C13 Right Angle DC Power Connector Tip – 6.5 x 3.0mm Male to 5.5 x 2.5mm Female
The BiXPower C13 DC power connector tip converts a
standard 5.5 x 2.5mm male barrel connector into a
6.5 x 3.0mm male DC connector. Its compact
right-angle design is useful when space behind the device is limited
or when a straight connector would place unnecessary stress on the
power connection.

This connector tip can be used with compatible BiXPower batteries,
power adapters, DC power cables, and other power sources equipped
with a 5.5 x 2.5mm male output connector.
Key Features
- Output connector: 6.5mm outer diameter x 3.0mm inner diameter male barrel plug
- Input connector: 5.5mm outer diameter x 2.5mm inner diameter female jack
- Right-angle design helps reduce cable protrusion and connector strain
- Simple plug-in design – no tools or wiring required
- Useful for compatible laptops and other DC-powered electronic equipment
- Compact and reusable connector adapter

Please verify the connector dimensions before ordering.
Device model numbers alone are not always sufficient to determine connector
compatibility. Compare your existing power connector with the dimensions
and photos shown on this page.
5.5 x 2.5mm Female Input
The rear input of the C13 connector tip is a
5.5 x 2.5mm female DC jack. It is designed to accept a
standard 5.5 x 2.5mm male barrel connector.

How to Use the C13 Connector Tip
Using the C13 is simple. Insert a compatible
5.5 x 2.5mm male power plug into the female jack on the
C13 adapter. The other end of the C13 then provides a
6.5 x 3.0mm male connector for your compatible device.
Connection Sequence
- Confirm that your power source uses a 5.5 x 2.5mm male DC connector.
- Insert the 5.5 x 2.5mm male plug fully into the female jack of the C13 connector tip.
- Connect the C13's 6.5 x 3.0mm male plug to your compatible device.
- Before applying power, verify that the voltage and polarity are correct for your device.
Important – This Connector Does Not Convert Voltage
The C13 is a physical connector adapter only. It does not
increase, decrease, regulate, or otherwise change the voltage supplied by
your battery or power adapter.
Before connecting your equipment, make sure the
output voltage, connector polarity, and available current
from the power source are compatible with your device. Using an incorrect
voltage or polarity may damage the connected equipment.
Important Compatibility Information
The C13 connector tip requires a
5.5 x 2.5mm male connector on the power-source side.
If your battery, AC/DC adapter, or power cable does not provide a
5.5 x 2.5mm male connector, this C13 tip cannot connect directly to it.
When using the C13 with certain universal batteries or universal power
adapters, first install the appropriate 5.5 x 2.5mm output connector on
the battery or adapter cable. The C13 can then be connected to that plug
to create the required 6.5 x 3.0mm output connection.
Compatible Device Guidance
The 6.5 x 3.0mm connector size has been used on various Toshiba
Satellite, Portege, Tecra, Qosmio and other laptop models. However,
manufacturers may use different connector sizes even within the same
product family.
For this reason, we recommend selecting this connector by
physical connector size rather than laptop model number alone.
Please confirm that your device requires a 6.5mm outer diameter x
3.0mm inner diameter DC power plug before ordering.
Ideal for Power Adapter and Battery Applications
The C13 provides a convenient way to adapt a common 5.5 x 2.5mm DC power
connection for equipment requiring a 6.5 x 3.0mm plug. It can be useful
with compatible portable batteries, universal power supplies, replacement
laptop power adapters, DC power systems, and test or service applications.
Its right-angle configuration can also help keep the connection more
compact where clearance behind or beside the powered device is limited.
