Dell 0KXTTW 45W Ultrabook Charger

This 45 watt AC adapter is built for Dell ultrabooks including the XPS 14 models 1364 and 1591 and the Inspiron 14 I14Z-1500SLV. It delivers 19.5 volts at 2.31 amps through a barrel connector and ships with a North American power cord. World-wide input voltage of 100 to 240 volts at 50 or 60 hertz allows use abroad without a voltage converter.

Suits owners of the listed ultrabooks needing

Buyers whose laptops require a higher output than 45 watts or a different connector type should look at something else. The unit is not designed for devices that draw more current than 2.31 amps at 19.5 volts.

45 watt output at 19.5 volts

The single specification that decides fit is the 45 watt maximum output at 19.5 volts; if the original adapter matches those figures and uses the same barrel tip this unit will work.
