A:Answer Good question！Generally, all external batteries with a capacity lower than 100Wh can legally and safely be taken on board airplanes according to Federal transportation security rules.
The C300X power station has a capacity of 288Wh, so according to the regulations of most airlines, it cannot be taken on board.
Many airlines may have their own regulations. Therefore, we strongly recommend that you confirm with your airline or airport before traveling with portable chargers to ensure problem-free flying.
