Need USB-C Laptop Charging Instead?
Many newer laptops use
USB Type-C Power Delivery (USB-C PD) for charging instead of traditional 19V DC barrel connectors.
If your laptop charges through a USB-C PD port, consider our
BiXPower 100W USB-C PD Vehicle Laptop Charger (CR1224-USBC-PD100)
.
This alternative adapter accepts the same wide
9V–32V DC input range, making it suitable for compatible 12V cars, 16V Tesla vehicles, 24V trucks, and RVs.
It provides intelligent USB-C Power Delivery with selectable output profiles of
5V, 9V, 12V, 15V, and 20V, delivering up to 100W (20V/5A) to compatible devices.

Can a 19V Laptop Charger Power 18.5V, 19.5V, or 20V Laptops?
Although the BiXPower CR1224T19-120W-KIT provides a
regulated 19V DC output, some laptop computers and electronic devices designed for slightly different DC input voltages may also operate with a 19V power source.
For example, certain laptop models specify 18.5V, 19V, 19.5V, or 20V DC input. Depending on their internal power-management design and voltage tolerance, some of these devices may accept a regulated 19V supply.
The output voltage remains 19V DC.
This adapter does not automatically adjust its voltage to match the connected device.
Voltage Compatibility Reference
| Device Rated Voltage |
Using 19V Output |
| 18V DC |
Requires confirmation of device voltage tolerance. |
| 18.5V DC |

| 21V DC |
Use only when 19V operation is explicitly supported or verified. |
Compatibility with HP, Dell, and Other Laptops
Some HP, Dell, and other laptop computers use nominal power adapter voltages such as 18.5V, 19V, 19.5V, or 20V. Certain models may operate from this BiXPower regulated 19V adapter when their voltage tolerance, connector type, polarity, and power requirements are compatible.
The converter supplies up to 120W (19V, 6.3A maximum). The connected laptop must not exceed this output rating.
Important Compatibility Notice:
Always check your laptop manufacturer's input voltage tolerance before using a different nominal voltage. Some HP and Dell laptops require special power-adapter identification signals and may not charge properly with a standard DC connector, even when the voltage and connector dimensions appear correct. Never rely on voltage similarity alone to establish compatibility.

12 Interchangeable Laptop Power Connector Tips Included
Laptop manufacturers use different power connector sizes. This kit includes 12 interchangeable connector tips to help the converter work with a variety of compatible 19V laptop computers.
The adapter's standard 5.5 × 2.5mm male DC output connector can be used directly when compatible, or fitted with an included connector tip to match another supported connector size.
Included 12-piece interchangeable laptop connector kit.
Simply attach the appropriate connector tip to the converter's output plug.
How to Choose the Correct Connector
- Check your laptop's original AC adapter label for the required DC output voltage and current.
- Confirm that your laptop requires 19V DC and does not exceed the converter's 120W maximum rating.
- Identify the correct connector size and polarity for your laptop.
- Select a compatible connector tip from the included set.
- Connect the tip securely to the adapter's output plug before connecting it to your laptop.
Compatibility Warning: Matching the physical connector size is not sufficient. Verify voltage, polarity, current requirements, and any manufacturer-specific power identification features. Some laptops require special identification circuitry and may not work with a standard barrel connector.

Ideal for Mobile Offices, Vehicle Travel & Field Equipment
- Business Travel: Power compatible laptops while working from a vehicle.
- Truck Drivers: Use compatible 19V laptop computers with 24V truck DC power outlets.
- Tesla Owners: Convert compatible 16V accessory outlet power to regulated 19V DC.
- RV & Camping: Operate supported laptops from compatible vehicle DC power systems.
- Field Technicians: Supply 19V DC power to compatible portable electronics and testing equipment.
- Mobile Workstations: Reduce reliance on AC inverters when a device can operate directly from regulated 19V DC.
Why use DC-to-DC conversion?
A traditional setup converts vehicle DC power to AC through an inverter, then converts AC back to DC through a laptop charger. This adapter provides the required 19V DC directly, avoiding those extra conversion stages. Actual efficiency depends on the equipment and operating conditions.
