I have dual-input 26800 but I'd add more weight than my current setup so it stays home. The dual-input arises due to 12W limit of Type A, and yet we're carrying TypeA cables anyway for our MicroB Anker products.
I'd rather Type C and a smaller products, 1 C is smaller than 2 A.
That 268000 idea however can suit a totally different situation of you go with no charger at all and 26800 lasts 2 to 3 days with all these gadgets when you removed those it would end up, yes, a workable solution as you got 3 ports out. But this was 5 nights so 26800 not ideal.
