Not only are these ADORABLE, but nowadays they can be a life-saver in a pinch. Keep a few in your bag or purse so that they are with you when you travel. They are so small in fact, I wouldn't doubt if some folks could keep one in their wallet comfortably. If you fly a lot you should absolutely invest in these. Public chargers, while convenient, are a breeding ground for malicious hacking activity. When you plug your phone into something, it could potentially be transferring your data as well! These adapters prevent that, essentially dumbing down the cable so that it can only pass power through, not any data. This allows you to get the charge you want without the risk of data theft. If you are smart enough to not plug into those public chargers and instead carry your own, these are still handy for troubleshooting, or even to loan out to the person sitting next to you if they are unaware of the dangers posed. Ultimately I will be buying more of these to keep on hand for this purpose.

Tested with cable tester and confirmed that it blocks out D+ and D- pins, only allows Gnd, vbus, and CC1/CC2 to pass through. Don't have any high speed transfer cables to test with though. All 24 pins on the male and female side of the data blockers are also present, so unless someone is willing to send a high-speed USB-C to USB-C cable my way, we will have to take the manufacturer's word for it. I also tested charging it up to 40W without any issues, although the data blocker did get slightly warm after 10mins. The metal enclosure helped in the heat dissipation. I guess the size is also made intentionally small so it can be kept together with any charging cable, but I personally would have preferred it to be bigger or have a loop I can attach a Keychain to so that I would misplace it easily.
