Is it possible to charge Explore 2 with external battery (via USB-C port) during workout / navigation ?

Hye,

Sorry if question has already been posted, but I can't find answser anywhere.

I want to buy an Explorer 2, and sometimes I will do bikepacking all day long. The battery won't last enough and I wonder if it's possible to charge it during navigation without stopping the workout ?

Thanks for your answers ;-)

Fred
