The Civil Aviation Authority of Vietnam (CAAV) recently issued a directive to ensure safety when transporting power banks on flights. Accordingly, power banks using lithium metal batteries must not exceed 2 g of lithium content. For those using lithium-ion batteries, the rated energy must not exceed 100 Wh.

If a power bank has a capacity exceeding 100 Wh but not more than 160 Wh, passengers can only carry it with prior airline approval.

Beyond quantity and capacity limits, passengers are prohibited from using power banks during the flight. Devices must be removed from carry-on luggage and placed in an easily observable location.

The CAAV requires power banks to be individually protected to prevent short circuits. Devices can remain in their original manufacturer's packaging, have their terminals insulated with tape, or be stored in separate plastic bags or specialized protective pouches.

The new regulations implement International Civil Aviation Organization (ICAO) standards for the safe transport of dangerous goods by air.

According to the regulatory body, lithium batteries pose potential safety risks in aviation operations. If an incident occurs, devices containing lithium batteries can cause fires or impact flight safety if not properly controlled.
