Product Overview

Are you concerned about not being able to use your CPAP machine in the event of a power failure? Are you are interested in taking your CPAP on a weekend getaway, vacation, or camping where there is no electricity? At last there is a convenient, cost effective way to run your CPAP machine from an external battery source, that is less than half the weight and size of any CPAP battery pack in its class. is proud to bring you one of the smallest, lightest (1.25 lbs), CPAP battery packs on the market. Please see below for the list of compatible machines for this battery kit.

Small & Lightweight. The 1.25 lb Battery Pack is surprisingly small and lightweight. Add the carry bag and battery charger and it is still only 2.02 pounds. It features robust power that is rarely seen in battery packs twice its size and weight. The battery kit plus the included DC-12 Converter For S8™ Machines is just 3.5 pounds.

Lithium Ion Battery. This battery does not have typical "Battery Effect" issues, where you must discharge the battery before you can recharge. The lithium ion battery can be recharged at any discharge level without losing charge time due to battery memory loss. Using sophisticated circuitry, the battery pack is specially designed to limit the unit from under charging and over charging. The battery pack will take approximately 10 hours to fully charge.

Approved for Travel. This battery has been approved by the United Nations and Department of Transportation as tested safe for travel.

Estimated Run Times. Please see the "Machine Pressure and Battery Performance" feature below to estimate the battery run time for your machine at your pressure setting. Using a heated humidifier on a 12volt battery power source will significantly reduce the amount of power provided. In most cases, usage is reduced to less than half the estimated operational time. CPAPs or BiPAPs requiring inverters reduce the power time even more.

Compatible Machines. This battery kit comes with the battery and the DC12 Converter for S8 Machines. If you have any questions call our toll free number 800-356-5221 for assistance from a CPAP expert. The following machines are compatible for this kit:

Word of Caution to RESmed S8 and S8 II Machine Users

YOU MUST USE THE DC12 Converter for S8 Machines in conjunction with any battery source, when using an S8 or S8 II machine. Failure to do so can result in damage to your CPAP.

ResMed VPAP Auto 25 and VPAP ST

The ResMed VPAP Auto 25 and VPAP ST use a different cord, DC-24 Converter For ResMed. Refer to the Respironics Battery Kit for ResMed VPAP Auto 25, VPAP Malibu & VPAP ST Machines for a battery kit for these machines.

DC to AC Pure Sine Wave Power Inverter for Resmed S8 Machines

ResMed S8 machines are required to use a pure sine wave AC power source when connecting through an inverter; particularly, the ResMed S8 Compact is not DC compatible and must plug into a wall socket. The DC to AC Pure Sine Wave Power Inverter provides clean AC power to any CPAP. You will need this product to operate the S8 Compact or any other S8 machine using the standard AC plug.
