Panasonic GH2 powered via USB battery

I'm already using a 3600mAh external cellphone battery that outputs 5V USB power to run my Zoom H4n audio recorder for extended recording times.
Recently I found a 10'000mAh battery that not only has 2 USB outputs but also a third output that can be switched to 12V or....9V.
Perfect to run the GH2 camera!
It turns out that even the proper adapters are already included and have the polarity required.
Here is what I used:
The original batteries are 7.4V 1200mAh. The power bank is 5V 10000mAh.
This is about 5.6x the capacity of a Panasonic battery for this camera.
Of cause it will be significatly less of this device also powers the Zoom H4n and 1-2 phantom powered microphones through it.
...or multiple GH2 cameras from one power bank.
...or something else that runs on 5V USB power from the second USB port. (Arduino? Video light? ...)

Hello Marcus!

Nice! So it is OK to run the GH2 with just 5V ?? Or were you using the 9V out?

Pls advise, thanks!

Hello Marcus!

So you were using 5V out for the GH2 ??

Or did you have to plug 9V for the camera to work. I plan to get one of those too!

Pls advise, thank you!

9V for the camera
5V for the Zoom H4n audio recorder
(and a second, unused 5V USB left)
