PortaPow USB Data Blocker (Black 5 Pack) - Protect Against Juice Jacking

As a data blocker used with my iPhone XMax, the product works as advertised. I tested each of the 5-pack devices, one at a time, connected to my PC desktop computer using an Apple USB data/charging cable. The data ceased to transfer when attempting to backup my cell’s data. My iPhone wasn’t even recognized, but my cell’s battery was still charging. I primarily made this purchase to avoid data hacks and malware at public charging stations, such as at airports. I did my test and the data blocker works. Now, I have peace of mind. The 5-pack is reasonably priced (vs buying singularly) for sharing with family and friends.

I tested them by trying to back up my iPhone to my Mac via one, and it prevented the Mac from seeing it just fine. As far as I could tell, it didn't interfere with charging. The five-pack is great for those traveling with multiple mobile devices and a spouse who has some too. :-)

A friend charged his phone from his company computer. The computer downloaded all his data from his phone, including all his pictures of him partying.. he lost his job for violating company policy.

Easy to use and great protection.

I chose these after I had seen a news report regarding juice jacking. It was the first time I had heard of it and I was concerned that my very mobile family would be impacted. The company’s description of these, the information on their website, and the pricing for the pack size I needed made the decision clear. I personally don’t need the protection, so I am only able to rate the monetary value; but if I could rate the peace of mind I have and the appreciation my family has, I would rate those ten stars each.

This works when you are traveling and need to hook up your phone to the USB charger in the rental. It doe not down load your information to the car. Keeps your information safe.

My car is 4 years old and attempts to do the Android-Auto thing on it's screen. Almost, but nope, it's a mess. I just stick my phone up on a vent-clip holder, connect to the car's BT, and I'm fine. So, I use these on my car's USB charging ports so my car has no clue what's plugged into its USB ports. Recently traveled, and absolutely zero chance that I'd plug my phone into a random airport charger, or restaurant charger, without using one of these "charging condoms". They work exactly as advertised.

A local news station showed how easy it is to hack phones/laptops at airport charging bays or anywhere in public- even from your car -the hacker even stunned the local reporter by reading his texts to his family members, and everything else he thought he was privately doing on his phone...this is the item recommended to block public charging hacking- i ordered the 5 pack one for each family member -arrived on time-safely packed- and ready for our next trip.
