Works as described.
Simple piece of kit that does the intended job. I’ve had a couple of these for different connectors.

Peace of mind
Very functional and a must get for those who are wary of data theft via chargers in common areas. I found it did not affect charging speed and is great for protection.

Really useful to prevent data theft
This usb stick, only passes the cables needed for charging in public places and not data cables so no one can stake your data from public usb points (cafes, trains, hotels etc.)

Works, but not with Samsung
I've tested and it works with almost all my devices. The exception is my Samsung phone, which doesn't charge or charges really slowly 95% of the times. To understand if it was this adapter's fault, I've used other adapters I had and it also failed, so it seems that Samsung devices have some issue with USB-C to USB-C or USB-A to USB-C adapters *on the side that connects to the charger*, even if they pass data. What seems to work in my case: have a USB-C to USB-C data blocker on the side that connects to the phone. I'm not sure if it's fair to remove a star for this as it may be a Samsung problem. On the other hand, Samsung is a popular brand and some people buying this will have issues.

Simple little data blocker. Throw a couple in your IT kit bag and you will never fear using public USB sockets again.

Must Have if You Charge Your Phone Away From Home
Never leave home without this whenever I might need to charge my phone. Very useful before I installed GrapheneOS, but I still use it.

Must have w podróży i w pracy
Moim zdaniem niezbędne akcesorium w podróży, ale również w pracy czy w domu. PortaPow jest przydatny wszędzie tam, gdzie chcemy skorzystać z zasilania portu USB, ale nie chcemy wymiany danych miedzy naszym urządzeniem a nieznaną ładowarką lub obcym komputerem. Zarówno przygodne ładowarki, jak i komputery mogą być niebezpieczne ze względu na możliwość próby ataku podłączonego telefonu złośliwym oprogramowaniem. Ma to znaczenie także wszędzie tam, gdzie korzystamy z komputera np. u znajomego czy w pracy, ale nie chcemy, by rozpoczynał on synchronizację z naszym telefonem, której możemy nie być w stanie w porę anulować. Chcemy po prostu jedynie skorzystać z zasilania USB w celu doładowania. Sama koncepcja tego typu zabezpieczenia nie jest nowa, bo od dawna słyszałem o zabezpieczeniach zwanych USB condom. Jednak PortaPow jest porządnie wykonany, co budzi zaufanie i zajmuje niewiele miejsca.
