Review on 🔒 JSAUX USB Data Blocker (4-Pack) - USB-A Defender for Quick Charge | Protection Against Juice Jacking, Hacking & Safe Charging - Black by Johnny Wheat

UPDATE: product B07985WW8C (EDEC brand) closes and blocks data *really*. It works with my Garmin, but this one doesn't, proving that it *does* something with the data or is faking the data. Not this one. I have a Garmin GPS that charges with a TRUE charge-only cable, but goes into file transfer mode when it detects that it's plugged into the computer's USB port. I can not change it. The Garmin rolls over and plays dead when plugged into a port that's receiving data (like in a car waiting for a memory card). This so-called data blocker makes EVERY USB socket look like a data port. Garmin will not work with this adapter even using a Samsung charger which WORKS with a regular USB cable. Wow. Does it emulate data signals even when there is no data? To return.
