Yes, you can take most electronics on a plane, but they generally must be in your carry-on (hand luggage) for easy screening, with larger devices like laptops often needing to be removed for X-ray; spare batteries, power banks, and e-cigarettes are only allowed in carry-on, not checked bags, due to lithium battery safety, and must be protected from short circuits, with limits on quantity and battery size (Wh).
You can't bring certain electronics on flights, especially those with large lithium batteries (over 160Wh), damaged batteries, or those that can't be turned off; e-cigarettes/vapes must be carry-on only, power banks are carry-on only and can't be used onboard, and specific devices like smart bags (with removable batteries) or large transmitters (GPS, ham radios) have strict rules, requiring airline permission or being outright banned, so always check your airline's dangerous goods policy before flying.
You'll generally be able to take the following electricals on a flight with you:
Portable chargers or power banks containing a lithium ion battery must be packed in carry-on bags. Spare lithium batteries, which include both power banks and phone chargers, are prohibited in checked luggage.
Electronic devices (portable) No more than 15 lithium battery powered electronic devices (including power tools), for personal use only, permitted per passenger. Note: Watt hours (Wh) are determined by multiplying the voltage (V) by the amp hours (Ah), i.e. 12V x 5Ah = 60Wh.
Charging cables (USB cords) and plug-in power adapters for phones do not contain batteries or hazardous components, so they are allowed in both cabin hand luggage and checked baggage.
You can't bring sharp objects (knives, scissors over 4in), weapons, most tools (hammers, drills), firearms, explosives, flammable liquids/aerosols, large lithium batteries, disabling sprays (pepper spray), or large quantities of liquids (over 100ml) in your carry-on; most hazardous materials and large sporting goods are also banned due to security risks, requiring them to be checked.

Types of chargers not allowed on a plane
Other than the 100Wh/27,000mAh rule, the FAA does have some limitations: Power chargers must be for personal use only. Power chargers intended for resale are prohibited. Damaged batteries and chargers are not allowed.
Battery Safety at High Altitudes
Lithium-ion batteries don't just carry fire risks; they are also sensitive to pressure and continuous charging cycles. During a flight, changes in air pressure and cabin temperature can stress batteries that are already under load from charging devices.
Here's what to expect when taking your carry-on bag through security screening next time you fly. You will be asked to remove personal electronic devices larger than a cell phone from your carry-on bag and place them into a bin with nothing placed on or under them for X-ray screening.
It's highly unlikely to cause catastrophic failure, but mobile signals can create interference with cockpit radios and navigation systems. This is particularly problematic during critical takeoff and landing phases when clear communication matters most.
According to UK guidelines, any liquid, gel, or aerosol deodorant must be in a container of 100ml or less and placed in a clear, resealable plastic bag.
The Transportation Security Administration (TSA) doesn't ask you to keep your medicines in their original prescription bottles. But each state may have its own rules. If you aren't bringing your medicine in its original bottle, bring a copy of the prescription or a letter from your doctor.
You're allowed to carry devices like mobile phones, digital cameras or MP3 players in your hand luggage. If you're carrying any larger electrical items – a laptop, for example – you'll need to take them out of your hand luggage before you get to the security search point. This is because they'll need extra screening.
You may carry up to 20 spare batteries, including: Portable chargers/power banks. External battery chargers for phones, tablets, and laptops.
Portable chargers or power banks containing a lithium ion battery must be packed in carry-on bags. Spare lithium batteries, which include both power banks and phone chargers, are prohibited in checked luggage.
Most airlines let passengers carry power banks in their carry-on luggage, provided they meet specific capacity limits and quantity restrictions. The general rule is that flying with batteries with a capacity of 100 watt-hours (Wh) or less is permitted without special approval.
Summary for power banks: Pack them in your cabin bag, not the hold. Ensure they have some charge. Most power banks are allowed, but very large ones might need permission. Following these rules will keep both you and your luggage safe and ensure your portable charger doesn't get left on the tarmac.
You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes through the checkpoint. These are limited to 3.4 ounces (100 milliliters) or less per item. This is also known as the 3-1-1 liquids rule.
Yes, for budget airlines like Jetstar, a handbag (or personal item like a laptop bag) is generally included in the 7kg carry-on allowance, meaning the total weight of both your main carry-on and your small item must not exceed 7kg. Some full-service airlines, like Air New Zealand, offer a 7kg allowance for Economy but often permit an additional small personal item (like a handbag) on top of that, depending on your fare and status, but always check your specific airline's rules.
You can carry gels as well as tablets on board as hand luggage, just be to store them in a clear plastic bag, which in the UK has a limit of 100mls. Ideally, alongside your toiletries.
The "45-minute rule" refers to a productivity technique of working intensely for 45 minutes, followed by a 10-15 minute break, leveraging the brain's natural focus cycles (ultradian rhythms) to prevent burnout and boost efficiency, though it can also refer to airline check-in deadlines or corporate onboarding targets. The work/rest pattern helps maintain concentration, while the airport rule requires check-in 45 mins pre-flight for domestic flights.
We recommend packing all liquids, gels, and aerosols that are over 3.4 oz or 100 ml in your checked baggage, even if they are in a secure, tamper-evident bag. Liquids more than 3.4 oz or 100 ml not in a secure, tamper-evident bag must be packed in checked baggage.
(WZTV) — Travelers in the new year should be ready for tighter enforcement of carry-on luggage rules, and a new option for those without a standard ID. Most airlines now limit carry-on bags to 22 inches long, 14 inches wide and 9 inches deep, wheels and handles included.
