im looking for a DC DC boost converter for a car's battery ~10-15v to my laptops charger output (19v, 2.15A when charging). it doesn't make sense to use an inverter to: 12v DC -> 120V AC -> 19v.
im thinking:
Vin: 0-20v
Vout: 10-20V or so.
Aout: <=10A
Buy a universal laptop car power supply off the shelf. They are cheap, they work well, and they come with a guarantee. i.e., they're unlikely to blow up your laptop.
