There are 3 popular types of need:
- Apple lightning
- Qualcomm QuickCharge
- USB and its evolution of USB-C and USB-PD
It has been a while since QC3 released, QC4 is around the corner so its logical for Anker to not have released any further QC products for a while and for more USB-PD and Lightning products.
I expect QC4 products will emerge.
