When considering LEDs, it is essential to note that LEDs themselves are neither 12V nor 5V. Basic LEDs use a ballast resistor set to produce a specific current at a particular input voltage.
One viable option is to employ an LED string or strip designed for 5V instead of 12V, which can be used with virtually any USB power bank. Remember, some power banks might automatically shut off if the current draw is insufficient.

For those who need to use a 12V strip, there are two main alternatives. The first is utilizing newer power banks that include advanced features such as QC (Quick Charge) or USB PD (Power Delivery). These power banks can internally provide 12V with the appropriate protocols using a USB PD trigger board, which signals the power bank to supply 12V. The second alternative involves employing an external step-up or boost converter. Both solutions are compact and affordable.
Ensure you test your setup beforehand to confirm that the power bank remains active and does not enter a sleep mode due to insufficient power draw.
