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 batt ery?

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:

• Larger battery capacity: with 5x the battery life of an iPhone 11
• Faster charging: Single USB-C port supporting 100W USB-C Power Delivery for devices including MacBook 16"⁣. Both additional USB-A ports support 18W QC3.0 and 40W Huawei Supercharge, Oppo & Vivo Flash Charge⁣
• Cross-compatibility: 150W output charging 4 devices simultaneously 
• Lower temperature:  Flash will never go above 50°C (122°F) unlike competitor power banks which can reach 70°C (167°F)
• Pocket-sized lightweight device: Despite all the power, Flash comes in a pocket-sized lightweight 470g (1lb)
• Apple Fast Charge: for iPhone, Airpods, and Apple Watch
• Qi Certified Wireless Charger
• Apple Watch Wireless Charger
• Pass-through charging
• 5+ years of battery life

Graphene as a material, can improve such battery attributes as listed above and help power banks achieve greater optimization and performance. For anyone reliant on their daily device and requiring super-fast portable charging, a graphene battery power bank is your answer.
