Camera has a DC - 5.0V port?

What is it for? My camera isn't marketed as chargeable, only battery powered. It's a Nikon Coolpix L820. It didn't come with a charger, only a USB cord and HDMI cord.
What is the DC - 5.0V port for? Google shows it's a charging port, but I don't think my camera is actually chargeable.
It would be nice if it is chargeable, four batteries go dead pretty quick with just minimal usage.

Sorry for repetitive details, lol.
Thanks.

How to get money fairly quickly at 13?

Hiya! Okay so, I want a good camera because the one I have now is really awful. I want to take good pictures and make a scrapbook about this summer but I don't wanna horrible pictures. So I want to buy a waterproof camera to take pictures at the beach and pool as well as other summer stuff. I'm deciding between two:

Or a refurbished one of these:

Pictures from my camera were not saved properly and will not erase and freeze my camera?

I have a nikon coolpix s4000. A few pictures on my memory card were not saved properly somehow and are just blank screens and it says files contain no image, but when I try deleting them it freezes my camera and will not erase them. I can't upload any of the pictures I have taken after I took the pictures that contain no image and I would really not like to lose those images but when I try uploading them to my computer it won't upload any of them because it says there's an error with images. I know there is nothing wrong with my camera because it still takes pictures and works fine. I just can't erase the pictures that are freezing my camera and say files contain no images. Please help?

Thoughts on Nikon Coolpix L110?

So I'm thinking of getting the Nikon Coolpix L110 within the next few weeks, and I was wondering if anyone would recommend this camera? What are some pros and cons?
I'm looking for extremely good photo quality, so I don't really care about the video on it.
Is there any other cameras anyone would recommend within the same price range as the Nikon Coolpix L110 that takes better quality pictures?
Thank you! :)
