Does EVA1 USB Port Send Power to Accessories?

There are some third party batteries that have an extra power output plug - such as

or

(Neither of these is 5v USB power, so you'd probably need to adapt...)

Though the camera itself does have a USB 2.0 Host plug, I personally wouldn't use it for power. (Plus I keep my wi-fi adapter for linking with the ROP app plugged into it all the time.)

If I needed USB power for something I'd probably rig up one of my inexpensive USB power portable chargers (there are some small ones that look like a lipstick tube and weigh almost nothing) and attach to my cheese plate or off the back of the handle.
 
Thanks. I was hoping the host port could power a FF and/or wireless HDMI. Those sound like viable options, too, but for future projects, perhaps. For now I'll stick with a manual FF.
 
The USB port on the EVA1 is not meant to power such devices. It is designed to power the WM50 wifi adapter or one of several USB-to-Ethernet adapters available from 3rd parties.

Separate to that, the Nucleus N is not best powered by a 5v source. It is rated from something like 4v-17v, and if you power it off a 5v source the motor will be slow to respond and may not have the power to push many lenses. It is much better working from a 12v o 14.4v power source. At my request, Indypro Tools makes a Micro USB-to-PTap cable specifically for use with the Nucleus N. This works great for the motor and if you get a pair of cables it can also be used to power the hand controller.

If you wish to keep the EVA1 kit very compact, CoreSWX makes a battery that mounts in the EVA1's battery slot and features a 12v PTap out the back. That PTap is rated at 20w of draw, which is plenty to run the Nucleus N.
 
I have lost two EVA Core batteries due to them shorting out from a single Nucleus motor. I contacted the manufacturer and was told that the battery's max output is 1Amp (12w). For reference, 20w=1.66A

Would that be the regular Nucleus motor or the little motor that comes with the Nucleus N? The Nucleus N motor is much smaller than the regular Nucleus motor.

I've had some issues with CSWX batteries in the past and they were always good at addressing them/fixing them, but I'd raise some hell over that. They list the specs on their website as 2 amps/24w for the power tap on the Panasonic compatible batts.

A normal power tap on a "big battery" or battery plate is at least 10 amps.
