TSA has issued a caution to iPhone users against utilizing public USB ports when a specific setting is activated. The great feature of luggage equipped with ports is that you can charge your devices directly from the bag — there’s no need to remove a plugged-in power bank and handle tangled wires all over the place. There are some attractive bag selections that provide this capability as well. Certain backpacks include USB ports, but you need to bring your own power bank, while other bags come with one pre-installed. Considering the TSA’s stance on electronics, how does this affect the security screening process? Is the agency actually permitted to accept luggage with integrated USB ports and power packs?
These are valid inquiries, and they have clear answers. Indeed, the TSA permits them, with some conditions. Yes, it’s akin to carrying a standalone battery or power bank. There’s a size limit that cannot be exceeded — lithium ion batteries must be under 100 watt-hours each, and lithium metal must be restricted to no more than 8 grams — and it should be in your carry-on. Checked luggage containing a built-in power bank is not allowed as it must remain in a carry-on. If the bag has only USB ports without any connections made, you are likely in the clear, but be prepared to show agents that nothing is linked. Moreover, the FAA stipulates that “battery terminals must be safeguarded against short circuit,” and even though USB ports are not technically battery terminals, similar regulations are expected to be enforced — with a flap, cap, or sleeve to shield the port.
