Start with a separate checklist for each flight
Divide your journey into arrival in Vietnam, domestic travel and departure or onward transit. Record the operating carrier and your cabin and checked allowance for each. Ask three separate questions: is an item permitted, where must it go, and does it fit the allowance? A permitted liquid can still make a bag overweight. Buying checked baggage does not allow you to check a power bank. For codeshares, check the airline operating the flight.
Power banks: two at most, with a readable Wh rating
The aviation authority’s 24 June 2026 notice, effective 1 July, limits each passenger to two power banks in cabin baggage only. For lithium-ion models, the standard ceiling is 100 Wh; above 100 Wh and up to 160 Wh requires advance airline approval. Two units does not mean any capacity is acceptable. Check the rating on the device before leaving. If only mAh is shown or the label is unreadable, clarify it with the manufacturer and airline before airport screening.
Keep them visible aboard, without using or charging them
Protect each power bank separately against short circuits, for example in its original packaging or an individual protective pouch. The authority requires it to be removed from your bag and kept visible aboard, with no charging of other devices or recharging of the bank itself. Vietnam Airlines also says not to leave it inside baggage or an overhead locker and to alert crew immediately to abnormalities. If a cabin case is checked at the gate, tell staff and remove its power banks first. Follow crew instructions on placement.
Vietnam Airlines liquids: domestic and international differ
Vietnam Airlines’ dedicated liquid page does not generally cap liquid volume on domestic flights, within baggage piece, size and weight limits; odorous liquids and alcohol have separate rules. Its standard international cabin rule is containers of up to 100 mL, totalling up to 1 L per passenger. Check exceptions such as medicines and infant food separately. A nearly empty large shampoo bottle is still a large container. Ask your carrier about fish sauce, alcohol or unusual items rather than treating all liquids alike.
For connections, plan around the next screening
Suppose you fly from HCMC to Da Nang, stay a few days and then leave Vietnam. Large toiletries may fit the first Vietnam Airlines domestic leg but need different packing for the international flight. Establish whether bags are checked through, where you must collect them and where screening happens again. Repack permitted checked items before bag drop, while keeping power banks in cabin baggage. Do not assume a duty-free purchase will clear every later checkpoint; check the transit airport and operating carrier.
A five-minute check before leaving your accommodation
ABIN suggests preparing your travel documents and any required approval, then checking power-bank count and labels, individual protection, liquid containers and bag weight. A bag photograph can help identification, but keep boarding passes and identity documents private. Charge your phone beforehand and save tickets and destination details offline. That avoids relying on an in-flight top-up from a power bank. This is a packing workflow, not a promise of acceptance by security, the operating airline or crew.
