Confidence
Airline official
AirAsia is tracked from its official support article for portable electronic devices: power banks are treated separately from spare lithium batteries, are capped at two per guest, must be no more than 100 Wh per unit, are prohibited above 100 Wh, are prohibited in check-in luggage, must be carried in cabin baggage or on the person, cannot be stowed in overhead compartments, must be kept under the seat or in the seat pocket, and cannot be used or charged onboard.
Power banks up to 100 Wh are allowed; power banks over 100 Wh are prohibited.
Carry-on
Power banks are permitted only in cabin baggage or carried on the person when each unit is no more than 100 Wh, the guest carries no more than two units, and there are no signs of damage or defects.
“AirAsia's portable-electronic-devices article treats power banks separately from spare lithium batteries: maximum two power banks per guest, up to 100 Wh per unit, power banks over 100 Wh prohibited, check-in luggage prohibited, cabin or on-person carriage required, no overhead-bin stowage, under-seat or seat-pocket storage required, and onboard use or charging prohibited.”

Capacity evidence for this model
Auxiliary calculation
20,000 mAh × 3.7 V ÷ 1000 = 74.00 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.
UGREEN Nexode 100W 20000 is recorded at 74.00 Wh and 20000 mAh, so the capacity check is tied to this exact catalog model.
Hong Kong SAR is evaluated as the departure jurisdiction for country-specific power-bank overlays.
AirAsia (AK) is evaluated as the operating carrier, with its published dangerous-goods policy included in the citation set.
UGREEN Nexode 100W 20000 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 — confirm the printed Wh label.

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.
