I am starting this thread more out of curiosity than anything else. One of the great things about the new GR III is that it uses USB-C port for charging/connection, which is standard and huge improvement over proprietary connectors. I have bunch of USB-C chargers/cables lying around and carry some with me wherever I travel. The camera also comes with adapter which will charge the battery in camera, and I believe pretty much any USB-C charger will do that as well.
But, to get to my point, some chargers (or external batteries) can do more - Ricoh also sells AC power adapter, K-AC166U, that is able to power the camera, even with no/empty battery. Other chargers have this capability as well, and you may already own them.
Update: It seems that any charger/power bank supporting USB power delivery will work. I will try to keep the list bellow updated with known devices, especially since in many cases the fact they suport PD is not obviously stated, but any device supporting power delivery should be fine. So, here's the list of chargers/power banks that will work as AC adapters for GR III:- Original Google Pixel charger (TC-G 1000 US) - sold as Google 18W charger here in the US
- Dell laptop USB-C port (XPS-15)
- Lenovo 65W adaptive charger (for a Thinkpad X1 Yoga laptop). Model No. ADL65YDC2A
- Anker PowerCore 10000 PD, 10000mAh Portable Charger USB-C Power Delivery (18W) Power Bank
- Samsung Galaxy Tab S4 - yes, the tablet will actually power the camera, while allowing file transfer at the same time
Note that while power output of the adapter may play some role, this is about more than just power rating of the adapter. Samsung adaptive chargers, which are also capable of providing 18W power, will not provide AC power to GR III.
I'll be glad to add more to this list. I don't think that the ability to power this camera externally matters that much for camera like GR III, nobody's shooting with it long sessions in studio, but it comes in handy for things like transferring lot of photos via WiFi to my phone while traveling or just experimenting.
How to test this:
- Remove battery from Ricoh GR III
- Plug the charger to be tested into the camera
- Press power on
If the camera powers on in the last step, you're in possession of an AC adapter providing full power to your GR III. It will also show plug on the screen where the battery indicator normally is. Note that you don't need to remove the battery for normal use - I just consider it a more clear proof than simply looking for the plug indicator.
Disclaimer: Do this at your own risk. While I strongly believe that USB-C is standard for a reason and no civilized USB-C charger should damage the camera, if you end up creating a black hole, I won't be responsible.
