BiXPower 90W USB-C PD to 24V DC Power Converter
Convert USB-C Power Delivery power into stable, regulated 24V DC power with this compact, lightweight, high-efficiency DC-to-DC power converter.
USB-C power banks, portable batteries, and USB-C PD chargers are convenient power sources for many electronic devices. However, standard USB-C PD power sources typically provide voltage levels such as 5V, 9V, 12V, 15V, and 20V, rather than a fixed 24V output.
The BiXPower DD90M-USBC-24V solves this problem by using a special USB-C PD input cable and a high-efficiency DC voltage converter to provide regulated 24V DC output for compatible electronic equipment.
Its miniature size and lightweight design make it an excellent choice for portable 24V power applications, battery-powered equipment, mobile electronics, and other devices requiring a stable 24V DC power supply.

How to Get 24V DC Power from USB-C
Most conventional USB-C PD power sources do not offer a fixed 24V output. Many USB-C PD power banks and chargers provide up to 20V DC through their standard fixed-voltage profiles.
The BiXPower converter uses a two-stage process:
- USB-C PD voltage negotiation: The included special USB-C input cable requests 20V DC from a compatible USB-C PD power source.
- DC-to-DC voltage conversion: The converter transforms the incoming DC power into a stable, regulated 24V DC output.
This allows a compatible USB-C PD battery or power adapter to supply power to equipment that requires 24V DC rather than the standard USB-C PD output voltages.
USB-C PD Input Requirements
The included special USB-C cable is designed to obtain 20V DC power from a USB-C Power Delivery source that supports the 20V PD output profile.
Important: A USB-C connector alone does not guarantee compatibility. The USB-C power source must support USB Power Delivery and provide the required 20V output.
USB-C ports limited to 5V, 9V, or 12V may not operate properly with the included 20V PD input cable.
Power Rating and Compatibility
For high-power applications, choose a USB-C PD source capable of providing sufficient power at 20V. A 20V/5A USB-C PD source provides up to 100W input power. Because some energy is lost during conversion, the available 24V output power is lower than the USB-C input power.
The converter's maximum usable output depends on the PD source, cable capabilities, conversion efficiency, operating conditions, and connected equipment. Do not assume that every USB-C PD charger or battery can provide the full rated output.
DC Converter Input Connector
The DC converter uses a 5.5 x 2.5mm female DC input jack with positive-center polarity.
Special USB-C PD Input Cable
The included USB-C PD input cable has a USB Type-C connector on one end and a DC barrel connector on the other end.
When connected to a compatible USB-C PD power source, the cable negotiates a 20V DC output and delivers that power to the converter's DC input port.
Connect the USB-C end to your compatible USB-C PD battery or charger, then connect the DC barrel plug to the converter input jack.
Compact Size and High-Efficiency Design
The BiXPower DD90M converter is designed for applications where installation space, weight, and energy efficiency are important.
- Small dimensions: 2.5 x 1.9 x 0.7 inches (approximately 63.5 x 48.9 x 16.9mm)
- Lightweight: Approximately 2.54 oz (72g), converter only
- High efficiency: Up to 96% conversion efficiency under suitable operating conditions
- Portable design: Convenient for mobile equipment and compact installations
Why High Efficiency Matters
A DC-to-DC converter consumes some energy during voltage conversion. Higher efficiency means less energy is wasted as heat and more energy is delivered to the connected device.
For example, when supplying a 90W load:
| Efficiency |
Input Power |
Power Loss |
| 80% |
112.5W |
22.5W |
| 85% |
105.9W |
15.9W |
| 96% |
93.75W |
3.75W |
At 96% efficiency, delivering 90W of output power would require approximately 93.75W of input power, assuming the converter achieves that efficiency at the operating load.
This can be particularly valuable when powering equipment from portable batteries, where minimizing energy losses helps extend battery operating time.
Converter Input and Output Connections
24V DC Output Cable
The included dedicated 24V output cable provides the regulated DC output for compatible 24V devices.
The standard DC output connector is a 5.5 x 2.5mm male barrel connector. Check your device's connector dimensions, polarity, voltage, and power requirements before connecting.
Additional Features and Protection
- Regulated DC output: Provides stable output voltage for compatible electronic devices.
- Additional USB power output: Built-in USB output supports compatible USB-powered devices.
- Short-circuit protection: Helps protect the converter during output short-circuit conditions.
- Overcurrent protection: Helps limit excessive output current.
- Overvoltage protection: Helps protect against abnormal voltage conditions.
- Overtemperature protection: Helps protect the converter against excessive operating temperatures.
- Protective housing: Designed with protective enclosure materials for electrical equipment applications.
The USB output and main DC output share the available input power and converter capacity. When using multiple outputs, ensure the combined load remains within the available power budget.

Note: The converter hardware and the complete USB-C PD configuration have different practical power limits. The main DC output is rated up to 90W in this listing. At 24V, 90W corresponds to 3.75A. Actual available power depends on input source capability, efficiency, temperature, and any simultaneous USB load.
How to Connect the 24V Output Cable
The output cable uses a special connector at the converter end. Proper connector orientation is important.
- Locate the end of the output cable with the special connector.
- Identify the small flat surface containing three holes.
- Orient the connector so that the flat surface faces upward toward the top of the converter.
- Carefully insert the connector into the converter output port.
- Connect the 5.5 x 2.5mm male barrel connector to a compatible 24V DC device.
Do not force the connector into the converter. Verify correct orientation before insertion.

Frequently Asked Questions
Can a USB-C port provide 24V DC power directly?
Standard USB-C PD fixed-voltage profiles generally do not include 24V DC. This converter obtains a compatible input voltage, typically 20V, and converts it to regulated 24V DC. Some newer USB-C PD implementations support additional voltage profiles, but compatibility with this product depends on the included 20V PD input cable.
Will this converter work with any USB-C power bank?
No. The USB-C power bank must support USB Power Delivery and provide a compatible 20V output. It must also have enough output power for the connected 24V equipment.
Can I use a USB-C laptop charger as the power source?
Yes, a compatible USB-C PD laptop charger may be used if it supports the required 20V PD output and supplies sufficient power for the load.
Does this converter increase the available power?
No. The converter increases the voltage from the negotiated input voltage to 24V, but it cannot create additional electrical power. The output power is limited by the input power and conversion losses.
Can this converter provide 12V, 16V, or 19V?
Yes. The converter supports these additional regulated output voltages when used with the appropriate optional output cable. The included cable provides 24V DC.
Can I use a different DC connector?
Yes. The included output cable has a standard 5.5 x 2.5mm male connector. Compatible BiXPower C-Series connector tips can adapt it to other connector sizes.
Can I charge a 24V lithium-ion battery with this converter?
This product is a regulated DC power converter, not a dedicated lithium-ion battery charger. Do not use it to directly charge a lithium-ion battery unless the battery has a compatible built-in charging system designed to accept a regulated 24V DC input.
