Former Community Member
Former Community Member

I'm building a solar powered laptop system and I have a question regarding to elecricity. Solar panel will be source of power which can produce 100W 18-21V 6A of AC. My laptop needs 19,5V 3,33A 65W of DC. How can I connect this two devices and make laptop run on solar power? It would be great to not use any additional battery, because laptop does have its own one.



Thanks for help!

    Most laptops detect a suitable charger so although its very inefficient, you may have to generate a suitable ac supply as above answers and then use a compatible charger back down to DC
