Good but could be better.
Seemed to work as expected. It doesn't seem to affect the charging speeds. The size isn't overweildy. And its as simple as everything USB is. I don't have any issues with the Quality either. The only issue and its a 'me' issue more than anything. I was hoping that the charging circuit was set so I could use it to charge non PD devices, (devices that usually are USB-A to USB-C but that didn't work and I had to find a workaround for this, still which was simply going from USB-C to USB-C cable to USB-C to Micro USB adapter to use another adapter from Micro USB back to USB-C as most of my cables and chargers are smart so they don't charge anything like my recargeable Blood Pressure Cuff or my rechargable duster / Vacume among other devices.

Worked fine, and worked with other adapters all at once!
Ok, just tried these for the first time (I needed the USB-C adapter in my situation).In addition to charging my iPad, I tried it into another adapter that allowed me to use an old set of earphones and the charger simultaneously. I was nervous about so many things being plugged in simultaneously (charging data theft adapter, and an adapter that takes the charging cable and an 1/8” phone jack set of earphones, but everything worked PERFECTLY.Idid have to stop and restart the video I was watching, but that is all.So, compact size, reasonably priced, and seems to work with other adapters. What more could you want?

Block data signals on a USB cable
This "data blocker" device plugs between some USB charger and your equipment (for example, your smart phone). I find them especially handy as a "security device" to protect my phone from being hacked when using a "charging station" supplied by some business. Such "hacking" is possible because most phones use the same USB port for charging that is also used for communication between the phone and other devices and computers. So if the "charging station" happens to have been modified by some criminal (and it is not always a criminal working for the company that is supplying the "charger"), the criminal now owns my device instead of me (and such a malicious "hack" can be completed in under a second's time). However, this "data blocker" can prevent this "hack" from succeeding (by blocking all USB data communications to your device). As a result, I keep this "data blocker" in my phone's case, so I always have it with me when traveling (so I can safely use chargers that some business have provided for my convenience).One minor disadvantage of this "data blocker" is that it prevents "fast charging". This is because the "fast charging" protocol requires communications between the charger and the device (to tell the charger how much additional power the device said it was safe to send them). And since this "how much extra power can I safely send you?" communication from the charger is blocked by this device, the charger will never switch from using its basic "slow charge" power levels. So when I really need "fast charging" I instead use my own charger (that I'm pretty confident hasn't been criminally modified) and just plug it into an available power outlet. But I do like keeping these "data blocker" devices around for situations where I don't fully control the charger I'm using.And I've also found these "data blockers" handy when I simply want to charge a computer (be it a phone or a laptop) without instantly triggering its data transfer protocols. For example, I have powered USB hubs connected to multiple computers around my home. And I sometimes want to use a free port on one of those hubs as a "charger" for one of our family's phones. But if I plug the phone directly into the hub, the phone and computer both think I want them to start a data transfer (not disastrous, because I can just tell both devices no data transfer, but this behavior is annoying). However, if I plug one of these "data blockers" between the USB hub and my phone I just get a basic "slow charge" and neither device thinks I want to start a data transfer.NOTE: The version of this "data blocker" devices I purchased was the 4-pack that contains 2 basic USB-A devices, and 2 devices designed for USB-C plugs/jacks. I use both of these devices. The USB-C devices are handy with my cell phone (and also slightly smaller to carry around than the USB-A devices), as I just plug them directly into my cell phone's USB-C jack and then plug the charging cable into the other end of this "data blocker". And the USB-A devices are handy when the "charger" comes with either a basic USB-A plug or USB-A jack (as I then just plug the "data blocker" directly into the "charger", and plug my cable between this "data blocker" and the device I want to charge).

They seem to work.
I bought the re data protectors and they did not work. These fit our charger cords and seem to work! At the least they allow my phone to charge. do they protect my data?? I'm going to believe they do.

Your electricodata can’t be too secure!
Great little double adapter I purchased at a great price to help protect my electronic data like when used at transport stations, rentals and/or hotels. I can’t wait to use it with my next trip!
