BiXPower BX-CR15D 12V/24V Car DC Power Adapter with 5V USB Charging Port
Vehicle Cigarette Lighter Adapter with 5.5 x 2.5mm DC Output and 5V 2.4A USB-A Port
The BiXPower BX-CR15D is a versatile vehicle DC power adapter designed to provide both a DC barrel connector output and a 5V USB charging port from a compatible car or truck cigarette lighter power socket.
The adapter accepts 10V to 24V DC input, making it suitable for compatible 12V vehicle electrical systems and supported 24V DC power sources.
Its DC barrel connector passes through the input voltage without conversion, while the built-in USB-A port provides a converted 5V DC output with up to 2.4A of charging current.
Key Features
Two Convenient Power Outputs
One 5.5 x 2.5mm female DC barrel jack and one 5V USB-A charging port.
10V–24V DC Input
Designed for compatible vehicle cigarette lighter sockets and DC power systems within the supported voltage range.
Direct DC Power Pass-Through
The barrel output provides approximately the same voltage as the input source, without voltage conversion.
5V USB Charging
The USB-A output provides 5V DC at up to 2.4A, equivalent to a maximum nominal output of 12W.
Included DC Output Cable
Includes a 12-inch cable with 5.5 x 2.5mm male barrel connectors on both ends.
Optional Longer Cable
A 36-inch output cable option is available for installations requiring additional cable length.
Two Outputs for Different Power Requirements
Output 1: 5.5 x 2.5mm DC Barrel Connector
The DC barrel output passes through the voltage supplied by the cigarette lighter socket.
For example, when the input source supplies 12V DC, the barrel output will provide approximately 12V DC. If the source supplies 24V DC, the barrel output will provide approximately 24V DC.
Important: This output does not convert 24V to 12V or maintain a constant 12V output.
Use it only with devices that accept the actual input voltage and have compatible connectors and polarity.
Output 2: 5V USB-A Charging Port
The built-in USB port converts the input voltage to 5V DC for charging compatible USB-powered devices.
- Output Voltage: 5V DC
- Maximum Output Current: 2.4A
- Maximum Nominal Output Power: 12W
- Connector: Standard USB Type-A female port
The USB port can power or charge compatible smartphones, small electronics, and other devices that support standard 5V USB charging.
This is a standard 5V USB output, not a USB-C Power Delivery or USB fast-charging output.

Power Rating Note:
The DC output current rating does not guarantee that every vehicle socket or attached cable can safely supply that current. Actual usable current is limited by the lowest-rated component, including the vehicle fuse, socket, adapter, barrel connector, and output cable.
Included 12-Inch DC Output Cable
The standard BX-CR15D package includes a DC output cable approximately 12 inches (300mm) long.
The cable features 5.5 x 2.5mm male barrel connectors on both ends, allowing the adapter's female DC jack to connect to compatible electronic equipment.
The cable has a straight connector on one end and a right-angle connector on the other, helping with cable routing in installations where space is limited.
Optional Longer DC Output Cable
If additional cable length is required, a longer cable may be selected through the product options.
- Standard: 12-inch output cable included.
- Optional: 36-inch output cable available.
For other compatible cable options, see the BiXPower Z6 DC Power Cable, approximately 1 meter long, with 5.5 x 2.5mm male connectors.
Longer cables may increase voltage drop, especially at higher currents. Always confirm the wire gauge, connector rating, and power requirements of your application.
Typical Applications
- Powering compatible DC electronics from a vehicle cigarette lighter socket.
- Connecting equipment requiring a 5.5 x 2.5mm DC power input.
- Charging compatible 5V USB devices while using a separate DC-powered device.
- Providing convenient access to a vehicle's DC supply through a barrel connector.
- Using compatible 12V or 24V vehicle power systems for portable electronic equipment.
Important Compatibility Information:
The DC output voltage follows the vehicle's electrical system. Many nominal 12V vehicle systems can operate above 12V while the engine is running. Make sure your connected equipment accepts the actual voltage range.
How to Use the BX-CR15D
- Check that the vehicle's cigarette lighter socket supplies DC voltage within the adapter's 10V–24V input range.
- Confirm the connected device's required voltage, polarity, connector size, and current.
- Insert the BX-CR15D into the vehicle cigarette lighter power socket.
- Connect the included DC cable to the adapter's 5.5 x 2.5mm female output jack.
- Connect the other end to compatible equipment.
- If desired, connect a compatible USB device to the 5V USB-A output.
Some vehicles disable their cigarette lighter sockets when the ignition is turned off. In these vehicles, the socket may only supply power when the ignition is in the accessory or on position.
Important Electrical Safety Information
1. The DC barrel output does not convert voltage. Never connect a device that requires a lower voltage than the vehicle provides unless a suitable DC-to-DC converter is used.
2. Verify polarity. Connector size alone does not guarantee electrical compatibility.
3. Avoid short circuits. Keep exposed DC connector contacts away from metal objects and other conductive surfaces.
4. Do not exceed current ratings. Check the vehicle socket, fuse, output cable, and connector limitations.
5. Do not connect two energized power sources together. The adapter is not a battery isolator or automatic charging controller.
Can This Adapter Be Used to Charge a Car Battery?
The BX-CR15D has a direct DC barrel connection to the vehicle cigarette lighter plug. However, this does not make it a dedicated automotive battery charger.
Charging a vehicle battery through its cigarette lighter socket requires confirmation that the socket remains electrically connected to the battery, the circuit supports reverse power flow, and the charging source provides the correct voltage, current limiting, and battery charging protection.
For vehicle battery charging, use a properly rated automotive battery charger or approved charging connection. Do not assume that a standard cigarette lighter socket supports reverse charging.
Frequently Asked Questions
Does the BX-CR15D convert 24V to 12V?
No. The DC barrel output passes through the input voltage. The USB output separately converts the input to 5V DC.
Can I use this adapter in a 24V truck?
The specified input range is 10V–24V DC. Verify the actual socket voltage, particularly while the engine is running, because some nominal 24V vehicle systems exceed 24V during charging.
Can I use both output ports at the same time?
The adapter provides both a DC barrel output and a USB output. When using both, keep the total load within the adapter, vehicle socket, and circuit ratings.
Does the USB port support fast charging?
It provides standard 5V USB charging at up to 2.4A. It is not advertised as supporting USB-C PD or other higher-voltage fast-charging protocols.
Does the adapter include a DC output cable?
Yes. A 12-inch cable with 5.5 x 2.5mm male connectors is included with the standard package.
Will the adapter work when the vehicle engine is turned off?
That depends on the vehicle. Some cigarette lighter sockets remain powered with the engine off, while others require the ignition to be in the accessory or on position.
Can this adapter power a laptop computer?
Only if the laptop accepts the supplied DC voltage and the correct connector, polarity, and power requirements are satisfied. Many laptops require a different voltage or special power identification circuitry.
