Why is my PSVita not charging through the USB port on my PC?

Question

I want to charge my Vita via my PC's USB port. When I connect it, it hooks up to the PC and I can transfer items back and forth, but it does not charge.

I looked around and saw a few posts saying that you have to enable it in the options, which I did but still it doesn't work.

My USB 2.0/3.0 ports work for charging since I also charge other things, such as my iPod, iPhone, etc.

Is anyone else having problems charging the Vita from a PC?

Answer

The Vita's battery is 2200 mAh, so charging it on a USB 2.0 port (max 500 mA) would take almost 4.5 hours if it was off, which isn't great. If it's on, its power consumption rate can get up to about the same as that charging rate, so you wouldn't be doing much except turning the battery into a bomb.

According to this the Vita's charger is rated at 1500 mA, and other chargers are 2000 mA. This is significantly more that the USB 2.0 maximum or USB 3.0 max (900 mA) (source). As Resorath says, that must just not be enough.
