Our take
Choose JCD401 for a capable USB4 or Thunderbolt host that needs several display connector choices plus two 10Gbps data ports. Its manufacturer page documents a clear port map and up to 85W PD pass-through. Check the exact computer before planning two displays: certain M1/M2 Macs support one external screen, and some dual-4K configurations may need 4K/30Hz.
A USB4 or Thunderbolt laptop owner who needs flexible display connections, two fast data ports, and PD pass-through, after checking the computer's display limits..
It is not a fit for a USB-A computer, a host without Thunderbolt 3/4 or USB4 when full features are required, a buyer needing Ethernet or card readers, or a two-display Mac setup that exceeds the computer's own output limits.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The official page identifies JCD401 and documents HDMI, DisplayPort, and a multifunction USB-C display/data output.
- Two downstream data ports are specified at up to 10Gbps, one USB-C and one USB-A.
- The maker lists up to 85W PD pass-through and explicitly describes host-related dual-display limits.
What to weigh up
- Full function depends on a Thunderbolt 3/4 or USB4 host; a USB-C connector alone is insufficient.
- Some M1 and M2 Macs support one external display, and dual 4K may require lowering resolution to 4K/30Hz.
- The old Amazon ASIN is not verified as a JCD401 offer and the 85W figure is not a measured result.
The key details
| Model covered | JCD401 |

What the features mean for you
Is your computer fast enough for the hub's full feature set?
JCD401 uses a USB-C host plug, but j5create specifies an available port supporting Thunderbolt 3, Thunderbolt 4, or USB4 for system requirements. That distinction changes the recommendation: the connector's shape alone does not promise the hub's display combinations or listed data path. The manufacturer describes compatibility with older USB specifications, while its full dual-display and USB4 behavior depends on the host. Check the computer's exact port documentation and graphics limits before purchase. This hub best suits an owner who understands the host requirements and wants to connect several display types from a compact adapter.
Which display combinations are documented?
The official page lists HDMI, DisplayPort, and a multifunction USB-C display output and describes up to two 4K monitors in combinations that pair two outputs. It also identifies exceptions: some M1 and M2 Macs support only one external display, and the manufacturer advises a maximum of 4K/30Hz if a dual-4K setup does not display correctly. The listed 4K/60Hz maximum should therefore not be read as a promise that every two-screen arrangement runs at that mode. Match the monitor combination to the computer's capabilities, and treat the published limits as specifications rather than a test on your hardware.
How much charging power can pass to the host?
j5create advertises up to 85W PD pass-through to charge a laptop and power connected devices. This is a stated maximum, not a measured wattage that every computer receives with any charger or combination of loads. The source does not give a separate PD input ceiling, so the profile does not convert the 85W output claim into an input rating. Confirm the laptop's accepted charging profile and use a suitable adapter. The PD input is distinct from the multifunction downstream USB-C port, which carries data and display output; follow the maker's port labels when connecting power.
Are two high-speed data ports enough?
The maker specifies one USB-C and one Type-A SuperSpeed+ 10Gbps data port. The USB-C output also supports DisplayPort video, so it has more than one documented role. This is a modest peripheral count rather than a large desktop bank; a user with several drives, an audio interface, or permanent accessories may need another hub. j5create also advises attaching a USB-C power adapter when using high-powered USB devices and no more than one bus-powered portable hard drive at a time. The speed figures are interface claims and do not guarantee independent full-rate throughput for every attached device.
What does the small attached cable mean at a desk?
The official page lists a 200mm attached cable and an aluminum enclosure. A short fixed lead keeps a separate host cable out of the bag but can limit placement if the laptop and display connections sit far apart. The adapter is better suited to a portable kit or a laptop placed near the cable cluster than to a tower under a desk. Measure the intended reach and ensure the USB4 host port remains accessible. The compact form does not add Ethernet, audio, or card reading; the product is strongest when display flexibility and two data ports are the actual priorities.
How should you find the exact Amazon offer?
The manufacturer page verifies model JCD401 and its published layout, but the historical Amazon ASIN B0BGSZJD9L has not been mapped to this current exact model. The affiliate destination searches by j5create and JCD401 rather than asserting a direct ASIN relationship. Compare the selected seller's model code and output map, especially if two displays or charging are central to the purchase. This review is based on manufacturer specifications; it includes no personal connection test, buyer-review summary, current price, stock, or sales claim.
What else to compare
Before you buy
Will JCD401 run two screens on every Mac?
No. j5create says some M1 and M2 Macs support only one external display.
Does the 85W figure mean every laptop receives 85W?
No. It is the manufacturer's maximum pass-through claim, not a universal measured result.
What host does the manufacturer specify?
An available USB-C port supporting Thunderbolt 3, Thunderbolt 4, or USB4 for full features.
Does JCD401 include Ethernet or card readers?
Those functions are not in the official page's listed port map.
Is B0BGSZJD9L confirmed as the exact model?
No. The tagged JCD401 search is used until an exact offer is verified.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.
