Re: Targus Power Adapters - question

Although I could be wrong, I believe that the Targus adapters only have a voltage setting, and have no current limiting beyond the "ultimate" limit imposed by the supply itself.

Anyway, I posted a table of voltages for most of the available tips.

Sounds like you'll have to make your own. AFAICT it's a couple of
programming resistors in the plug that set the voltage and current
limit, so it's theoretically pretty simple to lash something up.


No help, but I'd be interested in such a list as well. Just ordered a Dell Inspiron 700m, and have several Taurgus adapters (2 AC, 1 DC) and they won't list any tips for their older model adapters - I get the same runaround.


No-one can or will make Dell laptop adapters except Dell (and the Dell
branded auto/air(?) adapter by Targus(?)), as the Dell connector is a
three-pin special, and there's a communication between the power
supply and the computer that has to be just righ in order for the
battery to charge.
