The OxyGo NEXT NG is a lightweight pulse-dose portable oxygen concentrator. It is designed for people who want a machine that is easy to carry, simple to operate, and available with longer battery options.
It weighs 4.8 pounds with the standard battery, making it light enough for many people to carry over the shoulder.
Choose the lighter standard battery or the larger extended battery for longer days away from a charger.
Its small size, removable batteries, AC power, and vehicle cable make it useful for everyday trips and vacations.
The machine can run from household power, vehicle power, or a charged battery.
The concentrator includes a five-year limited warranty. Batteries and columns have shorter coverage.
The batteries and columns can be replaced without sending the whole machine away for routine replacement.
The OxyGo NEXT NG is designed to go where you go. Many buyers use it for appointments, shopping, family visits, church, restaurants, and travel.
With the standard battery, the total weight is 4.8 pounds. The extended battery adds about one pound but provides much longer battery time.
It is not the very lightest portable concentrator. Its strength is balance. It gives you six pulse settings, strong battery choices, a five-year limited concentrator warranty, and a size that many people can still carry comfortably.
Both batteries can be removed and replaced by the user.
