Help powering led strip

Hi.

I'd like to light my shed by using an led strip. I was thinking of attaching it to usb so that I can use a power bank but I realised that the leds are rated for 12v and the power bank delivers 5v through USB. Is there a way I can get 12v through USB 2? If not, will using USB3 help? Assuming I have a power bank with a 12v usb output.

Otherwise what would be the best way to power the leds in a shed? I may eventually run power from the mains to the shed and was thinking of using USB wall sockets.

Please advise me.

Thanks
