CPAP Batteries & Chargers

CPAP batteries and chargers allow a CPAP device to operate without access to a power outlet. They are essential for travel, camping, off-grid use or during power outages.

A suitable CPAP battery ensures continuous therapy outside the home without compromising treatment effectiveness or safety.

What are CPAP batteries and chargers used for?

CPAP batteries provide an independent power source to operate a CPAP device when electricity is unavailable. Chargers are used to recharge batteries or power the CPAP device directly, depending on the setup.

They are especially useful for travel, overnight stays without power or as a backup solution during electrical outages.

What types of CPAP batteries are available?

The main types include:

• portable CPAP batteries: compact and designed for travel,
• high-capacity batteries: for extended runtime,
• FAA-approved CPAP batteries: compliant with airline regulations,
• solar-compatible solutions: for autonomous recharging.

How long can a CPAP battery last?

Battery runtime depends on several factors: battery capacity, CPAP device model, prescribed pressure settings and the use of heated humidifiers or heated tubing.

In general, battery life is longer when heated features are disabled.

How to choose a CPAP battery or charger?

When selecting a CPAP power solution, it is important to consider:

• compatibility with the CPAP device brand and model,
• required capacity and desired runtime,
• connection type (DC output, specific adapters),
• intended use (travel, emergency backup, daily use).

Using an incompatible battery or charger may damage the device or compromise therapy safety.
