Our take
CB-CS17 may suit the listed iPad generations when HDMI, card access, wired audio, and a charging path are needed in a compact tablet attachment.
A user of a listed iPad generation who needs HDMI, one-card import, headphone output, and a USB-C charging path while accepting device-specific modes and case-fit checks..
Skip it for confirmed 4K/60Hz, fast simultaneous two-card transfers, microphone input, guaranteed two-port USB expansion, or a verified historical-ASIN offer.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- LENTION lists a tablet-specific HDMI, card, audio, and charging combination.
- Video modes are described separately for macOS and iPad use.
- The 3.5mm jack is explicitly described as output-only.
What to weigh up
- The manufacturer's port-count descriptions conflict between one and two USB 3.0 sockets.
- Card reading is limited to one card at a time at a stated USB 2.0 rate.
- Neither frozen ASIN is mapped to CB-CS17 or a current offer.

Full review: how the features affect your choice
What the features mean for you
Match the hub to the iPad-focused expansion it was designed for
LENTION's official page identifies CB-CS17 as a USB-C adapter for recent iPad Pro models and describes a specific combination of HDMI, USB, SD and MicroSD, USB-C charging, and 3.5mm audio. That feature set addresses the common iPad problem of having one host connector but needing a screen, card access, a wired accessory, and a charging path at the same time. The maker lists the 2018–2020 iPad Pro 11-inch and 12.9-inch models, plus the 2020 iPad Air. Check the exact tablet model and connector before ordering; a similar-looking hub for a MacBook may not have the same tablet-fit case or software behavior.
Set video expectations by device and activity
The manufacturer does not describe this as a universal 4K/60Hz dock. It lists up to 4K at 30Hz on macOS and up to 2K at 60Hz on iPad Pro, with the home screen and applications reaching 1080p at 60Hz. During video playback, the output can switch to match the content up to 4K/30Hz. This distinction matters if you want a desktop-like workspace, a smooth cursor on a monitor, or playback on a hotel display. Match the hub's stated modes to the display and use case rather than relying on the historical title's shorter 4K HDMI phrase. The source does not establish dual-screen output or a 4K/60Hz mode.
Treat the 3.5mm jack as headphone output
The 3.5mm port restores a wired listening connection for an iPad that lacks a headphone jack, and LENTION specifies 16-bit/48kHz digital audio. The same page limits the jack to audio output. It says there is no inline volume control, phone-call function, or audio input. This makes it a better documented fit for listening or sending sound to an auxiliary input than for a headset microphone, calls, or recording. If you need microphone capture or controls in the cable, verify a different adapter's full audio specification instead of assuming that every 3.5mm socket supports a four-pole headset.
Check USB behavior and the disputed socket count
LENTION's detailed CB-CS17 feature text says one USB 3.0 port and gives a maximum data rate of 5Gbps. It says that under iOS the port is for a keyboard only, while iPadOS allows a mouse, keyboard, or flash drive. The page's comparison area appears to show two USB 3.0 ports for the lead product column, so the published count conflicts. Do not plan around a second downstream data socket until the exact offer's product images or seller documentation settle the discrepancy. The operating-system note is also practical: an older iOS setup may not use that port like a general-purpose laptop hub. Confirm both the iPad software version and the intended peripheral.
Understand the card-reader limits, charging path, and case fit
The manufacturer says the card slots read one card at a time and notes USB 2.0 reader speed around 30MB/s. Its documentation further narrows supported card use to particular image-import behavior. That may be adequate for moving photos from one card, but it is not evidence of a fast general-purpose dual-card workflow. The comparison lists USB-C Power Delivery up to 100W; treat that as the adapter's advertised charging input, not a guarantee that the iPad receives the full figure. The page also describes a magnetic removable adapter case: it is designed around genuine Apple cases, while a third-party case may need to be removed. Check whether the rigid plug can seat fully in your case before buying.
Verify the exact CB-CS17 listing rather than using the old ASIN as proof
The row's feature combination matches LENTION's official CB-CS17 page closely, so the manufacturer model gives a useful way to find the right family. The frozen Amazon ASINs B07T4NKT3D and B07T3L6R4J could not be mapped directly to CB-CS17 or a current offer. The tagged search above is therefore preferable to presenting either historical code as a verified direct product link. Compare the offered hub's model text, port face, color, and included adapter case. LENTION describes a compact aluminum-bodied accessory, but this review does not infer durability or thermal performance from the material description. It is based on the published page, not physical testing or customer-review summaries.
