The Invacare Solo is a versatile and dependable continuous flow and pulse dose portable oxygen concentrator by Invacare, that allows even those who need a high dose of oxygen go wherever they want to go. The name Solo even implies that you can independently travel about without needing to recharge as quickly, thanks to the powerful rechargeable battery that comes with it.
This is also an FAA approved portable model, which means you can take it to use on a passenger flight to or from US soil.
The continuous flow settings are 1, 2 and 3 LPM (Liters Per Minute) and the pulse doses are the settings from 1 to 5. You can count on an average oxygen purity of around 93% on all settings.
The battery will last around 1.35 hours on the highest continuous flow setting, and 4.5 hours on the pulse dose setting of 2. The battery duration depends on which setting you are using. It you use the lowest pulse dose setting, you will have the longest battery duration.
However, you always need to have it on the setting prescribed to you, which is why the Invacare Solo battery is made to be so powerful, and able to recharge from 0 to 100% in around 4.5 hours. You should take the time to recharge any time you are sitting still, either with the AC or DC adapters. Use the DC adapter while you are on your way to your destination for increased battery life while you are on your feet.
The Solo is 20 lbs with the battery, but it's easy to bring with you wherever you need to go, with the mobile cart, which is lightweight and easy to maneuver, even through the tightest spots. It sits at 16.5 inches tall, 11 inches wide and 8 inches deep and has a sleek design, so you won't need to worry about it being in the way, or getting snagged as you make your way around.
