I've been researching for ages but struggling to tell what's the exact best product. Ideally I'd like a combination of products that allows for usb c charging (to be seen primarily) that feels tightly integrated into the Brompton. I like the fork integration of the official light but would prefer usb c charging. I can more easily find appropriate mounts to attach to the screw on the back of the saddle. I've seen AliExpress brackets that use GoPro style mount holes then you adapt to Garmin/Cateye or whatever but I haven't seen photos of them in use and I've read they can interfere with the luggage block. Ideally someone else would have a combo of products that I can see works aesthetically and practically and I'd just get the same.

What do people here use?
