I just use a battery pack as a go between -- I never plug my phone directly into a public charger, I either use a tiny charge cube and plug into the wall (if I can find an outlet), or recharge a battery pack that I use to charge my phone.
Another advantage of the battery pack is that I'm a lot less worried about leaving a $15 battery pack unattended while I go pick up some food than my $500 phone.
- Eduard 4y agoAll this assuming there didn't exist an exploitable firmware in your USB chargers and powerbanks, which could be used to spread a USB virus or install a payload.
- UltimateEdge 4y agoI doubt the USB data lines on a portable charger are connected to anything. When did you last update the firmware for your charger?
- asddubs 4y agothey might have a resistor to indicate how much current is okay to draw, or they might be hooked up to a chip negotiating things like the voltage for the pd protocol, but usually it will be an asic that doesn't even really have firmware
- Johnny555 4y agoAre there any $15 battery packs that have exposed firmware?
- JohnFen 4y agoNot saying they don't exist, but I've never seen a power bank that had the output data lines wired up to anything.
