BiXPower CNT-D3 – 5.5 × 2.5mm Female to
5.5 × 2.1mm Right Angle DC Power Connector Adapter
The BiXPower CNT-D3 is a compact,
flexible DC power connector adapter designed to
convert a standard 5.5 × 2.5mm male DC
barrel connector into a
5.5 × 2.1mm right-angle male connector.
Its 90-degree design helps save space behind
electronic devices, while the short flexible cable
allows easier positioning and reduces the need
for a rigid, straight connector arrangement.
Key Benefits
- Converts 5.5 × 2.5mm male DC plugs to
5.5 × 2.1mm right-angle male plugs.
- Compact 90-degree connector requires approximately
17mm (0.7 inches) of clearance.
- Protective sleeve on the female connector helps
provide a secure fit and reduce dust and moisture
entry at the connection.
- Flexible 16 AWG cable makes installation easier.
- Approximately 120mm (5 inches) overall length.
- Passive DC connector adapter; no voltage conversion.
Why Choose the CNT-D3 Right Angle Adapter?
1. Compact 90-Degree Connector Saves Space
Many electronic devices have DC power input ports
located on the rear or side of the device.
A conventional straight DC power plug may require
additional space behind the equipment.
The CNT-D3 features a compact
5.5 × 2.1mm right-angle male connector
that requires approximately
17mm (0.7 inches) of clearance
at the plug.
This makes it useful for devices installed near
walls, inside cabinets, on shelves, or in other
space-limited locations.
2. Improved Female Connector with Protective Sleeve
The CNT-D3 includes a
5.5 × 2.5mm female DC jack
with a protective sleeve designed to fit securely
around a compatible male power connector.
The sleeve helps maintain a stable physical
connection and provides additional protection
against dust and incidental moisture at the
connector interface.
This design is particularly useful when connecting
external DC power supplies, rechargeable batteries,
or DC power cables.
Note: The sleeve provides added
protection but does not make the connector
waterproof. Avoid exposure to rain or water.
3. Flexible Cable for Easier Installation
Unlike rigid barrel connector adapters,
the CNT-D3 features a short
16 AWG flexible cable
between its male and female connectors.
The cable allows the two connector ends to be
positioned independently, making it easier to
connect equipment when the available space or
cable routing is limited.
The flexible design can also help reduce
mechanical stress caused by a heavy or
poorly positioned external power cable.
How the CNT-D3 Works
The CNT-D3 is a passive DC power connector
adapter. It changes the physical connector size
and orientation without changing the supplied
voltage.
Input Connection:
5.5 × 2.5mm male DC power plug connects
to the CNT-D3 female jack.
Output Connection:
CNT-D3 provides a 5.5 × 2.1mm right-angle
male DC plug for a compatible device.
Connector Conversion:
5.5 × 2.5mm Male DC Plug
→ CNT-D3 Adapter
→ 5.5 × 2.1mm Right-Angle Male DC Plug
The adapter does not increase, decrease,
or regulate the input voltage.

Typical Applications
The CNT-D3 can be used with compatible DC-powered
equipment, including:
- DC-powered electronic devices
- Rechargeable battery power connections
- AC-to-DC power adapter cables
- DC-to-DC converter output cables
- LED lighting systems
- Networking and communication equipment
- Electronic devices installed in limited spaces
- Custom DC power cable assemblies
Always verify the required connector dimensions,
power supply voltage, polarity, and current
requirements before use.
Important Compatibility Information
Please Verify Before Connecting
- The input side accepts a compatible
5.5 × 2.5mm male DC barrel plug.
- The output side is a
5.5 × 2.1mm right-angle male DC plug.
- This adapter does not convert voltage.
The connected power source must provide
the voltage required by your device.
- Verify that the power source polarity
matches your device requirements.
- Confirm that the complete power connection,
including the connectors, is suitable
for the required operating current.
- Do not use this adapter with incompatible
connectors or damaged power cables.
CNT-D3 vs. CNT-C3 Connector
The BiXPower CNT-D3 provides the same basic
connector conversion function as the
BiXPower CNT-C3: adapting a
5.5 × 2.5mm male DC plug to a
5.5 × 2.1mm male DC plug.
The CNT-D3 adds several design improvements:
- A protective sleeve on the female connector
for a more secure connection.
- A more compact right-angle male connector
for space-limited applications.
- A flexible cable between the two connector
ends for easier positioning.
If you need a compact, flexible right-angle
DC connector adapter, the CNT-D3 is an
excellent alternative to the CNT-C3.

Frequently Asked Questions
Q: Does the CNT-D3 change the output voltage?
No. The CNT-D3 is a passive connector adapter.
It changes the physical connector configuration
but does not convert or regulate voltage.
Q: Can I use the CNT-D3 with a rechargeable battery?
Yes, provided the battery has a compatible
5.5 × 2.5mm male DC power connector and its
output voltage, polarity, and current capability
meet the connected device's requirements.
Q: What is the difference between
5.5 × 2.5mm and 5.5 × 2.1mm connectors?
Both connectors have a nominal outer barrel
diameter of 5.5mm, but their inner diameters
are different: 2.5mm and 2.1mm.
The CNT-D3 provides a physical conversion
between these two connector sizes.
Q: Why use a right-angle connector?
A right-angle connector allows the cable to
route sideways instead of extending straight
out from the device, helping save space and
improve cable management.
Q: Is the CNT-D3 waterproof?
No. The protective sleeve helps reduce exposure
to dust and incidental moisture, but the
connector is not rated as waterproof.
Q: Can I use the CNT-D3 instead of CNT-C3?
For applications requiring the same
5.5 × 2.5mm female to 5.5 × 2.1mm male
connector conversion, the CNT-D3 may be
used as an alternative, subject to electrical
and mechanical compatibility.
