USB C to C Data Blocker, Anti Juice Jacking, for Charge Only, Case Friendly Design, Support up to 240W PD Charging (2-Pack), Red

Bought so that I could charge my phone from my work computer without it connecting over a data connection, so that it wouldn’t 1. trigger a security warning for connecting the phone and 2. put my work laptop at risk of malware if my phone got compromised. I’ve since also used the adapter to power my client laptop through the new work monitor’s without fear of it trying to connect to my work LAN when an Ethernet cable has been plugged into the monitor. In both scenarios the adapter has worked perfectly. Has been used for a good time now and shows no sign of wear. I would recommend this product.

Great tool to have if charging from unknown chargers in an emergency to protect your phone from USB hacking. Blocks all data access.

Excellent quality

These are smart, high quality metal finished data blockers for USB C to USB C. I bought these as I often travel and use public charging sockets on planes, airports, trains, buses, and taxis. I like that these are super compact, although that does make them easy to lose so having 2 in a pack is ideal. They work inline and you continue to use your existing cables, so if you do need data throughput, you can simply remove this from the end of the same cable. My only negative is a lack of independent authentication of testing that these work, so only have my own tests to rely on.

Here are my images, showing with and without the blocker. As you can see, it is working perfectly. The D- and D+ LEDs are not lit, which means data transfer is being blocked.

Brought these for work, I travel a lot and need security when using devices for work. This offers the protection. I even had this item tested to make sure it was blocking data reading and only charging - so far all good.Great value for money.

Slow charging speed Using my USB meter - charging my mobile, using the same cable, and connecting immediately - one following the other, the charging rate dropped from 8.1 watts to 2.45 Watts. That is it increased the charging time by about 3.3 times. Say from 1 hour to 3 hours 18 minutes.

They worked really well until I lost them because they're only small

La charge rapide fonctionne, l'ordinateur ne détecte pas le téléphone branché, c'est parfait !

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.

Funktionieren leise und ohne Probleme.

The pair of data blockers is reasonably priced and work fine.
