This page from Meta helped me
https://www.meta.com/de-de...Info: The Elite strap with battery will not fully charge if it is not connected to the Meta Quest 3 or Meta Quest 3S
and this charger (the charger must have power)
Roline USB charger 4 ports 120W, 2x C + 2xA QC, article number 39230344
and this Meta charging station
Meta Quest 3 charging station, article number 38866204
and the latest Meta SW must be installed
Attention! The Elite Strap must be connected to the headset and the charging cable must be connected to the Elite Strap for charging
This is how it works best in my VR installation and with the charging cradle.
