Capacity evidence for this model
Auxiliary calculation
74.00 Wh · Manufacturer-stated Wh
Threshold comparison
26.00 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.
Xiaomi Mi Power Bank 3 Pro (20000) is recorded at 74.00 Wh and 20000 mAh, so the capacity check is tied to this exact catalog model.
South Korea and Korean-carrier contexts can trigger storage or in-flight charging handling rules in addition to Wh limits.
Vietnam Airlines (VN) is evaluated as the operating carrier, with its published dangerous-goods policy included in the citation set.
Xiaomi Mi Power Bank 3 Pro (20000) has no active recall link in this catalog record, so the verdict is driven by capacity, route, airline, label, and rule evidence.
Allowed only with specific conditions. See below. (Korea/Korean-carrier power-bank handling requires explicit traveler confirmation before the trip can be treated as cleared.)
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.

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.
