The 100W GaN Universal Travel Adapter by TESSAN is a versatile and practical choice for travelers, especially those heading to Thailand. It supports voltage from 100V to 240V, making it compatible with the electrical systems in over 220 countries, including Thailand. This adapter is equipped with a range of plug types (C, G, A, I), ensuring that you can connect your devices no matter where you are.

The 100W USB-C port provides fast charging for your devices, and the additional four USB ports (3 USB-C and 2 USB-A) allow you to charge multiple gadgets simultaneously. The compact and lightweight design (weighing only 0.43lb) makes it easy to carry in your suitcase, backpack, or handbag, a great feature for frequent travelers. However, it is important to note that this adapter does not include surge protection, which might be a concern in areas with unstable power supply.

Additionally, it only works with wide voltage devices, so it's essential to check the compatibility of your high-power appliances like hair dryers and curling irons. The safety features, including double fuses and dynamic temperature sensors, add an extra layer of security, ensuring your devices don't overheat during extended use. This travel adapter is particularly suitable for travelers needing to charge multiple devices while on the go.

The TESSAN 2 Prong to 3 Prong Adapter stands out as a versatile travel converter designed for use in Thailand and other countries. Its key strength lies in its ability to convert a single Type A socket into four outlets and three USB ports, allowing you to charge up to seven devices simultaneously without blocking other plugs. This makes it perfect for travelers needing to charge multiple gadgets at once, such as smartphones, tablets, and earphones.

The compact size (3.15 x 2.24 x 1.18 inches and weighing just 3.4 ounces) makes it highly portable, easily fitting into your pocket or suitcase without taking up much space. Additionally, the dual USB A ports and a USB C port provide a range of charging options, detecting the optimal charging speed for your devices.

This adapter is designed for devices that are compatible with voltage ranges of 100V to 250V. If you plan to use high-wattage items such as hair dryers or straighteners, ensure they are also dual voltage, as this adapter does not convert voltage. The absence of built-in surge protection could leave your devices vulnerable in case of voltage spikes, so it's important to consider this when using sensitive electronic devices.

The EPICKA Universal Travel Adapter is a compact and lightweight option that fits well in travel bags, making it convenient for trips to Thailand and many other countries. It supports plug types compatible with over 200 places, including European and Asian countries, which covers Thailand’s plug standards. The adapter handles input voltages of 220V AC, matching Thailand’s electrical system, but it does not convert voltage, so you must ensure your devices support 220V to avoid damage.

Its wattage capacity reaches up to 1100W at 110V and 2400W at 240V, which is good for charging common electronics like phones, tablets, and laptops, but it’s not suitable for high-power devices such as hair dryers or curling irons. You can charge up to six devices at once thanks to multiple USB-A and USB-C ports plus an AC socket, which is handy when traveling with multiple gadgets. Safety is well addressed with built-in fuses, safety shutters, and certifications like CE and FCC, giving you confidence in its reliability.

A minor downside is the lack of voltage conversion, so extra caution is needed with some appliances. Also, it excludes some countries like South Africa and India, but for Thailand travelers, it covers the plug types needed. This adapter balances portability, broad compatibility, multiple charging options, and safety, making it a solid choice for most travelers heading to Thailand who want to keep all their devices powered up safely.
