Our take
Consider UGREEN 30420 when a USB-A host, three downstream USB-A sockets, and separate stereo and microphone connections suit the desk. Its optional Micro-USB input is for hub power, not laptop charging. Sources conflict on USB generation because a page with a 30420 heading contains 30418 and USB 2.0 details, so do not choose it for a guaranteed transfer rate. B01HPMHOY0 remains a historical identity clue rather than a confirmed current Amazon offer.
A USB-A computer owner who needs a few USB connections and a separate headset audio path, and who can accept an unresolved USB generation..
It is not a fit for a USB-C-only host, a display or Ethernet dock, laptop PD charging, or a storage workflow that requires a confirmed USB generation and rate.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Three USB-A outputs and separate stereo and mono microphone jacks are listed.
- The 30420 model identity is supported by independent product records.
- An optional Micro-USB hub-power input is identified.
What to weigh up
- The USB generation and transfer rate conflict between 30420 and copied 30418 specifications.
- No HDMI, Ethernet, or card reader is documented.
- Neither a power-supply rating nor a laptop charging output is established.

Full review: how the features affect your choice
What the features mean for you
Confirm that your computer has the right upstream connector
Albadr lists one USB-A male host plug and three USB-A female outputs for model 30420. That makes it a candidate for a computer with an available USB-A port that needs more connections for ordinary peripherals. The inspected product records do not document HDMI, Ethernet, an SD reader, or a USB-C host plug, so this is not a laptop docking station for adding a monitor or wired network. A USB-C-only computer would need a separate compatible adapter, which is not part of this product profile. Check the connector and exact model label on the current offer before ordering.
The audio sockets are the distinctive feature
The product specification describes a stereo audio output and a mono microphone input through separate 3.5 mm jacks. That combination may help when a computer's built-in audio connection is unavailable or when someone wants a separate headset path at the desk. The listed ports do not establish support for every headset wiring standard, microphone type, or recording setup. Match the headset plug and microphone arrangement to the product's actual labels before relying on it for calls. This review uses the published port description; it does not claim a listening, recording, or compatibility test.
Treat the published USB speed as unresolved
Desertcart and Albadr describe 30420 as USB 3.0 and claim up to 5Gbps. A UGREEN Online page also has a 30420 heading and product code, but its specification block switches to PID 30418 and describes USB 2.0 at 480Mbps. The pages do not explain whether that block is a copying error or a changed revision. This profile therefore does not match the hub to a minimum transfer rate. Buyers who plan to use external storage should confirm the label and exact revision with the seller rather than relying on a general 5Gbps headline.
Optional external power does not mean a known charging output
Albadr lists a Micro-USB input for optional external power. That can be useful when several peripherals are attached, but the available documentation does not state its input rating, provide an included power adapter, or claim USB Power Delivery to a laptop. Do not confuse an auxiliary input with a charging output or assume it powers every attached device. If your peripherals have substantial power needs, ask for the current revision's supply requirements and use a separate supply only when its voltage and connector are specified. The review does not claim that a charger is included.
This is a small I/O combination, not a universal expansion dock
The documented package centers on three USB-A connections and stereo and microphone sockets. It omits the display, Ethernet, card-reader, and laptop-power features that appear on larger USB-C multiport docks. That focus can suit someone replacing an unavailable audio connection while adding a few USB devices. It is a poor fit for someone who needs a monitor, wired network, camera-card reader, or USB-C data connection. UGREEN's name and the two-in-one audio language do not change the physical host interface: the product record describes a USB-A connection. Search for the precise 30420 code and verify the current listing; the historical ASIN has not been mapped to an exact current offer.

Before you buy
What is the host connector?
Albadr identifies one USB-A host plug for this model; the product sources do not document a USB-C host connection.
How many USB-A outputs are listed?
The model-specific product description lists three downstream USB-A sockets, in addition to separate stereo and microphone audio jacks.
Is 5Gbps confirmed for every 30420 revision?
No. The 30420 USB 3.0 claims conflict with a copied 30418 block that describes USB 2.0 ports.
Does the Micro-USB input charge a laptop?
No laptop charging output is documented; the Micro-USB connector is an optional auxiliary input for powering the hub itself.
Is B01HPMHOY0 verified as the current Amazon offer?
No. B01HPMHOY0 remains a historical identity clue, and the tagged destination searches for model 30420 instead.
Where can I check the current price?
