Delta Air Lines power bank rules, 2026.
What Delta allows, where to store it, and how to make sure your charger sails through every gate.
Carry-on only, under 100 Wh.
Delta follows the FAA standard: lithium-ion power banks up to 100 Wh travel in carry-on baggage only. Delta does not allow spare lithium batteries or power banks in checked bags under any circumstances. Power banks between 100 Wh and 160 Wh require Delta’s prior approval and are limited to two per passenger.
Accessible — not in the overhead.
Delta asks passengers to keep power banks in a place that’s easy to reach: under the seat in front of you, in the seatback pocket, or on your person. They should not be stored in the overhead bin so the crew can respond quickly if a battery shows any sign of overheating.
What matters.
Under 100 Wh
Delta’s carry-on threshold. The Clutch Pro is ≈18.5 Wh — well within it.
Keep it visible
Stow your charger under the seat or in the seatback pocket. Not the overhead.
Carry-on only
Never in checked luggage. This is non-negotiable across every Delta route.
Quick math.
Wh = (mAh ÷ 1000) × voltage. For lithium-ion power banks, voltage is typically 3.7V. So a 5,000 mAh charger like the Clutch Pro is ≈18.5 Wh, 10,000 mAh is ≈37 Wh, and 27,000 mAh is ≈100 Wh.
15 colors. Pick yours.
The matte finish hides fingerprints, scuffs, and whatever happens after a long day.
Delta-approved on every route.
The Clutch Pro at ≈18.5 Wh is well below Delta's 100 Wh limit, fits under the seat, and clears every TSA checkpoint.

Is the Clutch Pro allowed on Delta?
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.
