When flying, you can generally bring common electrical items on a plane like smartphones, laptops, tablets, cameras, and e-readers in your carry-on bag. Small electronics, such as portable chargers and headphones, are also allowed. Larger items like hair dryers and electric shavers can typically be packed in either carry-on or checked baggage. However, some devices with lithium batteries, like e-cigarettes and power banks, must be carried in your hand luggage due to safety regulations. Always check with your airline for specific rules, especially for international flights, as some countries have different restrictions on electronic devices.
