Unfortunately, it has gone up in smoke because of the reverse polarity.
#ALTERNATIVE POWER SUPPLY FOR MACBOOK PRO PLUS#
And I would not have confused Plus and Minus. The notebook power supply I would have today if I had not tried it without the 12V plug to connect directly to my motorhome board network. Only which is the best 12V charger for, eg, Samsung or Acer laptops? I bought a Hama car notebook power supply for my Lenovo laptop seven years ago, back then in Media Markt. The laptop charger for the car is plugged into the cigarette lighter and then provides your notebook with power, as at home too. You can quickly load your notebook with 12V. If you want to charge your computer in the car, you need a notebook car charger, or better a first car notebook power supply. That’s why it’s better if you want to charge your laptop in the car, not to go over a 230V inverter, but rather load the Notebook directly to the 12V battery.

The higher the difference, the more losses there are – in simple terms. So why bitteschön from 12V DC first make 230V AC and then again 19V DC? Every voltage change is associated with losses. The laptop usually requires 18 volts – the car battery (or Best AGM Battery in the camper) has 12V voltage. Why not charge the notebook with the inverter
