Bought for my upcoming European Vocation
Style: Type E/F-Germany France, Style: Type E/F-Germany France
I need a European plugadapter to use in Cruise. It seems to be permitted in a Carnival cruise line. This things has a super short power cord, so that it can hang a bit below a European wall outlet. That's a good design so that you won't block the neighbouring outlet. it's lightweight so I can put it in my baggage. the USB C ports is an essentials as it seems that other USB ports are not allowed to use in Europe after a few years. Anyway, this things is recommeded

Great for keeping family passports organized while traveling
I bought this for our family’s recent trip to Europe after struggling on a previous trip to keep track of everyone’s passports. Last year I was constantly worried about losing one or forgetting where I put them, so having everything in one place made a huge difference this time. This holder fit all four passports perfectly and still had room for cards and even a spot where I could clip my keys inside. It ended up being one of those things I used constantly throughout the trip at airports, hotels, train stations, and checkpoints. As long as I had the case with me, I felt confident all four passports were where they needed to be. The material feels durable enough for travel, and the zipper worked smoothly the whole trip. The black color also looks clean and professional without standing out too much. Pros: Holds four passports comfortably Helped keep travel documents organized Durable feel and smooth zipper Extra storage for cards, cash, or keys Lightweight enough for travel Gave me peace of mind during a busy international trip Cons: Slightly bulkier than necessary for minimalist travel Could be slimmer for people who only want passport storage without extra pockets
