Can you fly with a powered respirator?
The battery is 12.6V and 5200 mAh, which works out at about 66 watt-hours — under the 100 Wh line airlines draw for lithium batteries. Spares travel in carry-on, never in checked baggage. Confirm with your airline, because they set the rule.
Anyone doing installs, teaching away from home, or taking tools to a job in another country hits this before they hit anything else.
The battery is Li-Ion, 12.6V, 5200 mAh. Multiply those out and you get roughly 66 watt-hours. The threshold airlines generally use for lithium batteries carried by a passenger is 100 watt-hours, so this sits comfortably underneath it.
The rule that catches people is not capacity, it is which bag. Spare lithium batteries go in the cabin, not the hold. Tape the terminals or keep the spare in its own bag so nothing shorts against a key or a chisel.
We are not the authority here and neither is any manufacturer — the airline sets the rule and it varies. Check yours before you pack, and if you are crossing a border with several spares, check whether there is a limit on how many.
The unit itself is a blower, a filter and a hood. Nothing in it is pressurised and nothing in it is a hazardous liquid.
