JSAUX USB Data Blocker & USB C Data Blocker (4-Pack), Transparent Type A & Type C Data Blocker Only for Charge, Protect Against Juice Jacking, Prevent Hacking for Safe Charging

Works exactly as it should, looks nice, great for peace of mind during travel or for niche applications like connecting a dashcam to a car where the car wants to use anything you plug in as a USB storage device. Nice price, nice combo of USBA and C, great product.

Works as described. Mostly used for applications that didn't have smart/fast charging, so the speed I got I was happy with. Worked well for a device I wanted to power on in the car without it trying to connect to the Android Auto or whatever.

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).

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.

The deal comes with 4 plugs, 2 for USB-C to USB-C and two regular USB to USB plugs. They got them to me quickly and they seem to be made well enough. The price was right so, I’m happy I tried them.

One of these broke not long after I got it. Unable to use the broken one. I recommend finding higher quality ones than these. Update*** upon hearing about the piece that broke, JSAUX reached out to me and issued a full refund. I appreciate their willingness to make this right bc the return window had already expired. I feel so much better knowing they stand behind their products and work to make things right.

Good for car dashcams. I recently lost my dashcam power cable. I got a replacement USB C to Micro USB cable, but it is data transmission capable. My dashcam thought I was connecting it to a computer every time I plugged it into my car, causing the dashcam not to work. After troubleshooting, I found that using a data blocker or a power-only cable would solve my issues. My dashcam was no longer being made, and the manufacturer did not sell a replacement power-only cable. I searched online for a USB C to Micro USB power-only cable unsuccessfully. ChatGPT suggested a data blocker, and I bought it. It solved my data transmission issues right away, and now my dashcam works without issues again. Before you ask, my car does not come with a 12V port. Mazada, in their infinite wisdom, is no longer including that port with most of their models. My only other option was either to get a hardware kit and run the dashcam cable right into my fuse box, or get an electromechanical technician to install a 12V port. Mazda really gave me a headache. All I needed was a data blocker.

This blocker does block USB data. However, to get my expected Fast Charging speed, I must use this blocker on the POWER SUPPLY end of my USB cable, not on the "phone" end. If the blocker is used on the incorrect end, the charging speed is slow. This requirement should be mentioned in the Amazon product description. Also, when I use this blocker (on the correct cable end), the status message on my Galaxy S10e phone changes from "Fast Charging" to just "Charging", yet the phone still takes the usual (Fast Charging) time to charge. /Strange./ I don't like this uncertainty about whether my phone is properly charging, and at what speed. I would rather see the correct message. Other than that, this blocker seems well-constructed and durable. The connection pins are good, and the body is solid.

The JSAUX USB Data Blocker & USB-C Data Blocker (4-Pack) is a fantastic accessory for anyone concerned about data security while charging or connecting devices. This set includes both USB-A to USB-A and USB-C to USB adapters, providing great versatility for different devices. The transparent design is sleek and makes it easy to see the build quality, which feels durable and reliable. These blockers effectively prevent unauthorized data transfer, ensuring that only power is passed through when connected to public charging stations or shared USB ports. Compact and easy to use, this 4-pack is a smart investment for safeguarding your data while on the go. Highly recommended!

We took these along on a recent trip to the US. We wanted a little more data security while on planes and at the many airports we went through. They worked great and offered peace of mind. I'd definitely recommend them and would buy them again.

Fungerar som de ska.

Perfeito para viagens. Super aprovado

Ik heb dit gekocht om juice jacking tegen te gaan , wel je gsm opladen zonder dat ze je gegevens stelen. Het past tussen mijn lader en draad . Was zeer vlug en correct geleverd
