Made by PWR+ for use with certain Dell ultrabook computers.
Cigarette lighter jack input. This version of the DC adapter has the somewhat rare Dell 4.5mm barrel plug output. The 7.4mm plug is much more common, we also sell a power supply for that. Works with our Half-Pint and Villager systems or any 12V DC source.
Consider buying a spare since these don’t last forever and the price is right…
If you have a working 7.4mm Dell power supply and just need to adapt the tip to fit your computer, you can buy this dongle.
