What external battery can I take on the plane?
When taking an external battery on a plane, it is essential to follow airline regulations regarding battery capacity. Most airlines and aviation authorities allow external batteries with a capacity of up to 100 watt hours (Wh) in carry-on baggage. External batteries exceeding 100 Wh but less than 160 Wh may require airline approval.
For reference, a typical 20,000 mAh power bank is generally within the acceptable range if it meets these guidelines.
You can take a power bank on a plane as long as it meets the airline’s battery capacity guidelines.
As a general rule, external batteries with a capacity of up to 100 Wh are allowed in carry-on baggage. It is advisable to check specific airline policies before traveling, as different carriers may have slightly different rules. Make sure the power bank is in good condition and avoid bringing damaged or leaking ones.
Is a power bank allowed on a plane?
To convert 20,000 mAh to watt hours (Wh), you need to know the voltage of the external battery. The formula is: Wh = (mAh × Voltage) / 1000.
For a power bank operating at 3.7 volts, this would be: (20,000 mAh × 3.7 V) / 1000 = 74 Wh.
For a power bank operating at 5 volts, this would be: (20,000 mAh × 5 V) / 1,000 = 100 Wh.
How do I know if my power bank contains lithium?
The size of a power bank you can take on a plane is generally limited by its battery capacity.
Airlines generally allow external batteries with a capacity of up to 100 Wh to be carried in carry-on baggage. Larger power banks, up to 160Wh, may be permitted but often require airline approval. It is important to ensure that the power bank is within these limits to avoid any issues during security checks.
When choosing a power bank for travel, consider factors like capacity, portability, and charging speed. A power bank with a capacity of 10,000 mAh to 20,000 mAh is often suitable for extended travel, providing enough power to charge multiple devices.
Opt for a compact, lightweight model for convenience, and select one with fast charging capabilities and multiple ports if you need to charge multiple devices simultaneously.
Additionally, make sure the power bank complies with airline regulations to avoid any travel interruptions.
