Dell DA305 vs DA310 - USB-C Travel Hub Comparison 2026

Dell DA305 vs DA310: Two Similar Travel Hubs With One Real Split

The Dell DA305 and Dell DA310 are easy to confuse. They are both round Dell USB-C travel adapters, both use an integrated wraparound host cable, both provide Gigabit Ethernet, both pass through USB-C power, and both are built for the same basic job: turning one USB-C port into a small travel setup for one monitor, wired networking, and a few USB accessories.

The important thing is what they are not. Neither model is a full desktop dock. Neither replaces a Thunderbolt dock for a multi-monitor desk. Neither uses DisplayLink to bypass laptop display limits. Both rely on USB-C DisplayPort Alt Mode from the host, and both product YAML files say only one display works at a time.

The short verdict: The Dell DA310 wins by a small margin because it has a higher site score, the same 90W passthrough charging ceiling, the same one-display digital-video capability, and one extra video option: VGA. That extra port matters for classrooms, conference rooms, and older projectors. The Dell DA305 is still the cleaner pick if you know you will never need VGA and want the slightly newer, simpler 6-in-1 design.

Quick Specs Comparison

Design and Port Philosophy

These two adapters share the same basic Dell idea: a pocketable round hub with a cable that wraps into the body. That design is useful if you throw a hub into a laptop bag every day. It prevents a loose cable from disappearing, and it is tidier than carrying a tiny dongle plus a separate Ethernet adapter.

The DA305 is the more modern-looking port selection. Its YAML lists one USB-C port, two USB-A ports, HDMI, DisplayPort, USB-C display output, and RJ45 Ethernet. The product introduction describes it as the simpler 6-in-1 sibling to the DA310, and that framing is right. It keeps the ports most people still use in 2026 and drops the old projector connector.

The DA310 is the broader adapter. Its YAML lists the same USB-C and dual USB-A baseline, the same HDMI and DisplayPort coverage, the same Ethernet, and a VGA port. That gives it four display-capable outputs, but this is where buyers need to slow down: the DA310 still supports only one external display at a time. VGA increases compatibility with older screens. It does not turn the adapter into a multi-monitor dock.

Port winner: Dell DA310. The DA305 is cleaner, but the DA310 has every major DA305 port plus VGA. If you are deciding purely on port coverage from the YAML, the DA310 has the wider toolkit.

Display Support: Both Are One-Monitor Adapters

The display section is the easiest place to overbuy or misunderstand these hubs. Both have several video connectors, but both are one-monitor devices.

The DA305 YAML lists maxDisplays: 1. It can drive one 3840x2160 display at 60Hz through HDMI or DisplayPort when the laptop supports DisplayPort 1.3 or newer over USB-C DisplayPort Alt Mode. It also lists a 3840x2160 30Hz mode through the multifunction USB-C display output. The known incompatibilities explicitly say multiple external displays are not supported.

The DA310 YAML also lists maxDisplays: 1. Its strongest mode is a single 3840x2160 display at 60Hz through HDMI 2.0, DisplayPort, or USB-C MFDP when the host supports DisplayPort Alt Mode. Its second display configuration is a single 1920x1080 display at 30Hz through VGA. That VGA line is the practical reason to choose it. It helps when the room still has an old projector or older display input.

For a modern desk with two monitors, neither should be on your shortlist. Look at a larger USB-C, DisplayLink, USB4, or Thunderbolt dock instead. Our docking station buying guide explains the difference between travel adapters and real docking stations in more detail.

Display winner: Dell DA310, narrowly. Both handle one digital 4K display. The DA310 adds a VGA fallback. The DA305 has the same one-display limitation without that legacy option.

USB, Ethernet, and Everyday Peripherals

For basic peripherals, the DA305 and DA310 are nearly tied. Each product YAML lists two USB-A 3.2 ports and one USB-C 3.2 downstream port. Each lists 10 Gbps host connectivity. Each includes RJ45 Ethernet with 1 Gbps speed. Neither file lists an SD card reader or a 3.5mm audio jack.

That means the day-to-day setup is almost identical. You can connect a keyboard and mouse, plug into wired Ethernet, attach one display, and pass USB-C power through the adapter. You can also use the USB-C downstream port for data or video depending on how you set up the hub, but you should not assume it gives you extra display count. The one-display rule still applies.

The DA310 YAML includes one small extra detail on the USB side: the USB-A ports list 7.5W power delivery. The DA305 file does not list that value for its USB-A ports. I would not treat that as a buying-decision headline, because both are compact travel hubs and neither is positioned as a charging station. It is still a YAML-backed detail that slightly favors the DA310 if you regularly top up small accessories from USB-A.

Peripheral winner: tie with a small DA310 edge. Both cover the same practical USB and Ethernet jobs. The DA310 has a little more listed detail around USB-A accessory power, but the difference is minor compared with the VGA decision.

Charging: Same 90W Ceiling, Same Caveat

Charging is not where this matchup is decided. Both YAML files list USB-C power input, passthrough charging support, and a maximum host wattage of 90W.

The DA305 verdict and setup tips both warn that passthrough output depends on the charger connected to the adapter. Its cons mention that larger laptops may still need their original charger under load, especially when the source charger is small.

The DA310 has the same top-line 90W number, but its YAML gives a more detailed power caveat. The known incompatibilities say Dell’s power table shows the adapter reserves power for itself: a 90W source provides about 75W to the laptop, a 65W source provides about 50W, and a 45W source may not provide meaningful charging. Its setup tips recommend a 100W or 130W USB-C charger if you want the laptop to receive close to the maximum passthrough output.

The practical conclusion is simple. If your laptop needs close to 90W, bring a high-wattage USB-C charger. If your laptop is a smaller ultrabook, either adapter can reduce cable clutter at a hotel desk or meeting table. If your laptop is a high-power workstation, these adapters are travel conveniences, not power-dock replacements.

Charging winner: tie. The maximum is the same in the YAML: up to 90W passthrough charging. The DA310 file explains the power loss more explicitly, but it does not list a higher ceiling.

Compatibility and Driver Requirements

Neither adapter requires a DisplayLink driver. Both YAML files list driver.type: None and explain that video uses USB-C DisplayPort Alt Mode from the host. This is good for simplicity. There is no DisplayLink Manager install, no extra display driver, and no software layer for basic monitor output.

The catch is that your laptop USB-C port must support DisplayPort Alt Mode. A data-only USB-C port can still use USB and Ethernet, but it will not drive a display through these adapters. This is called out directly in both products’ known incompatibilities.

Windows is the strongest platform in both files. The DA305 YAML lists Windows 10 and Windows 11 support and describes Windows as the best supported platform. The DA310 YAML says Windows is the best supported platform too, especially with Dell business laptops that can use MAC address pass-through, PXE, Wake-on-LAN, and firmware management features.

macOS support is more cautious. The DA305 may work for USB, Ethernet, charging, and one display when the Mac supports the requested USB-C DisplayPort Alt Mode output. The DA310 YAML says it can work as a standards-based USB-C hub, but also notes mixed Apple Silicon feedback around Ethernet or detection issues. Neither product is a way to bypass base M-series Mac external-display limits, because neither uses DisplayLink.

Compatibility winner: Dell DA310 for Dell business laptop users, tie for everyone else. The DA310 YAML lists more enterprise-friendly features. For a generic Windows, Mac, Linux, or ChromeOS user, the same basic Alt Mode limitations apply to both.

Value: Newer and Cheaper Versus Broader and Higher-Scored

The DA305 has the lower MSRP at $109.99, while the DA310 is listed at $119.00. On paper, that gives the DA305 a small price advantage. It is also newer, with a 2022-08 release date compared with 2021-01 for the DA310.

That does not automatically make the DA305 the better value. The DA310 has the higher site score, 7.2 versus 7.0, and the extra VGA port. If the street prices are close, paying a little more for the DA310 can make sense because the older connector is exactly the kind of port you only miss when you are standing in front of a projector with no adapter.

The DA305 becomes the value pick when it is meaningfully cheaper or when you know your world is all HDMI, DisplayPort, and USB-C. Its own verdict says it keeps the best part of the DA310 design while dropping VGA. For many modern users, that is not a downgrade. It is just a cleaner port mix.

The DA310 value story depends on travel uncertainty. If you support conference rooms, client offices, classrooms, or shared meeting spaces, the extra port is useful insurance. If you only use your own monitor and Ethernet at a hotel or office desk, the DA305 is enough.

Value winner: conditional. DA305 if price is lower and VGA is irrelevant. DA310 if you want maximum travel compatibility from one Dell adapter.

Common Mistakes When Choosing Between Them

The first mistake is buying either adapter for dual monitors. The product YAML is clear: DA305 max display count is one, and DA310 max display count is one. Multiple video ports mean input flexibility, not simultaneous output.

The second mistake is assuming all USB-C laptops support video. These adapters need USB-C DisplayPort Alt Mode for monitor output. If the laptop port only supports data and charging, HDMI, DisplayPort, VGA, and USB-C display output will not work as expected.

The third mistake is expecting full 90W charging from any charger. Both adapters can pass up to 90W, but the connected charger matters. A small USB-C charger leaves less available wattage after the adapter reserves power for itself.

The fourth mistake is treating either model like a desktop dock. Neither includes audio, card readers, a fixed power supply, or multi-display support. If those matter, compare larger docks such as the Dell WD19S or Dell Universal Dock UD22 instead.

Verdict: Dell DA310 Wins, But the DA305 Is the Modern Minimalist Pick

The Dell DA310 is the better overall Dell travel hub in this matchup. It has the higher score in the site data, the same 90W passthrough charging ceiling, the same one-display 4K digital-video class, the same dual USB-A plus USB-C plus Ethernet foundation, and one extra port that the DA305 lacks: VGA. That gives it the broader real-world travel toolkit.

The Dell DA305 is not a bad choice. It is the one I would buy for a modern-only bag if it is cheaper. It is newer, slightly less expensive at MSRP, and removes the legacy port many people will never use. Its port mix still covers HDMI, DisplayPort, USB-C, Ethernet, and two USB-A accessories. For one monitor and wired networking, it does the job.

But comparison pages need a winner, and the YAML-backed winner is the DA310. The score is 7.2 instead of 7.0, and the port map is more complete. The DA305 wins only when your personal use case makes VGA unnecessary or when the street price gap is large enough to matter.

Choose the Dell DA305 if:

• You want the simpler modern Dell travel adapter
• You only use HDMI, DisplayPort, or USB-C display connections
• You do not need VGA for projectors or older displays
• You find it meaningfully cheaper than the DA310
• You want the newer 2022 release with a cleaner 6-in-1 layout

Choose the Dell DA310 if:

• You want the better all-around Dell travel hub
• You may need VGA in classrooms, conference rooms, or client offices
• You want the higher site score, 7.2 versus 7.0
• You use Dell business laptops and care about the enterprise-friendly features listed in the YAML
• You want the safest one-adapter travel kit from Dell
