I saw a guy string together some 18650s in series and plug them into the power brick port on a laptop. Supposedly it works. I wonder though: If I have say, a 19V laptop and attach a 5s battery to its external power port, will it tolerate the variation of voltage in the battery? 21V - 15V?
Seems like some kind of regulator should need to be added to this thing if it were to function safely. What would such a device be called? When I search for Voltage regulators, I get car and motorcycle regulators, or buck converters. What I'm thinking of would be a device that would take a range of Voltage in, and send a steady 19V out.
I think it would be a fun project to build a sort of lap-desk with a cooling fan, USB hub, and a built-in 18650 external battery. With a cup holder.
