Versatile and Comfortable 4-Way Custom Carrying Case

Being comfortable when you carry your oxygen is a must. If you aren’t comfortable then you aren’t going to want to be as active… With the LifeChoice Activox 4L you are given 4 different carrying options:

  • Over your shoulder
  • Like a briefcase
  • Around your waist
  • Like a backpack

With the 4-way carrying case, two of your carrying options are hands-free and they are perfect if you have bad shoulders.

Using the backpack will take the strain off of one shoulder and center the weight of the concentrator over your whole body instead of being on one side.

Carrying the 4L around your waist will completely take your shoulders out of the equation and it will put the weight of the concentrator on your waist which might be easier to handle.

No other portable oxygen concentrator offers this kind of versatility. And the ones that offer a backpack don’t include it in the package.

Easy to Read Control Panel

The LifeChoice Activox 4L is extremely user-friendly. It is equipped with a unique transflective display that is easy to read in direct sunlight or in the dark! The display will show you the flow rate your concentrator is set to and your remaining battery life for the internal and external battery.

The large push buttons make operating your 4L simple. Each one is labeled with it’s own function. The ”+” and “-” buttons change your flow rate, the arrows help you navigate the menus on the screen, and there’s even a button to mute your alarms if you are worried your alarms will disrupt others around you.

Above the mute button there is an LED indicator for your alarms. So if you do mute your alarms you will still be able to know if something is wrong with your concentrator.

Charging Virtually Anywhere

Because the Activox 4L has such great battery life you won’t need to stress out about needing to recharge very often. However, wiht the AC and DC power supplies you will be able to recharge your internal and external battery virtually anwhere!

The AC power supply is for home use. It is equipped with a 110v power cord to plug into your wall outlet. While your Activox 4L is plugged into the AC power supply it will recharge your batteries and supply you with oxygen. This will allow you to use your concentrator for nighttime oxygen delivery with the sleep mode technology!

The DC power supply allows you to recharge your batteries on the go! It is equipped with a 12v power cord that plugs into any 12v outlet or cigarette lighter in your car, truck, RV, or boat! While your Activox is plugged into the DC power supply it will recharge your battery and supply you with oxygen on all 4 settings.

Auto Mode Technology and Pulse Wave Delivery

The LifeChoice Activox 4L is equipped with two different technologies that make it ideal for 24/7 use! Like a few of the other portable concentrators on the market, the Activox 4L can actually be used for nighttime oxygen delivery!

It is equipped with Auto Mode technology which reacts to your breathing rate to instantly adjust the flow of oxygen. When the Auto Mode technology recognizes your breathing rate is slowing it increases breath detection sensitivity by 10 times!

Pulse Wave delivery ensures that you receive the full bolus dose of oxygen when you inhale. A lot of studies have been done that show oxygen gets accidentally wasted if it’s not delivered quick enough and properly. The Pulse Wave delivery ensures the bolus dose is delivered in congruence with your breathing pattern so minimal oxygen is wasted.
