within its normal voltage range
while the connected CPAP machine
receives regulated power.
The system includes three important
power components:
-
BX2499 Battery:
Stores 322Wh of rechargeable energy.
-
12V DC Converter:
Converts the battery's variable
output voltage to regulated 12V DC.
-
DreamStation Connector:
Connects the regulated output
to compatible CPAP machines.
Compatible DreamStation
CPAP and BiPAP Machines
The CP330 is designed for selected
Philips Respironics DreamStation
machines requiring 12V DC input,
including:
- DreamStation CPAP
- DreamStation Pro CPAP
- DreamStation Auto CPAP
- DreamStation BiPAP Pro
- DreamStation BiPAP Auto
Compatibility:
This package is intended for
compatible original DreamStation
models requiring 12V DC power.
Confirm your machine model,
input voltage, power requirements,
and connector before ordering.
DreamStation 2 compatibility
is not established by this listing.
High-Capacity 322Wh
Rechargeable Battery
BX2499 rechargeable battery
with integrated carrying handle.
The BX2499 is a compact,
high-capacity lithium-ion battery
designed for portable DC power
applications.
Its approximately 322Wh capacity
provides substantially more stored
energy than many small travel
power banks. The integrated handle
makes it easier to carry and
position the battery.

Compact High-Efficiency
12V DC Power Converter
Compact converter regulates
battery power to 12V DC.
The included BiXPower DC-to-DC
converter accepts a wide
10–30V DC input range and
produces regulated 12V DC output.
This converter is particularly
important because the BX2499
battery voltage changes as the
battery discharges. The converter
maintains a stable output voltage
for compatible CPAP equipment.

How Long Will the CP330
Power a CPAP Machine?
Actual runtime depends on the
machine's average power consumption,
therapy settings, humidifier use,
heated tubing, battery condition,
and conversion losses.
The following estimates assume
322Wh nominal battery capacity
and an illustrative 90% overall
usable-energy factor.
| Average CPAP Power |
Estimated Runtime |
| 10W | 29 hours |
| 15W | 19.3 hours |
| 20W | 14.5 hours |
| 30W | 9.7 hours |
| 40W | 7.2 hours |
| 50W | 5.8 hours |
| 60W | 4.8 hours |
These are calculated examples,
not guaranteed operating times.
The 90% factor is an assumption
for illustration, not a verified
system efficiency measurement.
Actual results may vary.
How to Extend CPAP Battery Runtime
-
Turn off heated humidification
when appropriate for your treatment.
-
Disable heated tubing if your
therapy setup permits.
-
Use your prescribed pressure settings.
-
Fully charge the battery before use.
-
Test your complete CPAP configuration
before depending on battery power
overnight.
How to Charge the CP330 Battery

the included AC charger.
-
Connect the included AC charger
to the battery charging port.
-
Plug the charger into a compatible
100–240V AC wall outlet.
-
Allow the battery to charge according
to the charger instructions.
-
Disconnect the charger when
charging is complete.
How to Connect the CP330
to a DreamStation Machine
Battery, converter, and special
DreamStation connector arrangement.
-
Fully charge the BX2499 battery.
-
Connect the DC converter input
to the battery output cable.
-
Connect the special DreamStation
power connector to the converter.
-
Connect the special connector
to the compatible CPAP machine.
-
Turn on the battery output.

Electrical Safety:
The BX2499 battery's direct output
is approximately 20–29.5V DC.
Do not connect this unregulated
output directly to a 12V
DreamStation machine.
Always use the included
regulated 12V converter.
Understanding Battery
Output Voltage
Direct battery output must pass
through the 12V converter.
The BX2499 battery has a nominal
voltage of approximately 25V.
Its output may reach approximately
29.5V when fully charged and
decrease toward 20V as it discharges.
This variation is normal for
the battery. The included converter
regulates the output to 12V DC
for compatible DreamStation machines.

automatic UPS system.
Can I use heated humidification?
Only if the complete CPAP
configuration stays within the
converter's 12V/6A output rating.
Heated humidification may
substantially reduce runtime.
Check the machine's power
requirements before use.
Can I use this battery
with DreamStation 2?
Compatibility with DreamStation 2
has not been established for
this package. Confirm model-specific
power and connector requirements.
