Q: Are these CPAP Battery Packs safe for travel?

A: Yes, these cpap battery packs are safe for travel on any airline, domestic and international. The battery fits all of the Department of Transportation regulations which are batteries must be under 300 watt hours or 25g Equivalent Lithium Content (ELC). The specifications on our battery are: 12 volt output, 14.7 volt input, and 7.8 amp hour. For traveling purposes those specs convert to 115 watt hours or 9.7 ELC, well under the requirements.

We believe that if you make a minimal profit and just offer a great product for less than any other CPAP battery, we will all be better off.
