Hi,

"The ODROID-C2 consumes less than 0.8A in most cases" -
http://odroid.com/dokuwiki/doku.php?id=en:c2_hardware

The ESI UDJ6 and ESI Maya 22 USB are bus powered, unfortunately
downloading the data sheets from the ESI homepage doesn't work for me.

"the voltage at the hub port is specified to be in the range 5.00+0.25
−0.60 V by USB 2.0"
"High-power devices draw at least 1 unit load and at most 5 unit loads
(500 mA)" - https://en.wikipedia.org/wiki/USB#USB_2.0

So IIUC required are likely around 1,5A at 5V, for at least 2 hours.

Would be a battery as recommended at

https://electronics.stackexchange.com/questions/98896/good-portable-5v-1-5a-power-source

be sufficient?

Regards,
Ralf
