Yes, a 20000mAh power bank is generally allowed in your carry-on luggage on most airlines. However, power banks with a capacity over 100Wh (watt-hours) may require airline approval. To calculate the Wh, multiply the mAh by the voltage (usually 5V) and divide by 1000. For a 20000mAh power bank: 20000mAh * 5V / 1000 = 100Wh. Always verify with your airline before traveling to avoid inconveniences.
