My guess is that your USB battery outputs slightly under 5V - any way to test the output voltage?

I used a digital meter to measure voltage at the micro usb end (pi end) on the cable in question and it was 5+Volts - Pi not under load/plugged in. To get a measurement with the Pi3 on I will have to fashion a cable allowing me access the +- leads. Remember this is all bolted/screwed into a case for portability so I cannot easily access the Pi itself. If I have to I can disassemble to get the readings.

Smaller/larger power wire cables will help (scroll up to read my treatise on USB power cabling).

Thanks. I gave it a read.

This does not always happen. I would think that if it were a power issue then I would see this as a continuous event (I just brought the Powerbank up to full charge), but this seems to occur randomly.

Ideally, you want to take the measurement inline - I second the recommendation for one of those inexpensive inline USB power meters. I have one made by DROK:

ok. ordered one. should be here Friday.

oh, I added a bluetooth speaker to the Pi3 in question yesterday. The bluetooth built-in works quite well. The speaker I purchased can really push some sound/volume.

Here you can see how fast a ODROID-C2 can be:

(only take a look at the last task's and ignore invalid's, these where produced while I'm working on the App)

It's a standart C2 with no overclocking running a optimized App-Version ;)

That is amazing! Are you running Android or Ubuntu? Are these CPU or GPU tasks? What, specifically, does "optimized App-Version" entail/mean?

I'm running Odrobian. But

I'm running Odrobian. But Ubuntu should be fine too.

It's an "normal" CPU-Version compiled for AARCH64. I've rewritten some part's of the code to get it vectorized and take "full" advantage of the neon.

This is still not finished and there is still a lot of room for more. :)

N30dG:

I note that you are running two machines on odrobian. Are both machines Odroid-C2s? and if so why the difference in times 24k vs 14k.

Yeah, both are C2's the 24k

Yeah, both are C2's the 24k one using an old App-Version.
I don't wan't to change this now because the device is computing a Wisdom. And I don't wan't to touch this until it's finished.
