Helping CPAP users stay powered wherever they sleep

Andrew McGaffey works with EXP PRO customers who need reliable battery power for CPAP therapy while traveling, camping, living off-grid, or preparing for a power outage. For more than five years, he has helped CPAP users work through real-world questions about battery capacity, machine compatibility, charging, runtime, cords, airline requirements, and backup-power setup.

His experience comes from working directly with EXP PRO batteries and assisting people who depend on CPAP equipment every night. Rather than treating portable power as a collection of technical specifications, Andrew focuses on how a battery will actually be used: which CPAP machine it must power, how many nights it needs to last, whether heated humidity will be used, and where the customer plans to take it.

Andrew also helps travelers understand the additional requirements that come with flying with lithium batteries. His work includes explaining watt-hour limits, carry-on requirements, airline approval policies, UN 38.3 documentation, and the practical steps travelers can take before arriving at the airport.

Areas of expertise

• Camping and off-grid CPAP power
• Emergency CPAP battery backup
• Charging, pass-through power, and cord selection

Practical experience behind the advice

Many CPAP battery questions do not have a useful one-size-fits-all answer. Actual runtime can change based on pressure settings, humidification, heated tubing, mask leakage, battery temperature, machine model, and the efficiency of the power connection.

Andrew's approach is to explain those variables clearly and help users make realistic plans. This includes distinguishing between published battery capacity, estimated CPAP runtime, measured product specifications, and airline-specific policies that can change over time.

Through his work with EXP PRO, Andrew has developed hands-on familiarity with portable CPAP power systems and the questions that matter most to the people using them. His goal is to make battery information easier to understand without oversimplifying important safety or travel considerations.

Editorial approach

Content written or reviewed by Andrew is informed by EXP PRO product specifications, direct product familiarity, recurring customer questions, CPAP manufacturer documentation, battery transportation standards, and published airline policies.

Because airline requirements and product information can change, EXP PRO content is reviewed and updated as new information becomes available. Readers should always confirm current requirements directly with their airline before traveling.
