BiXPower CP300-UC100PD – 300Wh Rechargeable USB-C Laptop Battery with Up to 100W Power Delivery
The BiXPower CP300-UC100PD is a high-capacity portable power system combining a 300Wh rechargeable battery with a dedicated USB-C Power Delivery (PD) DC-to-DC converter. It provides convenient USB-C charging power for compatible laptop computers, tablets and other USB-C devices.
The included converter accepts the battery's DC power and negotiates an appropriate USB-C output voltage with a compatible connected device. Supported voltage levels include 5V, 9V, 12V, 15V and 20V, with a maximum rated output of 100W at 20V/5A.
Unlike a small USB power bank, this package provides a substantial 300 watt-hours of energy for applications where longer operating time is important. The included AC charger allows the battery to be recharged from a standard household electrical outlet.

300Wh High-Capacity Rechargeable Battery
The included BiXPower BX2494-series battery stores 300Wh of nominal energy. It is designed to supply portable DC power through its output connection to the included USB-C converter.
Battery dimensions and major controls.
The battery measures approximately 268 × 150 × 56mm (10.6 × 6 × 2.2 inches) and weighs approximately 2.2kg (5 lb).
The battery includes an output power switch, LED charge-level indicators, a dedicated charging port and a DC output cable for connecting compatible equipment.
Mountable Battery Design
Four mounting holes on the underside make it possible to secure the battery holder to a suitable supporting surface, subject to the installation requirements.
Secure the battery against vibration, movement, impact and moisture when installing it in equipment or a portable workstation.
USB-C Power Delivery Converter – Up to 100W
The included BiXPower USB-C PD converter changes the battery's variable DC output into a USB-C Power Delivery output suitable for compatible devices.
It supports multiple output voltage profiles and allows the connected USB-C PD device to request a suitable supported voltage and current.

USB-C Output Voltage Profiles
| USB-C PD Voltage | Typical Application |
|---|
| 5V | Compatible USB-C phones, accessories and electronics |
| 9V | Compatible devices requesting 9V USB-C PD |
| 12V | Compatible USB-C PD devices requiring 12V |
| 15V | Compatible tablets and portable electronics |
| 20V | Compatible USB-C laptops and other higher-power devices |
The maximum rated converter output is 100W at 20V/5A. Actual output depends on the connected device, its requested PD profile, the cable and the available input power.
USB-C Compatibility: A USB-C connector alone does not guarantee that a device supports USB Power Delivery charging. The device must accept one of the converter's supported PD profiles. For power levels above 60W, the complete USB-C cable assembly must also support the required current.
Converter Input and Output Connections
The converter accepts 10–32V DC input through a 5.5 × 2.5mm female barrel connector. Its input lead is approximately 200mm (8 inches) long.
The attached USB-C output cable is approximately 1000mm (40 inches) long.
The converter measures approximately 78 × 36 × 24mm and weighs approximately 180g.
Its compact metal housing helps make it convenient for portable use. The converter may become warm during high-power operation; keep it ventilated and do not cover it while in use.
How USB-C Power Delivery Works
USB Power Delivery (USB PD) is a charging protocol that allows a compatible power source and connected device to communicate and agree on a supported voltage and current.
For example, a compatible laptop may request 20V, while a smaller USB-C device may request 5V or 9V. The converter supplies the negotiated profile rather than applying the battery's raw voltage directly to the USB-C connector.
This flexibility allows one portable power system to serve different compatible USB-C devices without manually changing the output voltage.
Power Limit: The converter does not create energy. A 100W USB-C output requires more than 100W from the battery after accounting for conversion losses. Actual output and runtime depend on battery voltage, battery condition and converter efficiency.
How to Charge the Battery
The package includes a compatible AC charger that accepts 100–240V AC input.
To charge the battery, connect the charger to the battery's designated charging port and plug it into a suitable AC outlet.
- Turn off the battery and disconnect the powered device when practical.
- Connect the included charger to the designated charging port.
- Plug the charger into a compatible AC outlet.
- Allow charging to complete according to the charger and battery indicators.
- Disconnect the charger after charging is complete.
Charging Safety: Use the supplied charger or a BiXPower-approved compatible replacement. The USB-C converter is an output device, not a battery charger. Do not attempt to recharge the battery through the USB-C output cable.
Understanding the Battery's DC Voltage
The rechargeable battery has a nominal voltage of approximately 25V DC, but its raw output varies from approximately 29.5V when fully charged down to approximately 20V near discharge cutoff.
During much of the discharge cycle, the battery voltage is typically around 24–26V.
The USB-C converter is designed to accept the battery's variable voltage and generate the appropriate negotiated USB-C PD output.
Important: The battery's raw DC output is not a regulated 20V laptop output. Connect USB-C devices through the included USB-C PD converter, not directly to the battery's output connector.
How to Connect the Battery to the USB-C Converter
Using the included components is straightforward:
- Charge the battery with its AC charger.
- Connect the battery's DC output plug to the converter's female DC input connector.
- Connect the converter's USB-C output to a compatible USB-C PD device.
- Turn on the battery's output power switch.
- The converter and connected device negotiate a supported USB-C PD voltage and current.
Connect the battery output to the USB-C converter input.
Confirm that the device supports USB-C PD input and that its power requirement does not exceed the converter's capabilities.
Estimated Battery Runtime
The battery stores 300Wh of nominal energy. Actual runtime depends on device consumption, conversion losses, temperature and battery condition.
The examples below use an illustrative 85% usable-energy assumption, equivalent to approximately 255Wh delivered to the connected device.
| Average Device Power | Estimated Runtime* |
|---|
| 10W | 25.5 hours |
| 20W | 12.8 hours |
| 30W | 8.5 hours |
| 45W | 5.7 hours |
| 60W | 4.3 hours |
| 75W | 3.4 hours |
| 100W | 2.6 hours |
*Illustrative estimates only. They assume 300Wh × 85% = 255Wh usable output energy. Actual results vary, especially when laptop power consumption changes during use.
Typical Applications
The CP300-UC100PD is designed for compatible devices that accept USB-C Power Delivery charging.
- Compatible USB-C MacBook laptop computers
- Compatible Windows laptops with USB-C PD charging input
- USB-C tablets and portable computers
- Compatible USB-C mobile phones
- Portable electronic instruments supporting USB-C PD
- USB-C accessories and other compatible electronics
- Field work and portable computing away from AC outlets
Not all USB-C laptops can be powered at their maximum operating demand by a 100W source. Some high-performance laptops require more power, proprietary charging, or manufacturer-specific compatibility.
