2. Common Capacity (mAh) to Energy (Wh) Conversion Table

Most commercial power banks display capacity in mAh (milliampere-hours). Using standard nominal lithium-ion voltage (3.7V), the conversion formula is: Wh = (mAh × 3.7) ÷ 1000.

Rated Capacity (mAh) Calculated Energy (Wh) Asiana Airlines Boarding Status Practical Advice
5,000 mAh 18.5 Wh ✓ Approved (Safe) No declaration required; carry in cabin
10,000 mAh 37.0 Wh ✓ Approved (Safe) No declaration required; carry in cabin
20,000 mAh 74.0 Wh ✓ Approved (Safe) Most popular travel power bank size
27,000 mAh 99.9 Wh ✓ Approved (Boundary) Below 100Wh threshold; no approval needed
30,000 mAh 111.0 Wh ⚠️ Review Required Up to 2 pcs (Airline approval required)
40,000 mAh 148.0 Wh ⚠️ Review Required Up to 2 pcs (Airline approval required)
50,000 mAh or more 185.0 Wh ✕ Strictly Forbidden Confiscated at airport security checkpoint

3. Important Safety & Aviation Security Directives

🛡️ Short-Circuit Protection & Safe Packing Guidelines

Prevent exposed battery terminals from contacting metal items like keys, coins, or zippers. Keep each battery in its original retail packaging, an insulated pouch, or a separate protective sleeve.

⚡ Terminal Insulation & Packing Guidelines

Accidental contact between battery terminals and conductive metals (keys, coins, luggage zippers) can trigger electrical short-circuits and sparks. Cover ports with electrical tape or pack each battery into an individual protective plastic pouch.

4. Frequently Asked Questions (FAQ)

Airport security personnel must visually verify the rated capacity (Wh or mAh). If the text has worn off or is unreadable, the battery is treated as an unknown hazardous item and will be confiscated and destroyed at security checkpoints.
No. Batteries installed inside personal electronic devices (laptops, phones, cameras) are classified as 'lithium batteries contained in equipment' and do not count toward your spare power bank quantity limit. However, the device battery must still not exceed 100Wh (most 16-inch laptops are built at 99.6Wh).
While some carriers permit personal use at cruising altitude, in-flight charging must be stopped immediately if any abnormal heat or smoke is observed. In particular, routes passing through China and certain international carriers strictly forbid in-flight charging by law.
