Dual Configuration

Respitag Travel Battery can be used as either a standalone battery, replacement battery cell or an additional battery placed in a dual configuration to increase power to the CPAP device. If using the travel battery along with another battery to increase power, follow these steps:

  1. Use the pigtail connector to link both batteries to the "DC Out" port.
  2. Pair the pigtail cable with the appropriate connector tip Connector Tips for Respitag Travel Battery Pack for CPAP provided or the appropriate DC cord.
  3. Plug the connector tip or the DC cord into the DC outlet on the CPAP device.


Please Note: Once a battery is fully depleted, the other battery will begin outputting power. The pigtail connector and DC cord are not provided with the purchase of this battery.

When both batteries are being used in dual configuration, the batteries can be charged at the same time.

  1. Use the pigtail cord to link both batteries to the "DC Out" port.
  2. Connect the power pigtail cord to the AC charger (power supply and cord).
  3. Plug the AC Charger power cord into an AC outlet.
  4. When fully charged, the display screen will signal that the charge is complete. Always disconnect the battery(s) from the wall outlet when fully charged.


Please Note: For international charging purposes, AC current between 100V to 240V is acceptable to charge the battery. Use an appropriate adapter as needed. The pigtail connector and AC Charger are not provided with the purchase of this battery.


Digital Screen Design

Peace of mind can be found in the digital screen featured on this battery. For easy reading, press the round button found next to the screen to light the display and view the battery's charge. After a few seconds, the blue backlight will turn off, allowing the user to fall to sleep without disturbance.

Backup Power Capabilities

If connected to AC power while using the Respitag Battery, the unit will recognize the source of AC power and distribute it to the CPAP device, bypassing the battery. The AC battery charger must be connected to the "DC In" port, while the connector tip or DC cord must be plugged into the "DC Out" port and into the CPAP machine.

In instances such as a power failure, when AC power is not available, the Respitag Travel Battery is designed to use its stored charge to power the device. If connecting the CPAP machine to a humidifier or using at a high altitude, it may be helpful to connect the unit to two battery cells in order to create a longer run time.

*Note: Needs an additional connector for  20V+ demand ; not provided along with the unit.

Alternative Battery Charging Options

  • Use the BPS Auto Charge DC Cableto charge the Respitag Travel Battery from a vehicle's cigarette lighter. Please Note: The vehicle must be running to charge the battery.
  • The 150W Sine Wave Power Invertercan be used with the AC charger to convert the DC power to AC power in order to charge the Respitag Travel Battery.

In all instances allow 4 to 5 hours to fully charge the battery after it has been completely discharged.

Compatible with Handheld Devices

Most handheld devices such as mobile phones and tablets can be powered and charged from the Respitag Battery's 5V USB along with a USB cord. As an alternative to the USB cord, use a DC cord and DC Input Cord for C-100 & Respitag Travel Battery for CPAP Machines to power the device from the battery. If seeking to charge a device without a USB cord, DC power cord, or 12V capabilities, use the 150W Sine Wave Power Inverter to power the device using its AC charger.

Battery Charging Tips

  • First Time Charging:When charging the Respitag Battery Pack for the first time, charge the battery completely to 100%. The power supply may become slightly warm to the touch during charging, which is normal.
  • Charging from a DC Source:Using the OPTIONAL DC to DC Cable for Respitag Travel Battery Packs, the battery can be charged directly from another DC source using a cigarette style 12V outlet. If doing so in a vehicle, it must be running. Another option for charging from DC power is to add the 150W Modified Sine Wave Inverter to convert the DC power to AC to use the standard charger.
  • International Charging:The battery can be charged internationally, as the charger can be used with AC currents from 100V to 240V. Plug adapters such as the World Traveler Power Adapter Plugs will be needed to convert the outlet.
  • Dual Battery Charging:Using the included power pigtail cord, two batteries can be charged at once using the battery charger. Simply plug the single end of the pigtail cord into the charger, and then the split end into the "DC In" port of both batteries.
  • Charge While in Storage:Before storing, fully charge the battery. The battery will self-discharge approximately 20% every 30 days. If storing for an extended period, charge the battery once every 90 days to at least 50% capacity.

Battery Run Times

Run times will vary greatly depending on several factors: device pressure, use of a heated humidifier or heated tube, use of an inverter or converter, and altitude.

Preventing Overdraw

When the Respitag 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.
