I wanna charge a Dell Latitude E6500 laptop from the cigarette socket (12V), and have now tried two Vanson laptop adapters (SDR-100W and SDR-120W). Both deliver a weak beeping and does not charge the laptop battery.
According to the regular power adapter the Laptop need 19.5V and 4.62A. On the laptop battery it says 19.5V and 3.5A minimum and 4.62A max.
Vanson SDR-100W Vanson Auto Power Adaptor 100W with adaptors for laptops, phones, mp3 players | eBay delivers 4.5A at 18/19/20V (you can switch between 18,19 and 20V). The plug fits into the power socket on the laptop and have "positive tip polarity."
Vanson SDR-120W Batterieliminator for laptop, 120W - VANSON | Clas Ohlson delivers up to 6A and can switch between 18,19 and 20V.
I bougth both the Vansons on a local shop here in Norway called Claes Ohlson.
Why do none of these charge my laptop battery?
