Xiaomi LOWRA ROUGE SL620 Cordless Straightener: Product Overview
The Xiaomi LOWRA ROUGE SL620 Cordless Straightener is a rechargeable hair styling brush developed for users who want greater flexibility during their styling routine. Unlike traditional corded straighteners, this model uses a built-in rechargeable battery, allowing cordless operation without keeping the device connected to a wall socket.
Its brush-shaped construction combines the familiar design of a hairbrush with a heated straightening system. As a result, users can comb through sections of hair while applying controlled heat to achieve a smoother and more manageable appearance.
One of the main attractions of the SL620 is its adjustable temperature system. It offers nine temperature levels within a range of 150°C to 230°C. Therefore, users can select different heat settings according to their styling preferences and hair requirements.
Additionally, the device uses MCH (Metal Ceramic Heater) technology to support rapid heating. Published product specifications indicate an approximate heating time of 30 seconds, helping reduce the waiting time before styling.
The cordless construction also makes it convenient for different environments. You can keep it in your personal care collection, take it on trips, or use it for quick hairstyle touch-ups when a conventional power connection is not convenient.

| Technology | Plasma Technology |
| Safety Design | Anti-Scald Comb Structure |

| Weight | Approximately 274.5g |
| Operation | Cordless and Rechargeable |
These specifications make the SL620 an interesting option for people looking for a portable hair straightening brush with adjustable heating and rechargeable operation.
Cordless Design for Flexible Hair Styling
One of the most useful features of the Xiaomi LOWRA ROUGE SL620 Cordless Straightener is its wireless design. Traditional hair straighteners usually require a direct connection to an electrical outlet during operation. This can limit movement and make styling less convenient in certain situations.
However, the SL620 uses a built-in rechargeable battery to support cordless styling. Consequently, you can move more freely while arranging your hair without managing a connected power cable.
The cordless design is particularly useful for:
- Quick hairstyle touch-ups before leaving home.
- Personal grooming while travelling.
- Styling in locations with limited access to electrical outlets.
- Keeping your dressing area free from unnecessary cables.
- Carrying a rechargeable hair styling device in your travel accessories.
Furthermore, its compact brush-style construction makes it easier to handle and store compared with some traditional styling appliances.
For people who value portability, the cordless design is one of the defining characteristics of this model.

Nine Adjustable Temperature Settings from 150°C to 230°C
Different hair types and styling requirements can call for different temperature levels. A single fixed temperature may not offer the flexibility that users want from a modern hair styling appliance.
The LOWRA ROUGE SL620 addresses this requirement with nine adjustable temperature settings, covering a temperature range of 150°C to 230°C.
This adjustment system allows users to select a preferred heat level instead of relying on one temperature for every styling session.
The available temperature range provides flexibility for different styling preferences:
| Temperature Range | General Styling Consideration |
| 150°C–170°C | Lower-temperature styling |
| 180°C–190°C | Medium-temperature styling |
| 200°C–210°C | Higher-temperature styling |
| 220°C–230°C | Highest available temperature settings |
The selected temperature should depend on hair condition and styling needs. Lower heat is generally preferable when sufficient for the desired result. Excessive heat can contribute to dryness and hair damage, so appropriate heat protection is important.
Moreover, having multiple temperature settings makes the SL620 more adaptable than a straightening brush with only one fixed heating level.
MCH Fast Heating Technology
Heating performance is another important consideration when choosing an electric hair straightener.
The Xiaomi LOWRA ROUGE SL620 features MCH (Metal Ceramic Heater) technology, which is designed to provide rapid heating and support consistent heat distribution.
According to published product specifications, the SL620 can reach its operating temperature in approximately 30 seconds.
This quick heating performance helps reduce preparation time, especially when you need to arrange your hair before work, school, an outing, or another daily activity.
MCH heating technology is a key part of the device’s overall design. It supports the heating function while working alongside the adjustable temperature control system.
Instead of waiting for an extended period, users can prepare the device for styling in a relatively short time.
However, actual heating time can vary depending on the selected temperature, battery condition, and operating environment.
Plasma Technology for Smoother-Looking Hair
Static electricity and frizz can make hair appear less manageable. Plasma technology is included in the LOWRA ROUGE SL620 as part of its hair styling system.
The technology is designed to help reduce static and improve the appearance of smoothness during styling.
Published product descriptions also associate the device with negative-ion technology. Some listings specify an output of up to 40 million negative ions, while other supplier information describes a different plasma output. Therefore, the exact ion-output figure should be confirmed from the manufacturer’s packaging or documentation.
The main purpose of this feature is to support a smoother-looking hairstyle by helping manage static and frizz.
When combined with the heated brush structure, plasma technology adds another styling function to the SL620.
It is important to remember that ionic or plasma technology does not eliminate the effects of excessive heat. Proper temperature selection and sensible heat-styling habits remain important.
Anti-Scald Comb Design for More Comfortable Handling
A heated styling appliance should include features that help reduce accidental contact with hot surfaces.
The LOWRA ROUGE SL620 uses an anti-scald comb structure with a protective outer design. Its double-layer comb arrangement is intended to create separation between the heated styling components and the outer contact area.
This construction helps make the brush-style appliance more comfortable to handle during normal styling.
The protective structure is particularly relevant because the device is designed to be used like a comb rather than a conventional flat iron.
Additionally, the product includes a 30-minute automatic power-off function. This feature is designed to switch off the appliance automatically after the specified period.
The automatic shut-off function provides an additional layer of convenience when managing the device.
Nevertheless, the anti-scald construction does not make the heated appliance completely burn-proof. Keep the heated parts away from skin, children, water, and heat-sensitive surfaces. Follow the supplied user manual when operating or storing the device.

9600mAh Rechargeable Battery and USB Type-C Charging
Battery performance is an important part of any cordless hair styling device.
The LOWRA ROUGE SL620 is listed with a 9600mAh rechargeable lithium battery, supporting its wireless operation. Supplier specifications describe the battery configuration as two 4800mAh battery cells.
Some product listings state that the device can provide up to approximately 90 minutes of cordless operation under specified conditions.
Actual operating time may vary depending on the selected temperature, battery condition, and frequency of use.
The device also features a USB Type-C charging interface, offering a familiar charging connection for modern electronic accessories.
Its published electrical specifications include:
- Battery capacity: 9600mAh.
- Rated power: 35W.
- Charging input: 5V/2A.
- Charging connection: USB Type-C.
- Operating voltage: 7.2V.
The rechargeable construction makes it suitable for users who prefer a cordless personal care appliance.
Furthermore, USB Type-C charging helps simplify charging arrangements because the connection type is commonly used in many modern electronic devices.
Compact and Portable Brush-Style Construction
Portability is one of the main reasons people consider cordless hair straightening brushes.
The Xiaomi LOWRA ROUGE SL620 has a compact brush-style design that combines a heated styling system with a familiar comb shape.
Its listed weight is approximately 274.5 grams, making it relatively lightweight for a rechargeable styling appliance.
The published product dimensions are approximately 200 × 46 × 43mm.
These physical characteristics make the device convenient to store with personal care accessories and carry during trips.
Its compact design can be useful for:
- Home hair grooming.
- Travel preparation.
- Quick hairstyle maintenance.
- Personal care storage.
- Occasional styling outside the home.
The lightweight construction also helps make handling more convenient during regular styling sessions.
Overall, the SL620 focuses on combining portability, rechargeable operation, and adjustable heating in one brush-style appliance.

Why Choose a Cordless Hair Straightening Brush?
Traditional hair straighteners and cordless straightening brushes serve a similar styling purpose, but their designs offer different experiences.
A traditional flat iron generally uses two heated plates to press hair between them. In comparison, a straightening brush uses a comb-style structure to work through sections of hair.
The LOWRA ROUGE SL620 combines this brush-style approach with rechargeable operation.
Here are some differences worth considering:
| Feature | Traditional Corded Straightener | LOWRA ROUGE SL620 |
| Design | Flat Iron | Heated Brush |
| Power Source | Electrical Outlet | Rechargeable Battery |
| Cordless Operation | Generally No | Yes |
| Temperature Control | Depends on Model | 9 Settings |
| Heating Technology | Depends on Model | MCH |
| Charging Interface | Not Usually Required | USB Type-C |
| Portability | Depends on Model | Compact Design |
| Auto Shut-Off | Depends on Model | 30 Minutes |
The most noticeable difference is the freedom provided by rechargeable cordless operation. In addition, its brush-style design offers an alternative to conventional flat-plate straightening appliances.
