When relating this to power banks, which are normally rated in mAh (milli-amps-hour), it basically means that you can take two power banks with a maximum capacity of 27,000mAh each.
Power bank capacity is typically measured in milliamp-hours (mAh), indicating the total electrical charge the battery can store. However, the voltage of your device and the power bank itself play a crucial role in the actual number of charges you’ll get.
Most airlines set the standard limit at 100Wh per device. Power banks between 100Wh–160Wh may need airline approval, while anything above 160Wh is not permitted. Knowing these rules helps you pack smart and travel safely. Important also to check your carry on luggage size and weight before boarding to avoid suprises at airport.
The FAA limit for carry-on power banks is 100Wh. You can calculate Wh using the formula: Wh = (mAh × Voltage of battery) ÷ 1000. Most lithium-ion batteries in power banks operate at around 3.7V, making a 27,000mAh pack approximately 100Wh — the maximum allowed without special airline approval.
