Type-C USB Fast Charge Cable – 20cm

Description

A USB-A to USB-C cable, such as the 20cm (approx. 8-inch) version shown in your image, is a versatile and common accessory used for charging. While specific technical performance can vary by manufacturer, here are the standard technical specifications typical for this type of short cable:

General Technical Specifications

• Connectors: USB-A (Male, host side) to USB-C (Male, device side).
• Cable Length: 20 cm (approx. 8 inches).
• Standard Compliance: Most cables of this length are compliant with the USB 2.0 standard, though some higher-quality variants may support USB 3.0/3.1 speeds.
• Data Transfer Speed:
  • USB 2.0: Typically, up to 480 Mbps.
  • USB 3.0/3.1: Can support up to 5 Gbps or 10 Gbps (look for blue internal plastic on the USB-A end or specific branding on the packaging for high-speed variants).
• Charging Capability: Supports standard power charging. With USB-A as the host, power delivery is generally limited by the output of the charger or the computer port you are plugging into (standard USB-A ports typically output 5V at 1A to 2.4A).
• Physical Features: Often features a braided or durable TPE jacket to prevent tangling, which is especially useful for short cables used in compact spaces or travel.

Important Considerations

• Directionality: USB-A is always the “host” end (plugged into your wall adapter, laptop, or power bank), and USB-C is the “device” end (plugged into your phone, headphones, or other peripherals).
• Compatibility: While the USB-C end is physically reversible and universal, the overall charging speed depends on the power output capability of the USB-A port you are connecting to.
• Safety/Durability: Short, high-quality cables like the one in your image often have reinforced strain relief at the neck of the connectors to prevent fraying, which is a common failure point in charging cables.

This type of cable is ideal for connecting devices in close proximity—such as connecting a smartphone to a laptop for data syncing or using a portable power bank to charge a phone in your pocket or a bag without excess cable clutter.
