Dell WD19S
This is the dock Dell makes specifically for its own laptops, and the integration shows. The proprietary dock port on the WD19S charges, syncs BIOS firmware, and handles up to three displays without breaking a sweat. I get a clean 130W of power to my Inspiron 15, which means I can run heavy workloads while the battery still trickles up. Driver support inside Dell Command Update is the cleanest experience of any dock I have used.
I have run my Dell Inspiron 15 through six different docks over the past two years. These are the five that actually played nicely with it.
I bought my Dell Inspiron 15 to use as a portable workhorse, but I needed it to behave like a desktop the minute I sat down at my desk. Two monitors, wired Ethernet, a webcam, a mechanical keyboard, and charging all from a single cable. After cycling through six docks over the past two years, here are the five that actually delivered on the Inspiron 15 without random disconnects, flickering monitors, or charging hiccups.

Dell WD19S
This is the dock Dell makes specifically for its own laptops, and the integration shows. The proprietary dock port on the WD19S charges, syncs BIOS firmware, and handles up to three displays without breaking a sweat. I get a clean 130W of power to my Inspiron 15, which means I can run heavy workloads while the battery still trickles up. Driver support inside Dell Command Update is the cleanest experience of any dock I have used.
CalDigit TS4
If your Inspiron 15 has Thunderbolt 4, the CalDigit TS4 is the dock I would buy. Eighteen ports, 98W of power delivery, dual 6K monitor support, and the build is solid aluminum that does not slide around. I love that the front has both USB-C and SD card slots, so I am not reaching behind the dock every time I plug in a camera card. It is pricey, but it is the last dock you will ever need.
Anker 568 USB-C Dock
For Inspiron 15 trims that are USB-C only, the Anker 568 is my value pick. It delivers 100W to the laptop, drives two 4K monitors at 60Hz, and the included 10Gbps USB-C front port is fast enough for an external NVMe drive. I have used this one on travel days when I plug into hotel TVs, and it has never failed me. The bundled cable is short, so plan accordingly.
Plugable UD-6950PDH
The Plugable is a no-frills workhorse with dual HDMI and DisplayPort outputs at 4K60. I keep one of these at my parents' house for when I visit and want a real desk setup. It works fine on the Inspiron 15 over USB-C, charges at 100W, and the driver installation is dead simple. Build quality feels plasticky compared to the CalDigit, but for the price, I cannot complain.
Kensington SD5750T
Kensington has been making docks forever, and the SD5750T is its current Thunderbolt 4 champion. It is a horizontal dock that fits neatly under a monitor stand, which I love for clutter-free desks. Performance is on par with CalDigit, but the port layout is more conservative. The Kensington DockWorks app is genuinely useful for managing power and security settings, particularly if you are in an office IT environment.
Common questions
Only the higher-end Inspiron 15 models with a Thunderbolt 4 port do. Most Inspiron 15 trims use USB-C with DisplayPort Alt Mode, which works with USB-C docks but caps bandwidth lower than Thunderbolt.
Yes, as long as the dock provides at least 65W of power delivery to the laptop. I prefer 90W or higher to keep things future-proof and avoid throttling under load.
