witch button is power on / off

cut off the power. no button control

output is Stereo ??asking because , connect s mono speaker Only

it\'sok, I will Manage for this order, but I would like to have stereo

How long does it take exactly to listen the music after it is powered up?I'm asking because I want to use it as a reverse tone player in my car so time is important.

there's a few second delay as the system is booting up. I wouldn't recommend that for any emergency or warning device as is it intended to play music and not a warning device. There's better option when it comes to warning when a vehicle is backing up. ... see more see less

What current does it draw?

The current draw will depend on the volume. It will vary from a few miliamps to about 1 amp at full volume.

does it have volume keys?

if you hold the next & previous buttons you get volume adjustment.

Is the audio file automatically looped? or is it also possible to single play (press button, audio is played, and then silence until next push on button)

check the Key operation instructions

Do you have a 12v version Need to run of a car battery

There is no 12V version, even if it can support 12V, it cannot be used in cars. Because it is connected to the speaker, there is no audio source output to the car amplifier for direct use.

Please explain how this is lossless. MP3 by definition is a lossy compression format.

Perhaps it can provide lossless function in MP3 format.
