Toprid TM818 or YG1525CF manual/info help please

hello,

name of player is Toprid TM818 model (http://www.toprid.com is manufacter), or as a Toprid YG1525CF in store.

I would like to buy this player primary for voice recording, but would need more info on it.
Could please users of this player share the pdf manual and first hand info.

Does player have built in microphone?
Do I need external microphone for recording voice?
IS it easy to record or you need to go over 9 steps trough the menus?
How is it charged? With usb cable over computer only, has nonusb charger,...?

Thank you
