I found a "HiPOWER DC-DC Power Adapter" at a thrift store. I intend to use it to charge my laptop while in my car.
It has a range of voltages on the back with a dot under 19v. But when I tested it with a multimeter, it showed 19.92v. My laptop is rated for 19v, and its original charger tests at 19.45v. Will that <0.5v difference potentially damage my laptop?
