Travelling with lithium batteries and lithium battery-operated devices
For everyone's safety, we have rules for bringing lithium batteries on your flight. It is important you check whether your battery or device can be carried, and how to pack them safely.
Quick lithium battery guide
Below is a quick list of battery examples, if they're allowed to be carried and where to pack them. All you'll need to know is your battery or device's power rating. Find out how to locate this.
If your battery is allowed on your flight, it's important to make sure it is packed securely, meeting our requirements.
- ✘ = prohibited
- ✔ = allowed
Low Watt hour (Wh) rating or lithium content
Lithium-ion (polymer) batteries not exceeding 100 Watt hours (Wh)
Lithium metal batteries not exceeding 2g lithium
Often used in laptops, mobile phones, power banks, power tools and shavers.
If your battery is allowed on your flight, it's important to make sure it is packed securely, meeting our requirements.
| Not exceeding 100 Watt hours (Wh) or 2g lithium | Checked-in | Carry-on |
|---|---|---|
| Installed in devices | ✔ Allowed if not possible to pack in carry-on bag | ✔ |
| Spare or loose batteries and power banks | ✘ | ✔ |

Power banks include rechargeable airpods, earbuds and hearing aid cases etc, see our devices and batteries allowed on flights section.
Medium Watt hour (Wh) rating or lithium content
Lithium-ion (polymer) batteries between 100-160 Watt hours (Wh)
Lithium metal batteries between 2-8g lithium
Often used in commercial cameras, some drones, children's ride-on toys and jump starter packs.
You are approved to carry these batteries, if the following requirements are met:
- Installed in electronic equipment in either carry-on or check-in baggage
- Spare lithium ion batteries in carry-on baggage only, protected from damage and short circuit. Limit of 2 per person
- Spare lithium metal or alloy batteries for personal medical devices only. In carry-on baggage only and protected from damage and short circuit. Limit of 2 per person
If your battery is allowed on your flight, it's important to make sure it is packed securely, meeting our requirements.
| 100-160 Watt hours (Wh) or 2-8g lithium | Checked-in | Carry-on |
|---|---|---|
| Installed in equipment | ✔ Allowed if not possible to pack in carry-on bag | ✔ |
| Spare or loose rechargeable lithium-ion batteries | ✘ | ✔ |
| Spare or loose non-rechargeable lithium metal or alloy batteries | ✘ | ✔ |

High Watt hour (Wh) rating or lithium content
Lithium-ion (polymer) batteries exceeding 160 Watt hours (Wh)
Lithium metal batteries exceeding 8g lithium
Often used in e-bikes, self-balancing boards and some skateboards. These large batteries pose an unacceptably high risk. We cannot accept them on board.

What are lithium batteries?
Lithium batteries provide a lot of power from a small size. They're used for everything from small electronic devices to electric cars.
- Lithium ion and lithium polymer batteries are rechargeable. We rate their power in Watt hours (Wh).
- Lithium metal batteries can't be recharged. We rate their power by their lithium content, in grams.
Why are lithium batteries a risk on planes?
Lithium batteries can discharge their power very quickly if they short-circuit. This can happen when unprotected, spare battery and power bank terminals contact other metal items e.g. coins, keys etc.
The more powerful the battery, the bigger the risk. That's why we limit the size and number of batteries you can bring when you fly with us.
What devices contain rechargeable lithium batteries?
If you can recharge your device, it almost certainly uses a lithium-ion battery.
Chargers that only work when plugged in to a power socket do not contain a battery.
These devices will almost always contain lithium batteries:
- Phones
- Tablets
- e-Readers
- Laptops
- Cameras
- Video cameras
- Gaming consoles
- Power tools
Which devices contain non-rechargeable lithium metal batteries?
Most everyday lithium metal batteries look like silver coins or buttons. They're often used in watches, calculators, cameras and remote car lock fobs.
If a device's batteries can't be recharged, it probably has a lithium metal battery.
Which batteries and devices are prohibited on flights?
- See "high Watt hour (Wh) rating or lithium content batteries" above for details
- Loose batteries, battery packs or power banks in your checked-in bags. You can bring them in your carry-on bags
- Personal battery-powered vehicles such as ebikes and some eScooters
- "Smart bags" with non-removable lithium batteries rated higher than 2.7Wh or 0.3g of lithium
Which devices and batteries are allowed on flights?
Devices in your carry-on bags
We recommend where possible, your battery powered devices are carried in your carry-on bags.
You can bring up to 15 personal electronic devices on board. The batteries must not exceed 100Wh, 2-8g for non-medical devices or 8g lithium for medical devices. Devices can include:
- Laptops
- Tablets
- Mobile phones
- eReaders such as a Kindle
- Personal gaming consoles
- Power tools
- e-Cigarettes, Vaping equipment etc. - must be in carry-on bags only, must not be activated or charged on board
Important
Travelling to/from Hong Kong
All Alternative Smoking Products e.g. e-cigarettes, vaping devices, vaping liquid, herbal cigarettes etc., are not permitted for carriage. Penalties apply if they are carried.
- All rechargeable AirPods, AirBuds, hearing aid cases or similar devices with a charging case (see next section)
- Cameras
- Medical devices e.g. defibrillator, glucose monitor, insulin pump etc.
Please pack your devices so they are protected from damage.
If you use a battery powered wheelchair or mobility aid, see our special assistance section.
A pacemaker doesn't count towards your electronic device limit.
Batteries in your carry-on bags
You can pack up to 20 spare batteries and power banks. They must be in your carry-on bags.
- Loose batteries need to show the original manufacturer's power rating. This will be in Watt hours (Wh), Amp hours (Ah), milliamp hours (mAh), or lithium content (LC).
- Power banks and battery packs each count as one battery.
- AirPod/AirBud cases are considered a power bank as their only function is to charge the airpods, airbuds inside.
- Pack your batteries and power banks carefully. Protect them from being damaged. Keep them away from metal objects like coins, keys, jewellery and zippers. Pack each battery in its own plastic bag, or cover its terminals with tape.
- Your batteries must be for personal use.
Devices in your checked-in baggage
You can pack up to 15 battery powered devices in your bags. We prefer you to pack your battery-powered devices in your carry-on bags. If that isn't possible, you can pack them in your checked-in bags.
- Protect your device from being damaged.
- You must turn all devices off completely. They cannot be left on 'Sleep' or 'Standby' mode.
- Ensure each device cannot turn on accidentally. Secure on/off switches in the off position with tape.
- You cannot pack devices with batteries rated higher than 160Wh or 8g of lithium.
- All spare batteries need to go in your carry-on bags.
