How exact ( +/- volts/amps) do you need to be when charging a laptop? Answered
It seems that most laptops charge at around 19volts (+/- 2) at around 3 amps. Can you charge a laptop at slightly over or slightly under its' charging voltage/amperage? I'm trying to make a "universal" solar charger.
If not, why?
I'm trying to make a solar panel that will charge a laptop. What I need to know is if it's ok for a laptop to charge at an amperage slightly over what its' charging cord is rated for (the panel would be directly wired into the laptop, bypassing the charging cord)
