Question 1

Can anyone confirm 100% that this will allow an iphone to charge off a usb port without having the iphone driver installed.

Accepted Answer

Its a data block... 
100% NO USB DATA CONNECTION!
So absolutely no need for a any data modifications on the USB host...

Question 2

I’m having an issue with no sound coming from my phone when I charge it in the car from the USB port. I read somewhere that this might help. Yes?

Accepted Answer

If the problem is that you're plugging your phone into your car to charge, and your phone is detecting your car as an "audio out", then it is at least *possible* that this may solve your problem. But even some devices can detect that "something is plugged in" even if the data port is blocked. A better solution is to figure out how to change the audio device on your phone. If it's android, you can select "charge only" when plugging into USB.

Ultimately, even if this device doesn't solve your problem, it's still helpful to have as a security device.

Question 3

does this actually block data from being sucked from your iphone and/or from data/virus being inserted into iphone? does it also chagre?

Accepted Answer

That's what it's supposed to do, yes. I bought it to be able to charge an old iphone from a VW Jetta USB port that was not compatible with the phone and it works fine for that. As far as I can see, it basically passes through the 5v connections and has no data connections so there would be no way a virus could be passed through it or data could be "sucked" out. Of course it also means you can't download photos or sync your phone or anything like that - all it does is let you charge.
So, basically, it turns a computer USB port into a non-smart charger. That also means it charges slowly at 0.5A whatever the port or charger  rating, because higher charge rates are negotiated between charger and phone, which requires data.

Question 4

Does this work with iPhone 8 and 11?

Accepted Answer

Yes. This has worked with all of my phones for the past 4 years including my current iPhone 11
