This is how I run my laptop directly off my DC battery power. I connect a 12 volt cord to a battery. For my solar system I have gel batteries but when I go up to my other cabin I bring a deep cell battery. Red clamp on positive/ black clamp on negative.
Then I plug my DC power adapter for my computer into the socket.
There is a different DC power adapter for every laptop.
If you don’t have a DC power adapter for your computer you can plug a little inverter into the socket and it will run your AC laptop off of DC. They have an annoying little fan that eventually stops working so I don’t like using them.
When the laptop is not clamped onto the battery, is the battery connected to the solar panel?
The battery is always connected to the solar panel.
nformation about Running my laptop directly from a battery can I make reference. Today I did a lot of work in front of the laptop, so this information is very useful. Thanks
