Confidence
IATA baseline only
VietJet Air is temporarily tracked against the active IATA passenger lithium-battery baseline after its previously cited official VietJet power-bank page began returning HTTP 404 to citation audit. Power banks remain carry-on only under the baseline, up to 100 Wh are generally allowed, 100-160 Wh requires airline approval and is limited to two units, and over 160 Wh is banned from passenger flights.
IATA passenger guidance limits over-100 Wh and up-to-160 Wh spare batteries or power banks to two units; use airline/airport confirmation for any stricter VietJet-specific limits until a stable official source is available.
Watt-hour limit
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
Power banks must travel in carry-on baggage under IATA passenger lithium-battery guidance.
Checked baggage
Power banks are carry-on only under IATA passenger lithium-battery guidance.
“Vietnam Airlines restricted-baggage guidance states removable lithium battery devices and power banks are accepted only in carry-on baggage and not in checked baggage.”

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 Power Bank 20000 (Integrated Cable) is recorded at 74.00 Wh and 20000 mAh, so the capacity check is tied to this exact catalog model.
Thailand departures use Wh-based passenger battery bands; mAh labels are treated as supporting capacity evidence.
VietJet Air (VJ) is evaluated as the operating carrier, with its published dangerous-goods policy included in the citation set.
Xiaomi Power Bank 20000 (Integrated Cable) has no active recall link in this catalog record, so the verdict is driven by capacity, route, airline, label, and rule evidence.
Allowed in carry-on. Final decision rests with airline and security staff.

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.
