US plugs didn’t work
Style: Type E/F-Germany France
Got all the way to Europe only to have the US plugs not work. Couldn't get any to work and the plugs did not go in. Only usb worked. Skip it. Now i have to lug it home for a refund.

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
