A 10,000 mAh version is offered for $ 90, and a 100-watt power supply will cost $ 15.
We have heard many times that smartphone manufacturers plan to use graphene batteries in their smartphones, but so far no company has introduced such devices. The situation may change very soon.
The American company Real Graphene is working on batteries with improved characteristics, which, according to company representatives, are almost ready for mass commercial use. The main advantage of a graphene battery is that it charges very quickly.
Real Graphene CEO Samuel Gong noted that it takes about 20 minutes to fully charge a 3000 mAh graphene battery using 60-watt charging. This is several times faster than the modern batteries of most smartphones are charging.
He added that most of the batteries of modern smartphones withstand from 300 to 500 charge cycles without a significant deterioration. And Real Graphene batteries can withstand about 1,500 cycles at the same capacity. Since the graphene battery generates much less heat, it is cooler and safer.
