ATX PC source as a cell phone charger

Hello .. I have an ATX source of 300w and I want to use it to charge cell phones. The reality is that I already tried it by charging a cell phone and normal charging, but my doubt is that on the board it says to have an output of + 5vaux 2A that I would believe What is the violet cable because it also says + 5v 25A but they are red that there are 5 outputs I think from what I was seeing. Those 25A would be divided into the 5 outputs? When I connect either a violet or a red do I have to connect with the black that would be the mass? And the other is I would have to worry if I leave the cell phone all night long or something can happen? I heard once that the chargers are intelligent and that they cut off the current once the battery is 100% charged, but it turns out that now an expert confirmed that the chargers are not intelligent but that the cell phones regulate that of cutting when it reaches 100% the battery .. I hope you can help me .. since thank you

Hello, what I can tell you is that the cell phones are charged with low amperage just to prevent the battery from burning or exploding. The pc source has no cut and will deliver with the violet + black cable (which would be the negative) 5 vol 2.5 amper.

By step, if you are going to use it for several cell phones, you can use it for Red 5+ and black - now, not all cell phones charge just for keeping the voltages, most of you have to join those of Tx r Rx (green and white in the cell cable). The sources have a low R that you can start it alone, but if I advise you not to leave them more than 5h, or start the source with them connected. And about how much the battery admits, the cell phone has an internal sensor that stops or reduces 95% when it is charged, I hope it helps you, regards
