Our take
UGREEN 70336 is a focused USB-C-to-four-port data expander. Its extra USB-C connector has a narrow power-input job, so buyers should not count it as a second peripheral port or as laptop charging.
A USB-C host owner who needs four USB data connections and may supply separate 5V/2A power to the hub..
Skip it when you need HDMI, Ethernet, card reading, USB-C data expansion, or host PD charging.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- UGREEN identifies SKU 70336 and four USB 3.0 ports
- The maker states that the separate USB-C input only powers the hub
- OTG support and a broad device-compatibility list are published
What to weigh up
- The extra USB-C input does not transfer data or video
- The page does not list adapter inclusion or exact current Amazon identity
- Five gigabits per second is a listed interface ceiling, not a measured result

Full review: how the features affect your choice
What the features mean for you
Four USB data ports connect to a USB-C host
UGREEN identifies SKU 70336 as a four-port USB-C hub and says its built-in OTG function expands USB connections for compatible phones, tablets, and laptops. The page lists four USB 3.0 ports and up to 5Gbps. That is useful when a host has USB-C but only a small number of peripheral sockets. The source does not promise four simultaneous 5Gbps streams, and the exact USB-A versus USB-C shapes of the downstream data ports should be checked on the pictured revision rather than inferred from the host connector.
The added USB-C port is for the hub's power only
UGREEN describes the auxiliary USB-C connector as a 5V/2A input that powers the hub. It explicitly says that this port carries neither data nor video. It is therefore not a fifth data connection and does not establish USB-C PD charging for a laptop. The page does not confirm that a wall adapter is included, so a buyer should check the package contents if the extra power input is needed. Keep the role of this connector distinct from a USB-C PD pass-through port on a docking station.
OTG wording does not guarantee every host setup
The manufacturer lists OTG support and names a range of USB-C laptops, tablets, and phones. A matching connector alone does not show that every device can operate the same set of peripherals or provide enough power for an external drive. Check the host's USB-C data and OTG support, especially for phones or tablets, and verify whether your device needs an external supply. The product page gives no individual device test matrix, so treat its broad list as a compatibility scope to confirm.
Count data ports separately from display and charging functions
The product page describes four USB 3.0 peripheral ports and a power-only USB-C input. It does not list HDMI, Ethernet, or card slots. That makes 70336 a narrower choice than a full USB-C dock, but a straightforward one when the missing functions are already available elsewhere. Do not interpret the general phrase multiport adapter as evidence for video output or memory-card access; select a model whose documentation names the function you need.
Verify SKU and variant when searching for the current offer
UGREEN's official page identifies SKU 70336, but it does not connect that model to historical Amazon ASIN B0BZS2BKXB. The old page could not be verified, so this recommendation uses a tagged exact-model search rather than an unproven direct item link. Compare the number of data ports, the separate power-only input, and the SKU before buying. This assessment relies on the maker's product text and makes no claim about current Amazon availability or personal testing.
Use it when the limited port map is enough
A buyer with a USB-C host who needs several USB peripherals may find the four-port layout sufficient, particularly if separate hub power can help with the attached devices. It is not the choice for charging a laptop, connecting a monitor, wired networking, or card transfer. The meaningful trade-off is a small data hub with an optional power input versus a larger dock with more roles. Confirm what power supply is included and whether the computer supports OTG before deciding.
