice if you need a convenient way to plug your devices into outlets in Vietnam and many other countries. It supports six common plug types including Type C and Type G, which covers Vietnam and most popular travel destinations, making it versatile for international use. The adapter works with devices that run between 100V and 250V, so it’s compatible with most modern electronics—but it’s important to note it is not a voltage converter. This means it won’t change the electricity voltage, so devices like hair dryers or straighteners that need specific voltages might not be safe to use.

One of the adapter’s biggest strengths is its multiple USB ports. It has two USB-C ports, including one that can deliver fast charging at 45W, plus three USB-A ports that can charge several devices simultaneously, which is great for charging phones, tablets, and other small gadgets without needing extra chargers. The adapter is also compact and lightweight, easy to carry in your bag without adding bulk.

The adapter does not have built-in surge protection, which means it offers limited defense against sudden electrical spikes. It does have a double 10A fuse and safety shutters to help protect your devices, but if you’re in an area with unstable power, you might want to be cautious. The build quality is decent for travel use, but this adapter is designed mainly for convenience and portability rather than heavy-duty or rough use. This TESSAN adapter is ideal for travelers looking for a reliable, lightweight adapter with multiple USB ports for charging various devices on the go, provided they use electronics compatible with Vietnam’s power standards and understand it won’t convert voltage or offer advanced surge protection.
