I would like to charge my iPhone using a USB plug on my Windows PC at work. However, any time I begin charging with the phone unlocked, it prompts me:

Trust This Computer
Your settings and data will be accessible from this computer when connected.
Trust Don't Trust

In my case, I never want to trust this PC, and I never want to accidentally click "Trust".
Is there a way to keep the phone from prompting me?


You can buy "charge only" cables. For examples open Amazon and type "usb charge only cable" in search.

Electrically a "charge only" just connects the power pins, and not the serial date pins between the computer and device.

  • Great idea. There are also charge-only adapters available that simply drop the two data pins. A quick search on Amazon found them for only a few dollars. – wjl Sep 12 '14 at 1:33

  • I suppose 15 hours was long enough to wait for any other contenders. :) – mskfisher Sep 12 '14 at 14:28
