Lifestyle Rhythm P2-S4 Battery (Single, Double, Triple)
Battery life is often on of the most important features when picking a portable oxygen concentrator. When you go with the Lifestyle Rhythm P2-S4 portable oxygen concentrator you have the ability to choose from 3 different sizes of battery options to meet your lifestyle demands!
This is new in the portable oxygen space, as other units at most have 2 battery options, but there’s never been a triple battery until Rhythm!
Now you can pick from the lightest overall package by going with the single battery, the double battery gives you the perfect balance of weight and battery life, or if you want the longest operation aways from a power source in exchange for a slightly heavier package the triple battery will be what you’re looking for!
Expected Battery Life
The P2-S4 single battery will provide you with up to 2.5 hours, the double up to 4.8 hours, and the triple up to 7.2 hours of interruption free oxygen therapy before you need to recharge the battery or plug it into a power source.
You can plug your Rhythm P2-S4 into a power source such as the AC power supply while at home, the DC power supply via your vehicle’s cigarette lighter outlet. And of course, both of these accessories are included with your purchase from 1st Class Medical.
Plan on having multiple batteries? You can use the optional external battery charger to charge extra batteries, externally from your Rhythm P2-S4 concentrator.
