@Lucas2703 As long as the USB charger puts out enough juice to power your LEDs then you should be fine. You won’t be able to power the LED strip directly off of mains power. It will need to go through a transformer – essentially what the USB charger does – to step it down to the correct voltage for the LEDs. This is pretty common when you see lights installed under kitchen cabinets. Any electrical supply store should be able to help you out with everything you need.
