⚖️ Why This Rule Exists: Aviation Cargo Fire Safety & Thermal Runaway Regulations (49 CFR § 175.10)
Lithium-ion batteries carry a risk of thermal runaway if crushed, short-circuited, or overheated. Because aircraft cargo fire suppression systems (Halon 1301) cannot reliably extinguish an uncontained lithium battery fire in the cargo hold, aviation safety regulations (FAA Pack Safe and ICAO Annex 18) require spare batteries and portable electronics to be transported in the passenger cabin where flight attendants can promptly deploy thermal containment bags.
Rules by security authority
United States — TSA
Cabin:
YES
Yes, power banks up to 100 Wh are allowed in carry-on. Between 100–160 Wh you need airline approval (max two).
Hold:
NO
No. Power banks are spare lithium batteries and are never allowed in checked bags due to fire risk.
Flying internationally? Security follows the country you depart from — the authority above applies at your departure airport. Customs at arrival is separate.
Power Bank Capacity, Size & Spec Thresholds
Aviation security rules change depending on specific capacity, volume, or blade length. Check your exact variant:
| Variant / Spec | Threshold | Verdict | Rule & Required Action |
|---|---|---|---|
| 10,000 mAh Power Bank (37 Wh) | 37 Wh (≤ 100 Wh band) | ✓ YES | Freely allowed in carry-on cabin baggage. Strictly prohibited in checked hold baggage. Action: Pack in cabin bag. Never pack in checked luggage. |
| 20,000 mAh Power Bank (74 Wh) | 74 Wh (≤ 100 Wh band) | ✓ YES | Calculated as (20000 mAh × 3.7 V) ÷ 1000 = 74 Wh. Well within the universal 100 Wh limit. Carry-on only. Action: Keep in carry-on. Ensure Wh/mAh capacity markings are clearly printed and legible on the casing. |
| 24,000 mAh / 26,800 mAh Power Bank (88.8–99.2 Wh) | 88.8 Wh – 99.16 Wh (Max sub-100Wh threshold) | ✓ YES | Engineered right under the FAA / TSA / IATA 100 Wh threshold. Allowed in carry-on without airline permission. Action: Carry-on only. Do not check if gate-checked at jet bridge. |
| 30,000 mAh Power Bank (111 Wh) | 111 Wh (100–160 Wh band) | ⚠ LIMITED | Exceeds 100 Wh. Requires airline operator pre-approval under FAA/ICAO rules; limited to maximum 2 spare units per passenger. Action: Contact airline before travel to request permission for 100–160 Wh battery. |
| Heavy-duty / Station > 160 Wh (> 43,243 mAh) | > 160 Wh | ✕ NO | Completely prohibited on passenger aircraft under FAA, IATA, and ICAO dangerous goods regulations. Action: Ship via certified Class 9 hazardous materials cargo freight. |
How Many Power Bank Can You Bring on a Plane?
FAA/TSA rule: Sub-100 Wh allows multiple units for personal use; 100–160 Wh is strictly capped at maximum 2 spare units with airline pre-approval.
Official regulatory posture: Where aviation authorities publish no individual numeric cap, standard carry-on dimensional and weight limits govern. Screeners retain statutory discretion to inspect bulk quantities.
Can You Use Power Bank During Flight?
Addresses passenger in-flight operational rules (e.g., vaping banned, device charging rules, consuming own alcohol prohibited) directly on the hub.
Operational airborne rules are governed under civil aviation flight safety regulations and carrier passenger conduct policies. Always obey cabin crew instructions and illuminated signs.
Brand Models vs Security Rules: Anker, Baseus, RAVPower
Airport security screeners inspect items according to universal physical dimensions, chemical classifications, and hazardous materials thresholds rather than brand labels. Major consumer brands design models specifically to comply with standard cabin allowances:
Evaluated under the general Power Bank security screening criteria. Check printed rating labels before travel.

🔍 Security Checkpoint & X-Ray Screening Advice
In standard 2D X-ray lanes, remove laptops and large power banks from your bag and place them flat in a dedicated bin with nothing above or below them. In modern 3D CT scanner lanes, they may remain packed inside your carry-on bag.

⚠️ Common Traveler Mistake to Avoid
How to Avoid It: Always keep all spare batteries, power banks, and portable chargers in your personal item backpack so they stay with you in the aircraft cabin.
Airline-Specific Rules & Carrier Baggage Limits
Carry-on only (max 100 Wh freely, 100-160 Wh max 2 with approval). Prohibited in checked luggage. If gate-checked, passenger must remove power bank.
Delta prohibits all power banks in checked baggage. Limit 20 spare batteries per traveler; max 2 between 100–160 Wh with approval.
International Customs & Destination Legality Warnings
Airport security (TSA/CATSA) only inspects flight safety. Destination customs authorities enforce whether Power Bank is legally permitted to enter:
CAAC mandates clear manufacturer capacity markings and China Compulsory Certification (3C / CCC). Unmarked or recalled power banks are confiscated at airport security.
BCAS strictly bans power banks from registered check-in baggage; must be carried in cabin baggage and removed into screening trays.
Batteries must be protected against short circuiting and carried in cabin baggage only. Maximum 100 Wh standard limit applies.
Does Power Bank Need to Be Declared at the Airport?
Power banks and lithium batteries under 100 watt-hours do not require formal declaration at domestic security checkpoints. However, if your spare battery is between 100 and 160 watt-hours, you must declare it to your airline ticket counter prior to boarding for carrier safety approval, and declare any damaged or recalled units.
What Happens if Power Bank Is Confiscated or Non-Compliant?
If a power bank or spare lithium battery is discovered in checked luggage, airport baggage screeners will remove and confiscate it without passenger notification to prevent cargo compartment fires. At security checkpoints, unlabelled banks or units exceeding 160 watt-hours will be denied boarding and surrendered to security.
How to Pack Power Bank for a Flight
Step-by-Step Traveler Decision Checklist
- 1 Placement Decision: Cabin: YES | Checked Hold: NO
- 2 Packing & Protection: Find the capacity printed on the casing: mAh ÷ 1000 × voltage = Wh (a 20,000 mAh, 3.7 V bank is 74 Wh — fine). Tape over exposed terminals, and use our battery calculator below if the label only shows mAh. One trap: on domestic flights inside China (since June 2025) your power bank must carry a visible CCC (3C) certification mark — most banks bought outside China lack it and get confiscated at security. Never let a power bank ride in checked luggage, even by accident.
- 3 Checkpoint Protocol: Keep in carry-on bag; remove into screening tray if requested.
- 4 Airline & Authority Boundary: Check airline baggage policies for individual carry-on size and weight limits.
