Is it safe to charge my phone at a public USB port?
Reviewed answer
The risk is small. Real juice-jacking attacks are rare, but bringing your own charger costs nothing.
- When you can, use your own charger in a wall outlet, or a battery pack.
- If your phone asks to trust this computer or allow data access while plugged into a public port, say no or choose charging only.
- Keep your phone updated. Recent updates fixed the tricks researchers found.
- Don't use a cable you found or were handed by a stranger.

If your phone asks to trust a device when you plugged into a plain charger, unplug. That prompt should never appear from a charge-only port.
