JetBlue power bank rules, 2026.
JetBlue follows the FAA standard with a generous spare-battery allowance. Here's the breakdown.
100 Wh, carry-on only.
JetBlue allows lithium-ion power banks up to 100 Wh without approval, in carry-on baggage only. The airline’s spare-battery allowance is unusually generous: you can carry one spare battery up to 300 Wh, or two spares up to 160 Wh each, with approval.
What matters.
Under 100 Wh
Standard threshold. The Clutch Pro is ≈18.5 Wh.
Generous spare allowance
JetBlue's 160–300 Wh spare limit is higher than most carriers.
Carry-on only
Spare lithium cells and power banks are prohibited in checked bags.
Quick math.
Wh = (mAh ÷ 1000) × voltage. At 3.7V, a 5,000 mAh power bank is ≈18.5 Wh, 10,000 mAh is ≈37 Wh, and 27,000 mAh approaches the 100 Wh limit.
15 colors. Pick yours.
The matte finish hides fingerprints, scuffs, and whatever happens after a long day.
Lightweight pick for JetBlue.
Slim, magnetic, and well under JetBlue's 100 Wh threshold — the Clutch Pro is the simplest charger to pack.

Is the Clutch Pro allowed on JetBlue?
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.
