AirSep - Focus operation coiled cable (on/off switch)

AirSep - Focus Battery Operation Coiled Cable (on/off switch). 

This product is a replacement part to the standard cable included in conjunction with external batteries. Like its counterpart, it lets you connect the concentrator unit battery. 

This cable is provided with a plastic coating coiled spring that highly increases the resistance and allows a small footprint compared to its counterpart simple. It also comes with an on/off switch.
