Hey all.
Anyone know if I'd be able to use this cable to run my exposure strada off a generic power bank battery? Or at least extend the run time of the light by trickle charging as the light was in use?
I see that exposure sell an external battery pack but it's expensive and I already have a couple of 10Ahr power banks.

I’ve done that with a cheap Anker power bank and a Joystick for BB 200 in 2018 and it worked fine.

It works fine, it's what I use to back up a small Strada 600 I have. Got the USB charger cable to charge off a power bank and a Boost cable so the light battery can back up the GPS if needed on shorter 1-night trips when I usually don't take the power bank.

This is good news! I found I already had the cable, must have come with the light and I have 20Ahrs of power bank storage. Nice bit of flexibility for charging GPS and phone too.
Bring on winter!
