Nice video, I learned a few things. Now I'll be able to calculate how much power my smartphone draws when I charge it from my portable solar panel :)

Thanks for the well-made video and helpful examples. You showed the calculations clearly and made it look easy. Which of course it is. Easy to know but harder to explain well, and you did a great job. Thanks.. now I will go and calculate how much money I can save by not leaving my PC switched on all day 😂

Why not just divide 288 (Wh) by 28 or 30 (watts) = ~10 hours
