90W Original Lavolta Laptop In-Car Charger 12V DC &hellip by Lavolta
5.0 out of 5 stars It works!, 16 Aug 2013
I had a problem with a different similar product, which would allow me to use the laptop but would not charge the battery. Apparently this is a Dell feature which can distinguish authentic chargers. Whatever the reason, this one works fine and recharges the battery at the same time as powering the machine in use, and allowed me to get lots of extra hours work done while my wife was driving on our family holiday, then still have a fully charged machine at the campsite.
