This looks very much like the Rommoss car charger. I have one for my laptop. This gets its source from 12V DC instead of AC, but the rest works the same. Usb port and automatic voltage sensing circuitry. You just need a specific cable for whatever you're charging. Plug in a standard usb cable to charge your phone, you get 5V. Plug in an adapter cable for your Dell laptop, get the desired 19V (or whatever your laptop needs). http://www.amazon.com/Universal-Portable-Charger-Charging-Latitude/dp/B008QV0AF0 http://www.amazon.com/Universal-Portable-Charger-Charging-La...
