A:Answer 1. TSA-approved: Power banks are not individually "TSA approved" as items, but this model (5,000mAh, ~18.5Wh) is well under the 100Wh limit, so it is allowed in carry-on luggage. It must not be placed in checked baggage.
2. Works with any case: Yes, it works with most phone cases because it charges via a physical cable (built-in USB-C connector) rather than requiring wireless contact. As long as the charging port on your phone is accessible through the case, it will work.
