Cell phones, cell phone battery charging cases, laptops, cameras, smart phones, electronics, data loggers, PDAs containing lithium batteries, games, tablets, watches, etc.
Most consumer personal electronic devices containing batteries are allowed in carry-on and checked baggage, including but not limited to cell phones, smart phones, data loggers, PDAs, electronic games, tablets, laptop computers, cameras, camcorders, watches, calculators, etc. This covers typical dry cell batteries and lithium metal and lithium ion batteries for consumer electronics (AA, AAA, C, D, button cell, camera batteries, laptop batteries, etc.)
Devices containing lithium metal or lithium ion batteries (laptops, smartphones, tablets, etc.) should be carried in carry-on baggage when possible. When portable electronic devices powered by lithium batteries are in checked baggage, they must be completely powered off and protected to prevent unintentional activation or damage. In electronic devices capable of generating extreme heat, heating elements must be isolated which could cause a fire if activated, by removal of the heating element, battery or other components.
Spare (uninstalled) lithium metal and lithium ion batteries are always prohibited in checked baggage and must be placed in carry-on. When a carry-on bag is checked at the gate or at planeside, any spare lithium batteries must be removed from the bag and kept with the passenger in the aircraft cabin.
See separate entry in this chart for electronic smoking devices. These are always prohibited in checked baggage.
Quantity limits: There are no quantity limits for "personal use*," except that larger lithium ion batteries and spare nonspillable wet (gel cell, absorbed electrolyte) batteries are limited to two per person. For size restrictions on lithium metal, lithium ion, and nonspillable wet (gel cell, absorbed electrolyte) batteries, see separate "Spare batteries" entries in this table or consult "Airline Passengers and Batteries" link below. * "Personal use" does not include items for resale or distribution.
Spare batteries must be protected from damage and short circuit.
See the regulation: 49 CFR 175.10(a)(18)
Damaged or recalled batteries and battery-powered devices, which are likely to create sparks or generate a dangerous evolution of heat must not be carried aboard an aircraft (e.g. carry-on or checked baggage) unless the damaged or recalled battery has been removed, or otherwise made safe. The airline may offer further public guidance on transporting individual recalled products.
For additional information on recalls, visit the Consumer Product Safety Commission, manufacturer, or vendor website.

Sometimes, you might find yourself having to travel with multiple laptops. Whether it’s because you have to carry a work and a personal computer, or just because you prefer to use two screens, traveling with more than one of these devices can feel burdensome - they’re heavy, expensive, and they need to be protected. As
remote worker and Knackpacker Shay Alexandra says: “One of the best parts of being a remote software consultant is that I can work from anywhere in the country! The downside? Different clients often provide their own laptops, and it gets really draining (and difficult!) to fit 3-4 laptops in a bag.” And besides the physical
inconvenience factor, there’s plenty of confusing online talk of regulations around traveling with multiple laptops. Will you even be allowed to bring more than one laptop onto the plane? We’re here to share everything that you need to know about traveling with two laptops - from regulations around traveling with multiple laptops, to the best way of packing multiple laptops in your carry-on bag. In most cases, yes. But it really depends on where you’re going, and who your airline is. The Transportation Security Administration does not limit the number of
laptops that you pack in your carry-on bag, even for international flights. In fact, the @askTSA Twitter account posted that “Laptops are allowed in carry-on bags with no quantity limitations.” That said, unless you have TSA PreCheck, you’ll have to entirely remove both of your laptops and other electronics when going through security, and the electronics that you remove will need to go through the scanner in a separate bin. TSA rules are confusing,
and making a mistake can add unwanted time to your screening process. So if you have any doubts as to how to put your laptops and other electronics through security, ask an agent while you’re waiting in line. Your airline may impose limitations on the number of laptops that you can carry on to the plane. American
Airlines, for example, states that you can bring up to two laptops for personal use and two spare batteries, but no more than that without special airline permission. So while you’re very likely allowed to bring two laptops on the plane, you should always check with your airline at least a week prior to your trip. That way, you’ll know if you do need to take the time to get airline permission for traveling with all your devices. Can you bring two laptops onto the plane?

Airline rules for multiple laptops
Bringing multiple laptops through customs
You may have trouble when it comes to bringing multiple laptops into other countries… not because they’re not allowed, but because the customs departments in some countries - including certain European countries and India - impose a tariff on electronics purchased abroad.
The rationale behind these tariffs is that electronics are sometimes cheaper abroad. To avoid paying a 10-40% import duty on your second laptop, you may need a purchase receipt to prove that it’s intended for personal use.
You should also know that US customs, as well as many other countries, consider your laptops to be “baggage”. This means that your laptops are subject to search without warrant. When you travel abroad, make sure that all of your documents are backed up on a hard drive or on cloud storage, and that your personal information is password-protected in cloud storage.
Other laptop regulations
If you have a 15” MacBook Pro that was sold from the retailer between September 2015 and June 2019, you will not be allowed to bring even a single one onto the plane. The FAA recalled these devices due to overheating batteries. You can check if your MacBook has been recalled here, and if it has, then Apple will replace your battery free of charge.
How to pack two laptops in your carry-on
How you pack your laptops in your carry-on depends on your bag. So firstly, you need a laptop backpack that is suited to carry your two laptops and all the rest of the stuff that you’re bringing with you onto the plane.
1. Choose the best carry-on bag for multiple laptops
When you carry two or more laptops onto the plane, it helps if your backpack has multiple compartments. Such segmentation of your backpack helps keep all of the contents in place, even as your bag gets jostled around during travel, which in turn can help protect your laptop.
Knack Packs have an everyday carry compartment, a travel compartment, and a dedicated laptop pocket. These pockets keep your things from moving around so that you know exactly where your laptops are in your bag, and you can easily access them at any time.
And because traveling with multiple laptops also means that you’ll need to bring extra chargers and adapters, make sure that your laptop backpack has pockets that can hold and organize all of the additional laptop accessories. It’s not fun to spend time untangling a wild knot of laptop cables, especially as you’re navigating an airport.

2. Pack your laptops in your carry-on
It might be tempting to avoid dealing with your second laptop by packing it in checked baggage, but we strongly advise against this. Checked baggage is rarely handled with care, and your second laptop will get tossed around and potentially damaged. When it comes to traveling with expensive pieces of equipment, you should always try to keep them with you.
3. Put your first laptop in the laptop pocket
You should pack the laptop that you intend to use the most during your flight in the dedicated laptop pocket. Because Knack’s laptop pocket has zippered side access, you’ll be able to easily pull it out and put it away, even from a tiny airplane seat.
Depending on the size of your laptop and the laptop pocket, you may be able to store two laptops in Knack’s laptop pocket. You can compare all Knack dimensions with this helpful chart.
4. Pack your other laptops in the larger compartments
If you can’t fit both of your laptops in the laptop pocket, you can easily store the second (and third and fourth) in Knack’s travel compartment. Just make sure that these laptops are securely stored in their own protective cases.
If your laptop is small enough, you may also be able to pack it in into Knack’s microfleece-lined tablet sleeve, which is located inside the everyday carry portion of your backpack. And if you have a large stack of laptops, the expandable travel compartment - which opens like a suitcase - will make it extremely easy to remove all of your devices at security.
Another benefit of storing your other laptops in the travel compartment is that they’ll enjoy additional padding from any clothes that you pack.
5. Pack your chargers separately from your laptop
Keeping your chargers separate from your laptop will prevent them from getting horrifically tangled, and will keep them out of the way when you’re trying to remove your laptop from your bag. The Series 1 Knack Pack has a cable garage, which is perfect for holding your laptop chargers and keeping them easily accessible at the bottom of the bag. Similarly, the bottom pocket on the back wall of the Series 2 Knack Pack is designed to hold chargers and battery bricks.
Rules for using your laptop on the plane
Your laptop must fit in your carry-on luggage, either under the seat in front of you or in the overhead bin. Of course, keeping your laptop as a personal item is preferable if you want to get work done on the plane. However, there’s likely not enough space for you to use both of your laptops, even if you’re sitting in first class or business class.
You’re absolutely allowed to use your laptop on the plane, in fact, most airlines these days require you to bring your own laptop or tablet in order to access their in-flight entertainment. However, you won’t be allowed to use your laptop until the plane has reached cruising altitude, at which point the flight attendant will announce that you’re allowed to use your approved electronic devices.
Most airlines offer WiFi for a fee, but you’ll have to check with your airline to find out the specific cost. And be aware that some airline WiFi is less than awesome when crossing oceans.
