Hit the road or set sail with the Invacare SOLO2 DC power supply. It plugs into any DC outlet, such as a car cigarette lighter, DC power connector in an RV, or DC port on a boat. The DC power supply takes the worry and bother out of running out of oxygen when traveling or out for a day of fun. The DC power supply makes it possible to travel or spend the day out running errands without the concern of running out of oxygen. On some settings the power supply will run the SOLO2 and charge the battery at the same time. Generally it will run and charge up to a continuous setting of 2, but it depends on the power of your car battery. Keep in mind that you should always plug the DC power cord into the outlet closest to the vehicle's battery. The SOLO2's power connector is quickly and easily accessible, with a reinforced cord that resists shorts even with frequent plugging and unplugging and connects snugly to prevent disconnection. This accessory weighs 2 pounds and operates on 12V, 15-20A power.
