I know this has been asked but I can't seem to find a definitive answer as in which exact Powerbank can support Cosmos.
Cosmos uses 21W battery. However out of all the QuickCharge 3.0 batteries I've checked, all of them only provides 12V 1.5A which is 18W.
There are some batteries offering higher W but those are PowerDelivery standard, but not QuickCharge. And I'm not sure if Cosmos supports PD.
So down to the very question. Which exact brand and model number of PowerBank have you tried and can be 100% certain that it support Cosmos?
NOT talking about OG Vive.
