TESSAN Voltage Converter Review: 220V to 110V with USB-C for European Travel

Introduction

If you’re planning a trip from the United States to Europe, you already know the challenge: your 110V hair dryer, electric razor, or phone charger won’t work on Europe’s 220V system without the right gear. A simple plug adapter won’t cut it for high-wattage devices — you need a voltage converter that actually steps down the power.

TESSAN, a brand well-known among frequent travelers, offers two closely related models designed specifically for US travelers heading to Europe and other regions. Both combine voltage conversion (step-down from 220V to 110V) with universal plug compatibility and USB charging. In this review, we’ll look at what each model offers, where they shine, and which traveler should pick which.

Key Features

Both TESSAN converters share a core set of capabilities, but differ in plug coverage and port layout. Here’s a side-by-side overview:

Both models are step-down transformers, meaning they convert 220V input down to 110V output for your US appliances. They also function as universal travel adapters, so you can plug them into wall sockets across Europe, the UK, Australia, Italy, South Africa, and more — depending on the model you choose.

What I Like

True voltage conversion, not just a plug adapter. Many travel adapters simply change the plug shape and pass through whatever voltage is on the wall. That works for dual-voltage devices (laptops, phone chargers) but will destroy single-voltage 110V appliances. TESSAN’s converters actually step down the voltage, making them safe for things like hair dryers, electric shavers, and small kitchen appliances rated for 110V only.

USB-C is included. Both models feature one USB-C port alongside three standard USB-A ports. That’s a practical touch for 2024/2025 travelers who carry a mix of older cables and newer USB-C devices. You can charge a phone, earbuds, a power bank, and a tablet simultaneously without needing extra wall warts.

Multiple AC outlets. The first model (B0GFCHL6KK) gives you three AC outlets, while the second (B0FCLQ2HQL) offers two. Either way, you have enough sockets to power a hair tool, a CPAP machine, or a camera battery charger alongside your USB devices. That’s more flexible than most single-outlet converters.

Broad plug coverage. The first model includes plugs for Europe, the UK, Australia, Italy, and South Africa. The second model covers Type C, G, D, I, and L sockets — effectively the same regions but with different labeling. This means you can use the same converter across multiple countries on a single trip without swapping adapters.

Solid ratings and review volume. With a 4.5-star average from over 300 reviews and a 4.4-star average from over 1,100 reviews, both models have been tested by a meaningful number of real travelers. That’s reassuring for a product category where reliability matters.

Honest Caveats

230W max power — not for high-wattage appliances. The step-down transformer is rated for 230W maximum. That’s enough for most small electronics, phone chargers, and even some travel hair dryers. But it will not power a full-size 1500W hair dryer, a space heater, or a clothes steamer. If you need to run a high-wattage device, you’ll need a heavier converter. Check the wattage rating on your appliance before buying.

Not a universal voltage adapter for all devices. Some modern electronics (laptops, phone chargers, camera battery chargers) are dual-voltage and work on 110V or 220V without a converter. For those devices, you only need a simple plug adapter — not this converter. Using a step-down transformer on dual-voltage gear is safe but unnecessary, and adds bulk to your bag.

Bulk and weight. Because these are step-down transformers (not just adapters), they are physically larger and heavier than a simple plug adapter. They’re designed for carry-on luggage, but they’re not pocket-sized. If you’re a minimalist packer who only carries dual-voltage electronics, a smaller adapter may suit you better.

Plug compatibility requires attention. While the included plug heads cover many countries, no single model covers every socket type in the world. Check the specific plug types for your destination before you travel. For example, the second model includes Type D and Type L plugs, which are used in India and parts of South America — but the first model does not include those.

Who It’s For / Who It’s NOT For

Who it’s for:

• US travelers visiting Europe, the UK, Australia, Italy, South Africa, or other regions with 220V power
• Anyone who needs to run a 110V-only appliance (hair dryer, electric razor, CPAP machine, small fan) overseas
• Travelers who want to charge multiple USB devices (phones, tablets, earbuds) from a single outlet
• People who prefer a single device that combines voltage conversion and plug adaptation

Who it’s NOT for:

• Travelers who only carry dual-voltage electronics (laptops, phone chargers) — you’re better off with a lighter, cheaper plug adapter
• Anyone needing to power a high-wattage appliance (full-size hair dryer, space heater, kettle) — these converters max out at 230W
• Minimalist or ultralight packers who prioritize small size over versatility
• Travelers going to countries with socket types not covered by the included plug heads (check the list before buying)

Verdict

TESSAN’s voltage converters fill a specific and important niche: they let US travelers safely use 110V appliances in 220V countries, while also providing USB charging and multiple AC outlets. Both models are well-rated, reasonably priced, and cover a broad range of international plug types.

The choice between the two comes down to your needs. If you want three AC outlets and plugs for South Africa and Italy specifically, the first model (B0GFCHL6KK, ~$42.99) is the better pick. If you prefer a slightly lower price and need Type D or Type L plugs for India or parts of South America, the second model (B0FCLQ2HQL, ~$40.99) is a strong alternative.

Neither is perfect for every traveler — the 230W power limit is real, and the bulk is noticeable compared to a simple adapter. But for the right user, these converters are a reliable, practical solution for international travel with US appliances.
