ID 12 volt pins, please

I have a 12 volt power supply. I can charge it but would like to use it to have back up power that has a USB port, like a cell phone or a camera. Can someone ID the pin connectors in the pic? Bonus points to where I can get and adapter fror that pin to a male USB pin....

The first picture looks like a pretty standard 2.5mm barrel jack. I get 12VDC power supplies from powerstream.com, myself, but Amazon has them too.

The second is tough to tell from the picture, but it looks suspiciously like a micro-USB.

So are you looking for some kind of adapter that will supply 12VDC through a micro-USB? My knowledge of this is limited, but I thought USB was limited to 5VDC, so I'm not sure how that'd work.

What am I missing?

I wish to power a Garmin dash camera beyond the 1 hour internal battery life. The unit has the 2.5mm barrel jack. The Garmin plugs into my cig lighter and uses straight 12volt power.

I want to use the Garmin on a bicycle and the ride would exceed the 1 hour life of the internal battery.

That adapter just provides the mechanical connection between the USB device and the power source jack - so your 12V supply still needs a converter. The fleabay description states:
TypeC Female Jack Plug to Mini USB Male Power Charger Adapter
Use any 5V, Multi-voltage charger to power your device
Note:You must make sure power supply is correct voltage for your device.
This adapter DOES NOT come with any power supply - It is an adapter tip ONLY.

I think this is what you are after - just cut the jack from your PS and make sure to observe polarity of the 12V connection wiring:

This is the power supply. 12.5v output, like my ciggy lighter. BUT I will be on my bicycle.....no battery and no engine.
