This is 30% off RRP, not sure why it is that much more expensive than Xiaomi ZMI 20,000mAh PowerBank which also has PD.
From a brief skim of the specs,
Cygnett has 45w output for PD VS the Xiaomi as maxed at 40w.
Total output for the Xiaomi is 45w VS total output is 63w when all ports are used for Cygnett
Not sure why that would mean this cost double the price of the xiaomi.
Either way if anyone has the $$, costco seems to be the cheapest place to buy it right now.
Review seems good;-
