UGREEN Uno X688 100W 4-Port GaN USB-C Charger

UGREEN Uno X688 is a four-port GaN wall charger with a claimed maximum single-port USB-C output of 100W. Its robot-shaped design includes a TFT screen for charging-state expressions, while the listing also describes charging up to four devices at once.

At a glance

  • The listing says USB-C1 or USB-C2 can provide up to 100W when used alone. It does not specify the power allocation when several ports are in use.
  • Three USB-C ports and one USB-A port are claimed to support charging up to four devices simultaneously, with power distributed between ports.
  • The TFT screen is described as showing expressions linked to charging states. Expressions appear only while power is on.
  • The manufacturer lists compatibility with laptops, smartphones and tablets, but device charging speed depends on the device and charging protocol.

What to know before buying

Listing details to confirm

The listing is inconsistent about capacity: the title and product details say 100W, while a feature paragraph calls it a compact 65W charger and another describes it as a 65W charger. The 100W single-port claim applies to USB-C1 or USB-C2 only, and multi-port power sharing is not specified. Port totals also conflict: the listing says four ports overall, with three USB-C and one USB-A, but separately lists one USB 2.0 and two USB 3.0 ports without clearly mapping those counts to connector types. Confirm the selected listing’s output and port details before purchase. The screen is identified as TFT in derived listing data, while the feature copy describes a screen without naming its technology.

Customer feedback describes the charger as quick, reliable and handy for travel, with positive comments about its appearance and its performance with multiple connected devices. That feedback is relevant to its four-port layout, but it does not resolve the listing’s conflicting 100W and 65W claims or establish multi-port power levels. Opinions on price are mixed, so buyers may want to weigh the display and extra ports against their charging needs.

Positive themes

  • Customers describe charging as quick and the adapter as reliable.
  • Feedback appreciates the appearance, portability and ability to use several ports.

Negative themes

  • Some customers consider the charger a bit pricey.

Mixed feedback

  • Feedback is divided on whether the price feels worthwhile.

Frequently asked questions

Does this charger provide 100W to every port?

No. The listing claims up to 100W from USB-C1 or USB-C2 when one device is connected. It does not give the per-port output when multiple devices are charging.

How many devices can it charge at once?

The feature listing says it can charge up to four devices at once using three USB-C ports and one USB-A port. It does not specify how the available power is divided.

Does the listing consistently state the charger’s wattage?

No. The title and several details say 100W, but a feature paragraph also describes the charger as 65W. Check the selected product listing to confirm the intended model and output.

What is included?

The package contents list specifies one adapter.
