How is Caire SeQual Eclipse 5 better than the previous model, the SeQual Eclipse 3?

While the Eclipse 5 appears to be quite similar to the SeQual 3 portable concentrator from the outside it provides some important technical enhancements over the Eclipse 3 edition. Even when running on DC vehicle control, both continuous flow and pulse dose settings are available. With Eclipse 5, for all pulse dose settings up to 192 mL and all continuous flow settings up to 2 LPM, users can recharge their batteries while the device is attached to DC vehicle power. For some users, this is a major enhancement over Eclipse 3.
