diy pocket voltmeter for electronic device battery- cheap and truly portable

Description:
I recently put together a pocket voltmeter you can carry around in your pocket (an essential tool for testing your electronic devices or batteries). I added a clip to it and allow you to monitor voltage for solar panel, batteries, and electronic device electrical energy drainage. If you want one, you can purchase one soon for around $10 to $12 plus $2 shipping fee. I am still developing my webstore through EducateTube.com. Once I have completed the store I provide the link here. Check back soon. Thanks for watching!
