I have only used it in the US so far. I'm excited that I found it prior to my trip to Europe.
The device comes with a cute zipper case, which I may not bring with me, but is a nice touch. I also really like that the unit has the power output of any given combination of devices plugged in on the unit itself. This will prevent headaches when I need to get a certain level of power out to a device.
I get regular FAST CHARGING on my Galaxy Ultra S21 through the USB-C port on the side of the unit. The charging current automatically splits as you add more devices. The device also keeps up with my Steam Deck.
I'm also thrilled that it comes with an additional fuse, in the event the installed one pops.
I used to carry travel adapters with removable, swappable backends, and this retractable system is great. It's 45w, and I wish it was 65w, but this is the second unit I received in the event of a problem with my main travel adapter. I also could use more USB-C ports rather than USB-A, but this may not be a problem for you depending on your devices.
I'm also happy that the device was designed to carry two 10A fuses, which is nice redundancy while travelling.
P.S. does not convert voltage, so please ensure any appliance you plug into it is capable of doing so itself.
