I just got the AK100 MK2, late christmas gift to me, and I have one question. Is it OK to charge the device connected to a wall outlet via a smartphone (android or iphone) AC adapter?
So far I love this little device! I have about 1200 FLAC files loaded (mostly 16 bit and some MQS 24 Bit) and all I can say is, WOW! I previously owned the iBasso DX50, which was also a great DAP, but (for my taste) I had to use an external amp to tame down the harshness of the player. With the AK100 MK2 I don't see the need in using an external amp and ultimately reaching my goal of simplifying my rig (only DAP and headphones).
Yup. Totally fine. The wall chargers iriver sells are the same as typical usb wall chargers, which are no different from normal android chargers. I charge them via my phone charger as well. 5 volt 1A out.
