Can I power 12V LED strip with USB?
So, in short: no. If your LED strip needs 12V, you need to connect it to a 12V power supply, not a USB port. As @dandavis suggested in the comments, if you really want to power it from USB, you can get a 5V->12V step-up converter to get 12V from your USB supply.
Will a 9V battery power a 12V LED?
The answer is “Yes”. A 12V strip can run on a power supply a little lower than its required electrical voltage, like a 9V alkaline battery. This setup is even entirely safe to operate. LEDs are not rated for 12 volts, at least not directly.
Can you power a 12V LED strip with 5v?
You can install a 5v or 12v LED strip up to five meters from its power supply from one end—any more will cause a voltage drop. With 24v strips, these can be powered up to 10 metres from the power supply from one end.
