First Solar Charge

The other day was nice and sunny so I put my cell phone on one of the solar chargers. The battery was so low the phone would not start up. After a few hours it was nearly charged! This is a 5 Watt panel that has a direct USB power out.

  • I’ve got this cool battery meter application for Android that is quite helpful. https://play.google.com/store/apps/details?id=com.manor.currentwidget

    Here’s a note from the author in case more information is needed than the app gives:

    Look at the battery driver folder : /sys/class/power_supply/battery (root isn’t required).
    It has text files with with all the values that the battery driver exports. You can use Astro file manager to view them (some file manager can’t open those files for some reason).
