322Wh High Capacity Rechargeable Battery with Multi-Voltage DC Converter
BiXPower MP330DC – Portable DC Power for Laptops, Electronics and Other DC Devices
The BiXPower MP330DC combines a high-capacity
322Wh rechargeable lithium-ion battery with a
versatile 90W DC-to-DC power converter.
It provides dependable portable DC power for compatible laptops,
electronic equipment, communication devices and other
DC-powered applications.
The included DD90X converter allows you to select different
constant output voltages, making this battery system a
flexible alternative to carrying several different
DC power supplies.
Key Features and Benefits
- 322Wh high energy capacity: Extended portable power for compatible electronic equipment.
- Six selectable DC output voltages: 12V, 15V, 16V, 18.5V, 19.5V and 24V through the included DD90X converter.
- Up to 90W DC output: Supports compatible devices within the converter's voltage and power ratings.
- 5V USB output: Additional USB power for compatible small electronics.
- 12 interchangeable connector tips: More flexibility when connecting devices with different DC input connectors.
- Portable design: Battery weighs approximately 4.1 lb (1.86 kg).
- Rechargeable: Includes an AC charger compatible with 100–240V AC power sources.
- Built-in battery protection: Protection functions include overcharge, over-discharge, overcurrent and temperature protection.
- One-year limited warranty: Covers qualifying manufacturing and quality defects.
322Wh High Capacity Portable Battery
With a nominal capacity of 12.8Ah at 25.2V,
the MP330DC stores approximately 322 watt-hours
of energy.
Unlike a conventional AC power bank that requires a DC-to-AC
inverter and then an AC-to-DC adapter, this system can provide
DC power directly to compatible devices. This may help reduce
unnecessary power conversion losses.
Actual operating time depends on device power consumption,
selected voltage, converter efficiency, battery condition
and operating conditions.
Compact Size and Portable Design
Battery dimensions: approximately 6.8 × 4.3 × 3 inches.
Two Ways to Power Your Devices
Option 1: Use the Battery Directly
The MP330DC battery provides a direct DC output with a nominal
voltage of approximately 25.2V.
Because the battery output is not constant voltage,
its voltage changes with the battery's state of charge:
- Fully charged: approximately 29.5V
- Typical operating range: approximately 24–26V
- Low battery cutoff: approximately 20V
Important: Direct battery output is suitable
only for devices designed to accept the full
approximately 20–30V DC input range.
Do not connect devices that require a tightly controlled
12V, 19V or 24V supply directly to the battery unless
their input specifications permit this voltage range.
Typical battery output voltage changes during discharge.
Option 2: Use the Included DD90X DC Converter
For devices requiring a specific constant DC voltage,
connect the battery to the included
BiXPower DD90X DC-to-DC converter.
The converter transforms the battery's variable voltage
into a selected constant output voltage.
Select the Output Voltage You Need
The DD90X provides these selectable DC output voltages:
- 12V DC
- 15V DC
- 16V DC
- 18.5V DC
- 19.5V DC
- 24V DC
Simply select the required output voltage before connecting
your equipment. Always confirm the correct voltage,
connector dimensions, polarity and power requirements.
Compatibility reminder: The DD90X has a
maximum output rating of 90W. It is not suitable for devices
that require more than its rated output power.
DD90X Converter Design and Connections
Additional 5V USB Power
The DD90X also features a 5V USB output for compatible
USB-powered electronics. This provides an additional
power connection without requiring a separate USB battery.
The USB port is a standard 5V output. USB-C Power Delivery
and fast-charging capabilities are not specified for this converter.
12 Interchangeable DC Connector Tips
The included connector tip kit helps the MP330DC connect
to a wider variety of compatible electronic devices.
The standard DD90X output connector is a
5.5mm outside diameter × 2.5mm inside diameter
DC barrel connector.
Interchangeable tips can be attached to change the physical
connector size when necessary.
Important: A physically fitting connector
does not guarantee electrical compatibility. Verify
the voltage, polarity, current rating and connector
configuration before connecting any equipment.
How to Charge the MP330DC Battery
The MP330DC package includes a dedicated AC battery charger
designed for use with 100–240V AC power sources.
- Turn off or disconnect the connected equipment.
- Connect the supplied charger to the battery charging port.
- Plug the charger into a compatible AC outlet.
- Follow the charger's indicator to determine when charging is complete.
- Disconnect the charger when charging is finished.
Charge the battery only with a compatible charger
and within the specified 0°C to 45°C charging
temperature range.
How to Connect the DD90X Converter
- Check your device's required DC input voltage and power.
- Choose the correct output voltage on the DD90X converter.
- Connect the battery output cable to the DD90X input connector.
- Choose the correct connector tip for your device, if needed.
- Connect the DD90X output to your device.
- Turn on the battery and verify normal device operation.

Frequently Asked Questions
Can I use this battery to power a 12V device?
Yes, provided the device is compatible with the DD90X
12V output, connector, polarity and maximum power rating.
Use the included converter rather than the battery's
direct variable-voltage output.
Can I power a laptop with the MP330DC?
Many laptops use DC power inputs such as 19V or 19.5V.
The DD90X provides a 19.5V setting, but compatibility
depends on the laptop's required voltage, connector,
power rating and any manufacturer-specific power
identification requirements.
Does the battery provide constant 24V output?
The battery itself provides variable DC voltage.
To obtain constant 24V DC output, connect the
included DD90X converter and select its 24V setting.
How long will the battery run my equipment?
Operating time depends primarily on device power
consumption. As an illustration, a 40W device
could run for approximately 7 hours when assuming
90% of the battery's rated energy is usable and
the converter operates at 95% efficiency.
Actual runtime may be shorter or longer.
Can I take this battery on an airplane?
The MP330DC has a rated energy capacity of approximately
322Wh, which exceeds the usual 160Wh maximum for
passenger-carried lithium-ion spare batteries.
It should not be considered suitable for ordinary
passenger airline carry-on or checked baggage.
Does the package include a battery charger?
Yes. The standard package includes a compatible
AC battery charger.
Are connector tips included?
Yes. The MP330DC combo package includes 12 interchangeable
DC connector tips. Connector compatibility should
always be verified before use.
