Flying with Laptops, Tablets and Electronics: Security and Packing Rules
Quick answer
Carry laptops, tablets, cameras and anything with a lithium battery in your cabin bag, not your checked luggage. At security you may be asked to take larger electronics out of the bag, so keep them easy to reach. Spare batteries and power banks have airline limits, so check your carrier’s rules and keep devices charged in case staff ask you to switch them on.

Cabin or hold: the short answer
Electronics belong with you. Checked bags are handled roughly, can be delayed or lost, and are a theft risk. There is also a safety reason: lithium batteries can overheat, and a fire is far easier to deal with in the cabin where crew can reach it. Most airlines and aviation authorities therefore require spare lithium batteries and power banks to travel in the cabin only.
What happens at security
Rules vary by airport. At many airports, laptops and sometimes tablets must come out of the bag and go in a separate tray. Other airports with newer scanners let you leave them in. Watch the signs, follow staff instructions and have your device accessible. Since procedures change, do not assume the last airport’s routine applies at the next one.
- Pack electronics at the top of your bag or in a dedicated sleeve.
- Put cables and chargers in one pouch so they do not tangle or clutter the tray.
- Be ready to switch a device on if asked. A flat battery can mean the device is not allowed through.
Batteries and power banks
Battery limits are expressed in watt-hours. Many airlines allow spare batteries and power banks up to a typical consumer size and set a lower cap on larger ones that need approval. Airlines also differ on how many you can carry and some carriers have introduced extra restrictions on power-bank use in flight. Read your airline’s policy, and see our guide to power bank rules for more detail.
| Item | Usual handling |
|---|---|
| Laptop or tablet | Cabin bag; switch fully off or in airplane mode as instructed |
| Power bank / spare battery | Cabin only; protect terminals from short circuit |
| Camera with battery installed | Cabin preferred; follow airline limits |
| Damaged or swollen battery | Do not fly with it |
| E-cigarettes and vapes | Cabin only, not usable on board |
Protecting gear from damage
Use a padded sleeve or case, and avoid cramming a laptop between heavy items. Overhead lockers get squeezed on full flights, so do not leave fragile items right at the edge of a loaded bag. For a camera or a drone controller, use a proper padded insert. For a flight where you are checking a bag, keep every device you cannot afford to lose in the cabin and only check low-value cables and accessories.
Preventing theft and loss
- Never leave a laptop unattended at a gate, café or charging bench.
- At security, keep an eye on your tray until you collect it, since it is one of the most common places for items to be left behind.
- Enable device location tools and a screen lock before you travel.
- Back up important files, and consider a travel-only account with limited data.
- Note serial numbers and keep proof of ownership for expensive gear.
In-flight use
You can generally use laptops and tablets in flight in flight mode, with some limits during take-off and landing. Crew may ask you to stow larger devices at those times. Wired headphones need an adapter on some devices, and wireless earbuds are usually fine in airplane mode. If you plan to work, charge before departure because seat power is not guaranteed on every aircraft, and check whether the cabin offers Wi-Fi before you rely on it.
Crossing borders with devices
Customs can inspect devices at some borders. Consider whether you really need to carry sensitive data, keep devices updated, and keep receipts for high-value gear so you can show you bought it before the trip. Some countries have specific rules on drones and certain radio equipment, so check official guidance for your destination before you pack them.
Charging and adapters
Voltage and plug types differ around the world. Most phone and laptop chargers handle a wide voltage range, but you still need the right plug shape. Our travel adapter guide explains what to buy. A single multi-port USB charger reduces the number of bricks and cables you carry.
Quick pre-flight electronics routine
Before you leave home, update your devices and charge them fully. Remove loose cards and USB sticks you do not need. Place cables in a pouch, put the laptop in a sleeve at the top of your bag and keep a small battery pack in a side pocket you can reach quickly. If you carry a camera, take the lens cap off only when shooting and keep the body in a padded section. These small habits make security fast and reduce the chance of leaving something in a tray.
On arrival, check your bag before leaving the seat area: it is easy to leave a charger plugged into a seat or a tablet in the seatback pocket.
Frequently asked questions
Can I put my laptop in checked baggage?
Airlines generally advise against it, and rules on spare lithium batteries require them in the cabin. Laptops are fragile and theft-prone, so carrying yours with you is safer.
Do I have to take my laptop out at security?
It depends on the airport and its scanners. Many require larger electronics in a separate tray, while others with newer machines do not. Follow the signs and staff instructions.
How many power banks can I bring?
Limits are set by the airline and by safety rules and are usually expressed in watt-hours and a maximum count. Check your carrier’s policy before you fly.
Can I use my tablet during take-off?
Usually in airplane mode but crew may ask you to stow larger devices during take-off and landing. Follow cabin crew instructions.
The bottom line
Keep every valuable and every lithium battery in your cabin bag, have laptops easy to reach for security, check your airline’s battery limits and protect devices with padding and sensible habits. That keeps your gear safe and your security lane quick. Start a live search on ScanFlyGo, browse the popular routes, and use the live flight tracker on the day you fly.
