Is a 20000mAh power bank allowed in flight in Vietnam?

Vietnam Flight Regulations for Power Banks

Can you bring a 20000mAh power bank on a plane in Vietnam?

Yes, passengers are allowed to carry up to 10 large-capacity power banks (20000mAh) on flights in Vietnam. However, it's crucial to note that certain restrictions apply to lithium-ion batteries exceeding 8 grams.

Specific Restrictions for Lithium-Ion Batteries

• Batteries with a watt-hour (Wh) rating of 100 or less: No restrictions
• Batteries with a Wh rating greater than 100 but less than 160: Must be approved by the airline
• Batteries with a Wh rating of 160 or more: Prohibited from air travel

Calculating the Wh Rating

To calculate the Wh rating of your power bank, multiply the voltage (V) by the capacity (mAh) and divide by 1000. For example, a 20000mAh power bank with a voltage of 3.7V would have a Wh rating of 74Wh (20000 x 3.7 / 1000 = 74).

Additional Guidelines for Power Banks on Flights

• Power banks must be carried in carry-on luggage only.
• Spare batteries should be packed separately and not connected to any devices.
• All power banks must be securely packed to prevent damage or overheating.

Consequences of Violations

Violating these regulations can result in:

• Confiscation of your power banks
• Fines or other penalties

Conclusion

Passengers in Vietnam are permitted to bring up to 10 large-capacity power banks (20000mAh) on flights. However, lithium-ion batteries exceeding 8 grams are subject to specific restrictions. It's essential to adhere to these regulations and calculate the Wh rating of your power bank accurately to avoid any issues during travel.
