What is airline approved power bank? Regulation and product features.
Share
When traveling by air, keeping your devices charged is essential. However, strict regulations govern the types of power banks you can bring onboard. Understanding these rules will help ensure your portable charger power bank doesn't get confiscated at security checkpoints.
TSA and FAA Guidelines for Power Banks
The Transportation Security Administration (TSA) and Federal Aviation Administration (FAA) have established clear guidelines for lithium battery devices:
- Carry-on only: All portable power banks must be packed in carry-on luggage, never in checked baggage
- Capacity limitations: Power banks must have a rated energy capacity under 100Wh (approximately 27,027mAh) for unrestricted carry-on
- Higher capacity approval: Power banks between 100Wh and 160Wh (approximately 27,027mAh to 43,243mAh) require airline approval before boarding
- Quantity restrictions: Only two spare batteries between 100-160Wh are permitted per passenger
Calculating Watt-hours (Wh)
To determine if your power bank complies with regulations, check the Wh rating on the device. If only mAh is listed, use this conversion formula:
Watt-hours (Wh) = Battery capacity (Ah) × Nominal voltage (V)
Note: 1Ah = 1000mAh
The crucial element in this conversion is Voltage (V), which is typically printed on the power bank itself or its packaging, usually around 3.7V for most lithium-ion batteries.
Consider common power bank capacities and their Wh equivalents (assuming a typical 3.7V internal battery voltage):
- A 10,000mAh power bank at 3.7V is approximately 37 Wh.
- A 20,000mAh power bank at 3.7V is approximately 74 Wh.
- A 27,000mAh power bank at 3.7V is approximately 99.9 Wh.
For quick reference, the following table provides common power bank capacities and their approximate Watt-hour equivalents, along with their typical airline approval status:
Table 1: mAh to Wh Conversion Chart for Common Power Bank Capacities
mAh Capacity (approx.) | Typical Voltage (V) | Calculated Wh (approx.) | Airline Approval Status | Notes |
10,000 mAh | 3.7V | 37 Wh | Allowed (Carry-on) | Common smartphone charger capacity |
20,000 mAh | 3.7V | 74 Wh | Allowed (Carry-on) | Charges multiple devices; well within limit |
27,000 mAh | 3.7V | 99.9 Wh | Allowed (Carry-on) | Maximum for most cases without airline approval |
30,000 mAh | 3.7V | 111 Wh | Airline Approval Needed (Carry-on, max 2) | Exceeds 100Wh; requires prior airline permission |
40,000 mAh | 3.7V | 148 Wh | Airline Approval Needed (Carry-on, max 2) | Larger capacity; requires prior airline permission |
50,000 mAh | 3.7V | 185 Wh | Prohibited | Exceeds the 160Wh limit; not allowed on passenger aircraft |
Note: Always check the specific voltage printed on your power bank for the most accurate calculation. |
A 25000 mAh power bank typically falls safely under the 100Wh threshold, making it an excellent choice for travelers who need significant charging capacity without airline approval complications.
Key Features of Airline-Approved Power Banks
When selecting a power bank for air travel, consider these essential features:
1.Compliant Capacity
Choose power banks with capacities under 27,027mAh (100Wh) to avoid declaration requirements. For most travelers, a 20,000-25,000mAh capacity provides an ideal balance between charging capability and regulatory compliance.
2.Fast-Charging Capabilities
Modern portable power bank chargers with PD (Power Delivery) or QC (Quick Charge) technology can significantly reduce charging times. Look for models offering 18W, 30W, or even 65W output for fast charging.
3.Multiple Device Compatibility
Premium travel power banks feature multiple ports (USB-A, USB-C) allowing simultaneous charging of several devices—ideal for travelers carrying phones, a power bank charger for tablet, and laptops.
4.Compact Design
A compact power bank that minimizes weight and size while maximizing capacity is essential for travelers with limited space. Look for streamlined designs that easily fit in carry-on bags or even pockets.
5.Safety Features
Quality power banks include multiple protection systems against overcharging, short-circuits, and temperature fluctuations—critical factors when traveling.
Table 2: Power Bank Air Travel Checklist
Item/Rule | Requirement | Notes/Why It Matters |
Location | Carry-on baggage ONLY | Prohibited in checked luggage due to fire risk in cargo hold where incidents are harder to detect and extinguish |
Capacity (Wh) | 100 Wh or less | This covers most common consumer devices and does not require airline approval |
Larger Capacity (Wh) | 101-160 Wh | Limited to a maximum of two batteries per person, and requires prior airline approval |
Prohibited Capacity | Over 160 Wh | Any power bank exceeding this limit is not allowed on passenger aircraft |
Device Condition | No damage or recall | Damaged, defective, or recalled batteries pose severe fire risks and are strictly prohibited |
In-Flight Use | No recharging on board | Recharging power banks or devices using power banks is not permitted during flight to prevent overheating |
Gate-Checked Bags | Remove power bank | If your carry-on is gate-checked, remove the power bank and keep it with you in the aircraft cabin |
Final Check | Verify with your airline | Airline policies can sometimes vary or be more stringent than general regulations; always confirm with your specific carrier |
