Our take
LENTION CB-C34 provides a USB-C host, three USB 3.0 Type-A ports, HDMI, and SD/microSD readers. HDMI is listed to 4K/30Hz, while PD support remains unverified for this exact model.
A USB-C laptop user who needs three USB-A connections, one HDMI output, and SD/microSD access, but does not need confirmed laptop charging through the hub..
A buyer who needs 4K/60Hz, verified laptop charging, or a directly confirmed B08PYF4GH7 current Amazon offer.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manufacturer names the CB-C34 and lists three USB 3.0 data ports.
- HDMI and SD/microSD readers are included in the model-specific layout.
- The maker describes simultaneous SD and microSD access up to its UHS-I/104MB/s claim.
What to weigh up
- HDMI is listed up to 4K/30Hz rather than 4K/60Hz.
- PD support is not established for CB-C34; neighboring LENTION models are not evidence for it.
- The historical Amazon ASIN is not mapped to the current manufacturer page.

Full review: how the features affect your choice
What the features mean for you
Pick the CB-C34 for a modest USB-C expansion set
The official product page describes the CB-C34 as a USB-C adapter that adds three USB 3.0 Type-A ports, HDMI and SD/microSD card access. That layout can suit someone moving from a laptop with few built-in connections to a small group of wired accessories plus one display and memory cards. The three USB-A connections are the data-expansion part of the product; HDMI and the card slots serve different jobs. Buyers should count the actual connectors they plan to use instead of comparing “in-one” labels across products. The old Amazon ASIN is not confirmed as this exact model, so inspect the current product's name and port diagram before choosing a listing.
Match the HDMI ceiling to the monitor you plan to use
LENTION lists HDMI output up to 3840 by 2160 at 30Hz and says lower resolutions are supported at 60Hz. That makes it a possible fit for a 4K display used at a 30Hz mode, but it does not meet a stated 4K/60Hz requirement on the information provided. The USB-C host device must also support video output; a matching connector shape alone does not establish that capability. The manufacturer's page lists compatibility examples across laptops and tablets but does not provide a complete matrix for every exact computer. Check the host's display-output support and the monitor's preferred resolution and refresh rate before treating the adapter as a display solution.
Use the card readers when simultaneous access matters
The product page says the SD and microSD slots can read and write at the same time and advertises UHS-I/SD 3.0 speeds up to 104MB/s. This is useful detail for someone who expects to leave both card types inserted during a transfer workflow. It is still a published ceiling, not a measured result for a particular card or host. Card speed, file type and the computer's USB implementation can affect the practical transfer. If a specific camera card or workflow is important, verify the supported format and compare the card's own rating with the hub's stated reader limit. The simultaneous-reader claim comes from the manufacturer, not independent testing.
Treat the USB speed as shared interface capability
LENTION states that the three USB 3.0 ports support data transfer up to 5Gbps. The page does not establish that three attached devices each receive that rate at once. They connect through one USB-C host path, and connected devices, cable and host capability can change throughput. The layout is a practical way to attach several peripherals; it should not be read as three independent full-rate channels. The official feature bullets mention keyboards, mice, flash drives and hard disks, but they do not provide a power budget or per-port power specification. If a bus-powered drive has demanding power needs, confirm whether the hub and host can support it.
Separate CB-C34 evidence from neighboring LENTION products
The manufacturer's page includes a comparison table for several other LENTION hubs, including C31, C35, C36b and longer-cable variants. Some of those models list USB-C power pass-through, but those values cannot be assigned to the CB-C34 just because the page places the products together. The CB-C34 feature heading supports USB, HDMI and card-reader functions; the inspected text does not establish laptop charging through PD. Its historical Amazon page also could not be read. Search for CB-C34, compare the port arrangement and color shown, and confirm any required charging feature directly on the current offer. This profile uses published specifications only and makes no current-stock, price, sales or hands-on performance claim.
