Manufacturer description
The TESSAN 2 Prong to 3 Prong Outlet Adapter solves the grounding-pin problem you hit the moment you land in Tokyo, Mexico City, or Manila. It converts a single Type A wall socket into a 7-in-1 charging station: four AC outlets rated to 1875W total, two USB-C ports at 3A max each, and one USB-A port at 2.4A. That means your laptop brick, camera charger, phone, earbuds, and a travel companion's devices all run off one wall plate instead of competing for it. The USB-C ports push up to 15W, enough to top a phone off between sightseeing stops without hauling a separate wall charger. TESSAN built…
SpecPicks Verdict
SpecPicks scored TESSAN 2 Prong to 3 Prong Outlet Adapter with 4 Outlets 3 USB using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category.

Frequently Asked Questions
Does this work in Japan?
Yes. It adapts a 2-prong Type A plug to accept 3-prong grounded plugs, which is exactly the gap travelers hit with Japanese wall sockets. It also covers Mexico, Canada, the Philippines, China, Peru, Thailand, Colombia, Guatemala, Panama, Cuba, and Puerto Rico.
Will it convert voltage for my hair dryer?
No. This is a plug adapter, not a voltage converter. Your hair dryer, straightener, or curling iron must already support 100-250V dual voltage, or it will be damaged. Check the label on the device before you travel.
How many devices can I charge at the same time?
Seven. Four AC outlets share an 1875W maximum, two USB-C ports deliver up to 3A (15W) each, and one USB-A port delivers up to 2.4A.
Is it small enough to pack in a carry-on?
Yes. It measures 3.15 x 2.24 x 2.36 inches and weighs 3.46 ounces, so it slips into a laptop bag pocket or packing cube without adding noticeable bulk.
Can I use this on a cruise ship?
Yes. It has no surge protection, which is what most cruise lines require since surge-protected strips are typically confiscated at embarkation. The trade-off is no protection against power spikes for your electronics.
