What You'll Learn
Portable chargers are allowed in hand luggage
Portable chargers or power banks that contain lithium-ion batteries are allowed in hand luggage or carry-on bags. They are, however, prohibited in checked luggage. This regulation is shared by the TSA (Transportation Security Administration) and the FAA (Federal Aviation Administration).
The restrictions on portable chargers are based on battery capacity rather than physical size. Airlines typically limit power chargers to batteries with a maximum capacity of 100-watt hours (Wh). Chargers with a capacity of 160 Wh are allowed if you get pre-approval from the airline. The 100Wh limit covers standard electronics such as smartphones, tablets, laptops, and headphones.
Many batteries measure capacity in milliamp hours (mAh) instead of watt-hours, which can be confusing when trying to determine if your portable charger is within the allowed limit. To calculate the watt-hour (Wh) of a portable charger, you need to know the nominal voltage and the capacity. This information can usually be found on the power bank's label, packaging, or product website.
When packing a portable charger, it is important to take certain precautions. If your carry-on luggage has a dedicated charger pocket, disconnect the battery from the bag's USB ports before security screening and keep the charger in its pocket. If your luggage does not have a dedicated charger pocket, pack the battery with easy access in mind, as security agents may want to inspect it. Protect the battery from damage and pack it so that the battery ports cannot short-circuit. This can be done by preventing battery ports from contacting other metals, packing batteries in their original retail packaging, covering battery ports with tape, or using plastic bags, cases, or dedicated charger pockets.

Lithium-ion batteries are prohibited in checked luggage
The reason for this prohibition is that lithium-ion batteries are capable of overheating or short-circuiting, especially if they are damaged. This can lead to a process called thermal runaway, resulting in smoke, fire, and even explosions. In the event of a fire, flight crews can respond more quickly and effectively to a fire in the cabin than in the cargo hold.
To ensure safety and reduce the risk of fire, airlines have specific rules for travelling with portable chargers. These devices must be packed securely in carry-on luggage and easily accessible for inspection by security agents. The typical capacity allowed is less than 100 watt hours (Wh), although some airlines may allow up to 160 Wh with pre-approval.
It is important to note that if you are carrying a portable charger, you should fully charge both your devices and the battery pack before leaving home. Additionally, if your carry-on luggage has a dedicated charger pocket, you should disconnect the battery from the bag's USB ports before security screening. By following these guidelines, you can safely bring your lithium-ion battery-powered devices and chargers through the airport and on board your flight.

Power banks must be under 100Wh
Power banks and portable chargers have become a necessity, especially with the integration of inflight Wi-Fi in almost every airline. However, when it comes to air travel, there are specific regulations regarding power banks, primarily due to the safety risks associated with lithium-ion batteries.
Most airlines allow passengers to carry power banks in their carry-on luggage, but not in checked baggage, due to the risk of fire caused by lithium-ion batteries. Power banks and portable chargers that use lithium-ion batteries are prohibited in checked luggage. In the case of carry-on luggage, the power bank must be securely packed, and if the luggage has a dedicated charger pocket, the battery should be disconnected from the bag's USB ports before security screening.
The capacity of the power bank is typically limited to 100 watt-hours (Wh) by airlines. This limit covers standard electronic devices such as smartphones, tablets, laptops, and headphones. Power banks with a capacity of 160 Wh or more are not allowed in carry-on or checked baggage and must be shipped as cargo. However, some airlines may allow capacities of up to 160 Wh with prior approval.
To determine if your power bank complies with airline regulations, you need to know its watt-hour (Wh) rating, which may be calculated using the formula Wh = (mAh x V) / 1000, where V is the voltage. Most power banks have a voltage of 3.7V. A 20,000 mAh power bank, for example, would have a Wh rating of 74, which is below the 100 Wh limit.
It is important to check the specific regulations of the airline you are travelling with, as well as the regulations of your destination country, to ensure that you comply with the rules regarding power banks and portable chargers.

Chargers must be packed securely
When packing chargers for air travel, it's important to follow the relevant safety guidelines. Portable chargers or power banks containing lithium-ion batteries must be packed in carry-on luggage, and are prohibited in checked baggage due to safety regulations. This is because lithium-ion batteries contain flammable materials and can cause fires in certain conditions.
To ensure your charger is packed securely, take the following steps:
- Disconnect the battery from the bag's USB ports before security screening, especially if your luggage has a dedicated charger pocket.
- If you need to use the charger in the departure lounge, remember to disconnect the battery before boarding.
- If your luggage does not have a dedicated charger pocket, pack the battery with easy access in mind, as security agents may need to inspect it.
- Protect the battery from damage and pack it to prevent short-circuiting. This can be done by preventing battery ports from contacting other metals, using the original retail packaging, covering battery ports with tape, or placing the battery in plastic bags, cases, or dedicated charger pockets.
- Ensure the charger is securely stored and follow any crew instructions for using electronic devices during takeoff, landing, and turbulence.
It's worth noting that airlines typically limit power chargers to batteries with 100-watt hours (Wh), but you can pack batteries up to 160 Wh with airline pre-approval. Most portable chargers use milliamp hours (mAh) instead of watt-hours, so it's important to calculate the watt-hour rating of your charger to ensure it complies with airline regulations.

Battery terminals must be insulated
You can carry portable chargers or power banks containing lithium-ion batteries in your carry-on luggage when travelling through airports. However, there are certain regulations that must be followed. The Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA) require that power banks must be placed in carry-on luggage or on your person. This is because lithium batteries are considered a fire hazard, and flight crews can respond to a fire in the cabin more efficiently than in the cargo hold.
The typical capacity allowed for power banks is less than 100 watt hours (Wh), although some airlines may permit batteries with a capacity of up to 160 Wh with prior approval. The permitted capacity covers standard electronics such as smartphones, tablets, laptops, and headphones. It is important to note that the watt-hour rating, rather than the milliamp hour (mAh) capacity, determines whether a power bank is allowed on a plane.
Now, let's discuss why battery terminals must be insulated. Batteries contain toxic materials such as mercury, silver, nickel, cadmium, and lithium. These materials can pose a hazard if they leak into the environment. To prevent leakage, batteries should be properly collected, recycled, and processed. Additionally, battery terminals must be insulated to prevent electrical short circuits and potential safety hazards.
When packing batteries for travel, it is recommended to disconnect the battery from any USB ports and keep it in a dedicated charger pocket or its original retail packaging. This helps to prevent accidental activation and reduces the risk of short-circuiting. Proper insulation of battery terminals is crucial to ensure the safe transport and storage of batteries.
In the context of car battery maintenance, the term "insulation" refers to the practice of sealing the joint after making an electrical connection. Some mechanics recommend using grease on battery terminals, but this has been disputed by others who argue that grease is an insulator and cannot resist metal-to-metal contact. Instead, they suggest tightening the terminals and using battery terminals protectors to ensure proper insulation and protect against corrosion.
