Two 99Wh Batteries –
Convenient for Air Travel
Each Battery Is Below 100Wh
The BP90X2 package contains
two separate BP90 batteries,
each with a nominal capacity
of 99 watt-hours.
Under current U.S. FAA rules,
spare lithium-ion batteries
rated at 100Wh or less are
generally permitted in
carry-on baggage without
special airline approval,
subject to applicable restrictions.
Although the two batteries
provide 198Wh combined,
each battery is individually
rated at 99Wh.
This makes the package
particularly attractive for
CPAP users who want additional
runtime while traveling.
Airline Battery Safety Guidelines
-
Carry spare lithium-ion batteries
in carry-on baggage only.
-
Do not place spare batteries
in checked baggage.
-
Protect connectors against
accidental short circuits.
-
Keep each battery's capacity
label visible for inspection.
-
Check your airline's rules
on battery quantities and
international travel.
-
Do not travel with damaged
or recalled batteries.
For current requirements, visit
FAA Airline Passengers and Batteries
.
Important:
The two batteries are individually
below 100Wh, but airline acceptance
is subject to current regulations
and carrier policies. Do not
assume every airline will accept
all battery quantities or setups.
Flexible Operation –
Use One or Two Batteries
Option 1: Use One BP90 Battery
Each BP90 battery can independently
power a compatible 12V DreamStation
machine through the included
special power cable.
Simply connect the power cable
to regulated Port III on one
battery, then connect the
other end to the CPAP machine.
Single-battery connection.
Option 2: Connect Two Batteries
for Longer Runtime
Use the included BiXPower
Y25 split connector to connect
the regulated 12V output ports
of two compatible BP90 batteries.
This combines their available
energy for longer operation
without manually switching
between batteries.
Y25 power output split connector.

their regulated 12V output ports.
Connecting the CPAP Power Cable
After connecting the Y25 splitter
to both batteries, connect the
special DreamStation power cable
to the female output connector
of the Y25 splitter.
Dual-battery power connection.
Complete two-battery output setup.
Step-by-Step Dual-Battery Setup
-
Fully charge both BP90 batteries.
-
Confirm both batteries provide
regulated 12V from Port III.
-
Connect one male plug of the
Y25 splitter to Port III
of Battery 1.
-
Connect the second male plug
to Port III of Battery 2.
-
Connect the special DreamStation
power cable to the Y25
female output connector.
-
Connect the power cable
to the compatible CPAP machine.
-
Activate the battery outputs
and verify normal CPAP operation.
Important Parallel
Connection Safety:
Only use regulated Port III
on both batteries. Each battery
must independently support
the full connected load.
The Y25 connection is intended
to extend runtime, not increase
the permissible equipment
power demand beyond one
battery's output rating.
The batteries do not have
active load-balancing control.
One battery may discharge
faster than the other.
Three Convenient Power
Output Ports on Each Battery
BP90 battery output ports.
Port I – 5V USB Output
Provides 5V USB power
with up to 2.1A output current
for compatible mobile phones
and other USB devices.
USB charging cable is not included.
Port II – Variable DC Output
Provides a nominal DC output
of approximately 10.8–11.1V.
The voltage varies from
approximately 9V to 12.6V
depending on battery charge.
This output is not regulated
and should only be used
with compatible equipment.
Connector size: 3.5 × 1.35mm.
Maximum output current: 5A.
Port III – Regulated 12V Output
Port III provides regulated
12V DC output with a maximum
current of 5A, or 60W.
This is the designated output
for compatible DreamStation
CPAP machines and the Y25
dual-battery connection.
Important:
Use only regulated Port III
for the DreamStation CPAP
power connection. Do not use
the variable-voltage Port II.
How Long Can Two BP90
Batteries Power a CPAP Machine?
The combined nominal capacity
of two BP90 batteries is 198Wh.
Actual runtime depends on
machine pressure, humidifier,
heated tubing, and other
operating conditions.
The following estimates assume
an illustrative 90% usable-energy
factor, not a guaranteed
conversion efficiency.
| Average CPAP Power |
Estimated Runtime |
| 5W | 35.6 hours |
| 8W | 22.3 hours |
| 10W | 17.8 hours |
| 12W | 14.9 hours |
| 15W | 11.9 hours |
| 20W | 8.9 hours |
| 25W | 7.1 hours |
Under favorable low-power
conditions with heated
humidification turned off,
the BP90X2 may provide
approximately two nights
or longer of operation.
These figures are estimates.
Actual runtime may be shorter
or longer depending on the
CPAP machine and settings.
Tips to Maximize Runtime
-
Disable heated humidification
when appropriate for your therapy.
-
Turn off heated tubing
when practical.
-
Use your prescribed
pressure settings.
-
Fully charge both batteries
before overnight operation.
-
Test the complete setup
before relying on it for sleep.
Recharge Your BP90 Batteries

Frequently Asked Questions
Can I take two BP90
batteries on an airplane?
Each battery is individually
rated at 99Wh, which falls
within the standard FAA
100Wh category for spare
lithium-ion batteries.
Carry-on and airline-specific
rules still apply.
Are the two batteries
connected permanently?
No. Each BP90 battery can
operate independently.
The included Y25 splitter
allows both batteries to
be connected when longer
runtime is needed.
Will the BP90X2 work
with DreamStation machines?
It is designed for selected
original Philips Respironics
DreamStation CPAP and BiPAP
machines requiring 12V DC.
Confirm your machine's
requirements before ordering.
Can I charge both batteries
with one AC charger?
Yes. The included Y21 charging
splitter allows the supplied
charger to connect to both
batteries simultaneously.
Charging time may increase.
What is the difference
between Y21 and Y25?
The Y21 is used for charging
two batteries through their
charging input ports.
The Y25 is used to combine
their regulated 12V output
ports for extended runtime.
How long will two batteries
power my CPAP machine?
Runtime depends on machine
power consumption. Two BP90
batteries provide 198Wh of
combined nominal energy.
Use the runtime table above
for illustrative estimates.
Can I use the heated
humidifier with BP90X2?
The complete CPAP configuration
must remain within the regulated
12V/5A output rating of one
battery. Heated humidification
can significantly reduce runtime.
Can the Y25 splitter
increase output power?
No. The Y25 connection is
intended to extend runtime,
not to power equipment that
exceeds a single BP90 battery's
rated output capability.
Does the package include
a car charger?
Yes. A compatible 12V
vehicle charging cable
is included.
Does BP90X2 work
with DreamStation 2?
DreamStation 2 compatibility
is not established by this
product listing. Confirm
its electrical requirements
before ordering.
