The UGREEN 55618 USB-C OTG Adapter is a compact USB-A male to USB-C female adapter designed to bridge older USB-A ports with newer USB-C cables and peripherals. It is a practical accessory for users who have USB-A chargers, computers, car chargers or other USB-A ports but need to connect a USB-C cable or compatible USB-C device.

The UGREEN 55618 supports USB 3.1-class data transfer up to 10Gbps and charging up to 3A, according to current product specifications. Its compact PC construction and small footprint make it easy to carry as an everyday adapter.

It is important to understand the connector direction: USB-A male → USB-C female. This means the USB-A end plugs into an existing USB-A port, while the USB-C female port accepts a USB-C cable or compatible USB-C accessory.

Detailed Description

As more smartphones, tablets, headphones, power banks and other accessories move toward USB-C, many users still have older USB-A chargers, laptops, desktop computers and car chargers.

The UGREEN 55618 provides a simple solution by converting a standard USB-A port into a USB-C female connection.

For example, you can connect a USB-C charging cable to an older USB-A charger through the adapter. You can also use compatible USB-C peripherals with USB-A equipment where the device and cable support the required functionality.

The adapter features a USB-A male connector on one side and a USB-C female connector on the other. Its compact design makes it particularly useful as a travel adapter or as a permanent accessory kept with your charger or laptop bag.

USB-A to USB-C Conversion

The primary purpose of UGREEN 55618 is straightforward:

USB-A Port → UGREEN 55618 → USB-C Cable / Compatible USB-C Device

This allows you to continue using USB-A equipment while accommodating newer USB-C accessories.

It can be useful with:

• USB-A wall chargers
• USB-A laptop ports
• Desktop computers
• Car chargers
• USB-A power banks
• USB-A charging hubs
• USB-C charging cables
• Compatible USB-C peripherals

---

Up to 10Gbps Data Transfer

The UGREEN 55618 is specified with a USB 3.1 interface and data transfer support up to 10Gbps.

This makes it considerably more capable than basic USB 2.0 adapters.

However, actual transfer speeds depend on both connected devices, the USB port, cable and peripheral. If any component is limited to a slower USB standard, the connection will operate at that lower speed.

UGREEN also notes that if the maximum transfer speed isn't achieved, reversing and reconnecting the USB-C cable can help establish the intended connection, provided the cable and connected equipment support the required speed.

---

Supports Up to 3A Charging

The adapter supports charging up to 3A, according to the product specifications.

This makes it useful for connecting USB-C charging cables to compatible USB-A power sources.

However, the adapter should not be considered a universal high-wattage USB-C fast charger. Actual charging power depends on the charger, cable, connected device and supported charging protocol.

For example, a USB-A charger connected through the adapter cannot automatically provide USB-C Power Delivery simply because the connector has been converted.

---

Compact and Portable

The 55618 has a very small form factor, with listed dimensions of approximately 15.4 × 8 × 16 mm, excluding the USB connector.

Its compact design makes it easy to:

• Keep in a laptop bag
• Carry while travelling
• Store with charging accessories
• Leave connected to a USB-A charger
• Keep as an emergency adapter

It takes up very little space compared with larger USB hubs or adapters.

---

Durable Construction

The adapter uses a PC housing and is designed for frequent everyday use. Current product specifications state that the connector is designed for up to 10,000 plug/unplug cycles.

This makes it suitable for users who regularly switch between USB-A and USB-C equipment.

---

Wide Compatibility

The UGREEN 55618 can be used with a variety of USB-A and USB-C equipment, including compatible:

• Smartphones
• Tablets
• Laptops
• Desktop PCs
• USB chargers
• Car chargers
• USB-C cables
• Flash drives
• Other USB-C peripherals

Current Pakistani listings specifically mention compatibility with devices such as newer iPhone models, Samsung Galaxy smartphones, iPads and AirPods, although exact functionality depends on the connected device and accessory.

---

Plug and Play

No separate driver installation is required for the adapter itself.

It is a passive/compact connector solution designed to work when the connected USB-A port, USB-C cable and device support the required function.

Simply connect the adapter and then connect your USB-C cable or compatible accessory.

---

Useful for Older USB-A Chargers

One of the most convenient applications is extending the usefulness of older USB-A chargers.

If you have a charger with a traditional USB-A output but your current cable uses USB-C, the UGREEN 55618 can provide the physical connection needed.

This can help reduce the need to replace every older charger immediately.

---

Useful for USB-A Computers

Desktop and laptop computers may still provide USB-A ports alongside USB-C.

The 55618 allows compatible USB-C cables and accessories to be connected to a USB-A port.

This can be useful for:

• Data transfer
• Charging
• Connecting compatible USB-C accessories

Actual functionality depends on the USB-A port and connected device.

---

Important: It Is Not a USB-C to USB-A Adapter

The connector direction matters.

The UGREEN 55618 is:

USB-A Male → USB-C Female

It is not:

USB-C Male → USB-A Female

If you want to connect a USB-A peripheral such as a USB flash drive, keyboard or mouse to a USB-C phone or laptop, you need the opposite adapter configuration.

For example:

This is different from:

USB-C Laptop/Phone → USB-C-to-USB-A Adapter → USB-A Flash Drive

For the second application, you need the opposite adapter type.

Also, although the adapter is specified for up to 10Gbps, the actual speed is determined by the complete connection.
