Purpose and compatibility

This 130-watt AC adapter delivers 19.5 volts at 6.7 amps through a 7.4 mm by 5.0 mm barrel connector. It replaces original Dell chargers for a wide range of Inspiron, XPS, Precision, Latitude and Vostro laptops that require the same tip size and output rating. The unit accepts 100-240 volt input at 50 or 60 hertz for worldwide use.

Thermals, noise and power

The brick draws up to 240 volts AC and converts it to 130 watts DC without a fan, so operation is silent. Normal warmth is expected during sustained load; the black plastic enclosure dissipates heat passively. No active cooling or audible components are present in the design.

Included accessories

The package supplies the adapter itself and a detachable AC mains cord. Both pieces are corded-electric with no battery inside. The connector tip matches the listed Dell part numbers, allowing direct replacement without extra cables or software.

Questions about this item

How do I install the 7.4mm barrel connector and what step is often missed?

Align the 5.0 mm inner pin with the laptop's DC jack, push straight in until it seats firmly, then plug the AC cord into the 100-240V wall outlet — the step users miss is confirming the 19.5V 6.7A label matches the laptop's requirement before powering on

What maintenance or replacement will the 130W adapter need later?

The detachable AC cord can be swapped if the IEC C5 end frays; the brick itself has no user-serviceable parts, so replacement means buying a new 130W 19.5V 6.7A unit when output drops or the 7.4mm tip wears loose

What limit appears first during sustained 130W load?

The 19.5V 6.7A DC output rating is the hard ceiling; if the laptop draws the full 130 watts continuously the adapter will hit its thermal protection before any other limit
