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…
be sufficient?

Ralf
Ooh, this looks nice!
Thanks for all the replies, guys!
I see that even the RPi accepts any regular USB charger battery,
of which there are compact models available.
And the ODROID also has a compact battery accessory.
I've been through a lot of different effects products over the years.
I'm a proud 20-year owner of a BOSS SE-70 professional rack-mount
multi-effects unit. Your effects unit becomes like an extension
of your character and playing. Difficult to recreate. When you try
other units, it's like, whoa - I can't play this thing...
I've been reading other owners' laments about nothing really replacing
the SE-70's 'character', but the battery powered GT-1 seems close.
I have a Line6 Pocket Pod, which is great at simulating amps,
but not so great with the distortion and overdrive.
Actually I don't think it even has a distortion or overdrive stage,
just the amps. I wonder if anybody's hacked the thing by now...
But I know that if there's one application that should do
what I need it to do - it's Guitarix. Thanks to Hermann.
I had been using a portable product which has a 10AHr SLA battery
and a built-in stereo amp and an LED light, plus two AC inverter
outputs to power my non-battery effects gear (like the SE-70).
But, meh, kind of heavy and battery never lasted and now it's dead.
So now I'm evaluating a Roland Micro Cube amp.
The built-in amp simulations are, well, OK but with my SE-70
it sounds great, I like it.
I just need to find a good battery powered effects unit to take
the SE-70's place.
Or go back to running everything from a battery powered inverter again.
Thanks.
Tim.
