When it comes to the major UK airlines, the rules aren’t so strict. However, there are limits on how many batteries and gadgets of a certain kind you’re allowed to take on board

Jet2, BA and easyJet all have strict limits on how many gadgets passengers can bring with them on a flight.

The rise of tech powered by lithium-powered batteries, such as mobile phones, electric toothbrushes and vapes, as well as transport devices including ebikes, has caused some big issues.

Fire brigades across the UK are tackling lithium-ion battery fires at a rate of one every five hours, new figures show this week.

Concerns about fires have caused some airlines to ban certain devices. In recent years, numerous airlines have barred passengers from carrying power banks on flights amid fears they could ignite. Vietnam Airlines, Vietjet Air, and most recently Emirates have all prohibited power banks on flights, whilst Cathay Pacific introduced a similar ban last April. Other airlines have introduced prohibitions on AirPods.

When it comes to the major UK airlines, the rules aren’t so strict. However, there are limits on how many batteries and gadgets of a certain kind you’re allowed to take on board.

Jet2

Each customer is allowed to carry a maximum of 15 lithium battery-powered PEDs, such as mobile phones, laptops, tablets, watches and toothbrushes, providing the capacity of each battery doesn’t exceed:

• for lithium-ion batteries: 160Wh, or

• for lithium-metal batteries: 2g lithium content.

These devices should be carried in your hand luggage and in all cases, must be packaged in a way that protects against damage.

Customers are permitted to carry no more than 20 spare/loose lithium batteries, providing they are each individually protected against short circuit, the capacity of each battery doesn’t exceed 100Wh for lithium-ion batteries and for lithium-metal batteries, 2g lithium content.

Additionally, customers are also permitted to carry no more than two spare/loose lithium batteries with a watt-hour rating exceeding 100Wh, but not exceeding 160Wh, providing they are each individually protected against short circuit.

Customers may carry no more than two power banks per person, not exceeding 160Wh, providing they are individually protected against short circuit. In all cases these must not be charged whilst onboard the aircraft, and should not be used in-flight.

British Airways

British Airways limits lithium-ion batteries to 100Wh or less for general travel, with up to four spare batteries allowed per person in cabin baggage, provided they are protected from damage. Power banks are restricted to carry-on only, with a maximum of two, and batteries between 100-160Wh require airline approval.

• Capacity Limits: Under 100Wh: Allowed in carry-on (up to 4 spares) or installed in devices (checked or carry-on). 100Wh – 160Wh: Requires special approval. Usually limited to two spares. Over 160Wh: Forbidden on board.
• Carry-on Requirements: Spare batteries and power banks must be in hand luggage only. They must be in original packaging, or have terminals insulated with tape to prevent short circuits.

EasyJet

EasyJet requires all lithium-ion batteries, spare batteries, and power banks to be carried in cabin hand luggage only, with a general limit of 100Wh per battery (roughly 27,000mAh). Batteries above 160Wh are prohibited, while those between 100-160Wh require airline approval. Items must be protected from short circuits.

• Capacity Limit: Maximum 100Wh (or 160Wh with approval).
• Power Banks: Maximum 100Wh (~27,000mAh at 3.7V).
• Quantity: Generally up to 15-20 spare batteries/devices per person.
• Carry-on only: Absolutely no spare lithium batteries/power banks in checked luggage.

Ryanair

Ryanair strictly permits lithium batteries and power banks up to 100Wh (or ~27,000mAh) in carry-on luggage only; they are strictly prohibited in checked baggage. Passengers may carry up to 20 spare batteries/power banks (under 100Wh) that must be individually protected against short circuits.

• Capacity Limit: Batteries > 100Wh are generally not permitted.
• Carry-On Only: Spare batteries and power banks must be in your carry-on bag or on your person.

Wizz Air

Wizz Air restricts spare lithium batteries and power banks to carry-on baggage only, with a maximum capacity of 100 Wh (typically ~27,000 mAh) per unit without special approval. Batteries between 100 Wh and 160 Wh require prior approval, while those over 160 Wh are prohibited. A maximum of 2 spare batteries per person is allowed.

• Location: All spare batteries, power banks, and e-cigarettes must be in cabin baggage only. They are forbidden in checked bags.
• Standard Limit: Lithium-ion batteries up to 100 Wh are permitted for personal use without prior approval.
• Large Batteries (100–160 Wh): Batteries or power banks between 100 Wh and 160 Wh require prior approval from Wizz Air.
• Excessive Batteries (>160 Wh): Prohibited in both carry-on and checked luggage.
• Quantity Limit: Maximum of 2 spare batteries per person.

Here’s TWZ’s weekly carrier tracker monitoring America’s flattop fleet, including deployed Carrier Strike Groups (CSGs) and Amphibious Ready Groups (ARGs), using publicly available open-source information. Check out last week’s map here.

More than 20 U.S. Navy warships, two carrier strike groups among them, are enforcing the blockade of Iran in the U.S. Central Command (CENTCOM) area of responsibility (AOR). To date, CENTCOM has redirected 61 commercial vessels linked to Iran and disabled at least four attempting to run the blockade.

The Navy released new images last week of both CSGs supporting the blockade. The USS George H.W. Bush was conducting flight operations in the Arabian Sea on May 6, and recently spotted with 25 F/A-18E/F Super Hornets, two E-2D Hawkeyes, and three MH-60 Seahawks of Carrier Air Wing 7 visible on the flight deck. Unlike the Abraham Lincoln CSG, also operating in the AOR, George H.W. Bush is not equipped with 5th-generation carrier-based F-35Cs.

The Gerald R. Ford CSG transited the Strait of Gibraltar westbound and is steaming toward Norfolk. The strike group has been deployed for 322 days, as of May 11, and is expected to return home in the coming weeks. The CSG departed Norfolk in June 2025 and was initially supposed to return in January, but its deployment was extended twice to support combat operations in the Caribbean and the Middle East.

Three carriers are now underway training in preparation for future deployments. The Dwight D. Eisenhower CSG, which recently completed a 15-month availability, is working up off the east coast with AIS turned on. The George Washington CSG got underway on May 10, according to ship spotters, leaving port in Yokosuka, Japan, escorted by guided-missile cruiser USS Robert Smalls. The Theodore Roosevelt CSG is “conducting advanced training to bolster strike group readiness and capability” in the Pacific Ocean.

USS Nimitz is anchored off Rio de Janeiro, Brazil, for a five-day liberty port call. Nimitz is circumnavigating South America en route to her new homeport in Norfolk. Originally slated to be decommissioned this year, her service life was recently extended into 2027.

Another Marine Air-Ground Task Force is set to arrive in CENTCOM in the near-term. While the Boxer ARG has not been confirmed in CENTCOM as of publication, an arrival announcement could come as soon as next week. The 11th Marine Expeditionary Unit (MEU) is comprised of a command element, a Ground Combat Element, Battalion Landing Team 3/5, an Aviation Combat Element with two squadrons, Marine Medium Tiltrotor Squadron (VMM) 163 (Reinforced) and Marine Fighter Attack Squadron (VMFA) 122, and a logistics combat element. The approximately 5,000 Marines and Sailors aboard Boxer ARG will join the Tripoli ARG, already on station in the Middle East, and significantly enhance the United States’ expeditionary capabilities in the region.

Note: Positions are general approximations. Non-deployed LHA/LHD amphibious warships are not shown.
