Can you use a portable DVD player on a plain?

Yes, you can use a portable DVD player on a plane, but there are a few considerations. Most airlines allow personal electronic devices during flights, but you may need to keep the device in airplane mode during takeoff and landing. It's also wise to check the airline's specific policies regarding the use of personal devices. Additionally, ensure you have enough battery life or bring a charger, as in-seat power may not be available.
