  • Question about Solar Phone Charger

    I made 36 Cells in series and Im just about ready to connect it and see what happens.

    But Before I do I just need your opinion

    It says I can have 20 Volt.
    Im just wondering if I can have 20 Volt and 2 Amp
    or if its strictly telling me only 5V and 2 amp

    Im not sure the difference in this.

    To my understanding its 20 Volt and 2 Amp The little MPPT can handle

    Any thoughts or suggestions to clarify this?
