Airline Power Bank Capacity, Count & Approval Checker

Check your batteries before reaching the airport

A small capacity alone does not establish whether a battery can travel.
Battery type, rated energy per unit, the actual passenger carrying it, quantity, operator approval and baggage location all matter.
This airline power bank capacity, quantity and approval checker separates those conditions to help avoid abandoning a product or making an unnecessary last-minute purchase.

It is useful for families organizing several devices, photographers carrying spare camera batteries and travelers considering a larger power bank.
The result is a preparation aid, not an airline authorization or a guarantee of passing security.
Check that the entered specifications match the actual items and resolve outstanding questions before departure.

Supported operators, departure country and dates

Foreign departures, other or unknown operators and dates outside that window are held for manual verification rather than automatically cleared.
A return flight can have different local security requirements even on the same booking.
Check each connection, departure country and operating airline separately.
An unsupported itinerary does not erase an already known blocker such as damage or excessive capacity.

Distinguish power banks from ordinary spare batteries

For each row, enter the product name, actual owner/passenger number, quantity, capacity, carry-on or checked location, damage or recall status and label identification.
Rows with the same passenger number are added together.
Medical equipment, wheelchairs, lithium-metal cells, installed batteries and portable power stations are outside this ordinary personal lithium-ion checker.

Convert mAh to Wh, but use the rated Wh label first

If the product has a rated Wh label, use that value first.
Only calculate from voltage and mAh when Wh is absent and the battery specifications are identifiable.
Use the battery nominal voltage, not USB output voltage such as 5V or a fast-charging output setting.
A calculated number cannot establish compliance when the nominal voltage has not been verified.

Output power in W, estimated charging cycles and remaining charge are not substitutes for rated energy.
A worn-off or unidentifiable label must not be replaced with a guess from a similar-looking model.
Threshold comparisons use the unrounded capacity, regardless of how many decimals appear on screen.
Rounding must not move a battery just above 100Wh into the lower group.

Three separate quantity limits per passenger

Each group is tested separately.
This does not mean two batteries of every kind combined, nor two large power banks plus two large spares.
Above 160Wh is not permitted in this ordinary passenger carry-on or checked-baggage scope.
Exceeding the five-small-spares baseline is reported as an ordinary-limit violation, not a universal statement that no exception exists.
Korean Air may consider specific special reasons such as medical needs through a separate approval process; that exception is not automatically assessed here.

Enter a family or multi-row inventory step by step

1. Confirm the operating airline, departure country and flight date on the itinerary.
   If outside the supported scope, plan a direct airline check.
   
2. Read the labels on every item actually owned and carried by each passenger.
   Do not pool the family allowance and assign it all to one person.
   
3. Use quantity for identical products with the same specifications and condition; add rows for different items.
   Check that all rows belonging to one person use the same passenger number.
   
4. Review passenger totals and excess counts as well as individual rows.
   The checker does not automatically select an item to remove when a group exceeds its limit.
   
5. Resolve all verification and approval reasons and prepare the review text for the airline.
   Approval does not replace safe packaging, storage or onboard-use restrictions.
   

Starting values are fictional examples, not verified specifications.
Do not tick safety or specification confirmations without checking the actual facts.
An unknown-capacity item may affect the passenger group totals and therefore make other rows require verification too.

Worked examples of combined limits

Interpret allowed, approval, verification and blocked results

• Within entered rules: no restriction was found under the stored rules and confirmed inputs; this is not a boarding guarantee.
  
• Approval required: request approval from the actual operator for items above 100Wh up to 160Wh.
  Approval does not increase the ordinary capacity or quantity limits used by the checker.
  
• Verification required: specifications, label identification, personal-use scope, itinerary or date are unclear or unsupported.
  Complete the missing facts or ask the airline directly.
  
• Not permitted under ordinary rules: checked baggage, damage or recall, above-160Wh capacity or excessive ordinary quantity blocks the current combination.
  Special exceptions are not automatically evaluated.
  

The most restrictive finding is shown first, but other approval and verification reasons remain visible.
An excess count is not a recommendation about which product to remove.
With unknown items present, the displayed excess may only be a minimum based on known specifications.
A small number does not establish that every issue has been resolved.

Carry-on, storage and fire-prevention checklist

• Protect terminals individually against short circuits and use protective pouches or packaging specified by the airline.
  
• Do not put power banks in overhead bins; use an accessible, observable location such as an allowed seat pocket, following the crew instructions.
  
• Do not use a power bank to charge another device onboard and do not recharge the power bank itself onboard.
  Permission to carry is not permission to use.
  
• If a cabin bag is gate-checked, remove the batteries first and follow staff instructions.
