Sadly the thing refuses to boot up now. Leave it for slow charge and hopefully tomorrow it will work. Else back to the shop for refund sigh.

Try holding the power button for 20 seconds.

Tried multiple times. It’s still stuck with totally black screen . The device is still taking in 5w of power but it’s totally black screen.

Sometimes a slow charge off a pc/laptop can help with random usb capable electronics. No idea if that will be relevant in this case. Luckily you are still near the store you got it at.

I'm going to guess it wasn't used much, so little so that the battery report system hasn't ever got to be calibrated. Similar to a new cellphone when you first get it.

I would also update the firmware next time it turns on, incase there was ever an update for this that passed some time ago (if it ever manages to turn on).

Try plugging it into a computer to charge it. Then while plugged in, try to power it on.
