Great, thanks for sharing!
How about a second USB connector for powering two devices in parallel (with one 26650 Li-Ion) and a holder to mount it on a bicycle ;-)
That is exactly what I'm searching for.

That tiny boards have only one connector, but its easy to build a USB 'Y' cable. Regarding the bicycle holder... try to search for some universal adapter here, there are bicycle holders for almost anything, maybe you find some compatible, in that case post here a reference. If you can't find any, post again, I'll try to get the time to design it. Thanks for the feedback!!

Thanks for your reply.
I was already working on a similar solution but based on the 18650 batteries using some small PCBs from China when I saw your case here and thought, give it a try. Maybe he has a need for the same solution. In my case to power a GPS receiver and a mobile in parallel on my bike. If I had success, it would have been the faster solution, now I have to continue my work ;-)
By the way, I don't like the Y-cable solution. I prefer to have a 5 V regulator for each device.
For my case design I havn't found a secure solution to mount the little PCBs now.
Anyway, thanks again for your support
Here are links to the PCBs I mentioned:

The Micro-USB board and the one with Mini-USB connector are alternatives
