BiXPower C24 DC Power Connector Tip – 7.4 x 5.08mm Male with Center Pin for HP/Compaq
The BiXPower C24 (CNT-C24) is a compact right-angle DC power connector tip designed for compatible HP and Compaq laptop computers requiring a 7.4mm outside diameter x 5.08mm inside diameter male DC barrel connector with center pin. This connector sometimes is described as 7.4 × 5.0mm connector
The C24 attaches to an existing
5.5 x 2.5mm male DC power plug,
allowing a compatible rechargeable battery,
universal power adapter, or DC power cable
to connect to equipment using the larger
HP/Compaq-style power connector.
Important: This connector is not compatible with Dell laptop computers, although it has exactly same physical size as some Dell computer power adapters. We have CNT-C27 for Dell computers.

Product Overview
BiXPower CNT-C24 DC power connector tip
Laptop power connectors vary in size and design.
The BiXPower C24 provides a convenient connector
interface for certain HP and Compaq computers
that use a 7.4 x 5.08mm DC power input
with a center pin.
Instead of replacing an entire compatible
power cable, you can attach the C24 connector
tip to a 5.5 x 2.5mm male plug.
The C24 is intended for use with compatible
external batteries and power adapters.
It does not convert voltage or provide
electronic power regulation.

Compatibility notice:

not guaranteed compatibility confirmations.
Some laptops within the same family
use different connectors or electrical requirements.
Always compare your laptop's original connector,
center-pin design, voltage, and power requirements
before ordering.
Important Difference: C24 vs. Right-Angle Converter
BiXPower C24:
Designed to convert a 5.5 x 2.5mm
male power plug into a 7.4 x 5.08mm
male connector with center pin.
BiXPower LC90:
Designed for customers who want
to change the orientation of a compatible
HP/Compaq-style connector from straight
to right angle.
If your existing power adapter already
has a 7.4 x 5.08mm HP-style connector,
the C24 is not the correct product
for simply changing its angle.

Important Electrical Compatibility Information
The C24 changes the physical connector only.
It does not increase, decrease, regulate,
or otherwise convert DC voltage.
Many older HP/Compaq laptops in the historical
compatibility list use approximately
18V to 19V DC, but the required voltage
and power capacity vary by model.
Always follow the specifications
printed on your laptop or original adapter.
The center pin may be used for power-adapter
identification or another electrical function.
A connector that physically fits does not
necessarily guarantee charging compatibility.
Do not use the C24 if your original
power cable does not have a compatible
5.5 x 2.5mm male connector.
Frequently Asked Questions
What does the BiXPower C24 connector do?
It converts a 5.5 x 2.5mm male DC power plug
into a 7.4 x 5.08mm male DC connector
with center pin for compatible equipment.
Will the C24 work with every HP laptop?
No. HP laptops use several different
power connector designs.
Verify the connector size,
center pin, and electrical requirements
for your specific laptop model.
Does the C24 convert 12V into 19V?
No. The C24 is a passive connector tip.
Your power source must already provide
the correct voltage required by your laptop.
Can I use the C24 with a rechargeable battery?
Yes, if the battery has a compatible
5.5 x 2.5mm male output connector
and supplies the correct voltage,
polarity, and power capacity.
Laptop charging may also depend
on adapter identification requirements.
Can I use the C24 to change my HP charger plug to a right-angle plug?
Not if your charger already has the
7.4 x 5.08mm HP-style male connector.
The C24 is intended for use with a
5.5 x 2.5mm male power plug.
For straight-to-right-angle conversion,
look for the appropriate LC90 connector.
What is the center pin used for?
The center pin is part of the connector
design and may be used for adapter
identification or other electrical functions.
Its presence does not guarantee compatibility
with every laptop.
Does the package include a battery or power adapter?
No. The package includes one C24
connector tip only.
Batteries, power adapters, and cables
are sold separately.
