SKU CH-HDHF-7JW82

Four adapters convert USB-C to USB 3.0 and USB 2.0 to USB-C for charging and data

  • TypeUSB to DisplayPort Adapters
  • Four adapters in one pack for versatile connectivity
  • Two USB-C to USB 3.0 female converters for legacy devices
  • Two USB 2.0 to USB-C female OTG adapters for modern ports
  • Fast charging up to 12 V at 1.5 A supported
  • LED indicators show green when power is sufficient

4-Pack USB-C & USB 2.0 Gender Changers

This set contains two USB-C male to USB 3.0 female converters and two USB 2.0 male to USB-C female OTG adapters. It suits users who need to connect legacy USB-A peripherals to modern USB-C hosts and vice versa. The silver finish matches common laptop aesthetics.

Charging and data limits per adapter type

The USB-C to USB 3.0 adapters support fast charging at 5V/3A, 9V/2A and 12V/1.5A alongside data transmission. The USB 2.0 to USB-C adapters operate at USB 2.0 speeds and do not support the higher power profiles. Both adapter types include LED indicators that flash red for insufficient power and show solid green when supply is adequate.

Simple plug-in installation with one common issue

Adapters require no drivers; insert them between the cable and the port for immediate use. The main problem arises when users expect the USB 2.0 adapters to deliver fast charging or USB 3.0 data rates, which they cannot. Build quality uses ABS and copper for durability.

Questions about this item

Should I choose the USB 3.0 or USB 2.0 adapters from this 4-pack?

The pack contains two of each; use the USB 3.0 female adapters when you need faster data rates and the USB 2.0 female OTG adapters for basic charging or legacy peripherals.

What does the 5V/3A 9V/2A 12V/1.5A rating mean when I plug this into my laptop?

It shows the maximum power the adapter can pass through — up to 12 volts at 1.5 amps — so your laptop or power bank can charge at the highest speed the connected device negotiates.

How does the USB 3.0 female port limit real-world transfer speed?

The USB 3.0 female connector caps the link at 5 Gbps, so even if the host supports a faster standard the adapter will not exceed that ceiling.
