Vention USB 2.0 A Male to Micro-B Male 3A Cable 2M Black

The Vention USB 2.0 A Male to Micro-B Male 3A Cable 2M Black provides reliable data transfer and charging connectivity between USB Type-A host devices and Micro-USB equipped peripherals. It serves users who need a longer-than-standard cable for charging smartphones, tablets, portable speakers, power banks, and other Micro-USB devices from desktop computers, wall adapters, or USB hubs. The 2-meter length suits bedside charging, desk setups where the power source sits away from the device, and workbench applications requiring extended reach without signal degradation.

Use Cases and Applications

Bedside and Overnight Charging

The 2-meter length allows users to charge Micro-USB devices comfortably from a bedside table outlet or USB charging station without the device being pulled taut against the cable. Night stands positioned away from wall outlets particularly benefit from this extended reach. The 3A current rating ensures compatible devices charge at their maximum supported rate overnight rather than trickling slowly through an undersized cable.

Desktop Workstation Connectivity

Professionals connecting Micro-USB peripherals such as external hard drives, audio interfaces, MIDI controllers, and drawing tablets to desktop computers benefit from the cable’s combined data and power capability. The 2-meter length accommodates tower computers positioned on the floor beside the desk, where shorter cables create inconvenient routing. USB 2.0 speeds at 480Mbps adequately support audio interfaces, input devices, and moderate-speed storage peripherals.

Portable Power Bank Charging

Users recharging portable power banks from wall adapters or computer USB ports benefit from the 3A rating, which maximizes charging speed on power banks supporting higher input currents. Many power banks accept 2A or greater input charging, meaning cable current capacity directly affects recharge time. The Vention cable’s 24AWG power conductors minimize resistive losses that would otherwise reduce effective current delivery over the 2-meter length.

Workshop and Workbench Applications

Electronics hobbyists, makers, and repair technicians use Micro-USB connections extensively for programming microcontrollers, flashing firmware on development boards, and powering Arduino and similar platforms. The 2-meter cable provides comfortable working distance between the host computer and the workbench area. Additionally, the flexible PVC jacket tolerates the repeated coiling and uncoiling typical of workshop environments without developing stress fractures at the connector joints.

Audio and Entertainment Equipment

Portable Bluetooth speakers, wireless headphones, and desktop LED lighting systems commonly use Micro-USB charging ports. Users connecting these devices to USB charging hubs or computer ports benefit from the extended reach when the equipment sits at a distance from available USB ports. The cable handles both charging and, where applicable, firmware update connections for audio equipment requiring occasional computer connectivity.

Field and On-Site Service Work

Technicians servicing point-of-sale terminals, handheld scanners, ruggedized tablets, and industrial handhelds frequently encounter Micro-USB charging and data ports. The 2-meter length reduces awkward positioning during firmware updates or data extraction procedures when the host computer cannot be placed immediately adjacent to the equipment being serviced. The durable construction withstands the handling demands of field service environments better than thin consumer-grade cables.

Compatibility Considerations

The Micro-B USB connector on the Vention USB 2.0 A Male to Micro-B Male 3A Cable is physically incompatible with USB-C ports found on newer smartphones and laptops. Users with devices that have transitioned to USB-C connectors require a different cable type. However, the vast majority of Micro-USB devices manufactured before 2019 remain compatible, including many still-active product categories such as power banks, Bluetooth accessories, and industrial handhelds.

The 3A current rating represents the cable’s capacity rather than a guaranteed delivery amount. Actual charging current depends on the charger’s output rating and the connected device’s charging circuit. For instance, a device that accepts only 1A input will draw 1A regardless of the cable’s 3A rating. However, using a 3A-rated cable with a high-output charger and a compatible device ensures the cable itself never becomes the limiting factor in charging performance.

Data transfer speeds operate at USB 2.0 maximums of 480Mbps. This adequately supports most Micro-USB peripherals, as few devices in this category require the higher bandwidth of USB 3.0. Users transferring large video files from older Android devices should expect real-world speeds of 25-40MB/s depending on the storage speed of the connected device rather than the cable itself.

The 24AWG power conductors provide lower resistance than the 28AWG power wiring found in lower-quality alternatives. Over a 2-meter length, conductor gauge meaningfully affects voltage drop under load. Thinner 28AWG power conductors can cause sufficient voltage drop at 2A or higher currents to trigger some devices’ low-voltage charging protection, effectively reducing charge rate. The heavier gauge wiring in this cable avoids this issue at the rated 3A maximum.
