I am new here so I would like to say hi to everyone. I just recently jut into electronics and I have a question on a project I am working on.
I am trying to power a 20W heating element off of a 3.7v 18650 lithium battery. I wanted to know if it is possible to design a boost converter that can take the 3.7v and boost it to 20W? I know in order to calculate watts it is voltage x amps= wattage. the element I am working with says 5v and 4-amps to make 20W. I have googled this and I keep confusing myself.
Summary: I want to know if I can design a boost converter that can has an input of 3.7 and can output 5v @ 4-amps, or any combination there/of to achieve 20W?
