What It Is and Who It Is For

The DELL LX-130W is a 130W AC adapter built for Dell XPS 15, Precision and Inspiron laptops that require a 4.5*3.0mm barrel connector. It supplies 19.5V at 6.67A for compatible models including the XPS 15 9530 and Precision 5540.

Practical Limits of the Barrel Interface

The 4.5*3.0mm plug fits only devices designed for that specific barrel size and 19.5V input. It cannot charge systems that use USB-C Power Delivery or a different barrel diameter, and it does not support data transfer.

Deciding Specification: Output Power

This unit delivers up to 130W from a 100-240V AC source. If your laptop’s original charger is rated at 130W with a 4.5*3.0mm tip, this adapter matches that requirement; lower-wattage models will not draw the full capacity.

Questions about this item

Should I choose the 85 W or 130 W output rating for my Dell XPS 15 9570?

The adapter delivers 130 W at 19.5 V and 6.67 A, matching the original charger for XPS 15 9570; the 85 W figure appears in specifications but the unit is built for 130 W loads.

Will 19.5 V and 6.67 A charge my Precision 5540 at full speed under load?

Yes, the 19.5 V 6.67 A output supplies the full 130 W the Precision 5540 expects, so the battery charges while you work without throttling.

Does the 4.5 mm by 3.0 mm barrel connector fit the Inspiron 7790 charging port?

The 4.5 mm × 3.0 mm tip matches the Inspiron 7790 DC jack; it is not a USB interface, so plug it directly into the laptop's barrel port.
