any one knows how to connect Varia Headlights to an external battery (powerbank) and have lights on (if it's possible?)
I always have a powerbank on me and sometimes forget to charge my lights... plugging the powerbank to the light seemed to be the obvious thing to do when low on battery, but it seems the varia headlight can either charge OR light, but cannot do both at the same time...
so once the light is dead I'm left with no light and a full source of energy I cannot use... :(
or is there a trick to it?
