Spirit Airlines power bank rules, 2026.
Spirit follows the FAA standard. Carry-on only, under 100 Wh, no overhead storage drama.
Carry-on only.
Spirit prohibits spare (uninstalled) lithium batteries in checked luggage. Every power bank must be in your carry-on. Spirit doesn’t publish a hard per-passenger number cap, but follows the FAA default of around 20 spare cells maximum for personal use.
What matters.
Under 100 Wh
FAA standard. Clutch Pro is ≈18.5 Wh.
Carry-on only
Lithium-ion in checked bags is grounds for ground-handling delays. Don’t.
Personal-use limit
No published cap, but stay within the FAA’s personal-use spirit — a few chargers, not a wholesale shipment.
15 colors. Pick yours.
The matte finish hides fingerprints, scuffs, and whatever happens after a long day.
Light, slim, Spirit-friendly.
The Clutch Pro tucks into your Spirit personal item and skips every battery-related gate question.

Is the Clutch Pro allowed on Spirit?
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.
