Weight and battery life are the questions every buyer asks, and the iGo is built with both in mind. At roughly 19 pounds with an integrated cart and wheels, it's designed to roll rather than be carried long distances, and a rechargeable battery keeps you running when you're away from an outlet. The unit also accepts AC and DC power, so it charges at home, in the car, and — for many airlines — during flight, since the 306DS is FAA-accepted for air travel. Always confirm requirements with your carrier before you fly.

An iGo replaces the recurring cost and delivery hassle of oxygen tanks by drawing oxygen from the ambient air, so you're never scheduling refills or worrying about running empty on a long day out. Because oxygen concentrators are prescription devices, you'll need documentation of your prescribed liter flow and delivery mode before ordering.
