Operating carrier policy context
Asiana Airlines OZ
Confidence
Airline official
Asiana is tracked from its official April 17, 2026 notice: power banks are prohibited in checked baggage, limited to two units, 100-160 Wh units require airline approval, over-160 Wh units are prohibited, and onboard use/charging plus overhead-bin storage are prohibited.
Power banks: plan around the 2026 passenger-facing 100 Wh limit. Generic 100-160 Wh lithium-battery approval language is not shown as a power-bank allowance unless the airline source explicitly says so.
Carry-on
Carry-on only and must remain accessible; do not store in overhead bins.
Korea/Korean-carrier handling must be confirmed: keep the power bank accessible, out of overhead bins, and do not charge it from aircraft power.
05
Do not store the power bank in the overhead bin.
06
Power bank must not be stored in the overhead bin. Keep it in your seat pocket, on your person, or under the seat.
Notes
Recall coverage for this brand/model is not complete in CertiWatt; check the manufacturer and regulator recall pages before travel.
This trip touches Korea or a Korean carrier. Confirm the power bank can stay accessible, out of overhead bins, and not be charged from aircraft power before treating the verdict as cleared.

Threshold comparison
27.00 Wh below the passenger power-bank 100 Wh limit. The printed Wh label still takes precedence over mAh estimates.
Route-specific signals
These page-specific checks make this verdict about this model, this departure country, and this airline, not a generic power-bank answer.
Promate Mavrix-20 65W Multi-Device Charging Transparent Power Bank is recorded at 73.00 Wh and 20000 mAh, so the capacity check is tied to this exact catalog model.
Singapore is evaluated as the departure jurisdiction for country-specific power-bank overlays.
Asiana Airlines (OZ) is evaluated as the operating carrier, with its published dangerous-goods policy included in the citation set.
Promate Mavrix-20 65W Multi-Device Charging Transparent Power Bank has no active recall link in this catalog record, so the verdict is driven by capacity, route, airline, label, and rule evidence.

What to prepare before security
Keep the power bank in cabin baggage only, never checked baggage.
Make sure the Wh or mAh label is readable, or keep the manufacturer specification page available.
Use the linked citations below if staff ask why the device was flagged.
How to handle this verdict at airport security
For Conditional or Banned results, prepare evidence before you reach screening and keep the conversation factual.
1
Prepare battery documents
Have a readable Wh label or clear mAh/voltage label, any required 3C certificate or 3C mark for China-related screening, and the manufacturer specification or proof page saved offline.
2
Explain it clearly at screening
Say that the item is a lithium-ion power bank for cabin baggage only, show the Wh rating and manufacturer evidence, and point to the relevant airline or regulator citation if staff ask.
3
If it is refused, escalate safely
Ask for the specific reason, request airline or security supervisor review if available, and be ready to leave the device behind, ship it separately where legal, or use a compliant replacement. Do not move a rejected power bank into checked baggage.
Compliant alternatives for this route
These catalog models stay below the ordinary approval band and are filtered against this departure country before they are shown.
Alternative model
Promate Titan-130 130W Multi-Port Power Delivery Power Bank
Asiana Airlines (OZ) is a South Korea-based carrier. Their dangerous-goods policy is published at flyasiana.com/C/US/EN/customer/notice/detail?id=CM… This carrier publishes a power-bank quantity rule; verify the operating airline instead of treating two units as a universal ICAO/IATA cap.
Verify your specific power bank
The verdict above is for the standard Promate Mavrix-20 65W Multi-Device Charging Transparent Power Bank. If your unit has a different serial number range — especially for recalled models — verify directly:

Common questions for this exact trip
Is this a guarantee at the airport?
No. This is an informational verdict based on published sources. Airline and security staff retain final authority.
Why can the same power bank get different answers by country or airline?
Power-bank rules combine global battery limits with country overlays, airline policies, storage rules, and recall notices.
When should I re-check this route?
Re-check close to departure, especially when the trip involves China, Thailand, Korea, a recalled model, or a battery near a capacity limit.
