And you can use the USB adaptor that came with your iPhone/iPod plugged directly into wall too.
500 mAH is the safest bet (USB Standard). Charging at a higher rate might impact the battery life and the longevity of the battery in the long run (although your unit may charge faster as a benefit).
Anybody tried the AK120 paired with the Audeze LCD-X or XC who can advise if a good match, with 22 Ohm it seems like a perfect match in view of the 8x rule but worried it might drain the battery as they apparently are power hungry...?
Ak120 impedance is 3, and it is a terrible match for LCD's which require a powerful amp. Ak good for IEMs very bad for most full size cans, especially planar Magnetics.
Can't say I tested many, so I probably should say from what I read. Planars are a no, no for sure and I've heard Senn 650s are also not a good match. One day I will try plugging in my LCDs and see.
If you search what Vinnie Rossi of RWA, says about AK and full size cans it is the same thing as I did. He is an expert and very well thought of in the Audio world.
The AK is a stellar product for IEMs.
True, just that Audeze does confirm that they should be easier to drive and actually mentioned that they are ok with portable devices compared to their previous models and also other Summit end headphones, thought it would be interesting to know if AK120 could get decent or actually very good sound out of the Lcd-X or XC not saying that IEM would not be optimum which they ofc are....
Don't have the AK120, but own the AK100 MK2 which has that similar 3Ohm impedance. Using the Alpha Dogs is definitely lacking in power and sound is very, "soft" throughout. But it works very well with most of my other headphones (i.e. not Alpha Dogs! :p) In fact, I was surprise with the synergy with my Perfect Sound Didos which are very sensitive/low impedance full-size headphones!
