Dell Latitude 5350 laptop and 2-in-1 docks: power and ExpressCharge

Both Latitude 5350 forms provide two Thunderbolt 4 ports and require 60 W for optimal performance. Battery size changes the ExpressCharge requirement: 65 W for 42 Wh, but 100 W for 54 Wh.

Which dock options should you consider?

Dell lists every current WD25 family and the reviewed WD22/WD19/UD22/HD22Q families for Latitude 5350. For a new desk, start with WD25 for a normal 60 W USB-C requirement or WD25Z/WD25TB4 when you want more power headroom. Use WD25TB5 only as a listed dock that falls back to this Thunderbolt 4 host's capability. Older docks remain valid reuse choices, but a 54 Wh battery needs 100 W for ExpressCharge; the 90–96 W choices can operate the laptop yet do not meet that exact fast-charge threshold.

WD25, WD25Z / SD25 or WD25TB4 / SD25TB4

Dell's March 2026 matrix lists these current families for Latitude 5350, and all exceed the model's 60 W optimal-performance requirement on paper.

Check first: For 54 Wh ExpressCharge, choose a path delivering 100 W or more. For 42 Wh ExpressCharge, Dell requires 65 W.

WD25TB5 / SD25TB5 or WD22TB4

Dell also lists these Thunderbolt-family options for the exact laptop/2-in-1 row.

Check first: The Latitude 5350 is a Thunderbolt 4 host; a TB5 dock does not upgrade the host link. Verify requested display modes and the dock's supplied cable.

WD19 families, UD22 or HD22Q

Dell's model row keeps these older/universal docks as documented reuse choices.

Check first: Use WD19DC/DCS with one host cable. WD19S 130 W-supply, UD22 and HD22Q deliver under 100 W to the host, so they do not meet the 54 Wh ExpressCharge requirement.

Connect displays and power

Computer cable: Use the dock's specified USB-C/Thunderbolt host cable directly in either Latitude 5350 Thunderbolt 4 port. Dell documents DisplayPort Alt Mode, USB4 and Power Delivery on both.
Display cables: Connect monitors to documented dock HDMI or DisplayPort outputs with direct cables first. The laptop's HDMI 2.1 TMDS port is the clean direct path for isolating the monitor and cable.
Power: Normal optimal-performance power is 60 W. ExpressCharge requires 65 W with the 42 Wh battery or 100 W with the 54 Wh battery, and ExpressCharge must be enabled in BIOS.
Operating-system exception: Dell's setup documentation supports Ubuntu on the Latitude 5350 laptop, not the 2-in-1. Dock software features such as DisplayLink and enterprise controls still need verification for the installed operating system.

First recovery steps by symptom

Nothing on the dock works

Confirm the dock has its specified AC adapter and a powered status indicator.
Reconnect the manufacturer-specified host cable directly to one Latitude 5350 Thunderbolt 4 port, without an extension or hub.
Move the same cable to the second Thunderbolt 4 port and test one known-good USB accessory before changing displays.

USB works, but a display does not

Reduce to one monitor on one direct dock HDMI or DisplayPort output and select the matching input.
Test the monitor from the laptop's direct HDMI 2.1 TMDS port with a known-good cable.
If direct video works, update the exact dock firmware and graphics driver, then add another monitor only after the first dock path works.

Charging works, but ExpressCharge does not

Identify whether the laptop has the 42 Wh or 54 Wh battery.
Confirm at least 65 W host delivery for 42 Wh or 100 W for 54 Wh, then check that ExpressCharge is enabled in BIOS.
If the dock cannot meet that threshold, use the matching Dell 65 W or 100 W USB-C adapter rather than treating normal charging as a fault.

Still unknown: Dell does not establish every combined monitor mode, high-refresh/HDR result, cable conversion or operating-system feature for each listed dock. The laptop versus 2-in-1 form, battery size, dock revision, firmware and display path remain part of the check.

Before choosing a dock

Match the entire device name, including processor, generation and chassis variant.
Record your screen models, inputs and intended resolutions and refresh rates.
Confirm those screens work together through the proposed dock outputs.
Check the supplied power adapter, laptop charging requirement and software permission.
