Travel CPAP batteries are the perfect accessory to maintain consistent therapy on the go. CPAP machines typically run on AC power via an electrical outlet, but that isn't always available. For overnight flights, car rides, and camping trips, portable CPAP batteries can provide power for a night or two on a single charge to ensure you receive the therapy you need. Even if you travel infrequently, having a CPAP battery pack at home can be useful in a pinch if your power goes out. Like other accessories, it's important to check that your machine is compatible with a given CPAP battery before purchasing.
