Can I Bring a Power Bank on Qantas Flights? Australian Rules
Updated 2026-07-31 · Power Bank Guide
Traveling with a power bank on Qantas flights? The airline follows the same FAA limits as most carriers: any battery under 100 Wh (≈27 Ah at 3.7 V) can be carried in your hand luggage, while anything above 100 Wh but under 160 Wh needs airline approval, and batteries over 160 Wh are prohibited. A 20 000 mAh power bank (about 74 Wh) comfortably fits the qantas power bank regulations, making it a safe choice for domestic and international routes.
Understanding the FAA/ Qantas Battery Limits
Airlines measure lithium‑ion batteries in watt‑hours (Wh). To convert milliamp‑hours (mAh) to Wh, multiply by the nominal voltage (3.7 V) and divide by 1 000:
Wh = (mAh × 3.7) / 1,000
Thus a 20 000 mAh pack equals 20 000 × 3.7 ÷ 1 000 ≈ 74 Wh, well below the 100 Wh ceiling. The same rule applies to Qantas, so you can keep the charger in your carry‑on without needing special permission.
How Much Charge Does a 20 000 mAh Bank Actually Give?
Real‑world efficiency for lithium‑ion packs is about 60‑70 % because of voltage conversion losses. Using a 70 % efficiency estimate:
- iPhone 17 (≈3 200 mAh, 3.8 V) – roughly 4 full charges.
- Samsung Galaxy S24 (≈4 800 mAh) – about 3 full charges.
- Google Pixel 8 (≈4 500 mAh) – around 3 charges.
- Xiaomi Mi 13 (≈5 000 mAh) – close to 3 charges.
These numbers assume you’re using the supplied USB‑C cable at the maximum 22.5 W PD output, which speeds up charging compared with a standard 5 W wall charger.
Choosing the Right Capacity for Travel
When deciding between a 10 000 mAh, 20 000 mAh, or larger pack, consider three factors:
- Device ecosystem: If you only need to top up a single phone and a few accessories, 10 000 mAh may be enough. For multiple devices or a full‑day of heavy use, 20 000 mAh provides a safety margin.
- Weight and size: A 20 000 mAh bank typically weighs 300‑350 g and fits in a pocket or small bag. Anything above 30 000 mAh adds bulk and may edge close to the 100 Wh limit.
- Regulatory compliance: Staying under 100 Wh keeps you in the clear for Qantas and most other airlines, eliminating the need for special paperwork.
For most travelers, the 20 000 mAh sweet spot balances capacity, portability, and compliance.
Why the INIU 20000 mAh Portable Charger Stands Out
The INIU 20000 mAh Portable Charger (Flight‑Safe) checks all the boxes important for airline travel:
- At 74 Wh, it is well under the 100 Wh limit imposed by Qantas.
- It supports 22.5 W USB‑C Power Delivery, giving faster top‑ups for modern smartphones.
- Includes a USB‑C to USB‑C cable and an LED flashlight—useful for overnight layovers.
- Pocket‑sized and under 350 g, it won’t tip the weight balance of your carry‑on.
Because it’s designed with airline rules in mind, the INIU model is a reliable, hassle‑free choice for frequent flyers.
Practical Tips for Carrying Power Banks on Qantas Flights
Even with a compliant charger, follow these best practices:
- Keep it in your hand luggage: Batteries are prohibited in checked baggage due to fire risk.
- Turn it off or set to “travel mode”: Some banks have a built‑in safety switch that disables output during the flight.
- Carry the original packaging if possible: It helps security staff quickly verify capacity.
- Check for airline updates: Rules can shift, especially for long‑haul international routes.
Following these steps minimizes the chance of a surprise at the gate.
FAQ
Can I bring a 30 000 mAh power bank on a Qantas flight?
Only if the pack is under 100 Wh. A 30 000 mAh battery at 3.7 V equals 111 Wh, which exceeds the limit and would require airline approval—or you’d need to leave it behind.
Do I need to declare my power bank at security?
No, as long as it’s under 100 Wh and packed in your carry‑on. However, you may be asked to remove it from a bag for separate screening.
Is the INIU 20000 mAh charger safe for use on a plane?
Yes. Its 74 Wh rating complies with Qantas and FAA regulations, and the manufacturer includes a travel‑mode switch to disable charging during flight, meeting airline safety standards.
