    Hello Mike,
    There are two yellow self-recover fuses inside the module. Your problem may be caused by the over-temperature protection.
    Could you open the metal shell and find out the four tin points which are marked by yellow frame in the attached picture. Then connect the four tin points by soldering as the attached picture below. By the way of this, the fuse will not work. If you still want the protection function, you can connect the four tin points by a 5-6A fuse.

    Hello Ziad,
    According to Conservation of energy, if the input is 3.6V 90mA, the module will not boost the values to 5V 2A. This module cannot amplify power.
    Hope this will be helpful to you.
