Thank you for viewing. I have confirmed that it charges and plays music from an SD memory card. Playback and sound output from the speaker are OK. Charging can be done with a micro USB cable connected to a smartphone charger. It has AUX and MIC terminals, as well as a guitar input terminal, and it seems that recording is also possible. I have not confirmed the recording function as I do not know how to operate it. You can enjoy powerful sound despite its compact size. I don't play musical instruments, but I used it for background music. The items for sale are the main unit and a mini-plug conversion plug. Charging cables, chargers, SD memory cards, etc. are not included. This is a used item and will be sold as is. Thank you for your consideration.
