The Anker 240W USB-C cable is the best all-around Thunderbolt 4 pick here for a gaming laptop: it is a short 3.3 foot cable rated for 40Gbps data, 240W charging and 8K display output, which covers docks, external SSDs, eGPU enclosures and high-refresh monitors. Thunderbolt 4 is a cable and port standard that guarantees 40Gbps data, PCIe tunneling and support for high-resolution displays over a single USB-C connector. If you want extra bandwidth for the future, the UGREEN 80Gbps model is the stronger long-term buy. Two of the six listings are display-only DisplayPort cables, so read the details before you buy.
Top 3 picks at a glance
Quick List
- Anker 240W USB-C Cable – best for an everyday, short Thunderbolt 4 and USB4 connection to docks and drives
- UGREEN 240W 80Gbps Cable – best for buyers who want headroom beyond 40Gbps

Which One Is Right for You?
| If you… | Choose |
|---|---|
| Need one dependable cable for a dock, external SSD or charger within arm’s reach | Anker 240W USB-C Cable |
| Want the highest bandwidth rating and expect to upgrade to newer ports | UGREEN 240W 80Gbps Cable |
| Need two cables, one for home and one for the bag | Maxonar 2-Pack USB4 Cable |
| Have a dock or monitor that sits more than a meter from the laptop | ZIKNYDO 2m Cable |
| Want a 4K high-refresh monitor that only has DisplayPort and plan to charge separately | Silkland USB-C to DisplayPort 1.4 |
| Need a six foot video-only link to a DisplayPort monitor from a USB-C port | Cable Matters USB-C to DisplayPort 1.4 |
Before you shop, find out whether your laptop’s USB-C port actually supports Thunderbolt 4 or USB4, which is usually marked by a lightning bolt icon or listed in the specifications. Then match the cable length and the cable’s job: data and charging need a full-featured USB-C to USB-C cable, while a DisplayPort cable only carries video one way.
All 6 Picks in Detail
1. Anker 240W USB-C Cable – Best for Everyday Thunderbolt 4 Use
As an Amazon Associate we earn from qualifying purchases at no extra cost to you.
This 3.3 foot cable is the straightforward choice for connecting a gaming laptop to a Thunderbolt dock, an NVMe enclosure or a USB-C monitor. The listing says it is compatible with Thunderbolt 4 and 3 as well as USB4, with 40Gbps data, up to 240W charging and 8K display output. Anker’s separate Prime line is the one the manufacturer labels as Thunderbolt 4 certified, so read the listing carefully: this model is described as compatible rather than certified, which is still fine for most users but worth knowing.
- Length: 3.3 feet
- Data rate: 40Gbps, compatible with Thunderbolt 4 and 3 and USB4, per the listing
- Charging: up to 240W, which needs a charger and device that support USB Power Delivery 3.1
- Video: 8K display support per the listing
- Connectors: USB-C on both ends
Pros
- Short length keeps the 40Gbps signal reliable
- High charging rating leaves headroom for demanding laptops
Cons
- Described as compatible, not necessarily certified
- Rigid ends can be bulky on tight ports
Compared with the Maxonar, it is a single-cable purchase from a better-known accessory brand, whereas the Maxonar gives you two.
Who should buy it: players who want a reliable desk cable for a dock, a monitor or an external drive. Who can skip it: buyers who need more than 40Gbps or a longer reach.
Practical tip: label the cable you use for a dock and keep it dedicated to that job. Many gaming desks end up with a drawer of similar-looking USB-C cables that carry very different speeds, and a single mislabeled charging-only cable is a common cause of an external drive crawling or a monitor refusing to wake.
2. Cable Matters USB-C to DisplayPort 1.4 – Best Video-Only Link (Runner-Up)
This is not a Thunderbolt 4 cable, so treat it as a runner-up. It converts a USB-C or Thunderbolt port into a DisplayPort connection, sending video one way from the laptop to a monitor. The listing says it is unidirectional and warns it is not for portable USB-C monitors, which need a full USB-C cable. It lists 8K at 60Hz and 4K at 240Hz and a six foot length. It carries video only: no data transfer, no charging, and no connection to a dock.
- Length: 6 feet
- Video: DisplayPort 1.4, 8K at 60Hz and 4K at 240Hz per the listing
- Direction: unidirectional, laptop to display only
- Connectors: USB-C on one end, DisplayPort on the other
- Compatibility: the laptop port must support DisplayPort Alt Mode; confirm
Pros
- Simple, direct connection to a DisplayPort gaming monitor
- Long enough for most desk layouts
Cons
- Cannot charge the laptop or carry data
- Does not work with portable USB-C monitors
The Silkland cable has a nearly identical role with a slightly longer reach and an explicit mention of G-Sync, so choose between them on length and the features you need.
Who should buy it: players with a DisplayPort-only monitor and a spare charger. Who should skip it: anyone who wants one cable for display, data and power.
Setup tip: connect the monitor through its DisplayPort input, select that input in the on-screen menu, and enable the highest refresh rate in your graphics control panel, because monitors often default to a lower setting. If the picture flickers, try a different USB-C port on the laptop, since only some ports carry DisplayPort signals.
Think of it as a specialist: it solves one problem, a direct link from the laptop to a DisplayPort monitor, and it does that without the cost in complexity of a dock. If you later add a Thunderbolt dock, this cable becomes a handy spare for a second monitor.
3. Maxonar 2-Pack USB4 Cable – Best for Two Locations
The Maxonar set includes two 3.3 foot braided nylon cables, which is useful if you want one permanently at your desk and one in your backpack. The listing describes 40Gbps data transfer, 240W charging and 8K display support, and says it is intended for Thunderbolt 4-class and USB4 devices. A braided jacket is more resistant to tangling and wear than plain rubber, though cable quality is ultimately determined by internal wiring and the e-marker chip, which a listing rarely documents.
- Quantity: two cables
- Length: 3.3 feet each
- Data rate: 40Gbps
- Charging: up to 240W, per the listing
- Video: 8K support; braided nylon jacket
Pros
- Two cables cover a desk and a travel kit
- Braided jacket resists everyday wear
Cons
- Less brand documentation than the Anker
- Certification status is not stated in the listing name
It is the same tier as the Anker in rated specifications, with the pack format as its main advantage.
Who should buy it: people who want a spare cable on hand and do not want to buy twice. Who should skip it: anyone who values documented certification above a convenient two-pack.
A two-pack also helps with troubleshooting. If a dock or enclosure behaves unreliably, swapping in the second cable quickly shows whether the cable or the device is at fault, which is a common source of intermittent disconnects with high-speed links.
Check the packaging when it arrives: a USB4 or Thunderbolt-class cable should be clearly marked for 40Gbps, and a cable that charges your laptop but crawls with an external SSD is a sign the wrong cable is in use. Keep both cables of the pair for the same job type.
4. UGREEN 240W 80Gbps Cable – Best for Extra Bandwidth
UGREEN’s cable goes beyond Thunderbolt 4 on paper. The listing describes it as being for Thunderbolt 5 and USB4 Gen 4 at 80Gbps, with 240W charging, in a 3.3 foot length, and it also works with Thunderbolt 4 and 3. Thunderbolt 5 can deliver up to 80Gbps of bidirectional bandwidth, and more for video in a boosted mode, but your laptop and accessories must also support it. On a Thunderbolt 4 laptop it will simply run at 40Gbps, so you pay for headroom you may not use today. UGREEN also sells a 40Gbps version of this cable, so confirm the 80Gbps model before ordering.
- Length: 3.3 feet
- Data rate: up to 80Gbps, backward compatible with 40Gbps ports
- Charging: up to 240W
- Standards: Thunderbolt 5, USB4 Gen 4, backward compatible with Thunderbolt 4 and 3
- Video: confirm the supported resolutions on the listing
Pros
- Future-proof for newer laptops and docks
- Backward compatible with current Thunderbolt 4 ports
Cons
- Extra bandwidth is wasted on a Thunderbolt 4 laptop
- Variants with similar names can cause ordering mistakes
Compared with the Anker, it offers double the rated bandwidth, which only matters if your hardware can use it.
Who should buy it: owners of a new laptop with Thunderbolt 5, or buyers planning to upgrade soon. Who should skip it: anyone with a current Thunderbolt 4 laptop who just wants a simple dock cable.
One practical point: a high-bandwidth cable only helps when the accessory at the other end uses it. Today that mainly means newer Thunderbolt 5 docks, fast external storage and high-resolution multi-monitor setups, so check what your next purchase supports before paying for bandwidth that will sit idle.
If you only own Thunderbolt 4 hardware, a 40Gbps cable like the Anker meets every need, and the UGREEN becomes a choice about preparing for later equipment rather than solving a current problem.
5. ZIKNYDO 2m Cable – Best for Longer Reach
This listing is for a 6.6 foot, 2 meter cable with 40Gbps data, 240W charging and 8K/4K display support, marketed as compatible with Thunderbolt 4 and 3 and USB4. Two meters is the longest length at which a passive cable can maintain the full 40Gbps defined for Thunderbolt 4, so this cable is useful when your dock or monitor sits on the far side of a desk. Longer cables are more sensitive to quality, so confirm the 40Gbps rating on the product page and plug it in firmly at both ends.
- Length: 6.6 feet (2 meters)
- Data rate: 40Gbps, per the listing
- Charging: up to 240W
- Video: 8K and 4K display support
- Compatibility: Thunderbolt 4 and 3, USB4
Pros
- Extra reach for dock or monitor placement
- Full 40Gbps rating at 2 meters
Cons
- Longer cables are stiffer and heavier
- Brand documentation is limited
Next to the Anker, the main difference is double the length, so choose this one when distance is the deciding factor.
Who should buy it: setups where the dock or monitor is far from the laptop. Who should skip it: portable users who want the shortest, lightest cable.
Cable management tip: a 2 meter cable lets you tuck the dock behind the desk or under a monitor stand while the laptop sits on a cooling pad, but leave a gentle curve at each connector so the ports are not stressed by tight bends or the weight of a hanging cable.
As with any long cable, avoid pulling it taut or running it across a doorway, and keep it away from heavy chair wheels that can crush the jacket over time.
6. Silkland USB-C to DisplayPort 1.4 – Best Dedicated Monitor Cable (Runner-Up)
Like the Cable Matters cable, this is a display cable rather than a Thunderbolt 4 cable. It sends video from a USB-C or Thunderbolt port to a DisplayPort monitor at up to 8K at 60Hz or 4K at 240Hz, with 32.4Gbps of DisplayPort 1.4 bandwidth, HDCP and G-Sync compatibility noted in the listing. It is 6.6 feet long. It does not carry data or power, so it fits best as a second cable alongside a charger or a Thunderbolt connection.
- Length: 6.6 feet
- Video: DisplayPort 1.4, 8K at 60Hz and 4K at 240Hz
- Bandwidth: 32.4Gbps
- Features: HDCP, G-Sync noted in the listing
- Direction: video from laptop to display; confirm on the listing
Pros
- Direct link for high-refresh DisplayPort monitors
- Slightly longer than the Cable Matters option
Cons
- No data and no charging
- Requires a USB-C port with DisplayPort Alt Mode
It overlaps almost completely with the Cable Matters, so pick whichever length and features suit your desk.
Who should buy it: players who connect a gaming laptop to a DisplayPort-only high-refresh monitor. Who should skip it: anyone who wants a single cable for everything.
Because the listing mentions HDCP and G-Sync, it is aimed at players using adaptive-sync monitors. Variable refresh over a USB-C connection still depends on the laptop’s graphics routing, the monitor and its settings, so treat these labels as compatibility notes and confirm the details with your laptop’s manual.
Remember that a display cable pairs with a separate charger, so your desk will need two connections to the laptop: this cable for video and a power adapter.

How We Chose These
This guide is based on desk research. We started with the cables in current catalog listings and compared each one’s stated length, data rate, charging rating and video capabilities against the standards they claim to follow and against manufacturer information where available. Because two of the six listings are DisplayPort conversion cables rather than USB-C data cables, we kept them in the list but labeled them plainly as runner-ups. Where a listing did not say whether a cable is formally certified, we flagged that and did not assume it. Compatibility always depends on your laptop’s port, so we encourage you to check that first.
What to Look For
Thunderbolt 4, USB4 and plain USB-C are not the same
Thunderbolt 4 guarantees 40Gbps data, support for two 4K displays or one 8K display, PCIe data tunneling for external GPUs and storage, and at least 100W of charging. USB4 at 40Gbps shares the same speed but makes several features optional, and a basic USB-C cable might only carry USB 2.0 speeds at 480Mbps. A cable listing that says “compatible with Thunderbolt 4” is making a weaker claim than one that has been certified. For eGPUs and demanding docks, look for a certified cable or a listing that clearly states 40Gbps.
Length matters more than most people expect
Passive cables hold full speed at short lengths. For Thunderbolt 4 the passive limit is 2 meters, and many 40Gbps cables are made at 0.8 meters or shorter for signal reliability. A longer cable that is not designed for 40Gbps may fall back to a lower speed, which will appear as a slow external SSD or a monitor that will not run at its top refresh rate. Rule of thumb: choose the shortest cable that reaches comfortably, and use a 2 meter cable only when you must.
Charging wattage and safety
USB Power Delivery 3.1 allows up to 240W, but only when the charger, cable and laptop all support that level. Many gaming laptops still charge from a dedicated barrel adapter, and many USB-C gaming laptops accept 100W to 140W. A cable rated for 240W will work safely at lower power, but a cable rated for less than your charger can overheat or throttle. Use cables with a proper e-marker chip, avoid damaged or frayed cables, and stop using any cable that becomes hot to the touch.
Display cables and what they can and cannot do
A USB-C to DisplayPort cable converts the laptop’s DisplayPort Alt Mode signal into a standard DisplayPort connection. It cannot carry data or power, and it generally does not work with portable USB-C monitors, which expect a full USB-C connection. A DisplayPort 1.4 link offers 32.4Gbps of raw bandwidth, enough for 4K at high refresh rates, often with Display Stream Compression for the highest settings. A worked example: to run a 4K 144Hz monitor from a Thunderbolt 4 laptop, you could use a Thunderbolt cable to a dock or a USB-C to DisplayPort cable straight to the monitor, then charge via the laptop’s own adapter.
Check your laptop’s ports first
Not every USB-C port is a Thunderbolt port. Many gaming laptops include a mix of USB-C ports with different capabilities, and only some support Thunderbolt 4, USB4 or DisplayPort output. Look for a lightning bolt icon beside the port, check the specifications page for your exact model, and verify what your dock or enclosure requires. Buying a premium cable will not enable a feature your port lacks.
Questions
Do I need a Thunderbolt 4 cable for my gaming laptop?
You need one if you use a Thunderbolt dock, an external GPU enclosure or a fast external SSD, because those depend on the full 40Gbps and PCIe tunneling. For simple charging or a basic USB-C monitor, a standard USB-C cable can be enough.
Is a USB4 cable the same as a Thunderbolt 4 cable?
They share the same 40Gbps speed, but Thunderbolt 4 makes more capabilities mandatory, including support for two 4K displays and PCIe tunneling. A USB4 cable may work with Thunderbolt devices, but certification gives stronger assurance.
Will an 80Gbps cable work with a 40Gbps laptop?
Yes, an 80Gbps cable is backward compatible and will run at the speed your laptop and accessory support. You gain no extra speed until both ends support the higher standard.
Can I charge my laptop with these cables?
The USB-C to USB-C cables are rated for up to 240W, but your charger and laptop must support the same power level. The two DisplayPort cables cannot charge a laptop at all.
Why does my monitor not work with the DisplayPort cable?
The laptop’s USB-C port must support DisplayPort Alt Mode, and the monitor must be set to the matching input. Some ports provide charging only, so confirm your port’s capabilities in the laptop specifications.
How long can a Thunderbolt 4 cable be?
Passive Thunderbolt 4 cables can be up to 2 meters while keeping 40Gbps. Longer lengths require active cables, which are built differently and are often rated for different features.
