UGREEN 70336 Four-Port USB-C Hub review

Four familiar sockets, without a miniature dock

The UGREEN 70336 is for the fairly common situation in which the computer has USB-C but the accessories still have USB-A plugs. A keyboard, mouse receiver, USB stick and another small peripheral can stay together on one hub. Its purpose is straightforward data expansion. It does not try to combine a monitor, network cable, memory cards and laptop charging into the same enclosure.

That narrow purpose is useful when your display and charger already have satisfactory connections. You avoid buying a larger dock simply to obtain extra rectangular USB sockets. The maker identifies this silver version by SKU 70336, an important detail when comparing UGREEN products that otherwise have almost interchangeable titles.

Count the USB-A ports, not the auxiliary input

There are four USB-A downstream data ports. UGREEN advertises USB 3.0 operation at up to 5 Gbps, suitable as an interface specification for ordinary USB storage and accessories. That figure is not a measured copying result. The computer connection, attached devices and work being performed determine useful throughput, and the ports share the upstream link.

A mouse or keyboard rarely needs a fast interface; a storage drive is more likely to expose the shared bandwidth. If you regularly copy between several fast external drives, buying four sockets does not remove that bottleneck. If your main problem is simply having somewhere to connect everyday accessories, the four-port layout directly addresses it.

The second USB-C socket is not a laptop charger

The most important distinction is the auxiliary USB-C power input. UGREEN specifies 5 V / 2 A power delivery for the hub and explicitly excludes data and video through that socket. The familiar connector shape can make it look like the charging input on a more elaborate laptop dock. It is not documented as that function here.

Keep the laptop charger connected to the computer separately. Connecting power to the auxiliary socket does not create an HDMI output, another USB-C data connection or pass-through laptop charging. This also means the 70336 is a poor choice if your computer has only one available USB-C port and you need that same port to supply charging at your desk.

What to check on a computer or tablet

The manufacturer names MacBook Pro and Air, Surface Book 2, XPS 15 and 17, and several iPad families among compatible devices. Its description also covers USB-C or Thunderbolt laptops, tablets and phones. For a computer, the practical requirement is a working USB data connection; this hub does not depend on a video-capable USB-C port because it has no video output.

A tablet introduces another decision: whether its operating system and the accessory you connect support the work you intend to do. A physically fitting USB plug is not a promise that every printer, specialist interface or software-controlled device will work on an iPad. The maker's broad family list also should not be read as a model-by-model endorsement of every later Apple chip.

Who should choose a different arrangement?

Choose a multiport dock instead if the same purchase must provide HDMI, Ethernet, memory-card access or laptop charging. Choose a hub with documented downstream USB-C data ports if your newer storage drives have USB-C plugs and you want to avoid adapters. Neither task is the 70336's role.

The 70336 makes most sense as a small companion to an otherwise complete setup: four USB-A accessories, one USB-C host connection and clear separation between peripheral power and laptop power. Its value is easy access to those ports. It should be selected for that fit, rather than for power or display functions it does not offer.
