Indipro D-Tap to Type C-USB Quick Charging Adapter & Power Supply (10")

This product is so well built and the finish is absolutely amazing. The shinny metallic red matches well with the GDU V mount battery too.

Most importantly it works and provides Power Delivery to the Canon R5C via D-Tap. It allows any V mount Battery that has D-Tap to be used to power any devices that requires USB Type C.

This product so far is unmatched on the market. Highly recommended and couldn’t be happier.

What impresses me the most about this adapter is its fast charging capability. It delivers efficient power to my devices, allowing them to charge rapidly, even during demanding shoots or when time is limited. This feature has been a game-changer for me, as it ensures that my devices are always ready to go when I need them.

I've used the TetherTools/ONsite adapter, and I currently have the Jupio PowerHQ and this.

The TetherTools is unidirectional (only does DTAP-to-USB) and is finicky in terms of what devices it will negotiate PD with. I wouldn't use it on a job unless I had a PD meter to verify that it was working, and some backup supply to use if it failed, which means I just didn't use it.

This and the Jupio are reliable (negotiate PD with every device I own within their respective current limitations) and provide bidirectional conversion (DTAP-to-USB and USB-to-DTAP). The IndiPro has two advantages: It can go up to 100W vs 60W for the Jupio, and it can safely fast-charge LiIon batteries over DTAP, while the Jupio only acts as a DC supply.

EDIT: I've also tried charging a range of IndiPro, Smallrig, and Fxlion batteries from 50-150 W*hr with this, using a USB-PD power meter to check the delivered power/current. Both the charging currents and the current "step-downs" look reasonable. It delivers 100W to the larger ones and limits the 50 W*hr batteries to 60W (this is a good thing). It appears to step down by about 1/3 at 80% and then progressively ramps the current down to zero from 90%-100% (again, a good thing unless you really like fires).
