Portable oxygen concentrators can be judged on a number of aspects: weight, design, durability, and oxygen output. But the aspect that seems to get the most attention these days is battery life. Battery life is defined as the length of time that a mobile oxygen device can run on a full battery until it’s fully depleted. In general, a portable oxygen concentrator with a long battery life will afford more freedom and independence to the user whereas ones with less battery life are more likely to keep you homebound.
