I have a power strip from the US I’m considering on taking for my trip rather than taking individual charging bricks, but there’s a catch: the supported voltage caps at 125v @ 60Hz while plugged in an outlet having non-replacable Type B sockets (including the plug itself) while all European homes use Types C, E & F with 230v @ 50Hz. Do hotels have a step down transformer in their inventory even if I’ve asked them?
Hotels will generally not have step down transformers in my experience. I would leave the us power strip at home. Instead get a charger like this https://us.ugreen.com/products/100w-6port-desktop-charger that can charge all your devices. It is dual voltage 50/60Hz and the power cable is removable so you can change for one with an euro plug that works almost everywhere in europe. You can bring a small adapter for the places where the euro plug doesn’t work if you are going to any.
The original charging bricks use Type A plugs (but fit on a Type B socket), despite them being extra space as its each one for multiple devices (iPhone, iPad, Macbook, Cameras, Rechargeable batteries) hence why I want to bring a power strip just to save space on luggage.
