UGREEN US184 USB-A to USB-C 5 Gbps Cable, 2 m (20884)

Overview

The UGREEN US184 (20884) is a 2 m cable with a USB-A plug for a computer or charger and a USB-C plug for the device. It connects USB-C phones, drives, cameras and card readers to a USB-A port for charging and fast file transfer, at up to 5 Gbps and up to 3 A.

Is it right for you?

• Suits a USB-C phone or tablet with a USB-A computer, charger or power bank, and USB-C SSDs, cameras and card readers that stay within the port’s power.
• It does not charge a USB-C laptop at its normal USB-C Power Delivery (PD) wattage, because the source end is USB-A.
• It carries no DisplayPort Alt Mode, HDMI, Thunderbolt or USB4 video. Choose a display, Thunderbolt or USB4 cable for a monitor or dock.
• Both ends are plugs, so it is not an OTG adapter for a USB-A accessory.
• A charge-only USB-A port, for example in some cars, stays charge-only.

Key features

• USB 3.0 (USB 3.2 Gen 1) data up to 5 Gbps when both ports and the device support it, with fallback to USB 2.0 speed on an older host.
• Charging current up to 3 A from a compatible USB-A charger or host; the device sets the current and voltage it accepts.
• QC, AFC or FCP fast charging only when the charger and device both use the same mode.
• 56 kΩ pull-up resistor for correct USB-A to USB-C operation.
• Tinned copper conductors with shielding in a black PVC jacket, 2 m long.
• No cable driver; works at the cable layer with Windows, macOS, ChromeOS, Linux and Android.

What else you need

A USB-A port on a computer, charger or power bank and a USB-C device. File access on a phone may need unlocking, a trust prompt or the maker’s transfer setting. A bus-powered SSD needs a port that can supply its power; if it disconnects, use a powered arrangement rather than reconnecting repeatedly.

Before you buy

• Confirm that both ends support USB 3.x if you need 5 Gbps data, and that the USB-A source can supply the current and charging mode the device needs.
• Confirm that 2 m suits the route without tension or excess cable.
• In a car, route the cable away from pedals, steering controls, gear selectors and sharp trim. Vehicle USB ports vary widely.
• Stop using it if a connector, jacket or plug is bent, cracked, loose, scorched or unusually hot. Keep connectors dry and free of lint or metal. Never splice, crush or tightly knot it.
