Does Flash use graphene batteries?

Flash, Chargeasap’s most powerful graphene power bank, integrates Panasonic graphene composite batteries. Panasonic stays at the forefront of battery technology, and its revolutionary batteries allow them to charge faster than ever before.

These batteries have been specially designed a pioneer in the electric vehicle space in partnership with Pansonic who is the manufacturer. Only recently launched in 2019 and still not widely available publicly, this battery is currently the highest energy density battery in the world. Our Flash graphene power bank is also the world’s most powerful 210W USB-C power bank with 20,000mAh capacity utilizing 4 x 21700 lithium polymer graphene composite battery cells.

What are the Graphene power banks?

Graphene power banks are essentially portable power banks enhanced with graphene batteries.

Graphene is the world’s most conductive material with ultra-high thermal conductivity, drastically increasing charging times. Instead of having to wait for hours for your device to charge, plugging into a graphene battery bank can take your device to full charge in just minutes. Our Flash graphene charger can have a full charge in just 1 hour and 10 minutes (20,000mAh) or 80% (16,000mAh) in only 35 minutes. making it 10 times faster than traditional portable power banks.

While traditional lithium-ion batteries are expected to last to up around 500 charge cycles, graphene-enhanced batteries triple this with an estimated 1500 charge cycles! Furthermore, a graphene battery’s lifetime is much longer than lithium-ion’s two to three-year lifespan.

Graphene batteries are an emerging technology. The material itself is a composition of carbon atoms tightly-bound in a honeycomb structure. It’s so lightweight, that this structure is a mere one atomic layer thick, essentially making graphene a 2D structure.

Due to the high production costs of graphene, power banks using graphene technology are relatively new and not widely mass-produced.

Do Graphene power banks charge fast?

Graphene offers higher electrical conductivity than that of lithium batteries. This means faster-charging cells that can deliver very high currents resulting in super-fast charging times.

Lithium-ion stores up to 180Wh of energy per kilogram while graphene can store up to 1,000Wh per kilogram. The ultra-fast charging times is one of the best and biggest aspects of graphene battery technology.

While there are technologies in place for fast-charging lithium-ion batteries, they still carry some limitations. Pumping in too much wattage could result in the battery breaking or even blowing up.

The difference with graphene battery power banks is that they can substantially shorten the charging time from zero to full. For example, a 3,000mAh lithium-ion battery can take up to 90 minutes to charge, while a graphene battery at the same capacity will charge in roughly a fourth of that time. Graphene is just better at handling higher wattages of electricity which sets them apart from lithium batteries.

What is a Graphene battery?

Graphene is a fantastic conductor of heat and electricity. Unlike lithium, that doesn’t fair as well when you put a lot of energy in or out of it, graphene is the world’s most conductive material. making it a game-changer for battery technology.

Graphene is very light, and even 5 sheets of it will only end up being 5 atoms thick. This means graphene batteries are exceptionally light and transportable. A perfect partner for portable power banks.

Graphene batteries are well-established and come in many forms. It can be used to power anything from watches to electric cars.

Are Graphene batteries the future?

These batteries are still relatively new and will take some time to become more widely available as the technology is still progressing. However, once they do, you can expect to see graphene batteries used in nearly all electrical appliances and devices.

In the future, graphene batteries should replace lithium-ion batteries. Big technology companies are aware of the limitations lithium has, and are already embracing ways they can begin manufacturing graphene batteries on a larger scale. For, not only are these batteries high-performing, but they’re also more environmentally-friendly than lithium-ion overall and can be much more easily recycled.

The biggest obstacle to overcome right now is the extremely high cost of manufacturing. However, as popularity and demand grow, production can become more refined and cost-effective. allowing the market to become more widely adaptable.

At this present time, one of the most viable ways to integrate graphene batteries into devices is by using it in conjunction with traditional lithium-ion batteries.

As such, major companies such as Tesla Motors, Samsung, and Microsoft are hinting at the development of next-generation graphene batteries that may lead us into the future advancement of battery technology.

With Chargeasap, you can get in on the action already with our existing graphene power banks set to change the way you charge!

How do Graphene power banks work?

Graphene power banks work in the same way as a traditional lithium-ion power bank, the difference is that with graphene-enhanced batteries. such as what’s used in the Chargeasap Flash. you will experience:

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-Ion Batteries vs. Lithium-Polymer: Which One’s Better?

Modern electronic devices use two main battery types: Li-ion and Li-Po. But which is best?

Readers like you help support MUO. When you make a purchase using links on our site, we may earn an affiliate commission. Read

Lithium-ion batteries power most electronic devices around the globe. However, you may have encountered certain consumer electronics with a lithium polymer battery.

While it might not be immediately evident, there’s a significant difference between lithium-ion (Li-ion) and lithium-polymer (Li-Po) batteries.

In this article, we take an in-depth look at these popular battery types and how they power the devices we use in our everyday lives.

What Are Lithium-Ion (Li-Ion) Batteries?

The lithium-ion battery powers smartphones, laptops, and numerous other devices around the globe. These batteries are made by combining four different components:

  • A cathode (the positive terminal)
  • An anode (the negative terminal)
  • A separator
  • Electrolyte

The anode is mostly made of lithium (thus the name), while the cathode is often made from graphite. Cobalt or manganese are often used as well.

graphene, power, banks, lithium, polymer, bank

The separator prevents the charges from causing a short-circuit, and the electrolyte serves as the medium that allows the ions to move from the anode to the cathode.

Thus, when you charge your phone, ions stored on the negative terminal begin to vibrate until they gain enough charge to make the journey from the anode to the cathode, overcoming the separating layer. This movement is what generates the electricity that powers your device. As your battery discharges, the ions move back to the cathode.

What Are Lithium-Polymer (Li-Po) Batteries?

A lithium-polymer battery is slightly newer than the conventional lithium-ion battery, and it wasn’t until recently that Li-Po batteries were introduced to smartphones. It’s one of the most promising alternatives to lithium-ion batteries.

The primary reason for this was because of their fast charging capabilities. Lithium-polymer batteries were originally used in older, clunky phones and were found in laptops. Modern devices, like drones, also contain lithium-polymer batteries. Because it’s so flexible and lightweight, lithium-polymer batteries are found in power banks too.

Just like lithium-ion batteries, Li-Po batteries also have an anode and a cathode. But, these batteries use a gel-like electrolyte instead of a liquid electrolyte.

That’s one of the reasons why they are generally more durable, and you don’t have to worry about the electrolyte leaking too. But, this gel-like material tends to get harder over time, reducing the ions’ ability to move freely, reducing the battery life span.

The Key 8 Differences Between Li-Ion and Li-Po Batteries

There are a number of differences between lithium-ion and lithium-polymer batteries.


One of the main reasons behind the widespread adoption of lithium-ion batteries is their low pricing. New technologies have virtually halved the price of lithium-ion batteries, and because they have been around for quite a while, it’s generally much easier to manufacture these batteries.

If you compare pricing directly, the manufacturing costs of lithium-polymer batteries are slightly higher. That’s why they aren’t commonly used in cheaper electronics.

Power Density

Power density refers to the amount of energy that the battery contains when compared with its weight. Therefore, a battery with a higher power density will have a longer run time.

Lithium-ion batteries can hold up to four times the charge compared with lithium-polymer batteries of a similar size. This makes them more desirable for use in compact electronic devices.

On the other hand, lithium-polymer batteries usually need to be encased in a hard or soft-shell cover. This further increases the bulk, which makes them unusable in smaller devices.

However, the scales may eventually tip as newer manufacturing methods are introduced.


Lithium-polymer batteries are generally safer than their lithium-ion counterparts, primarily because of their robust packaging. A hard-shell Li-Po battery can resist external pressure, which mitigates hazards.

That’s one of the reasons why most devices that offer extremely fast charging usually have lithium-polymer batteries inside. The electrolyte gel in a Li-Po battery is also less likely to leak than the Li-Ion electrolyte.

Passive Discharge Rate

A device powered by a Li-Po battery will discharge incredibly slowly. The passive discharge rate of Li-Po batteries is considerably low when compared with Li-Ion batteries, so you don’t have to worry about your device running out of juice while it’s not being used. In that, long-term storage of Li-Po batteries is easier than Li-Ion.


A simple reason for that is their customizable nature. You can buy Li-Po batteries in all shapes and sizes (due to their gel base), and several manufacturers have taken advantage of this freedom. You can get Li-Po batteries from 1,000 mAh to 10,000 mAh or higher! Some Li-Po batteries also have an incredibly thin profile, with a thickness of less than 1mm!

Useful Life

Lithium-ion batteries generally last longer than lithium-polymer batteries. An average lithium-ion battery can last two to three years, whereas lithium-polymer batteries have a much shorter life span. That’s because the gel-based electrolyte begins to harden in Li-Po batteries.

General Maintenance

Lithium-ion batteries require virtually no maintenance whatsoever. Li-Po batteries, on the other hand, require a bit of maintenance.

Many of the myths about phone charging are false. Smartphone software also lets you get more accurate battery information. For instance, you can calibrate your iPhone’s battery to know more about its general performance.

For instance, if you’re storing Li-Po batteries, you must charge them around the 30% mark before storing them. Similarly, larger Li-Po batteries require a specialized balance charger for charging.

Newer technology has now made it considerably easy to maintain lithium-polymer batteries, which is why they are now being used in smartphones.


Both lithium-ion and lithium-polymer batteries are quite portable. However, the former wins because you can easily find them in quite thin designs, which is why they are often used in smaller consumer electronics.

Li-Ion vs. Li-Po: Which Is Best?

Lithium-ion batteries are more common because of their widespread adoption. However, lithium-polymer batteries are fast becoming popular because of their increased safety features and stable performance.

However, many companies are now working on newer technologies. Solid state batteries, for instance, outperform lithium-ion batteries in virtually every department, providing a more promising alternative.

How is a Power Bank Made How Does It Work?

Power banks have become widely popular because of the use of battery-powered electronics like our smartphones. Some batteries just aren’t powerful enough to go all day without needing a recharge, so power banks are often a necessity! The real question is: How are these portable chargers even made? We’ve got the power to show you exactly how the mighty power bank was made, along with some helpful tips and tricks to keep yours in perfect working order. This small mobile accessory packs a large punch!

What is a Power Bank? Top

A power bank is a portable charger that works on battery-powered electronics. Power banks can recharge smartphones, tablets, laptops, and Bluetooth devices.

You’ll find power banks in a variety of shapes and sizes, both with and without a wire. These chargers are a good backup if you lose battery.

How Does a Power Bank Work? Top

A power bank is a wireless battery that can receive and produce charge. For a power bank to work, it must be charged to store energy. First, an adapter cable provided with the power bank is used to charge it with a wall outlet. Once the indicator light on the power bank shows the accessory is charged, it can be used to charge electronic devices.

The energy stored in a power bank is then transferred through a charging cable from the USB port to the device.

Step 2

graphene, power, banks, lithium, polymer, bank

Assemble the Circuit Board

Next is the Printed Circuit Board Assembly (PCBA) where the electric components are soldered on to the circuit board. A circuit board is the brains of a power bank.
Step 3

Solder the Batteries

The batteries are soldered to the circuit board by the terminals. The newly conjoined circuit boards and batteries are then sent down a conveyor belt for the next step.
Step 4

Test the Power Bank

A DC Power Tester is used to determine the current and voltage of the power banks. The power bank is tested through the USB and USB min ports on the circuit board.
Step 5

Add Protective Housing

The battery and circuit board are encased in protective housing made of aluminum or ABS plastic.
Step 6

Test Electrical Connections

CT100 testers are used to check the electrical connections in the power bank. The chargers are checked to make sure they can receive and produce a charge.
Step 7

Test Battery Capacity

A burn-in test is performed to monitor the battery capacity of the newly produced power banks. Hundreds of power banks are charged at once for several hours.
Step 8 (Optional)

Add Label and Design

Labeling and design is added to the power banks using screen printing, pad printing, or laser engraving.
Step 9

Final Visual Inspection

The power banks are given one final visual inspection before they are packaged and shipped to the destination.
Step 10

Ready to Charge Your Device

Check out how power banks are made in this video! Top

And there you have it! The simple process allows large quantities of power banks to be made at once for a lower cost. You now know how your power bank came to be one of your most important tech accessories.

What Is the Lifetime of a Power Bank? Top

The average working life of a power bank is between 200 and 1000 cycles. A cycle is one charge of the device, either partially or fully. The average lithium-ion battery inside power banks will start to lose their capacity after so many charging cycles. Larger power banks require less charging cycles, so they will last longer than smaller power banks.

There is no guarantee to how long your power bank will last, but reducing how often you use your power bank can make it last longer.

What Can a Power Bank Charge? Top

A power bank can charge just about any electronic device that has a rechargeable battery. Devices that normally use a USB charger can be charged with a power bank!

A power bank can charge the following electronics:

  • Smartphones
  • Cameras
  • GPS systems
  • Gaming devices
  • Laptops
  • GoPros
  • MP3 players
  • Tablets

If your device does not have a USB interface, you might still be able to use a power bank if wireless charging is a feature of both the device and charger. Before using your power bank, make sure that it provides proper voltage to adequately charge your device. You can always check with the manufacturer of your device if you are uncertain.

Can a Power Bank Charge a Laptop? Top

Yes, a power bank can charge a laptop, but only if it is the right kind! Unfortunately, you won’t be able to charge your laptop with just any power bank, but there are certain types that can keep your battery charged.

Most laptops can be charged with a USB-C port. If the charging cord provided with your laptop has a USB-C, then you can use a power bank that also has a USB-C output to charge it.

Once you have the correct cables, you’ll want to make sure your power bank will deliver 30W of power in order to charge your laptop. If your power bank has fewer watts, it won’t be powerful enough to charge your laptop and could potentially drain your battery.

The following manufacturers make laptops that are USB-C compatible:

If your laptop does not support USB-C charging, you’ll need a power bank with a 12V output and a cable that fits the laptop’s charging port. If you are unsure if your power bank can charge your laptop, you can always reach out to the manufacturer!

Why Are Some Power Banks Expensive? Top

Not all power banks are created equal, especially when it comes to price. Some power banks are more expensive than others because of how they are made and their charging capacity.

Higher quality power banks are more expensive because they last longer, have a more powerful battery, and are made with high quality materials. A more budget-friendly power bank will still charge your battery, but it may be smaller or not hold a charge as long.

Do Power Banks Ruin Your Phone? Top

It is possible to damage your phone’s battery from using a power bank. However, if you are using your power bank correctly, you significantly decrease the odds of ruining your phone.

Here are some of the ways a power bank can ruin your phone:

  • Using a low-quality power bank
  • Power banks with insufficient voltage
  • Overcharging your phone

Using a Low-Quality Power Bank

Low-quality power banks aren’t all guaranteed to ruin your smartphone battery. However, if you are using it frequently and for long periods of time, it can cause damage to your phone’s battery by making it lose its charge faster. The best way to avoid this is to make sure you have a high-quality power bank, or to use your lower quality charger only when you need it most. Lower-quality power banks usually have small batteries, are low-cost, and provide insufficient power to your devices.

A Power Bank With Insufficient Voltage

The power bank you use to charge your phone should have 5V. If your power bank has less voltage, it can drain your battery instead. If your power bank has a voltage greater than 5V, it can damage your phone by overloading the battery. Be sure to check the voltage of your power bank before using it to charge your phone.

Overcharging Your Phone

Power banks aren’t designed to be constantly plugged into your phone to keep it at 100% battery life. If you constantly charge your phone, your battery will not be able to hold its charge for long periods of time. It is best to use your power bank sparingly and to unplug it from your phone when it’s close to being fully charged.

Following these tips will allow you to use your power bank without fear of damaging your smartphone! The best rule of thumb is to use your power bank only when you absolutely need it, and to unplug your phone after it has enough battery.

The Bottom Line

Power banks will always be a necessity because they provide the energy our phones, laptops, and tablets need each day. Through their simple manufacturing process and their capacity to charge a variety of devices, power banks are the ultimate tech accessory!
