This part across the newer Powercore has been puzzling me. The Powercore 10000 PD had 18+10, but then subsequent Powercore then became 18 or 10 or both 12. The 18+10 I own, I metered it, it also did not overheat, so Anker knows how to make it, and they choose not to. Cost? more warranty claims? The 10000 PD Redux removed some of this.
Give Anker credit here. 18W from a single cell is a success.
Truth was there was never a need for C input for this, its input is the wall.
GaN would not really have helped in this product. The fusion of a cell within one encasing was always going to be struggle. The most impressive part is 18W out from one cell. I assume it is the same 26650.
If they know how to make 18W from 3.7V then expect a 30W PD Powercore 10000mAh in next months.
