This Micro USB Charger is used to charge the internal battery in all Sleep8 CPAP Cleaner Sanitizers.
Sleep8's Micro USB Charging Cord includes an AC Power Supply for use in North American (U.S.A. & Canada) Power Outlets. It can also be plugged into the USB outlets on most computers, modern cars, and other USB enabled digital devices.
Usage Information: To charge your Sleep8's internal battery, just plug the cord into the Sleep8's Micro USB port (hidden beneath the blue dust cap) and then plug the charger into an external AC or USB power source. When you plug it in the Sleep8 will beep once to let you know the internal battery is charging. While the battery is charging Sleep8's screen will dim and the battery icon will shine bright to display current battery levels. Sleep8's charger WILL NOT overcharge the battery so it can be left in overnight to ensure a full charge whenever you need it.
