Worked as expected, lots of USB ports.
Just used on my trip to Paris, worked well and I liked having so many USB ports. The long cord was great because my hotel was rather vintage and the outlets weren't in convenient places. Glad to see it will also work for my next trip. I appreciated that it came with adapters for the US also so I could test it at home before I left.

Perfect for travel!
These "extension cord" power adapters were perfect for us during a recent trip to Europe! They come with multiple adapters so that you can use the adapter in several countries. Best of all, one of the adapters is for North America, so we can still use them at home! Each adapter has three 3-prong plug sockets (meaning you can use either 2-prong or 3-prong plugs), one of which is set slightly apart from the other two to accommodate a larger plug. Each has four USB ports, plus one USB-C port. Plus, it has a 5-foot extension cord, so you can reach that one socket that never seems to be where you actually need it to be! That made it perfect to be able to set the adapter on the bedside table and charge all of our devices at once, but still keep our phones close at hand for checking time, setting alarms, etc. With all of that in one little box, we were able to eliminate the bag-full of various adapters we've had to pack for past trips. Definitely recommend these for your travel needs!

What an amazing adapter/outlet!
Style: Type C/G/A-Most Countries-3FT
This adapter/outlet is the best I've used for my travels (Internationally). It stands out in a crowded market with its versatility and convenience. It supports plugs from many countries, including the US, UK, EU, Asia and Africa, making it an ideal companion for travelers.
Please note: that this outlet does not convert voltage (iPhones/Tablets/Gadgets with USB connections are OK).
Design and Build Quality:
The adapter is compact and well-built, featuring a sturdy design that can withstand the rigors of travel. It fits in the of your hand (adults) and takes no luggage space at all. The 3ft cable from the outlet is helpful so that the outlet sits away from the wall allowing plenty of room on a table/stand, for multi-devices to be charged without congestion.
Functionality:
One of the standout features of this adapter is its multiple USB ports. It includes 2 USB-A and 2 USB-C port, allowing you to charge multiple devices simultaneously and quickly. This is particularly useful for charging smartphones, tablets, and other gadgets without needing multiple adapters.
Comes with 2 additional outlet attachments to be used either in UK/US/Africa/Asia
Performance:
The adapter performs exceptionally well, providing a stable and reliable connection. The USB ports offer fast charging, which is a significant advantage when you’re on the go.
Pros:
Supports plugs from many countries
Multiple USB ports (2 USB-A and 2 USB-C)
Compact and durable design
Fast charging capabilities
Cons:
None so far
Conclusion: Very happy with this International outlet that can also be used for daily usage.

Perfect accessory for travelers to Europe
Style: Type C/G/A-Most Countries-3FT
I travel to Europe yearly, so it made sense to purchase a power strip with a type C plug rather than traveling with multiple adapters. Even with a 3-foot cord, it's the perfect travel-friendly extension cord. I love that there are three standard USA outlets, as well as two each USB-C and USB-A ports. Even better, it's lightweight and doesn't take up much room in my luggage. It's very reasonably priced, has great functionality, and I highly recommend it for fellow travelers.
