In this video you will see a very simple way how to charge a 12 volts car or a motorcycle battery with 19 Volts laptop power adapter (laptop charger)
Difference between 19 and 12 voltages drops on a light bulb, I’ve used 12 volts 21 watt light bulb.
If you need higher current use two 21W bulbs in pararel, or you can use just one 55W light bulb.
