Let me show you how to build a kit like this .
What Do We Need ?
![1.jpg](/proxy/?url=https://content.instructables.com/FZD/0T5Z/IVA51FIX/FZD0T5ZIVA51FIX.jpg&filename=1.jpg)
1:old power bank.
2:led head light.
3:heating wire 0.17mm thick and 50mm long that comes to 3.5 Ohm .
4:3d printed fire can .
5:Slide switch .
Testing If We Can Make Anything Purn !!

And as you can see it worked at the end , you have to make sure that your power bank can provide
enough power to make the wire heats up.
Almost Done

After 3d printing the box and the cover , extend the power bank level indicator PCB wires , glue the slide switch , soldering the VCC and Ground wires from the USB output pins connect the ground to LED ground and the VCC to the switch mddle pin to the LED via a variable resistor for current limiting it is time for testing :)
Does It Work ?
