The runs times are estimates based on the relative power draws of each machine and may vary depending on mask fit (air leaks). If your pressure settings are based on a min/max (ie. BIPAP), please use the higher number. The pressure ranges do not account for every possible setting, but should provide useful information in determining estimated run times. Air Travel Guidelines Up to two of the EXP48PRO batteries can be brought with you in your carry-on luggage. The FAA regulations state the limit is 160 watt hours (Wh), and the EXP48PRO only contains 153.6 Wh per battery. Please check current FAA regulations and the individual airline rules prior to airline travel. Do not put EXP PRO batteries or any other lithium batteries or devices containing lithium batteries in checked baggage of any type. If allowed by FAA regulations and individual airline rules only take in carry-on baggage.
