Jet2 Power Bank Rules: Travel Smart Before You Fly

When travelling with Jet2, you may need your devices for boarding passes, directions, and entertainment. Bringing a portable charger can help keep them powered throughout your journey, but airline restrictions may limit what you can carry. That’s why it is important to understand Jet2 power bankrules before you pack.

In this article, we'll guide you through everything you need to know, from the rules to the recommended flight-approved power banks. If you're wondering, “can you take power bank on a plane Jet2?”, you'll find the answer along with the latest baggage rules below.

Can You Take a Power Bank on a Jet2 Flight?

Yes, you can take a power bank on a Jet2 flight, but it must meet the airline's safety requirements. The power bank should also be packed in your hand luggage, as lithium batteries are not permitted in the hold of the plane.

Essential Jet2 Power Bank Rules

Jet2 follows the strict guidance issued by the aviation authorities, including the recommendations of the UK Civil Aviation Authority (CAA) and the International Air Transport Association (IATA). Below are the Jet2 power bank rules every traveller should know before boarding:

Quantity and capacity limits

The Jet2 power bank limit depends on the battery's watt-hour (Wh) rating rather than its milliamp-hour (mAh) capacity. Power banks with a rating below 100Wh are permitted without prior approval, while any battery exceeding 160Wh is prohibited. Also, no more than two power banks are allowed per passenger.

Storage and placement requirements

Power banks must always be packed in your hand luggage and kept with you in the cabin, where they should be placed under the seat during the flight. This requirement exists because lithium batteries pose a greater fire risk if they are not stored in hand luggage.

In-flight usage restrictions

Power banks must not be charged or used during the flight. They should also not be used to charge or power any portable electronic devices while the plane is taxiing, taking off, or landing. Always follow instructions from the cabin crew, as these restrictions are in place to support the safe operation of the plane.

Wh labelling requirement

The watt-hour (Wh) rating of your power bank should be clearly printed on the device or shown in the manufacturer's specifications. During security screening, airline staff may need to verify this information to confirm that the battery is within the permitted limit.

Why Are Power Banks Restricted on Flights?

Power banks use lithium-ion batteries, which can overheat or catch fire if they are damaged, short-circuited, or manufactured with defects. While such incidents are uncommon, they can spread quickly if they occur on a plane, where they are more difficult for the crew to detect and manage. That’s why airlines and aviation authorities apply strict safety requirements for carrying them on board.

How to Calculate the Watt-Hours of Your Power Bank

Many power banks only display their capacity in milliamp-hours (mAh), which makes it difficult to know whether they comply with airline limits. Fortunately, you can easily convert mAh to Wh using this simple formula:

Wh = (mAh × V) ÷ 1,000

The battery voltage is usually 3.7V for most power banks. Here are the calculation steps:

1. Find the battery capacity in mAh.
2. Check the battery voltage, which is usually 3.7V unless otherwise stated.
3. Multiply the mAh by the voltage.
4. Divide the result by 1,000 to calculate the watt-hour rating.

For example, you want to bring a 20,000mAh power bank.

20,000 × 3.7 ÷ 1,000 = 74Wh

This means the power bank is below the common 100Wh airline threshold and is approved for flights with Jet2.

What If Your Power Bank Has No Wh Rating?

If your power bank does not have a visible Wh (watt-hour) rating, it may be confiscated during airport security screening because staff cannot confirm that it complies with airline safety limits. This applies even if you calculate the Wh rating yourself. To avoid this, use a power bank with a clearly printed Wh rating or capacity label and make sure it falls within the permitted Wh limit.

How to Prepare Your Power Bank for a Jet2 Flight

Once you've confirmed that your power bank meets the airline's battery limits, follow these simple steps to pack and carry it safely while avoiding unexpected issues at the gate:

• Store it in a protective pouch or separate compartment to reduce the risk of accidental damage or short circuits.
• Keep charging ports away from loose metal objects such as coins, keys, or paper clips.
• Check the power bank before travelling and avoid taking it if it’s swollen, cracked, leaking, or otherwise damaged.
