Hey, 

i was Set up for a 10 Hour Timelapse when after 2 Hours my sl2s my camera showed me the red battery symbol although I hat the camera on a powerbank with usbc . 
 

why? 
 

have I missed something? 
 

i thought the usbc port gives me constant power?

It will change when camera is off.

there is only a trickle charge when the camera is in use.

I guess I found the problem. You need a usb c source. If you use the standard usb for the powerbank it trickle charges. But if you use a Anker usbc powerbank with both sides usbc then the plug 🔌 sign comes up and the battery is charged. Very disturbing ….
