Cigarette Lighter Female Socket to 5.5 × 2.5mm Male DC Power Adapter Cable
Convert a standard cigarette-lighter-style male power plug
to a 5.5 × 2.5mm male DC barrel connector with this compact
BiXPower adapter cable.
This adapter is useful when your power source or car power cable has a
cigarette-lighter-style male plug, but the device you want to power uses a
5.5mm OD × 2.5mm ID DC input jack.
Key Features
- Cigarette lighter female socket on one end
- 5.5 × 2.5mm male DC barrel connector on the other end
- 5.5mm outside diameter / 2.5mm inside diameter barrel plug
- Compact adapter cable for DC power applications
- Allows many cigarette-lighter-style power cables and adapters to connect to equipment with a compatible DC input jack
- Can be used with optional connector tips for additional DC connector sizes
- Optional 5.5 × 2.1mm adapter available

5.5 × 2.5mm DC Barrel Connector
The male DC barrel plug has an approximately
5.5mm outside diameter and 2.5mm inside diameter.
Before ordering, check your device's DC input jack size to make sure the
connector is compatible.
How to Use This Adapter
Insert a compatible cigarette lighter male power plug into the
female socket on the CF525M. The other end of the adapter then provides a
5.5 × 2.5mm male DC barrel plug for connection to a compatible
device.
This makes the adapter convenient for reusing compatible car power cables,
DC power adapters, battery cables, and other power accessories that terminate
in a cigarette-lighter-style male plug.
Optional Connector Tips for Other DC Jack Sizes
Need a different DC connector size? The standard
5.5 × 2.5mm male barrel connector can be used with compatible
optional BiXPower connector tips to adapt it to other DC plug sizes.
Please Note: Optional connector tips are not included with the
standard CF525M adapter unless specifically selected or purchased separately.
Always verify the required connector dimensions and polarity before connecting
your equipment.
Does Your Device Use 5.5 × 2.1mm Instead?
The outside diameter of both 5.5 × 2.5mm and
5.5 × 2.1mm connectors is approximately 5.5mm, so the two
sizes can look very similar. The difference is the inside diameter of the
barrel connector.
If the standard 5.5 × 2.5mm plug fits into your device's
power jack but the connection feels too loose, your device may use a
5.5 × 2.1mm DC jack.
In that situation, you can select or purchase the optional
5.5 × 2.1mm adapter to convert the CF525M's 5.5 × 2.5mm
connector to a 5.5 × 2.1mm connector.
Helpful Tip:
5.5 × 2.5mm and 5.5 × 2.1mm DC connectors can look nearly identical.
If your existing plug goes into the jack but does not make a secure connection,
check whether your device requires the smaller 2.1mm center size.
Important: This Cable Does Not Convert Voltage
The CF525M is a connector adapter cable only. It changes the
physical connector format but does not increase, decrease, or regulate
the input voltage.
The voltage supplied through the cigarette lighter socket will be passed to the
DC barrel connector. Your power source must provide the correct voltage required
by the connected equipment.
Before Connecting Your Device:
Verify the required input voltage, connector size, polarity, and power
requirements of your equipment. Using an incorrect voltage or polarity
may damage the connected device.

Typical Applications
This DC power connector adapter can be useful with compatible:
- Portable battery systems
- Car power adapters
- DC power supplies
- DC-to-DC power converters
- Portable electronics
- Mobile equipment
- 12V and other compatible DC-powered devices
- Custom DC power installations
Compatibility depends on the voltage, polarity, connector dimensions,
and power requirements of your specific equipment.
A Simple Way to Adapt a Cigarette Lighter Power Connection
The BiXPower CF525M provides a convenient way to connect a
cigarette lighter male power cable to equipment using a
5.5 × 2.5mm DC power jack. Its compact design makes it easy to keep
with your battery, car power accessories, or portable DC equipment.
For equipment using other DC connector sizes, compatible optional connector
tips provide additional connection flexibility without requiring a completely
different power cable.
Compatibility Checklist
- Confirm your device accepts the voltage supplied by your power source.
- Confirm the required DC plug size.
- Confirm connector polarity before use.
- Make sure the power source can provide sufficient current for your device.
- Do not assume connector compatibility means electrical compatibility.
