Schedule that vacation you have been pushing off for years or hit the road to go visit loved ones across the country without the constant worry of running out of supplemental oxygen. Silencing such an agonizing worry, the SimplyGo Mini DC power supply will provide you with a method of portable charging. With the DC power supply you will be able to charge and power your SimplyGo Mini in a car, truck, SUV, R.V., boat, or train, as it is compatible with any 12 volt cigarette styled power outlet. During charging you will have access to every pulse flow setting, however, the SimplyGo Mini will only charge on pulse settings 1, 2, or 3—the machine may not charge on settings 4 or 5 but will be powered from your vehicle's battery. The standard 8-cell battery requires up to 4 hours to fully recharge, while the extended 16-cell battery needs up to 8 hours to reach a full charge. The DC power supply is designed to fit in the compact accessory bag, and when using the carrying case, there is an opening for seamless access to the power input port without needing to remove the case. Always ensure the car is turned on before charging to avoid draining your vehicle's battery.
