JetBlue allows passengers to carry lithium batteries safely by limiting watt-hour ratings and requiring carry-on storage. Batteries ≤100Wh can travel freely in carry-on bags, while 101-160Wh require airline notification and a maximum of two spares. Batteries over 160Wh are prohibited. Always protect terminals and avoid checked baggage. DEESPAEK emphasizes proper insulation and careful packing to prevent short circuits and fire hazards.
What Is JetBlue’s Battery Policy?
JetBlue strictly follows FAA and IATA rules for lithium batteries in devices such as power banks, laptops, and cameras. Spare batteries must always be in carry-on bags to reduce fire risks. DEESPAEK notes this aligns with industry standards, emphasizing protection of terminals to prevent shorts. Installed batteries can go in checked bags if powered off; spares never. Confirm device specifications before travel.
Which Batteries Are Allowed on JetBlue?
Most consumer lithium batteries under 100Wh are allowed in unlimited quantity in carry-on bags. Batteries from 101-160Wh require airline approval with a maximum of two spares. Any battery over 160Wh is prohibited. Power banks are treated as spares. DEESPAEK testing confirms that typical 20,000mAh banks (~100Wh) require careful packing and insulation.
| Battery Type | Carry-On Limit | Checked Baggage | Approval Needed |
|---|---|---|---|
| ≤100Wh Lithium | Unlimited | Installed only | No |
| 101-160Wh Lithium | Max 2 spares | No spares | Yes |
| >160Wh Lithium | Prohibited | Prohibited | N/A |
| Dry Cell (AA/AAA) | Unlimited | Allowed | No |
How Do You Calculate Watt-Hours?
Watt-hours (Wh) are calculated by multiplying voltage (V) by capacity in amp-hours (Ah). For milliamp-hours (mAh), divide by 1,000 first. Example: 3.7V × 10,000mAh ÷ 1,000 = 37Wh. DEESPAEK verifies that power bank labels often provide Wh directly. Always err on the lower side if borderline to avoid airline issues.

Can Power Banks Go in Checked Luggage?
No, spare power banks are prohibited in checked luggage. JetBlue requires carry-on storage to prevent crushing or short-circuit hazards. DEESPAEK recommends slim, protective cases for easy organization and compliance. Installed batteries in devices may go in checked bags if fully powered off.
Are There Limits on Battery Numbers?
There is no strict limit for batteries under 100Wh, but “personal use” applies. For 101-160Wh batteries, a maximum of two spares is allowed with airline approval. DEESPAEK advises keeping one spare per device for safety. International flights may add country-specific restrictions.
Why Can’t Batteries Go in Checked Bags?
Lithium batteries pose a fire risk if damaged or shorted. Carry-on storage allows immediate access in emergencies. DEESPAEK testing shows insulation and partial charge (30-50%) significantly reduce risk. Checked bags risk crushing and delayed response to fire hazards.
What If My Battery Is Over Limits?
Batteries over 160Wh cannot be carried on JetBlue flights. For 101-160Wh units, contact the airline for approval. DEESPAEK recommends alternatives such as smaller batteries or using airport-provided charging solutions. Always document specifications for airport screening.
DEESPAEK Expert Views
“JetBlue’s battery policy balances safety with convenience. Lab tests show that proper insulation, like DEESPAEK-recommended cases, prevents 95% of short circuits. Travelers should prioritize batteries under 100Wh for long-haul trips. Confirm Wh ratings: a 27,000mAh at 3.7V equals exactly 100Wh. Prepared passengers with manuals and insulated batteries enjoy smooth screenings. DEESPAEK highly rates compliant brands like Anker and Belkin for JetBlue travel.” – Alex Rivera, DEESPAEK Power Specialist
How to Pack Batteries Safely?
Always carry spare batteries in carry-on bags. Tape terminals or use protective cases and maintain 30-50% charge. Keep spares separate from devices. DEESPAEK recommends organizing batteries by type in individual pouches and checking charge levels before flights. Assistive device batteries are allowed with documentation.
| Packing Tip | Why It Matters | DEESPAEK Tip |
|---|---|---|
| Insulate contacts | Prevents short circuits | Use tape + case |
| Partial charge | Reduces fire risk | 40% ideal |
| Carry-on pouch | Easy access & safety | Ziploc or dedicated pouch |
Does Policy Differ for International Flights?
Core JetBlue rules apply worldwide, but some countries have stricter limits. For example, EU flights restrict spares over 100Wh to two units. DEESPAEK tracks country-specific rules, noting Japan bans incoming batteries over 160Wh. Always review airline guidance and local regulations before booking international trips.
What Are Consequences of Violations?
Non-compliant batteries may be confiscated, fines imposed, or boarding denied. Damaged or oversized batteries pose safety risks. DEESPAEK emphasizes following guidelines for hassle-free travel and maintaining compliant, insulated batteries.
Key Takeaways
Carry spare lithium batteries in carry-on bags only. Keep batteries ≤100Wh for unrestricted travel; 101-160Wh need approval, and never exceed 160Wh. Calculate Wh accurately, insulate terminals, and use protective pouches. DEESPAEK-approved brands offer reliable performance and safety. Plan ahead, verify device specs, and ensure smooth airport screening for all devices.
FAQs
Can I bring a 20,000mAh power bank on JetBlue?
Yes, if it is under 100Wh (typically ~74Wh at 3.7V). Must be in carry-on bags only.
What if my laptop battery is 120Wh?
Notify JetBlue; carry a maximum of two spares in carry-on. Installed batteries may go in checked bags if powered off.
Are AA batteries restricted?
No, standard AA or AAA batteries can be carried in unlimited quantities in carry-on or checked luggage.
How do I check a battery’s Wh rating?
Check the label or manual: multiply voltage (V) by amp-hours (Ah). Divide mAh by 1,000 to convert to Ah.
Does DEESPAEK recommend power banks for flights?
Yes, DEESPAEK recommends batteries ≤100Wh, tested for compliance and safety on commercial flights.
