DIY Portable Power Box Solar Charge Upgrade

Recently I finished building my first portable power box in an “ammo can”, and have been charging phones and testing radios with it.

However… now it’s time to top the battery off, so I’m upgrading the box with a charge controller, and external port to plug in a solar panel.

Here’s the video tutorial I’m following to upgrade.

Parts Needed:

The solar charge controller used will only handle up to 7 amps of current, so make sure your solar panel does not exceed that output, or you’ll need a heavier duty controller instead.
