DVD into phone charger

Hi. Yesterday I opened an DVD just because. My idea was to put it on the wall just for designs, but i thought i should make it functionable. So i reconnected the cables and the USB back and i managed to make it work,my phone was charging.
But i need some answers from the specialist.

1. Is there any kind of problem if you use this as an phone charger through USB?
2. Is there a problem if you use the USB,which was originally made for IN, as an OUT?
3. Is more energy power consumed?
4. Does it makes the same power as an phone charger?

Please don't ask why i want to make this

Here are some pics.
Thank you.

Welcome to the forums.

I'm not asking why you're doing this, I can't figure out what your end goal is.

There's no reason it will not work, but the USB port on the DVD player is probably not a high power port. This means the phone will charge slowly. It probably uses more energy compared to a phone charger because the power supply is also powering the other components in the DVD player.

@stickshift - My end goal was or is to make this DVD into something functional, because i want to put it on my wall. But i guess that's how it will end up.

@ibpooks - Even though there's nothing else connected to the main board? Just the usb.

Many modern electronics are always on. The "power" button just turns on and off the display. This is required so the device can listen for incoming signals from the remote control or the control channel of the HDMI. It's not enough to break the bank, but it will use more power than a stand alone charger.

Ok. Thank you for your explanations. I guess this was not a very good idea.
Thank's for your time. Cheers.
