Devices containing lithium metal or lithium ion batteries should be carried in carry-on baggage. Most other consumer electronic devices containing batteries are allowed in carry-on and checked baggage.
For more information to portable electronic devices, see the FAA regulations.
Lithium batteries with 100 watt hours or less in a device
- Carry On Bags: Yes
- Checked Bags: Yes (Special Instructions)
Spare (uninstalled) lithium ion and lithium metal batteries, including power banks and cell phone battery charging cases, must be carried in carry-on baggage only. Lithium metal (non-rechargeable) batteries are limited to 2 grams of lithium per battery. Lithium ion (rechargeable) batteries are limited to a rating of 100 watt hours (Wh) per battery. These limits allow for nearly all types of lithium batteries used by the average person in their electronic devices.
This instruction covers spare lithium metal and spare rechargeable lithium ion batteries for personal electronics such as cameras, cell phones, laptop computers, tablets, watches, calculators, etc. This instruction also includes external battery chargers (portable rechargers and power banks) containing a lithium ion battery. For more information, see the FAA regulations on batteries.
For lithium batteries that are installed in a device (laptop, cell phone, camera, etc.), see FAA regulations for "portable electronic devices, containing batteries".
Lithium batteries with more than 100 watt hours
- Carry On Bags: Yes (Special Instructions)
- Checked Bags: No
Spare (uninstalled) lithium ion and lithium metal batteries, including power banks and cell phone battery charging cases, must be carried in carry-on baggage only.
With airline approval, passengers may also carry up to two spare larger lithium ion batteries (101–160 Wh) or lithium metal batteries (2-8 grams). This size covers the larger after-market extended-life laptop computer batteries and some larger batteries used in professional audio/visual equipment. There is a limit of two spare batteries per person for the larger lithium ion batteries described above (101–160 watt hours per battery. For more information, see the FAA regulations on batteries.
This instruction covers spare lithium metal and spare rechargeable lithium ion batteries for personal electronics such as cameras, cell phones, laptop computers, tablets, watches, calculators, etc. This instruction also includes external battery chargers (portable rechargers and power banks) containing a lithium ion battery.

Medical-Clinical Thermometer (Mercury)
- Carry On Bags: No
- Checked Bags: Yes (Special Instructions)
The FAA allows one small Medical-Clinical Thermometer (Mercury) per passenger for personal use in checked bag only.
The thermometer must be in a protective case.
Tip: Thermometers with a red line instead of silver are not mercury and not restricted. Digital thermometers are also not restricted, unless powered by lithium batteries. See FAA regulations for more information on quantity limits.
Nebulizers, CPAPs, BiPAPs, and APAPs
- Carry On Bags: Yes (Special Instructions)
- Checked Bags: Yes (Special Instructions)
Standard screening
Nebulizers, CPAPs, BiPAPs, and APAPs
Nebulizers, CPAPs, BiPAPs and APAPs as well as facemasks and tubing may remain in their carrying case for X-ray screening, but may be required to be removed from the carry-on.
Precheck screening
Nebulizers, CPAPs, BiPAPs and APAPs as well as facemasks and tubing may remain in their carrying case, and in the carry-on, for X-ray screening
Liquids associated with nebulizers are exempt from the 3-1-1 liquids rule, in reasonable quantities. For more information, see TSA special procedures.
Devices containing lithium metal or lithium ion batteries should be carried in carry-on baggage. Most other consumer electronic devices containing batteries are allowed in carry-on and checked baggage.

Non-Spillable Wet Batteries
- Carry On Bags: Yes (Special Instructions)
- Checked Bags: Yes (Special Instructions)
The information in this entry is limited to non-spillable batteries with absorbed electrolyte (gel cell, absorbed glass mat, etc.) used in portable electronic devices. It does not cover large vehicle batteries. For battery-powered wheelchairs and mobility devices, see separate entry.
The battery voltage must not exceed 12 volts and the battery watt hour rating must not exceed 100 watt hours.
Battery-powered equipment must be protected against accidental activation and the evolution of heat, and damage to the terminal posts. See FAA regulations for full packaging requirements.
No more than two spare (not installed in device/equipment) batteries may be carried.
Phone Chargers
Portable chargers or power banks containing a lithium ion battery must be packed in carry-on bags.
Power Banks
