StanD, I will try a Samsung 1a charger and report back.

I have a 2.1A Charger that I got at Bestbuy, think it's a Belkin, which works. Did you try to take the USB plug out of the E18 and plug it back in after a around 4 hours?
Thanks. I ask because I'm picking between the E18 and E12. I have a Beyer DT880 250Ohm so I'm afraid the E18 doesn't have enough power.
Works with the Moto X (Android 4.2.2 on Sprint).
Does not work on the Nexus 7s (2012 and 2013, both on Android 4.4) or the Galaxy S2 (Android 4.0.4 on Sprint).
Unfortunately we won't be getting a batch of devices in at work as I had hoped.
I'll be curious as to what you find, I have an E12 and E18. I was pleasantly surprised that the E18 can drive my 300 Ohm Sennheiser HD600's, although not as loud as the E12 can, still plenty loud. It may come down to the sensitivity of your cans.
The updater shows no new updates, and it's a QA testing device (belongs to my work) so it needs to stay stock. Sorry. I do have an Infuse running Avatar Rom (mix of CM and MIUI) and that didn't work either, but that's from the previous generation, IIRC.
After the 7hr charge with a Samsung 1A charger, I was able to get 13 hours as a dac/amp before plugging back in. That's with it not shutting off so it wasn't completely drained, although at the last battery LED for quite some time (probably not the most accurate gauge). Looks like my belkin wall charger might not be a good port for it.
I'm listening to the DT880 now on the E18 and drives it to satisfactory levels.
Once past volume 7.5 on the pot, the volume doesn't increase. Gain on low at 7.5, the listening level is just right. If you want a little more energy, setting the the gain to Hi offers a good increase to what I would call borderline loud to hearing damaging. At vol Hi8, you can tell the amp is maxed with clipping but that's beyond safe listening levels (preserve your hearing!!). Definitely at the peak of what the amp can push, a little more headroom would be nice but to most and what it is (portable first, desktop second) it's plenty decent at normal listening levels. You're not however going to get the SQ of a better amp with separation, timbre, and soundstage.
