Prevent iPhone "Trust this computer" on work PC 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.
