Power banks are not allowed in checked luggage due to the risk of fire. They must be carried in cabin luggage, with a maximum capacity of 100Wh (some airlines allow up to 160Wh with prior approval).

Lighters are flammable and must not be placed in checked baggage. Most airlines allow one lighter in carry-on luggage, subject to specific conditions.
