  • Real-time voltage, current and wattage monitoring via built-in LED display
  • Up to 10Gbps data transfer with USB3.2 Gen2, backward compatible with 3.0, 2.0 and 1.1
  • PD fast-charging pass-through while simultaneously monitoring power parameters

Three-Pack USB-C to USB-A Converters

This set supplies three USB-C to USB 3.2 Gen 2 Type-A adapters so you can keep one at a desk, one in a bag and one as a spare for testing or replacement. Each unit is plug-and-play and requires no driver installation on macOS, iPadOS, Android or Windows devices. The bundle suits home users, office workers and technicians who need multiple converters for daily connectivity and diagnostics.

Smart LED Power Readout

A built-in digital display shows real-time voltage, current and charging wattage, turning every adapter into a portable USB power tester for checking charger health or cable quality. It supports mainstream QC and PD fast-charge protocols and passes power through to smartphones, tablets and small notebooks while monitoring the parameters. Data transfer reaches 10 Gbps, twice the speed of USB 3.0, and remains backward compatible with USB 2.0 and 1.1 peripherals.

Compact Port Expansion

The lightweight design adds a full-size USB-A port to any USB-C laptop, tablet, phone or handheld console without blocking adjacent ports. It enables flash drives, mice, keyboards, card readers and portable SSDs to connect instantly while the LED screen frees you from guessing whether a charger or cable is delivering the expected power. No external power supply or software is required for operation.

Questions about this item

How much clearance does the LED display add beyond a standard USB-A port?

The built-in LED screen sits inline with the adapter body, so it needs the same front clearance as any USB-A plug plus the screen thickness.

Is any driver or firmware step required before the power readout works?

No driver is needed; the LED readout activates automatically when the adapter detects voltage on the USB-C host port.

What wears out first on the adapter — the USB-A socket or the USB-C plug?

Both connectors are rated for standard USB mating cycles; the USB-A socket typically sees more insertions, so it tends to wear before the USB-C plug.
