Power Supplies
FreeStyle can be powered in four different ways – the internal battery, a Universal AC/DC power supply and an optional AirBelt
battery belt in combination with the unit’s internal battery.
1. Internal Battery: A rechargeable internal battery is located within each FreeStyle unit. When it is fully charged, it
supplies power to the FreeStyle unit for up to 3 ½ hours. An audible alarm sounds when the battery power is getting low.
The alarm is discussed in the Alarm/Light Indicators section of this manual.
Battery Charging: To charge the internal battery, connect FreeStyle to either the Universal AC/DC power supply and a
100-240 volt, 50/60 Hz AC power outlet, or connect it to a DC power outlet in an automobile (boat, motor home, etc.). A
discharged battery requires approximately 3 ½ hours to fully charge. It is recommended to recharge the battery, even if
only partially depleted, as often as possible.
2. Universal AC/DC Power Supply: A Universal AC/DC power supply allows FreeStyle to be connected to a 100-240
volt, 50/60 Hz outlet. The power supply converts 100-240 volt AC to a DC voltage for the FreeStyle unit. When
FreeStyle is operated with the Universal AC/DC
power supply, power from the AC outlet powers the unit and recharges
FreeStyle’s battery simultaneously.
3. Optional AirBelt (External Battery Belt): FreeStyle can also be powered by an external battery belt. This belt can be
worn around the waist, and when used in combination with a fully charged internal battery, supplies power to FreeStyle
for up to 10 hours. The belt pack connects to the FreeStyle unit’s power inlet, and it can be recharged by connecting it to
the battery belt’s own AC power supply.
When using the AirBelt with a fully charged internal battery, the FreeStyle’s internal battery will deplete before the
AirBelt. The AirBelt must be connected to the FreeStyle unit before the FreeStyle’s internal battery is depleted. Observe
and connect the AirBelt to the FreeStyle unit before its internal battery discharges to 25% or less.
For oxygen concentrators equipped with batteries:
1. When connected to AC or DC power, the unit’s battery charges until it reaches full capacity, either while the
unit is operating or turned off.
2. If the internal battery fully depletes and the Oxygen Concentrator shuts down, the unit cannot be restarted
with the optional AirBelt. Should this occur, connect your Oxygen Concentrator to its AC or DC power supply
for a short period of time in order to provide sufficient internal battery power to start the unit. AirBelt can then
be connected to provide additional run time.
