BIXPOWER RECHARGEABLE BATTERY SYSTEM
Two 99Wh Rechargeable Batteries -
198Wh Combined Capacity with Constant 12V Output
The BiXPower BP90X2-12V is a
portable rechargeable lithium-ion battery package
featuring two independent 99Wh batteries, providing
a combined energy capacity of 198 watt-hours.
Each battery has a capacity below 100Wh, making
this battery system especially convenient for
airline travel, business trips, outdoor activities,
and portable electronic equipment.
Use each battery independently, or connect both
batteries through the included power split dongle
to provide a shared 12V power connection for
compatible equipment.

Why Choose the BP90X2-12V Battery System?
Two Batteries, 198Wh Total
Two separate 99Wh rechargeable batteries provide
a combined 198Wh energy capacity. Use one battery
while keeping the other available as a spare.
Convenient for Air Travel
Each battery is individually rated at 99Wh,
below the common 100Wh airline lithium-ion
battery limit. Carry-on and airline rules apply.
Constant 12V Power
The dedicated regulated 12V DC output provides
a stable voltage for compatible 12V electronic
devices, even as battery charge decreases.
Flexible Charging
Charge with the included AC charger or from
a compatible 12V-24V DC charging source.
An optional car charging cable is available.
Air Travel Friendly - Each Battery Under 100Wh
Many larger rechargeable batteries exceed 100Wh
and may require special airline approval.
The BP90X2-12V takes a different approach:
instead of one large battery, it includes
two separate 99Wh batteries.
This design provides 198Wh of total available
energy while keeping the individual battery
ratings below 100Wh.
Under common FAA and TSA rules, spare lithium-ion
batteries rated at 100Wh or less are generally
permitted in carry-on baggage, subject to airline
policies and applicable quantity restrictions.
Important Airline Travel Information:
Each BP90 battery is rated at 99Wh. Carry batteries
in cabin baggage, protect exposed terminals against
short circuits, and disconnect all external cables
during transport. Spare lithium batteries must not
be placed in checked baggage. Always confirm the
latest rules with your airline before traveling.
The two batteries are separate 99Wh units;
the combined 198Wh rating does not represent
a single battery.
Use Each Battery Independently
Each BP90-12V battery can power a compatible
electronic device independently. This is useful
when you need a spare battery, want to power
two separate devices, or prefer to carry only
one battery for shorter trips.
Use one BP90 battery with the DC power cable
Compact and portable battery design
Connect Two Batteries for Extended Runtime
The included Y25 power split dongle allows
two BP90 batteries to share a common power
output connection.
With both fully charged batteries, the system
provides a combined nominal energy capacity
of 198Wh. Actual usable energy and runtime
depend on the connected equipment, power
consumption, conversion losses, and operating
conditions.

Connection Note:
Connect only compatible BP90 batteries using
the specified BiXPower split cable.
Both batteries should be at similar charge
levels before connecting them together.
Do not use a generic Y-cable to combine
unrelated batteries.
Three Convenient Power Output Ports
Each BP90-12V battery includes three power
outputs for different portable electronic
applications.
BP90 battery input and output connections
Output I - 5V USB
Standard USB-A output rated at 5V, up to 2.1A.
Suitable for charging compatible smartphones,
USB accessories, and other 5V electronic devices.
USB charging cable is not included.
Output II - 9V to 12.6V DC
This output is connected to the battery cells
without constant voltage regulation.
Its nominal voltage is 11.1V and the voltage
varies from approximately 12.6V when fully
charged to 9V near discharge cutoff.
Connector: 3.5 x 1.35mm.
Maximum rated output current: 5A.
Output III - Constant 12V DC
The regulated output provides a stable 12V DC
voltage for compatible equipment requiring
constant 12V power.
Connector: 5.5 x 2.5mm DC barrel jack.
Confirm device voltage, polarity, connector
dimensions, and power requirements before use.
Easy and Flexible Battery Charging
The included AC charger operates from a
100V-240V AC power source, 50/60Hz, making
it convenient for use in different countries
with an appropriate AC plug adapter.
Each battery has a DC charging input that
accepts a compatible 12V-24V DC charging
source through a 5.5 x 2.1mm connector.
Charge One Battery
Charging a single BP90 battery
Charge Two Batteries with One Charger
Use the included 5.5 x 2.1mm charging
split dongle to connect the supplied
charger to both batteries.
Charging two BP90 batteries simultaneously
Typical charging time for one battery is
approximately 4-6 hours under specified
charging conditions. Charging two batteries
together may take longer.
An optional
CH160 car charging cable
may be used with a compatible vehicle
cigarette lighter power socket.

Frequently Asked Questions
Can I take these batteries on an airplane?
Each BP90 battery is rated at 99Wh,
below the common 100Wh limit for
lithium-ion batteries in carry-on baggage.
Carry the batteries separately with terminals
protected and follow airline regulations.
Is the battery capacity 99Wh or 198Wh?
Each battery has a capacity of 99Wh.
The package contains two batteries,
providing 198Wh of combined nominal
energy capacity.
Can I use just one battery?
Yes. Each battery operates independently
and has its own power output ports.
Can I connect both batteries together?
Yes. Use the included BiXPower Y25
power split dongle with compatible
BP90 batteries at similar charge levels.
Does the battery provide constant 12V?
Yes. Output III provides regulated
constant 12V DC. Output II provides
a variable 9V-12.6V DC output.
Can I charge both batteries together?
Yes. The package includes a charging
split dongle that allows the included
charger to charge both batteries.
Charging time may increase.
Can these batteries power a CPAP machine?
They may power compatible 12V CPAP
equipment if the machine's voltage,

are supported. Some CPAP machines
require special DC power adapters or
converters. Confirm compatibility before use.
How long will the batteries run my device?
Runtime depends on power consumption.
For example, a device drawing 20W
would have a theoretical runtime of
approximately 9.9 hours using the
combined 198Wh capacity. Actual runtime
will be shorter due to conversion losses
and battery operating conditions.
