CPAPMan's top manufacturer for CPAP battery backups is Battery Power Solutions (BPS). The Super 12 VDC CPAP Battery Pack from BPS is a reliable and durable pack that works with almost every CPAP and BiPAP machine. The pack allows your machine to run overnight without a power source, which is ideal for patients traveling or for when the power goes out. This pack takes only three or four hours to charge.
The Super 12 VDC is BPS's latest battery solution. Previously they produced the C-222 battery pack and the C-444 pack. Both items are now discontinued at CPAPMan.
