The Targus 75 Watt charger comes with three interchangeable connector tips, but only two of these are compatible with laptops. The Targus Tip 18 is used to power certain Motorola mobile phone models. The laptop tips function with different laptop models that require that require a 75-watt or 16 volt-charger. If used with compatible laptops equipped with the appropriate power jack, the charger can automatically adjust for the computer’s needed amperes.

Defined

Laptops come with a variety of different voltage requirements. Many older Pentium III and IV models, like the Lenovo T40, T60, Panasonic, Toshiba, Sony and Fujitsu use this 16-volt requirement, so the Targus charger will work with them, providing one of the two laptop connector tips fits the power jack port on the computer.

Tip #21

This tip is narrow and elongated, and it works with several Gateway, IBM and WinBook laptops. If you are unfamiliar with Laptop AC Adapter for TOSHIBA PA3290E-3AC3 tip connectors, use the Targus Tip configurator to see if it is compatible with the laptop. Enter the laptop make and model in the appropriate boxes and Targus will inform you whether it is compatible with that model.

Tip #19

This power jack tip is used to power certain Fujitsu, Panasonic and Sony VAIO VGN-FS740/W AC adapter. One way to determine if this tip fits your laptop jack is to physically look at the power jack to see if there is an interior female connector where the tip middle pin fits. If you visit the Tip Configuration page on the Targus website and enter the computer manufacturer and model, Targus will inform you as to its compatibility.

Connection

To ensure that the Targus 75W power adapter works correctly with the laptop, the tip must connect firmly to the power adapter pins. If it is loose, the tip does not make a good connection with the power source. To connect it correctly the pins on the tip must align with the female pin connectors on the Acer PA-1650-02 AC  adapter and must insert firmly. Ensure that the green LED light on the Targus power box centered in the middle of the cord is lit. An unlit LED light indicates a lack of power and a failed Targus charger.
