With a heightened level of security and safety on airlines, regulations continue to shift and stiffen. For lithium batteries specifically, the batteries that power portable oxygen concentrators (POCs), the regulations continue to change due to accidents that have occurred in recent history.

Below are some frequently asked questions and answers to help ensure you’re in the know and prepared for your next flight!

Flying with POC FAQs

1. How Many Lithium Batteries Should I Take with Me?

Airlines and the FAA require you to bring sufficient batteries that last at least 150% of the expected flight duration. For example, if your flight is supposed to be 8 hours long, your batteries should be charged enough to last 12 hours.

2. What is the Maximum Wattage Allowed?

The TSA allows for batteries that are under 100-watt-hours (Wh) to be carried on.
Lithium batteries with more than 100-watt hours may be allowed in carry-on bags with airline approval but are limited to two spare batteries per passenger.

3. Can I Check Lithium Ion Batteries in my Checked Luggage?

No, spare (uninstalled) lithium ion and lithium metal batteries must be carried in carry-on baggage only. When a carry-on bag is checked at the gate or at planeside, all spare lithium batteries must be removed from the bag and kept with the passenger in the aircraft cabin. The battery terminals must be protected from short circuit.

4. Can I Charge my Batteries While on the Aircraft?

No, you cannot charge your battery on the aircraft. So, be sure to fully charge them in airport terminal.

5. Should I Notify my Airline Prior to my Flight?

Yes, the airline must be notified in advance that you will be flying with an FAA approved POC. Most airlines ask for at least 48 hours advanced notice.

6. Does the Airline Allow Personal POCs or Will They Require me to Rent One of Theirs?

Yes, if it is an FAA approved POC. If not, you will need to rent one.

7. Will My POC Fit Underneath My Seat?

Yes, and you should place it below your seat to allow others to move around freely.
