3 Ways to Connect Input Power
Stable 19V Power from a Wide Range of DC Sources
The
BiXPower BX-DD90M2-19V is a remarkably compact and
high-efficiency DC-to-DC converter designed to convert a wide
10V–30V DC input range into a stable, regulated
19V DC output.
Its wide input range allows one converter to work with many different
DC power sources, including
12V batteries, 24V batteries,
vehicle electrical systems, solar power systems and portable battery
systems
.
The converter is suitable for powering many compatible 19V devices,
including laptops, monitors, embedded systems, LED displays,
communication equipment and other electronics requiring regulated
19V DC power.

- Stable Regulated 19V Output — designed to provide consistent 19V DC power as input voltage changes.
- Up to 90W Output — 19V output supports up to approximately 4.75A.
- Up to 96% Conversion Efficiency — minimizes power loss, especially important when operating from batteries.
- Super Compact — only approximately 2.5 × 1.9 × 0.7 inches.
- Ultra-Lightweight — only approximately 2.54 oz. (72g).
- 3 Ways to Connect Input Power — direct barrel connection, included input cable, or bare-wire connection.
- USB Fast-Charging Port — provides additional USB power for compatible mobile devices.
- Interchangeable Output Cables — optional cables allow the same converter to provide 12V, 16V or 24V output.
- Optional Connector Tips — adapt the standard output connector to many different DC connector sizes.
- Built-In Protection — short-circuit, over-current, over-voltage and over-temperature protection.
Super Small — Only 72g
One of the biggest advantages of the BX-DD90M2 is its exceptionally
small size. The converter measures only approximately
2.5 × 1.9 × 0.7 inches (63.5 × 48.9 × 16.9mm).
It weighs only about
2.54 oz. (72g), making it easy
to carry with a portable battery, laptop or mobile power system.
It can also be installed in tight spaces where a conventional DC
power converter would be too large.
espite its tiny size, this converter can provide up to approximately
90W of regulated 19V DC power.
Up to 96% Efficiency — Get More Runtime from Your Battery
High efficiency is especially important when a converter is powered
from a battery. Every watt consumed by the converter itself is energy
that is not available to your equipment.
The BX-DD90M2 is designed for conversion efficiency of
up to 96%, meaning very little input energy is wasted
during voltage conversion.
Why High Efficiency Matters
As an example, a converter operating at 85% efficiency would require
approximately
106W from the battery to deliver 90W
to the connected device.
At approximately 96% efficiency, only about
94W of input power is needed to deliver approximately 90W.
That difference can mean less wasted battery energy, less unnecessary
heat and potentially longer operating time from the same battery.
Wide 10V–30V DC Input Range
The BX-DD90M2 is not limited to a single fixed input voltage.
It accepts a broad
10V–30V DC input range.
This allows it to operate from many different power sources, including:
- 12V battery systems
- 24V battery systems
- Lithium-ion battery packs
- Lead-acid batteries
- Vehicle electrical systems
- Solar power systems
- Portable DC power supplies
- Other compatible 10V–30V DC sources
This wide input range is particularly useful with batteries because
battery voltage naturally changes as the battery charges and discharges.
The converter regulates the changing input voltage into a stable
19V DC output.
Flexible 5.5 × 2.5mm DC Input
The converter has a built-in
5.5 × 2.5mm female DC input jack.
The input polarity is
center positive.
A 16AWG input cable is included with the converter,
giving you several convenient ways to connect it to your DC power source.
3 Ways to Connect to Input Power
Different batteries and DC systems use different types of power
connections. The BX-DD90M2 gives you three practical ways to connect
the converter to your power source.
1. Use the Included 16AWG Input Cable
The package includes a 16AWG input cable with
5.5 × 2.5mm male connectors.
Use this cable when your battery or DC power source has a compatible
5.5 × 2.5mm female output jack.
2. Direct Bare-Wire Connection
For a custom or hardwired installation, you may cut off one connector
from the included input cable and use the two wires to connect directly
to your DC power source.
This method is useful for batteries, terminal blocks, vehicle wiring,
solar systems and other installations without a matching barrel connector.
3. Connect Directly to the Converter Input Port
If your DC power source already has a
5.5 × 2.5mm male connector, simply plug it directly into the converter's 5.5 × 2.5mm female input port.
No additional input cable is required.
Important: Always verify input polarity before applying
power. Incorrect polarity may damage the converter or connected equipment.
19V Main Output + USB Fast-Charging Output
The BX-DD90M2 provides two useful power outputs:
a main DC output for your 19V device and a separate USB output for
compatible USB-powered electronics.
Constant 19V Main Output
With the included 19V output cable, the converter provides
regulated 19V DC output up to approximately 4.75A,
for a maximum output of approximately 90W.
USB Fast-Charging Output
The built-in USB port can also power or charge compatible smartphones,
tablets and other USB devices.
USB output supports up to:
5V/3A, 9V/2A or 12V/1.5A, depending on the connected
device and charging protocol.

- 1 × BX-DD90M2 Mini DC-to-DC Power Converter
- 1 × 19V Output Cable
- 1 × 16AWG Input Cable
How to Connect the 19V Output Cable
The special output cable determines the converter's main output voltage.
For this model, the included cable provides
19V DC output.
One end of the output cable has a small flat surface and three holes.
Insert this end into the converter's output port with the
flat surface facing upward toward the top of the converter.
Important: Make sure the output cable is oriented
correctly before inserting it into the converter. Do not force the
connector into the output port.
Optional Output Cables — One Converter, Multiple Voltages
A unique feature of the DD90M2 design is that the
special output cable controls the main output voltage.
This package includes the
19V output cable, but optional
output cables can allow the same converter to provide other output
voltages, including:
- 12V DC
- 16V DC
- 19V DC — included with this package
- 24V DC
This makes the converter more versatile because the converter itself
does not need to be replaced when a different supported output voltage
is required — simply use the appropriate output cable.
Optional Connector Tips for More Devices
The output end of the 19V cable uses a standard
5.5 × 2.5mm male barrel connector.
If your device uses another connector size, an optional
BiXPower C-Series connector tip can be plugged over
the standard connector to adapt it to many other DC connector sizes.
This allows the same converter and 19V output cable to work with a
much wider variety of compatible laptops and electronic devices.
Included 16AWG Input Cable
The included input power cable has
5.5 × 2.5mm male connectors and is approximately
14 inches long.
The converter's input port is a
5.5 × 2.5mm female jack with center-positive polarity.

connection.
Add the built-in USB fast-charging port, interchangeable output-voltage
cables and optional connector tips, and the result is a
compact, efficient and highly versatile DC power solution
for portable, mobile, vehicle, solar, industrial and off-grid applications.
Please verify compatibility before use:
• Input power must remain within 10V–30V DC.
• Confirm correct input polarity before applying power.
• The included output cable provides 19V DC.
• Confirm your device requires 19V and does not exceed the converter's rated output.
• Verify connector size and polarity before connecting your device.
Important Information for High Output Power Use:
This converter accepts a wide input voltage range of 10V–30V DC, providing flexibility for use with a variety of DC power sources. For high-power applications that require high output power from the converter, it is recommended to use
a higher-voltage input power source whenever possible. A lower input voltage requires higher input current to produce the same output power.
When using a lower-voltage power source, such as 12V, high-power output may require a very high input current, which can cause the input connector and connection point to become hot. Please monitor the input connection during high-power operation.
If the input connector becomes excessively hot, stop using the device immediately.
