Somnetics Transcend 3 Auto MiniCPAP

An update to a classic


In 2019, Somnetics released the new Transcend 3 Auto miniCPAP, the much awaited auto-adjusting model in the classic Transcend CPAP Series. The Transcend 3 CPAP machine offers many of the same features as previous Transcend machines while adding in a whole host of new ones, all while maintaining a lightweight and compact design that can fit in any suitcase, briefcase or any other travel bag.






As a CPAP user, whether you’re going on a vacation, business trip or visiting family and friends, the last thing you want to worry about is getting a good night’s sleep. However, with so many accessories and add-ons, it can be overwhelming to figure out how to travel with your bulky home CPAP machine.

Somentics is looking to relieve that stress by releasing the Transcend 3 Auto miniCPAP, a compact yet sturdy Auto CPAP machine that can not only serve as a home machine, but also as an effective travel CPAP for CPAP therapy on-the-go!

Features at a Glance

Durable Design

Despite being able to fit in the palm of your hand, the Transcend miniCPAP is a durable and rugged device that can withstand all of the bumps you may come across while travelling. Its silicone base makes the Transcend 3 an incredibly stable machine, able to be used anywhere without fear of falling and breaking. But even if it does get damaged, Somnetics offers a 3 year warranty on the Transcend 3, the best plan in the industry.

Quality Comfort Settings

Because CPAP machines provide therapy at a fixed pressure, some sleep apnea patients may find it difficult to exhale, making it difficult to fall asleep. The Transcend’s Ramp feature begins the CPAP therapy at a lower pressure setting, allowing patients to fall asleep before experiencing higher pressures. During therapy, exhaling may still be difficult for some users, causing them to wake up. SomneticsEZEX pressure relief technology reduces the pressure during exhalation, making it more comfortable for sleep apnea patients to breathe throughout the night.


The Transcend 3 miniCPAP is FAA-approved for in-flight use, making it the perfect CPAP machine for your carry-on.

Swivel Nozzle

Unlike many CPAP machines, the Transcend 3 features a swivel nozzle, which allows for a 360 degree rotation that prevents your hose from kinking up during the night. The connection also increases the range of motion, making it the perfect CPAP machine no matter your sleep position.

Advanced Drying Mode

The Transcend 3 miniCPAP comes with a built-in drying feature that blows a low pressure airflow through the machine to completely dry any moisture and humidification build up at the press of a button.

Universal Mask and Tube Compatibility

The Transcend 3 is compatible with any mask and any hose with a standard 22mm connector, allowing users to choose the CPAP mask type and brand that is most comfortable for them.

Premium Accessories

Every Transcend 3 comes with a premium protective travel case, an international plug kit and a CPAP hose, $50 dollars worth of accessories perfect for the avid traveler.

Optional Features

Variety of Power Options

Whether you’re staying in a hotel or roughing it in the great outdoors, the Transcend 3 Auto miniCPAP comes with a variety of power accessories to make sure your CPAP machine stays powered. In addition to a DC power adapter, Somentics also sells a portable solar battery charger, making the Transcend 3 the perfect CPAP for off-the-grid travel.

Portable Battery

If the various power options weren’t convenient enough, Somnetics also sells the ultra-light, FAA-approved P8 Multi-Night Battery Pack, which can deliver up to two full nights of CPAP therapy.

Somnetics Transcend 3 Auto miniCPAP vs HDM Z2 Auto Travel CPAP Machine

Although the ResMed AirMini and Respironics DreamStation Go are among the most popular travel CPAP devices, they come at a hefty price. That’s why many sleep apnea patients on a budget would turn towards the Transcend 3 or the Z2 Auto travel CPAP machine, to get high quality therapy without breaking the bank. Although both are affordable, lightweight and compact, there are a few differences between the two.

The Transcend 3 Auto miniCPAP machine is one of the most durable and rugged travel CPAP machines on the market, with unmatched portability to boot. With its new silicone bottom as well as solar powered battery charger, the Transcend 3 is one of the best CPAP machines for adventures in the outdoors. If its durability isn’t enough, the Transcend 3 also comes with a 3 year warranty, one of the best offers of any CPAP machine.

On the other hand, the Z2 Travel CPAP Machine is touted to be among the most user-friendly travel CPAP machines out there. The Z2 is similarly priced to the Transcend 3 at an affordable $499, and is also equipped with similar comfort settings, such as the improved Z-Breathe algorithm for enhanced comfort, as well as possessing compatibility with an extended life battery. The biggest difference between the two machines is the ability to view sleep statistics and therapy data; once the Z2 is connected to your computer via its USB port, users can download and run a program called DataViewer to view their statistics.

Drawbacks of the Transcend 3 Auto miniCPAP

Although the Transcend 3 has many amazing features, it’s important to discuss some of the possible drawbacks to be aware of before purchasing.

No Therapy Tracking

Unlike travel CPAP machines like the ResMed AirMini or the Respironics DreamStation Go, the Transcend 3 does not have any companion app to track sleep statistics or therapy data.

Noise Level

While the Transcend 3 is similar in noise level to other travel CPAP machines at 26.2 dba, this is still considered too noisy by many CPAP users.

Final Thoughts

CPAP users who love to travel shouldn’t be bound to their nightstand because their CPAP machine was too bulky to carry. Whether you’re in an airplane or camping in a national park, you shouldn’t have to worry about quality sleep. The upgraded Transcend 3 is a great choice for all travelers, being affordable at $499, compact enough to fit in any bag you bring, and advanced enough to offer you the same quality therapy you receive from its at-home counterparts. Although keeping track of your sleep data isn’t its strong suit, overall, the Transcend 3 is one of the best travel CPAPs on the market.
