    Product Features

    The C-100 Travel Battery Pack for CPAP Machines with 150W Modified Sine Wave Inverter is a combination of the C-100 Battery and 150W Inverter. This combination provides options to use the battery to power devices which require AC power, and also allows the battery to be charged from a DC source.


    • AC Power Output
    • Battery Charging from DC
    • Functional Carry Bag
    • Included Accessories

    AC Power Output

    With use of the included 150W inverter, the DC power provided from the C-100 battery will be inverted into AC power. The inverter features a standard AC outlet so that CPAP machines and other devices that are not DC compatible and require AC power can be used with the battery. Please verify the wattage requirements of the device being plugged in as some require higher than 150W. The following machines require AC power and can be used with the inverter connected to the battery:

    Use While on AC Power

    The C-100 Travel Battery for CPAP Machines is a movable, power source intended for short-term use. Because the battery has an input and output, the battery can be plugged into an AC power source to receive a charge while being plugged into a device to discharge. The C-100 battery will discharge its stored power to the device while simultaneously receiving a charge from the AC power source.

    The continuous charging and discharging occurring from the battery, will reduce the number of cycles remaining in the battery life. It is recommended only to set the battery in this configuration when a power outage is imminent, as this configuration will shorten the lifespan of the battery. If using a device that will draw a significant amount of battery charge, such as pairing a humidifier with a machine, it is recommended to have two battery cells to provide a longer run time.

    Battery Charging from DC

    The inverter inverts DC power to AC power, allowing for charging of the C-100 battery from a DC source. To do so, plug the cigarette-style cord from the inverter into a DC outlet, then plug the C-100 battery charger into the AC outlet on the inverter and then into the battery. The lights on the end of the C-100 battery indicate if the battery has completed charging or not.

    Please note the charge time from a completely drained battery is 4-5 hours, so it is not recommended to attempt fully charging the battery from a DC power source that could completely drain during the charging process.

    Functional Carry Bag

    The C-100 carry bag is designed for ease of use. There are two interior envelopes with Velcro closures to hold two C-100 battery cells inside the bag. On one end of the bag is a clear flap to quickly view charging status and charge level. The battery can be used and charged inside the bag. The included inverter can easily fit inside the bag to be taken along if needed.

    Included Accessories

    This C-100 battery kit includes all necessary components to charge the battery from an AC or DC source, and to use the battery as a DC source for compatible devices, or to be inverted into an AC source for AC only devices.

    Compatibility with AirSense and AirCurve 10 Machines

    Although the 150W inverter will provide an AC power outlet to plug the AirSense or AirCurve 10 power supply in to, it will provide a very low run time in this configuration. It is NOT RECOMMENDED to use the inverter to power these machines. Instead use the AirSense and AirCurve 10 24V Power Converter for C-100 Battery.

    Just need DC power, not AC power? The C-100 Travel Battery Pack for CPAP Machines is the same package without the added inverter.

      • 3 green LEDs = 50% - 85% Charge
      • 4 green LEDs = > 85% Charge

    Charging Instructions

    1. Connect the AC power cord to the power supply (charger).
    2. Plug the charger's output cable into the "DC In" port of the battery.
    3. Connect the charger to a AC outlet.
    4. When fully charged, the "Full Charged" indicator on the battery will light up green.
    5. Once fully charged, disconnect the charger from the battery and AC outlet.
    6. Estimate 4 to 5 hours to charge when battery is fully discharged.

    • International Charging: The charger can be used internationally in AC currents from 100V to 240V with appropriate plug adapters such as World Traveler Power Adapter Plugs.
    • Dual Battery Charging: The charger can be used to charge two batteries at once. Simply connect the DC Power Pigtail Cord to the output cable of the charger, then plug the pigtail cable into both batteries.
    • Charging from DC Source: Purchase the optional DC to DC Cable for C-100 Travel Battery Pack to charge the battery directly from a DC source using a cigarette lighter style outlet. Also, the C-100 battery may be charged using the included inverter to change DC current into AC current. Plug the charger cord into the standard outlet on the inverter to charge the battery.

    C-100 and Freedom Battery Compatibility

    The C-100 battery and Freedom battery are compatible and may be used together in dual configuration to power a CPAP device. Use the DC Power Pigtail Cord for C-100 & Freedom Travel Battery Packs for CPAP Machines to pair the batteries to the unit.

    Choosing the Correct Connector Tip

    Machines which require AC power will have to be powered using the included inverter. Some devices can be powered from DC power and would use the included connector tips and pigtail cord to connect directly to the battery. The manufacturer offers the following information for connector tip selection:

    1. Choose the connector tip that most closely matches in size visually to the DC connection of the device.
    2. Attempt inserting the connector tip into the DC connection. If the correct connector tip is used, it should fit easily and not have to be forced.
    3. Once the connector tip with the most secure fitting is found, connect it to the female end of the DC power pigtail cord. If the connector tip is loose, try others that may have a more secure fit.

    "ON" Lights When Using C-100 Batteries in Tandem With The Pigtail Cord: When running two C-100 batteries connected with the pigtail cord, the "ON" light on the battery with the greatest voltage will light up. However, if both batteries are at, or near the same voltage, the "ON" lights on both batteries will alternate in lighting up.

    Preventing Overdraw

    When the C-100 Battery is paired with a combination of CPAP accessories and a CPAP machine which is running at higher pressures, power to the device and/or accessories may be disabled. If this is encountered, try removing an accessory such as the heated humidifier or heated tube to decrease the power being drawn from the battery.


    • Because the cell contents are corrosive, do not abuse the battery in ways that could result in them being exposed. This includes dropping, striking, or crushing the battery.
    • The battery should not come in contact with moisture of any kind.
    • Discontinue use of any component, including connectors, cables, or the battery itself that appear to have signs of damage.
    • Use the included charger only.
    • The battery should not be exposed to extreme heat or fire. Explosion may occur.
    • Do not disassemble or incinerate the battery.
    • Use of the C-100 Battery Pack with devices that require higher wattage may result in the battery shutting off to protect from overrun.
    • Store in a cool, dry place out of direct sunlight and away from metal objects and heat.

    Battery Charge: As with all rechargeable lithium-ion batteries, the max charge held will gradually decrease over time due to use and age. The average lifespan under normal conditions is 400-500 battery cycles.

    Battery Run Times: Run times will vary greatly depending on several factors: device pressure, use of a heated humidifier or heated tube, use of a inverter or converter, and altitude. Use of the included inverter will reduce the run time of the battery by nearly half.

    8 Amps Maximum Power Demand: The C-100 Battery can provide power for devices which require up to 8 amps. As a note, most CPAP machines operate between 0.5 and 4.5 amps.
