I wonder if using a 15w or 18w battery for Cosmos will do any damage to the headset or wireless adapter. @lamyipming You'll need the Cosmos-specific 21W battery that comes with the Cosmos wireless attach kit to power the Cosmos. Quick charge is an intelligent charging system - the device and the host communicate with each other to negotiate current. If the host cannot supply the requested current, the system generally kills power flow between the two devices. If using an underrated battery, the HMD should shut down or not start at all (the behavior may vary a bit depending on the specific battery).

lamyipming Posted December 24, 2019 Share Posted December 24, 2019 So I've done some testing, in case anyone wants to know how to switch to wired when the battery dies and don't have a spare battery Using original link box power cable L1 of course can power the wireless adapter on the headset, but the problem is that the cable is relatively short so you can't really move around. Using a PD power socket together with a quick charge USB cable that can support 3A current cannot power the wireless headset. Seems the headset doesn't recognize a PD communication even though it can support up to 50W. Using a Quick Charge 3.0 socket plus a 5 meter USB 2.0 Type A to Type A cable cannot power the wireless headset. Using a Quick Charge 3.0 socket plus a 5 meter USB 3.0 Type A to Type A cable CAN power the wireless headset. I have tried to use this combination to play beatsaber for an hour without problem. So Quick Charge 3.0 seems like a must. Also you need a USB 3.0 blue cable. I guess length is not a problem. 1 Link to comment Share on other sites More sharing options...

I think the main issue is the battery can overheat if a device tries to pull more power than the battery is rated for. Link to comment Share on other sites More sharing options...

HoZy Posted February 3, 2020 Share Posted February 3, 2020 (edited) I use the Anker Powercore Speed 10000mah & 20000mah Batteries as they are output 2A @ QC3.0 12v (24w) Be careful a lot of QC3.0 batteries only output 1.5a @ 12v and are only 18w The original cosmos battery is 1.75a @ 12v so 21w and that's what is recommended.
