Lenovo USB-C 7-in-1 Hub: problems, parts and running costs

Checked: 2026-11-01

Summary

Owners report complete unit failures after less than two months, HDMI display dropouts, and power pass-through issues. Annual running cost is negligible at under $9 for electricity. It’s only a good buy under $25 used or if you need the specific Lenovo part number for compatibility.

Common problems and fixes

Complete unit failure — owners report units failing after under two months, with replacements arriving dead (no Power Delivery, HDMI or USB function). No confirmed root cause or published failure rate. [1][5]
HDMI display dropouts — display connection repeatedly drops over the hub while direct HDMI on the same laptop remains stable. Suggests possible hub/DP Alt Mode/video route problem. [5]
Power pass-through issues — peripherals work but power pass-through doesn’t; some users report tablet charging unsuccessful even though hub works with laptop. Can reflect PD negotiation/host incompatibility as well as device faults. [5]
External display limitations — inserting the hub disables laptop’s native HDMI output, leaving only one external monitor. This is a host GPU/display routing limitation, not a hub failure. [5]
Fixed captive cable — the 140mm USB-C cable is integral to the unit, so damage at its plug requires replacing the whole adapter. No separate replacement cable available from Lenovo. [1][2]

Parts and consumables

Whole hub service part (01FJ377) — $79.95 at Notebookparts, $147.95 at dedicated parts retailer for complete hub replacement. No factory-recommended replacement interval. [2][13][17]
HDMI cable (not included) — ordinary HDMI cable from hub to display. No proprietary Lenovo cable requirement. Replace only if faulty; for 4K30 use cable/display known to negotiate HDMI 1.4-quality mode reliably. [1][3]

Yearly running cost

Electricity is negligible. The 15W maximum consumption (5V × 3A) is not a measured steady-state draw. Assuming extreme constant 15W for 8h/day = 43.8kWh/year = $8.76/year at assumed $0.20/kWh. Actual draw is usage-dependent and normally well below maximum. Does not include laptop’s passed-through charging power or external monitor power. [1]

When it is a good buy

US listings for exact 4X90V55523 showed TeciSoft at $67.73, Office Depot at $75.99 (out of stock), and Notebookparts at $79.95 in November 2026. Regional GX90T77924 was $79.99 at CDW and $84.99 at Office Depot (backordered) in November 2026.

At over $35 new, this hub is hard to justify. The Plugable USBC-7IN1 costs $34.95 direct from manufacturer and gives 4K60 on revised edition, 100W input with up to 92W to host, three 5Gbps USB-A ports and two-year warranty. Belkin 7-in-1 runs $44.99–$49.99 with two-year warranty. For wired networking, the Plugable USBC-7IN1E adds Gigabit Ethernet at $39.95 but only two USB-A ports.

Used at $25 or less, the deal works only if every port and power path are tested and return risk is low.
