Product Features
Pocket-Size Weight and Dimensions
The Transcend Micro 510 is a travel-size CPAP machine that weighs 0.48 lb and measures 3.6 in x 3.6 in x 2.4 in. It fits easily in a bag without taking up much space while still supporting a full pressure range. Available colors include Midnight Blue, Petal Pink, Graphite Gray, and Birch White.
CPAP and Auto-CPAP Modes
The Micro 510 runs in CPAP mode or Auto-CPAP mode. CPAP delivers one fixed pressure, while Auto-CPAP adjusts within a set range as you breathe. Default settings are 4 to 20 cm H2O, meaning centimeters of water pressure. Ramp mode can begin lower and increase gradually for a smoother start.
Standard 22 mm Mask Compatibility
The Micro 510 uses a standard 22 mm mask connection, which is the most common hose connection in CPAP setups. If your current mask already uses a 22 mm connector, you can usually keep it. No brand-specific adapter is needed, only a compatible mask and hose configuration for your setup.
Exhalation Relief for Easier Breathing Out
The Micro 510 includes exhalation relief, which lowers pressure slightly when you breathe out so exhaling feels more comfortable and natural. It works with the therapy mode you are using, including Auto-CPAP. If pressure changes feel uncomfortable, your provider can adjust this setting based on your prescription and comfort needs.
Waterless Humidification With AirMist HME
The Micro 510 uses waterless humidification through an HME, or Heat Moisture Exchanger. Instead of a water tank, the AirMist HME collects humidity from your breath and surrounding air, then recirculates it through the circuit. The box includes one AirMist HME, one cartridge, and one filter for waterless use setup.
27 dBA Sound Level and Muffler Option
The Micro 510 is rated at 27 dBA, a decibel scale adjusted to reflect how people hear sound. A WhisperSoft Micro muffler is included and can help reduce noise further. You can set it up with or without the muffler, depending on the airflow path you prefer for travel use.
AC Power Specs and International Voltage Range
The included AC power adapter supports 100 to 240 VAC at 50 to 60 Hz, which works with many outlet voltages when used with the correct plug adapter. VAC refers to wall power, and the adapter outputs 19 VDC at 2.1 amp to power the device safely during travel internationally.
Optional Battery Power With PowerAway
The Micro 510 does not have a built-in battery, but it can be used with the Transcend Micro PowerAway battery for up to 17.5 hours of portable power. PowerAway is an external option for travel or backup use, helpful on flights, camping trips, or places without a wall outlet reliably.
MySleepDash App and Data Types
The MySleepDash app lets you view therapy information from the Micro 510. It can track therapy hours, show leak summaries, monitor therapy data, and share therapy details. The device provides compliance data and advanced data. Compliance data is the usage information often requested for insurance or provider follow-up visits and checks.
Drying Mode, Auto Altitude, and Flight Use
The Micro 510 includes Drying Mode, auto start, auto stop, and auto altitude adjustment up to 8,000 ft. Drying Mode helps clear moisture after therapy and reduce dampness in the circuit between nights. FAA refers to Federal Aviation Administration, and TSA relates to carry-on screening during air travel at airports.
What Comes in the Box
The box includes the Micro 510 Auto CPAP machine, hard shell travel case, TransFlex 6-foot hose, WhisperSoft Micro muffler, hypoallergenic air filter, AC power adapter, AirMist HME, and the Micro 510 user guide. This helps you confirm what is included and what you may still need separately for therapy items.
3-Year Warranty and Support Coverage
The Transcend Micro 510 includes a 3-year warranty, which gives you longer coverage if the device needs service during that period. It is also supported by the manufacturer, which is helpful for a travel machine that gets packed often and used in different places. Keep your proof of purchase and warranty details for claims.
TSA and FAA Compliant for Travel and In-Flight Use
The Transcend Micro 510 is TSA and FAA compliant, so it can travel in your carry-on and be used in flight. That makes it easier to keep therapy with you on long trips instead of checking the device or going without it. Airline rules can vary, so confirm your carrier’s policy before flying.
Do I need a prescription (Rx) to buy the Transcend Micro 510 Auto CPAP?
Yes. The manufacturer states a prescription is required to purchase the Transcend Micro 510 Auto CPAP. Your Rx should include CPAP or APAP wording and your settings (either a single pressure or a pressure range), plus your clinician’s signature and contact details. The device is shipped pre-programmed based on that prescription.
What therapy modes does the Transcend Micro 510 support?
It supports CPAP and Auto-CPAP (APAP) therapy modes, according to the manufacturer. Auto-CPAP adjusts pressure as you breathe during the night, while CPAP delivers a fixed pressure. Your clinician’s prescription determines which mode and settings are programmed.
What pressure range does it cover?
The manufacturer lists a 4–20 cmH₂O therapeutic range for the Transcend Micro 510. That range is commonly used for CPAP therapy settings, but the exact pressures you use should match your prescription. The device is intended to deliver the prescribed pressures consistently, whether at home or while traveling.
What comes in the box with the Transcend Micro 510?
The manufacturer lists these included items: the Transcend Micro 510 Auto CPAP device, a TransFlex 6-foot hose, WhisperSoft Micro muffler, hypoallergenic air filter, AC power adapter, AirMist HME (waterless humidification component), a hard shell travel case, and the user guide. Masks are not listed as included.
Will it work with my current CPAP mask?
Yes, if your mask uses a standard 22 mm connection. The manufacturer states the Micro 510 is compatible with most standard CPAP masks using a 22 mm connector, so you can typically keep your current mask setup. If your mask uses a proprietary connection, you would need the correct compatible connection method.
Does the Transcend Micro 510 have a built-in battery?
No. The manufacturer states the Micro 510 does not include a built-in battery. For portable power, it can be paired with the Transcend Micro PowerAway Battery, which the manufacturer describes as providing up to 17.5 hours of runtime (usage can vary based on settings and accessories).
Is the Transcend Micro 510 OK for flying and airport security?
The manufacturer states the device is TSA/FAA compliant for carry-on and in-flight use. Airline rules can still vary by carrier and route, so it’s smart to confirm your airline’s policy before travel. If you plan to use it in-flight, check power availability and any onboard restrictions ahead of time.
How loud is the Transcend Micro 510?
The manufacturer lists a sound level of 27 dBA for the device. They also note that using the included WhisperSoft muffler is intended to further reduce perceived sound during use. Real-world sound can still change based on mask type, leaks, and where the device is positioned.
How small is it for travel?
The manufacturer lists the machine weight as 0.48 lbs and dimensions as 3.6 in × 3.6 in × 2.4 in. It’s designed to pack easily, and the box contents include a hard shell travel case. If you’re building a travel kit, plan space for the hose, muffler, and power adapter too.
Does it work internationally with different voltages?
Yes. The manufacturer lists an AC supply input of 100–240 VAC, 50–60 Hz for the power supply. For international trips, you may still need the correct plug adapter for the country you’re visiting, since voltage support is different from plug shape compatibility.
What is AirMist HME and how is humidification handled?
The Micro 510 uses an HME (heat moisture exchanger) approach for waterless humidification, and the manufacturer lists AirMist HME as included in the box. An HME is designed to capture moisture from exhaled breath and help return humidity during inhalation, without a water tank. It’s a different approach than heated humidifiers that use a chamber.
How do I view my therapy data with the Transcend Micro 510?
The manufacturer states the Micro 510 works with the MySleepDash app (Apple and Android). They describe features like viewing therapy data, leak summaries, therapy hours, and sharing therapy information. App access and what you can share may depend on your setup and how your provider manages follow-up.
