Public USB ports can steal your data. Here's your safe charging plan.
Carry your own AC charger and plug into a standard power socket. It's safe—electricity only, no data.
This cheap adapter goes between a public cable and your phone. It blocks data transfer and allows only power.
If you must use a suspicious USB port, turn your phone completely OFF before plugging in to prevent data theft.
