Know Before You Go: Batteries, power banks and electronic devices on a plane
People who frequently travel by plane know that the luggage on board must meet specific requirements. In a car or train, you do not have to worry at all about the capacity of the power bank you have, the size of your suitcase, or the number of liquids in your hand luggage. At the airport, the situation gets a bit more complicated. Where to pack the batteries? What are devices not allowed in checked baggage? How do the rules for carrying electronics differ from one airline to another? This article will help you better prepare for your trip.
Even if you regularly fly on airplanes, every security check involves a bit of uncertainty. We hope that the guide we have prepared will help you save unnecessary stress and properly pack your luggage, which includes electronics. Here are the main issues addressed in this article:
- Regulations and rules for carrying electronics on an airplane.
- What electronic equipment carried on an airplane requires special attention?
- Electronics in carry-on luggage.
- What kind of power bank can be taken on a plane?
- Good practices for transporting batteries and rechargeable batteries on a plane.
Safe travel with electronics
It’s worth noting at the outset that regulations related to the electronics in your luggage can be really different. Always familiarize yourself with the applicable rules before traveling. They are defined by both airlines and national regulations. Differences can include the maximum capacity of lithium-ion batteries, rules for carrying power banks, or requirements for protecting electronic devices from accidental activation. By familiarizing yourself with specific guidelines, you will avoid unpleasant surprises.
Batteries on a plane: what the restrictions are due to
The main reason for the restrictive restrictions is the risk of causing a fire. Lithium-ion and lithium-polymer batteries, which are used in most electronic devices, are sensitive to mechanical damage, vibration, and high temperatures. They can evaporate or leak, increasing the risk of ignition.
In addition, electronic devices can also interfere with an aircraft’s onboard systems (navigation or communications). Some electronic devices (e.g., drones) can also pose a safety risk to the flights themselves.
Checked baggage VS. carry-on baggage
Most of the electronic devices we most often travel with should be packed in carry-on baggage. However, there are a few exceptions, which often include drones, hoverboards, or electric scooters, among others. Remember that you should always verify what you are allowed to take on board an airline. Unfortunately, there are no top-down rules that unify these practices around the world.
These are the recommendations of a few airlines we selected. As you can see for yourself, despite the differences in the capacity of power banks, batteries, and rechargeable batteries, in each case they must be in carry-on luggage.
- British Airways — power bank must be carried in hand luggage. Maximum capacity: 160 Wh or 40000 mAh.
- EasyJet — power bank must be carried in carry-on luggage. Maximum capacity: 100 Wh or 27000 mAh.
- Emirates — spare or extra batteries (including lithium and lithium-ion batteries) can only be carried in carry-on luggage. Items that mainly serve as an energy source (e.g. power banks), are considered spare batteries. There is a limit of 20 spare batteries per passenger.
- KLM — is allowed to carry a maximum of 15 electronic devices with a lithium battery of up to 100 Wh. Devices with a lithium battery up to 160 Wh require a permit application. Prohibited to pack electronic cigarettes in checked baggage.
- LOT — power bank must be carried in carry-on baggage. Maximum capacity: 100 Wh or 27,000 mAh. If the capacity of the power bank exceeds 100 Wh, the passenger must obtain approval from the airline before departure.
- Lufthansa — power bank must be carried in carry-on baggage. Maximum capacity: 100 Wh or 20000 mAh.
- Ryanair — power bank must be carried in carry-on baggage. Maximum capacity: 100 Wh or 27000 mAh.
- Wizz Air — batteries and rechargeable batteries are not allowed in checked baggage. Lithium-ion batteries must not have a capacity greater than 100 Wh. Lithium-ion batteries with a capacity greater than 100 Wh, but not exceeding 160 Wh, may be carried with approval from Wizz Air. Once such baggage is approved, one person may carry a maximum of 2 individually secured spare batteries with a capacity of 100 to 160 Wh.
Power bank on a plane: what you should know
The above summary is the best proof that the regulations related to a seemingly innocent device can be very different. Here are the general rules you should follow if you don’t have the opportunity to verify the guidelines before you fly.
- Power banks should be carried in carry-on luggage, not checked baggage.
- Power banks should have a capacity of no more than 100 watt-hours or 20000 milliamp hours. Above these values, airlines may require carrier approval or impose restrictions.
- Power banks should be packed in a way that protects them from damage and prevents accidental activation. It is advisable to store power banks in their original packaging or cases.
- Before boarding, disconnect all USB cables from the power bank and make sure it is turned off.
- Before boarding, make sure that the power bank does not accidentally start up during the flight.
Watch out for these devices!
Power banks are not the only devices that are not recommended to pack in checked baggage. What’s more, you also won’t take some of them on board in… carry-on backpack. Then it will be necessary to send the equipment via cargo shipment. Once again, we emphasize – if you have any doubts, consult the guidelines of the airline you are traveling with or the laws in your country. Here are some devices that require special attention:
- Lithium-ion batteries with a capacity of more than 100 Wh (for batteries in electronic devices such as laptops or cameras, they usually do not exceed this value).
- Lithium or lithium-polymer batteries contain more than 2 grams of lithium per battery.
- Devices with batteries, such as hoverboards, electric scooters, etc.
- E-cigarettes, and all related products such as e-liquids and refills.
- Power banks that exceed the previously mentioned capacities.
Some airlines may have stricter regulations for carrying electronic devices. If you are the lucky owner of a drone, be sure to make sure you can take it on the plane! In some countries and on some airlines, these devices can be taken on board a plane as carry-on or checked baggage, while in others they are completely prohibited.
Carrying batteries and rechargeable batteries on the plane
Finally, here are some good practices related to the transportation of electronics. These will help you avoid both confrontations with airport staff and surprises about baggage damage. Electronic devices are not allowed during takeoff and landing, as well as when flying through certain air zones. So it’s worth making sure your equipment is turned off before you travel. If you’re carrying batteries or rechargeables “in bulk,” place them in separate pouches or covers. This will minimize the risk of the electrodes coming into contact with each other. Finger batteries are best transported in their original packaging.
Dangerous and prohibited items on a plane
As you may have guessed, power banks, rechargeable batteries, batteries and selected electronic equipment are not the only items you should be cautious about when preparing to travel. Many people do not know that it is forbidden to go through the security check with… water. This often causes passengers’ bewilderment and when confronted with other prohibited items (including flammables, sharp objects, lighters, knives or drugs) actually sounds surprising. Regulations do not allow you to bring more than 100 ml of liquids in a single bottle onto the plane.

Lithium Battery Bank: How Much Capacity Do I Need?
Did you know you can use a lithium battery bank to power everything from fishing kayaks, RVs, to off-grid vacation cabins? Lithium batteries are reliable and versatile. But you can’t use the same battery capacity to power a single navigation lightbulb in your boat as you would to power all the appliances in a house. Try that, and you’ll run out of power in no time.
That’s why it’s important to figure out how much battery capacity you require. Once you do that, you can create the perfect battery bank for your needs.
What is a Battery Bank?
A battery bank consists of two or more batteries connected together. They may be connected via series wiring or in parallel. Doing this allows you to have a larger energy storage capacity, and power your devices for a longer period of time. Battery bank sizing refers to the number of batteries you’ll need, and what size they should be.
How to Determine Battery Bank Sizing
It might seem like a daunting task at first to figure out your battery bank sizing. That’s especially true when you have large energy requirements, like powering everything in an off-grid house.
But here’s some good news: every electronic device will tell you its electrical load draw. Just look at the label or packaging. You can use this information to figure out your total energy requirement. That’s the first step to determining battery bank sizing.
So go grab a pencil, paper, and calculator (or an electronic device if that’s more your style). Take a look at the electrical load draw of each device you want to power. Then use the steps below to find out how much capacity you need for your lithium battery bank.
Step 1: Calculate Your Daily Energy Load
Look at the electrical load draw on each device. It should be in amps or watts. If it’s in amps, multiply that number by the number of hours you’ll use it per day. That’s your amp-hour requirement. You can add the daily amp-hour requirement of all devices together to get your total daily energy load.
What if it’s in watts? First, you need to divide the watts by the voltage to get the amount of amps. Then multiply the amps by the number of hours you expect to use your device per day. Finally, add up the amp-hour requirements of each device to get your total energy load.
Want to go off grid and power your house with solar and a battery bank? Take a look at your utility bill. You can estimate your energy demand by looking at how much energy you used throughout the year. Don’t forget to account for the months you have higher demand.
Step 2: Create a Lithium Battery Bank to Handle Your Energy Load
Now that you know your amp-hour requirement, you need to make a lithium battery bank to handle that load.
For example, if you need a total of 40 amp hours to power a 12 volt application, you can connect two 12V 20Ah batteries together in parallel. When you connect batteries in parallel, the amperage adds together, and the voltage stays the same.
If you connect batteries in series, you can increase the voltage. For example, let’s say you have a 24 volt trolling motor. You could make a lithium battery bank of two 12V 100Ah batteries in series, plus one 12V 125Ah to take care of the engine starter and other onboard equipment.

Other Battery Bank Sizing Considerations
Batteries don’t create energy–they only store it. So it’s important to make sure you have a way to charge your lithium battery bank.
There are a few ways to do this:
Let’s say you have a 200Ah lithium battery bank, but your solar panels don’t generate enough energy to fully charge it. Your bank won’t be able to provide 200Ah, and you’ll run out of power. In that case, you will have to get more or larger solar panels, or reduce the amount of energy you use.
The good news? Unlike lead acid batteries, a lithium battery bank won’t suffer any damage when partially charged. So the occasional cloudy day is no big deal. However, if your batteries are consistently undercharged, you’re paying for battery capacity that you’re never going to use. In that case, it’s better to choose a battery bank with less capacity that you know you can fully charge.
Here’s some more good news: our lithium batteries come in a variety of voltage and amp hour specifications. So go ahead, breathe a sigh of relief. There is a lithium battery bank that suits both your energy needs and your method of charging. Better yet, we’ve got experts standing by to help you find it.

PowerBanks How It Works
Powerbanks are becoming popular these days as our gadgets or devices were all getting smarter versatile tools in our daily lives specially for various types of communications such as calls,SMS,emails and other task,and these Smart devices (smartphones tablets) needs more power for them to work and last for a day as they should be. Normally the devices that needs a back up power are the smartphones tablets these days.And most of us individually owns one.But not all people knew how powerbank works literally.And some sellers just don’t explain on how their Powerbank works.And many people just end up buying the wrong specifications of powerbank that suits the need of their devices (such as smartphones tablets).That’s the reason I made this and compiled some facts gathered from different manufacturers and blogs site ,and made it into one instructables that may help some DIY’ers who planned to build their own powerbank or just buy the right one.
Step 1: How It Works? What Type of Powerbank to Choose?
Step 2: Choosing the Right Powerbanks:
1.How do I know which powerbank suits my device? Depending on individual needs and requirements, there are several general criteria to consider when selecting a powerbank: a) Capacity For example if your phone battery is 1500mAh and is 0% now, a powerbank with 2200mAh can charge your phone 1 time. If your phone battery is 3000mAh and is 0% now, a powerbank with 2200mAh will not be able to charge your phone to full because the phone battery capacity is higher than the powerbank. If you require a powerbank that is able to charge your phone several times, you need a powerbank with higher capacity. b) Number of output 1 output to charge 1 device, 2 outputs to charge 2 devices. c) Output specification 1A-1.5A output is generally for smartphones, 1.5A-2.0A output is generally for tablets. 2. How long do I need to charge the powerbank for the first time and subsequent time?/ How many times can a powerbank charge my phone? a) Powerbank is already pre-charged and ready to use. b) Re-charging time depends on the capacity of the powerbank, remaining power in the powerbank and the power supply. Example:.Powerbank: 13000mAh (0% remaining).Power Supply/ Input: 1000mA plug.Calculation: 13000mAh/ 800mA = minimum 16.25 hours (Why 800mA? An estimate of 20% power is consumed during the charging/ discharging process) c) Similar formula applies to calculate number of times a powerbank can charge a phone. Example:.Powerbank: 10000mAh (full at 90%).Phone Battery: 1500mAh.Calculation: (10000mAh x 90% x 80%) / 1500mAh = up to 5 times (Why 90%? Assuming the power bank is well maintained in good working condition and can conserve up to 90% power) (Why 80%? An estimate of 20% power is consumed during the charging/ discharging process) Note that the calculation is based on normal condition whereby the powerbank or device (phone/ tablet) is not in use during charging process. A running device generally consumes power therefore if your device is actively in use during the charging process, the charging performance may not meet the expectation. The above calculations are examples made simple for easy reference. Accuracy may vary.

Step 4: Difference Between Li-ion and Li-Po
Lithium-ion batteries use a variety of cathodes and electrolytes. Common combinations use an anode of lithium (Li) ions dissolved in carbon or graphite and a cathode of lithium cobalt-oxide (LiCoO2) or lithium manganese-oxide (LiMn2O4) in an liquid electrolyte of lithium salt. Because they use a liquid electrolyte, lithium-ion batteries are limited in shape to either prismatic (rectangular) or cylindrical. The cylindrical form has a similar construction to other cylindrical rechargeable batteries,Prismatic batteries have the anode and cathode inserted into the rectangular enclosure. The image link at illustrates this construction method. Lithium-Ion-Polymer batteries are the next stage in development and replace the liquid electrolyte with a plastic (or polymer) electrolyte. This allows the batteries to be made in a variety of shapes and sizes. The significant advantages of lithium-ion batteries are size, weight and energy density (the amount of power the battery can provide). Lithium-ion batteries are smaller, lighter and provide more energy than either nickel-cadmium or nickel-metal-hydride batteries. Additionally, lithium-ion batteries operate in a wider temperature range and can be recharged before they are fully discharged without creating a memory problem. As with most new technology, the disadvantage is pricing. Currently, lithium-ion and lithium-ion-polymer batteries are more expensive to manufacture than standard rechargeable batteries. Part of this expense is due to the volatile nature of lithium. Lithium-ion batteries are most commonly used in applications where one or more of the advantages (size, weight or energy) outweigh the additional cost, such as mobile telephones and mobile computing devices. Lithium-ion-polymer batteries are used when the battery needs to be a particular shape. Lithium-Ion Battery Characteristics Type Secondary Chemical Reaction Varies, depending on electrolyte. Operating Temperature 4∫ F to 140∫ F (.20∫ C to 60∫ C) Recommended for Cellular telephones, mobile computing devices.

Step 5: Facts About Lithium Ion:
Is Lithium-ion the Ideal Battery?For many years, nickel-cadmium had been the only suitable battery for portable equipment from wireless communications to mobile computing. Nickel-metal-hydride and lithium-ion emerged In the early 1990s, fighting nose-to-nose to gain customer’s acceptance. Today, lithium-ion is the fastest growing and most promising battery chemistry. The lithium-ion battery Pioneer work with the lithium battery began in 1912 under G.N. Lewis but it was not until the early 1970s when the first non-rechargeable lithium batteries became commercially available. lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy density for weight. Attempts to develop rechargeable lithium batteries failed due to safety problems. Because of the inherent instability of lithium metal, especially during charging, research shifted to a non-metallic lithium battery using lithium ions. Although slightly lower in energy density than lithium metal, lithium-ion is safe, provided certain precautions are met when charging and discharging. In 1991, the Sony Corporation commercialized the first lithium-ion battery. Other manufacturers followed suit. The energy density of lithium-ion is typically twice that of the standard nickel-cadmium. There is potential for higher energy densities. The load characteristics are reasonably good and behave similarly to nickel-cadmium in terms of discharge. The high cell voltage of 3.6 volts allows battery pack designs with only one cell. Most of today’s mobile phones run on a single cell. A nickel-based pack would require three 1.2-volt cells connected in series. Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery’s life. In addition, the self-discharge is less than half compared to nickel-cadmium, making lithium-ion well suited for modern fuel gauge applications. lithium-ion cells cause little harm when disposed. Despite its overall advantages, lithium-ion has its drawbacks. It is fragile and requires a protection circuit to maintain safe operation. Built into each pack, the protection circuit limits the peak voltage of each cell during charge and prevents the cell voltage from dropping too low on discharge. In addition, the cell temperature is monitored to prevent temperature extremes. The maximum charge and discharge current on most packs are is limited to between 1C and 2C. With these precautions in place, the possibility of metallic lithium plating occurring due to overcharge is virtually eliminated. Aging is a concern with most lithium-ion batteries and many manufacturers remain silent about this issue. Some capacity deterioration is noticeable after one year, whether the battery is in use or not. The battery frequently fails after two or three years. It should be noted that other chemistries also have age-related degenerative effects. This is especially true for nickel-metal-hydride if exposed to high ambient temperatures. At the same time, lithium-ion packs are known to have served for five years in some applications. Manufacturers are constantly improving lithium-ion. New and enhanced chemical combinations are introduced every six months or so. With such Rapid progress, it is difficult to assess how well the revised battery will age. Storage in a cool place slows the aging process of lithium-ion (and other chemistries). Manufacturers recommend storage temperatures of 15∞C (59∞F). In addition, the battery should be partially charged during storage. The manufacturer recommends a 40% charge. The most economical lithium-ion battery in terms of cost-to-energy ratio is the cylindrical 18650 (size is 18mm x 65.2mm). This cell is used for mobile computing and other applications that do not demand ultra-thin geometry. If a slim pack is required, the prismatic lithium-ion cell is the best choice. These cells come at a higher cost in terms of stored energy. Advantages ï High energy density. potential for yet higher capacities. ï Does not need prolonged priming when new. One regular charge is all that’s needed. ï Relatively low self-discharge. self-discharge is less than half that of nickel-based batteries. ï Low Maintenance. no periodic discharge is needed; there is no memory. ï Specialty cells can provide very high current to applications such as power tools. Limitations ï Requires protection circuit to maintain voltage and current within safe limits. ï Subject to aging, even if not in use. storage in a cool place at 40% charge reduces the aging effect. ï Transportation restrictions. shipment of larger quantities may be subject to regulatory control. This restriction does not apply to personal carry-on batteries. ï Expensive to manufacture. about 40 percent higher in cost than nickel-cadmium. ï Not fully mature. metals and chemicals are changing on a continuing basis. The lithium polymer battery The lithium-polymer differentiates itself from conventional battery systems in the type of electrolyte used. The original design, dating back to the 1970s, uses a dry solid polymer electrolyte. This electrolyte resembles a plastic-like film that does not conduct electricity but allows ions exchange (electrically charged atoms or groups of atoms). The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte. The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry. With a cell thickness measuring as little as one millimeter (0.039 inches), equipment designers are left to their own imagination in terms of form, shape and size. Unfortunately, the dry lithium-polymer suffers from poor conductivity. The internal resistance is too high and cannot deliver the current bursts needed to power modern communication devices and spin up the hard drives of mobile computing equipment. Heating the cell to 60∞C (140∞F) and higher increases the conductivity, a requirement that is unsuitable for portable applications. To compromise, some gelled electrolyte has been added. The commercial cells use a separator/ electrolyte membrane prepared from the same traditional porous polyethylene or polypropylene separator filled with a polymer, which gels upon filling with the liquid electrolyte. Thus the commercial lithium-ion polymer cells are very similar in chemistry and materials to their liquid electrolyte counter parts. Lithium-ion-polymer has not caught on as quickly as some analysts had expected. Its superiority to other systems and low manufacturing costs has not been realized. No improvements in capacity gains are achieved. in fact, the capacity is slightly less than that of the standard lithium-ion battery. Lithium-ion-polymer finds its market niche in wafer-thin geometries, such as batteries for credit cards and other such applications. Advantages ï Very low profile. batteries resembling the profile of a credit card are feasible. ï Flexible form factor. manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically. ï Lightweight. gelled electrolytes enable simplified packaging by eliminating the metal shell. ï Improved safety. more resistant to overcharge; less chance for electrolyte leakage. Limitations ï Lower energy density and decreased cycle count compared to lithium-ion. ï Expensive to manufacture. ï No standard sizes. Most cells are produced for high volume consumer markets. ï Higher cost-to-energy ratio than lithium-ion
