The TESSAN US to Japan Plug Adapter is designed for travelers heading to Japan and other countries using Type A plugs, including Mexico, Canada, and the Philippines. It includes two adapters, each with 4 AC outlets, 1 USB-C, and 2 USB-A ports, allowing you to charge up to 7 devices simultaneously. This can be particularly useful for families or individuals with multiple electronics such as smartphones, earphones, and laptops.

The USB-C port supports quick charging (15W), which is a great plus for those needing speedy power-ups. However, keep in mind that this adapter does not convert voltage. Ensure your devices support the local voltage (100V-250V) to avoid damage. The compact size (3.15 × 2.24 × 2.25 inches) and lightweight design (3.46 ounces) make it easy to carry, fitting well into travel bags.

The absence of surge protection means it is also suitable for cruise ship use. The adapter is highly rated by users, indicating satisfaction with its performance and usability. It lacks voltage conversion and surge protection, which are critical considerations when using high-power devices. It is best suited for travelers using dual voltage devices who need a reliable, multi-port adapter for various countries.

The TESSAN US to Japan plug adapter is designed primarily for travelers heading to Japan and several other countries using Type A plugs. It supports devices with voltage compatibility up to 250V but is not a voltage converter, so your electronics need to be dual voltage to avoid damage. This adapter stands out by offering four AC outlets plus three USB ports (two USB-C and one USB-A), allowing you to charge up to seven devices at once—a handy feature if you carry multiple gadgets.

The USB-C ports provide fast 15W charging, which is useful for phones and smaller electronics. Its compact size and lightweight design make it easy to pack and carry, and the thoughtful four-sided layout helps prevent large plugs from blocking each other. However, it lacks surge protection, so it might not be the best choice if you are worried about power spikes, especially in less stable power environments.

Also, while it’s great for charging phones and laptops, it’s not suitable for high-power appliances like hair dryers unless those support dual voltage. This adapter is a solid option for travelers who want multiple charging options in a small package and plan to use dual-voltage devices.

The Anker Nano Travel Adapter is a solid choice for travelers visiting Japan and many other countries, thanks to its four plug types (including Type A and I, which cover Japan) and compatibility with over 200 countries.

Its compact size and lightweight design make it easy to carry around, and the foldable pins add to its portability.

This adapter does not convert voltage, so you should ensure your devices support Japan’s 100-240V range to avoid damage. The safety features such as the 2-pin to 2-pin connection help prevent shocks, providing peace of mind while traveling. Weighing under 4 ounces and measuring just a few inches, it’s very travel-friendly, but the maximum current of 6A is suitable for most small electronics but not heavy appliances.

For those seeking a compact, multi-port adapter for Japan that handles charging multiple devices safely and efficiently, this Anker model is an excellent fit.
