does anyone have an opinion on the necessity of using a data blocker if I opt to use a public usb charging port?
@chuck34108 Yes, I would advise using a data blocker. I rely on my phone for this (if what you're charging is a phone and that's a feature). Or power off the device being charged if it will charge in that state. Another thing: charge your "dumb" battery, then use that to charge your device.
@Vanitas family vacation with variety of phones (Apple, Samsung and even a Windows (i'll never surrender (lol))). between airports and the hotel, public USB will be used for sure.
@chuck34108 Sounds like you could really use a few portable batteries. I like HALO brand, decent prices on QVC (crazy huh?). Can recharge a phone 3-5 times from near 0 to over 90% on the 3 I own.
Safe & Happy travels!
