Breas Z2 PowerShell Module for Z1/Z2 With Extended Life Battery

The Breas PowerShell with Extended Life Battery is a self-contained power accessory for the Breas Z1 and Z2 CPAP machines, letting you run your machine without being plugged into an outlet. The battery, PowerShell casing, and your Z1 or Z2 machine slide and click together into a single integrated unit.

Is This the Right Power Solution for You?

This is worth considering if you travel, camp, or otherwise need your Z1 or Z2 to run somewhere without reliable outlet access, or if you want a backup power option in case of a storm-related outage at home. It's priced as a premium accessory, so it's most worthwhile if off-grid or backup power is a real, recurring need rather than an occasional one. This listing does not include the CPAP machine itself, which is sold separately.

Key Features at a Glance

• Fully self-powered CPAP operation — no outlet required
• Slides and clicks together with your Z1 or Z2 machine into one integrated unit
• Soft, padded neoprene skin over a solid internal skeleton
• Includes a lanyard for hanging in a tent, on a headboard, or elsewhere
• Includes the Extended Life Battery, offering twice the power of the original Z1 battery
• 1–2 nights of runtime per charge, depending on pressure settings
• Automatically recharges when plugged into AC or DC power
• Doubles as backup power during a storm, outage, or blackout

A Sturdy, Integrated Design

The PowerShell is built with a soft, padded neoprene skin over a solid internal skeleton, and your battery module and Z1 or Z2 machine slide and click into place to form one sturdy, integrated unit rather than a loose battery pack connected by a cable. The included lanyard lets you hang the whole setup in a tent, from your headboard, or wherever is most convenient.

Extended Life Battery Included

This package includes the Z1 & Z2 Extended Life Battery, which offers roughly twice the power of the original Z1 battery. On average, a single battery module provides 1–2 nights of runtime between charges — lower pressure settings extend runtime, while higher pressure settings shorten it. The PowerShell is also compatible with original Z1 batteries if you already own one.

Charging & Care Tips

• Battery modules recharge automatically in the PowerShell when plugged into AC or DC power
• Your Z1 or Z2 machine does not need to be in the PowerShell for the battery to charge
• If the machine is in the PowerShell during charging, it must be in standby mode for the battery to charge
• Charge the battery occasionally even when not in regular use, to help preserve its long-term life
• Remove the battery module from the PowerShell when not in use to help preserve its charge

Built for Travel and Backup Power

Small enough to fit in your hand, the PowerShell is designed for full nights away from home — camping, flying, or otherwise off the grid. It can also serve as backup power at home, automatically taking over if you lose power during a storm or outage.

What to Know Before You Buy

This package includes the PowerShell casing and the Extended Life Battery; it does not include the Z1 or Z2 CPAP machine itself, which is sold separately. Also worth knowing: the PowerShell casing is required both to charge the battery and to run your machine on battery power — you can't use the battery and machine together without the shell, and the battery will lose charge if left inside the shell when not actively charging or in use. If runtime, proprietary charging requirements, or noise level are dealbreakers for your specific use case, it's worth weighing this against your actual travel or backup power needs before purchasing, given the investment involved.

Frequently Asked Questions

Does this include the Z1 or Z2 CPAP machine?

No. This listing is for the PowerShell casing and Extended Life Battery only. The Z1 or Z2 machine is sold separately.

Can I use the battery without the PowerShell casing?

No. The PowerShell casing is required both to charge the battery and to run your machine on battery power — the battery and machine can't be used together without it.

How long does the battery last per charge?

On average, 1–2 nights per charge, depending on your pressure settings. Lower pressures extend runtime; higher pressures shorten it.

How long does it take to recharge?

8 hours for a full recharge.

Does this work with the original Z1 battery too?

Yes. The PowerShell is compatible with original Z1 batteries in addition to the included Extended Life Battery.

Is this quieter than running on standard AC power?

Noise level is primarily a function of the Z1/Z2 machine itself rather than the PowerShell casing. If quiet operation is a priority, we'd recommend checking current customer reviews and your own machine's noise specifications before relying on this as a source of noise reduction.

Can I use this as backup power during an outage?

Yes. The PowerShell can serve as backup power at home, automatically taking over your CPAP's power supply if you lose electricity during a storm or outage.
