MAXOAK K5 CPAP Battery Backup


This CP Power Bank was developed to after finding that there are many CPAP Users, but there is no Massive Capacity power bank designed for CPAP machines. The MAXOAK K5 is just the product for that purpose when hurricanes, tornadoes, high winds, floods and other seasonal disasters have the potential to cause power outages in your area. This can be a problem if you use a CPAP machine for sleep therapy. It’s also the typical travel season when people visit friends and family for the holidays. Fortunately, alternatives for effective and affordable CPAP power bank are currently available.

The final charge time maybe different according to how you set your cpap settings such as pressure, humidifier and heater. Even with the same brand, the charge time is different on whether the pressure is fixed or flexible/auto-adjustable. The pressure will go higher if it is a self titrating unit and worn with mask worn on, the CPAP will drive more current than taking off the mask. A full face mask will also drive more current than nasal mask, so multiple factors can affect the current draw, that make the final charge time different.
