Qualcomm QC is over-represented in the Anker product line. The nice thing about the 'ole 10000 was it was minimalist and focused on simple density, probably its nearest siblings below is the Mini+ and the Slim 5000 to go down in size or a different shape. Then going in size there is a performance drop for recharge til you get to the 26800 with its dual input. So the density focused products with balance of recharge time, have basically just 4 products, out of dozens.
Please, not another QC product.
The Powercore II 10000 is bloated, it is physically larger, heavier relative to its Wh and has performance which some don't benefit from (basically if you don't need QC) so if you don't have QC (so that's Apple and a lot of the Android community) its just bigger heavier more expensive for no benefit.
We need a successor to the 10000.
With Apple picking USB-C, we need USB-C better represented, I'd say like a USB-C 10000 with say 15W output, 10W input. Or, at most, a dual port 10000mah, with say one USB-C for input and output and a USB2 for output to "legacy" devices (like Anker's Sound products which really need to become USB-C too).
