A power bank is just that. You make a deposit (often taking up to 10 long hours) and withdraw some of that to charge a device. The Graphene Polymer power bank is very different.
For starters, a 10,000 mAh Li-ion battery in a power bank usually takes 5-10 hours to charge. A Graphene Polymer (explanation here) battery takes 30-60 minutes! Although it uses a special 9-24V charger to achieve this.
Very recent advances in Graphene Polymer batteries allow electric vehicles to increase the distance from 400km to 800 km. It occupies between 20-30% space less than a lithium battery and can charge in a fraction of the time.
Next, conventional Li-ion banks have a hard time delivering fast charging 5V/3A, 9V/1.6A or 12V/1.5A charging. Graphene-based banks can deliver Qualcomm 3.0 Quick Charge at whatever amperage is required. Although it does need a special chip to monitor power delivery. The chip monitors over and under voltage to ensure the recipient device battery remains at best health.
