The Freedom V2™ CPAP Battery gives you the freedom to power your PAP device when and where you need it!

The Freedom V2™ is the perfect solution for outdoor and travel enthusiasts. It’s great for use in tents, RVs, travel trailers, and boats. It's also ideal for those who love to travel abroad as it meets FAA requirements for lithium-ion batteries that can be taken in carry-on baggage. 

When inclement weather strikes you can use the Freedom V2™ CPAP Battery as a backup power supply during power outages so you never have to worry about another sleepless night without your CPAP machine.

The easy-to-read digital display indicates the remaining charge level of the battery and if you need more power you can always pigtail two Freedom V2™ batteries together.

Going off the grid or just need even more time to enjoy your travel adventures? With the addition of the Auto Charge DC Cable or Sine Wave Power Inverter you can charge the Freedom™ in a vehicle; or with the addition of the SunPower 50W Solar Panel you can charge it using the power of the sun. 

As an added bonus the Freedom V2™ CPAP Battery features a 5V USB port and a DC input cord that let you charge most common handheld devices such as cell phones, MP3 players and tablets.
