Kastar 65W AC Adapter for Toshiba

This Kastar power supply delivers 65W at 19V 3.42A for compatible Toshiba laptops. It replaces part numbers such as PA-1650-21, PA3396U-1ACA and SADP-65KB series. The package includes the adapter and a 3-prong extended power cord. Buyers who need a different output voltage or a USB-C connector cannot use this unit.

DC Connector and Input Limits

The barrel plug measures 2.5mm inner by 5.5mm outer diameter and must match the laptop socket exactly. AC input accepts 100-240V at 50/60Hz with a 1.6A draw, so it works on mains worldwide with the right cord. Over-voltage, over-current and short-circuit protections guard the output side. Laptops requiring a centre-pin or larger barrel connector will not fit.

65W Output Decides Compatibility

The single specification that determines fit is the 19V 3.42A 65W DC output; the laptop must list this exact rating. If the original adapter is rated higher or lower, this unit will not meet the power demand. Polarity and connector dimensions are fixed by the 2.5/5.5mm barrel. Always verify the laptop’s required wattage before ordering.
