<div dir="ltr">According the their website it is 1.5A max <a href="http://www.ianker.com/support-c1-g228.html">http://www.ianker.com/support-c1-g228.html</a> which would put us at 10 hours for a full recharge, without draw on it. Again this isn't a tradition UPS, but something that we can put to use because of the low draw of our server :-)<div>
<br></div><div>I am sure the 5volts can be provided by either an AC -> 5volt DC coverter or a 12 volt to 5 volt DC converter. I have a 12volt to 5volt 3amp converter in my car that can charge two modern cell phones. Those electronics are pretty cheap thanks to smart phones.</div>
<div><br></div><div>Until I know what drives we are using most of this is speculation. The IMX6 SOC has very intricate control over the power states of the hardware. If we know we are in a battery use situation we can limit the number of cores powered on and various other things. Out of the box we are doing dynamic frequency scaling and various cpu idle states to minimize power usage.</div>
<div><br></div><div>I don't believe there is anything out of the box that will tell us we are on battery power. However the cubox-i does have an IR input. Perhaps replacing the LED notification lights on the battery pack with an IR emitter could work for us? I am not sure what the Cubox-i has inside for GPIO, I don't think much. That is why switching to custom boards in the future would give us a bit more flexibility.</div>

<div>this is a nice idea. the input says 5V 1A max and we want to supply
5V 2A for 7.5 hours. does this mean we need another 15 hrs for
charging? how do we supply the 5V input, from AC or 12V.</div>
<div> </div>
<div>of course it would be nice if we could sense the charge level in the
charger device and shutdown when it is low. I know that is one of George’s
pet projects.</div>

<div>are there low power states we can put the drive (spin down) and the cubox
(sleep) into?</div>

<div>That is a 15000mAh battery. </div>
<div> </div>
<div>That means that we can run at 2 amps for about 7.5 hours on battery.
Not too bad.</div></div>

<div dir="ltr">All we need is 5volt DC in, preferably 2amps minimum. If
the drives aren't too power hungry then they should be able to be powered by
the eSATAp connector, although I haven't tested that. I will actually
ask Rabeeh if he has tested it. I know he has tested eSATA just don't
know if it was self powered. If we can't get eSATA to power the drive
for whatever reason then a USB port should be possible. A lot of older
eSATA cases would require a usb plug for power, if they didn't support eSATAp.
<div> </div>
<div>Most of this depends on the draw of the drives. If we want a
battery backup solution then we probably want the larger case I posted a link
to earlier and then a battery solution that provides two 5volt 2amp
outputs. I am pretty sure I saw one on Amazon.</div>

<div>Do you guys have the models of drives you plan on using for
storage? Time to run some numbers.</div></div></blockquote></div>
