Frontier Airlines power bank rules, 2026.
Frontier sticks close to the FAA standard with a tighter cap on spare batteries.
Carry-on only. Max two spares.
Frontier allows no loose lithium batteries in checked bags — they must travel in carry-on. Frontier goes further than some carriers and caps passengers at two spare lithium batteries in carry-on, each under 100 Wh.
What matters.
Under 100 Wh
Standard FAA threshold.
Two spares max
Frontier is tighter than most carriers — don’t pack three.
Carry-on only
Loose lithium batteries in checked baggage are prohibited.

Is the Clutch Pro allowed on Frontier?
Yes. The Clutch Pro is approximately 18.5 Wh (5,000 mAh × 3.7V), well under the 100 Wh carry-on limit every major airline uses.
Can I put a power bank in checked luggage?
No. Lithium-ion batteries must always travel in carry-on luggage. This is an FAA, EASA, CAA, and ICAO rule — no airline allows it.
How do I convert mAh to Wh?
Wh = (mAh ÷ 1000) × voltage. For lithium-ion power banks, voltage is typically 3.7V. So 5,000 mAh ≈ 18.5 Wh, 10,000 mAh ≈ 37 Wh, 27,000 mAh ≈ 100 Wh.
What if my power bank is over 100 Wh?
Power banks between 100–160 Wh require airline approval and are limited to two per passenger. Anything over 160 Wh is banned from passenger aircraft.
