130w 4.5mm AC Adapter Compatible with Dell XPS 15 7590 9570 9530 9550 9560 Precision 5540 5530 5520 5510 M3800 M2800 Round Tip AC Adapter

Works perfectly with my Dell Precision 5540. It is a robust 130kw, just like the Dell adapter. Excellent price.

Item works great and is compatible with my OptiPlex 7050. Doesn’t get warm or anything. Also doesn’t throw an “unidentifiable power adapter” error on boot, either, so my system doesn’t throttle.

I recently ran into an issue with my Dell OptiPlex 7050 Micro after making an incorrect BIOS setting. I enabled a “check and remind” feature that monitors the power supply, not realizing it would lock me out if an underpowered AC adapter was detected. With a Core i5 processor, my system required no more than 65 watts, so I was using a 65W adapter without issues until this setting was activated. Once enabled, the BIOS demanded a 130W AC adapter, displaying a warning message and initiating a shutdown within 30 seconds. No matter what I tried, I couldn’t access the BIOS to reverse the setting, leaving me stuck.The problem happened around 8:00 PM, that's also when I searched Amazon and found this 130W AC adapter. The listing promised next-day delivery, which was a relief given my urgent situation. True to its word, the adapter arrived the following day and completely saved the day. I plugged it in, and my OptiPlex 7050 Micro booted up without any issues, allowing me to access the BIOS and correct the setting.The adapter itself is impressive, especially for its $20 price point. It’s compatible with the 7050 Micro, featuring the required 4.5mm OD, 3mm ID barrel DC connector. The build quality feels solid, with a sturdy design that suggests it will last for years under normal use. I’m confident in its durability and plan to keep it as my primary adapter for the 7050 Micro, freeing up my old 65W adapter for another mini PC I have on hand.This adapter is a fantastic value for anyone needing a reliable 130W power supply with a 4.5mm barrel connector. At just $20, it’s a steal, especially considering its performance and compatibility. I highly recommend this product to anyone looking for an affordable, high-quality AC adapter for their Dell OptiPlex or other compatible devices. Don’t pass it up!

Spot on replacement for the factory power supply. No warnings from the laptop stating that it's not an "authentic Dell replacement".

Bought this charger for my Dell XPS 7590, and it works without any issues.My only gripe is that the led light on the side that plugs into the laptop is always on, even when there’s no laptop connected.

Funciona perfectamente

Lighter and much less bulky than the Dell factory original. Note that the power draw can spark when plugging in. I recommend plugging in the Edison end of the AC cable first, then plugging the other end of that cable into the power brick.

It seems to function, and provides power to my Precision 5540, but it will not charge the battery, even after a Bios update. You would probably be best served with the official charger, as Dell locks things on their machines down like this.
