Is the CoughAssist T70 portable?

The Philips Respironics CoughAssist T70 is capable of being used with a specially designed battery. A fully charged battery can provide up to four treatments on a single charge. There is also a DC power adapter for the CoughAssist T70 which is capable of powering the unit while plugged into your vehicle. There is also a carrying case designed for easier transportation but the CoughAssist should not be used while it is inside the case.
