USB-A to DC Power Cable with 4 Barrel Connector Adapter Tips
A convenient 5V USB DC power cable kit with five connector-size options for powering compatible
5V electronic devices from a standard USB-A power source.
One USB Power Cable – Five DC Connector Sizes
The BiXPower CAB-Z4K4 is a versatile USB-A to DC barrel power cable kit designed
for compatible 5V DC electronic devices. Instead of carrying several different
USB power cables, this kit combines one Z4 USB power cable with four interchangeable connector
tips to support several commonly used DC barrel jack sizes.
The base Z4 cable has a USB Type-A male connector on the input side and a
4.0 × 1.7 mm male DC barrel connector on the output side. Use the cable directly
with a compatible 4.0 × 1.7 mm device, or attach one of the included adapter tips to change the
output connector size.
Key Features
- USB Type-A power input – connects to a standard USB-A power source
- Five available DC connector sizes using the cable and included tips
- 4.0 × 1.7 mm connector built directly into the Z4 cable
- Includes 5.5 × 2.5 mm adapter tip
- Includes 5.5 × 2.1 mm adapter tip
- Includes 3.5 × 1.35 mm adapter tip
- Includes 2.5 × 0.7 mm adapter tip
- Interchangeable tips are quick and easy to attach
- Compact solution for home, office, travel, and portable electronics
Easy Interchangeable Connector System
The Z4 cable can be used directly with equipment that accepts a
4.0 × 1.7 mm DC barrel plug. When a different connector size is required,
simply attach the appropriate adapter tip to the 4.0 × 1.7 mm connector.
This modular design makes the cable useful for multiple compatible devices while reducing the
need to keep a separate USB power cable for every connector size.

Important: Check Your Device Voltage Before Use
This cable does not convert or increase voltage.
A standard USB-A power source normally provides 5V DC. Therefore, the device
connected to this cable must be designed to operate from the voltage supplied by your USB
power source.
Connector size alone does not determine compatibility.
Before connecting your device, verify its required input voltage, connector size, polarity,
and power/current requirements. Do not use this cable with a device that requires a different
voltage simply because the connector fits.
How to Check Compatibility
Before ordering or connecting the cable, check the power specifications printed on your device
or its original power adapter. For proper operation, the following requirements should be
compatible:
- Voltage: The device must accept the voltage supplied by the USB power source, normally 5V DC.
- Connector size: Select the included barrel plug that correctly fits the device's DC input jack.
- Polarity: Confirm that the required DC polarity matches your power source and cable connection.
- Current / power: The USB power source must be capable of supplying sufficient current for the device.
If you are uncertain about compatibility, compare the voltage and connector specifications
with your device before use.
Understanding DC Barrel Connector Sizes
DC barrel connector dimensions are normally listed as
outside diameter × inside diameter.
For example, a 5.5 × 2.5 mm connector has an outside diameter of 5.5 mm
and an inside diameter of 2.5 mm.
Similarly, the Z4 cable's 4.0 × 1.7 mm connector has an approximately
4.0 mm outside diameter and 1.7 mm inside diameter.

A Convenient USB Power Solution
The CAB-Z4K4 is useful when you need to power compatible low-voltage electronics from a
USB-A power source but encounter different DC barrel connector sizes. Its interchangeable
connector system makes it a convenient accessory for compatible portable electronics,
small electronic devices, travel setups, and other 5V DC applications.
Note: Device compatibility depends on voltage, polarity, connector dimensions,
and power requirements. Always verify your device specifications before connecting power.
