Can you take 2 power banks on a plane?

Quantity limits: None for most batteries — but batteries must be for use by the passenger. Batteries carried for further sale or distribution (vendor samples, etc.) are prohibited. There is a limit of two spare batteries per person for the larger lithium ion batteries described above (101–160 watt hours per battery).

It's established clear rules for flying with power banks. You can take 2 power banks with you. Together, they can have a capacity of up to 27,000mAh (100Wh). Make sure you put those power banks in your carry-on luggage.

As 20000mah makes for less than 100 watt-hours, it can be carried in cabin luggage.

The FAA goes into precise details about taking power banks on planes: any battery that you take on board should not exceed 100Wh. External chargers or power banks are also considered to be a battery, and should not surpass a capacity of 27000mAh, or in other words, 100Wh.

MORE DETAILS

The reason behind this is that power banks contain lithium-ion batteries, which are considered dangerous goods by the International Air Transport Association (IATA). Lithium-ion batteries have a high energy density and, if not handled correctly, they can pose a risk of fire or explosion.

Power banks should be carried in carry-on luggage, not checked baggage. Power banks should have a capacity of no more than 100 watt-hours or 20000 milliamp hours. Above these values, airlines may require carrier approval or impose restrictions.

Lithium-ion (rechargeable) batteries and portable batteries that contain lithium-ion can only be packed in carry-on baggage. They're limited to a rating of 100 watt hours (Wh) per battery. With airline approval, you can bring two larger spare batteries (up to 160 Wh).

Lithium batteries can catch fire
While not all batteries are prohibited in checked luggage, lithium batteries are considered hazardous and should not be packed in checked bags. If a lithium battery overheats and catches fire inside the cargo hold, the fire can quickly spread and become difficult to control.

The rules on a piece of paper handed over by the security stated that you can only carry on if it is clearly marked with value <20000mAH x 5V or < 100wH. For those between 20000mAH to 32000mAH (100wH - 160wH) you have to declare and check in. Actually the rating allowed is very high, most powerbanks are much lower!

Here are the TSA's guidelines for bringing power banks on planes: Power banks that are 100 watt-hours (Wh) or less are allowed in carry-on and checked bags. Power banks that are between 100 and 160 watt-hours are allowed in carry-on bags only, and you must declare them to the TSA at the checkpoint.

Are Powerbanks allowed on planes? It will depend on the capacity in Wh (watt hours) but most commercially available ones should be OK. The IATA guidelines say that under 100Wh (multiply Ah x V to get Wh) is OK to bring on board and in cargo if installed in equipment.

Spare (uninstalled) lithium metal batteries and lithium ion batteries, electronic cigarettes and vaping devices are prohibited in checked baggage. They must be carried with the passenger in carry-on baggage.
