USB Data Blocker Adapter - 2 Pack, White - Juice Jacking Blocker & Secure Charging - Slim Portable Travel Security

I'm using this with an old MP3 player that needs to stay in charge-only mode to play uninterrupted audio files. Because of this, I'm limited to powering it from a wall plug. With Databloc, it's had no issues remaining in charging mode when plugged into smart devices.

I used the data blocker on my home computers (towers and a laptop)--sort of as a suspenders to the belts of my other computer security devices. Reasonably priced, fast delivery, a true no problem transaction and product.

If you use it it will do a job, it comes with the guarantee right on the package and that's a lifetime guarantee.

Electric conductorWorks rather fineSeems not to reduce charge speed

We do a lot of travelling and we've become concerned about the prevalence of usb A outlets in many hotels and airports. We love to use them, but were concerned about whether or not they were "secure". Now, by using this adapter, we don't need to worry anymore. We just used them on trip (at a hotel) and they worked exactly as described allowing a fast charge on our electronics.

I used it once so far and can’t tell if it did anything at all but it works so let’s hope it’ll do it’s job when needed.

Great for secure usage and airports and other places. Good size.

All Pins, including the 2 center pins, that were clearly shown as removed in the ad, are still in place on both sides of the adapter!!!DON'T BUY IT!!It's NOT as advertised!!!!!RIP OFF!!
