Watch this video to the end so you don't fail to understand..
Assalamualaikum see you again on my channel "BOCAH&NDESO" in this video I share a video on how to make a powerful step up dc to dc only with a 1.5 volt battery can turn on a 12v rgb led strip, and also a computer fan, if the input is given a voltage 3.7 volts should be given at the output a 12 volt zener diode, which serves to limit the voltage so that it is not more than 12 volts, which can cause the led strip to have a heart attack due to overvoltage :D please try it yourself, materials that need to be prepared ,, component list: 1) used lamp transformer machine / energy saving lamp lampu 2) NPN transistor d882/d313/tip 41c 3) 2x elko 220uf 16v 4) resistors 4 ohms and 100 ohms 5) the email wire is a bit big, don't know what size to take from the former transformer good luck, hope it's useful, thank you for liking, commenting and subscribing to my channel 🙏
