Viewing Angle

The Cello ZRTG0242 features wide viewing angles, ensuring that everyone in the room can enjoy a clear and vibrant picture.

VS Other Brands

When comparing the Cello ZRTG0242 with other brands and models in the market, there are a few factors to consider. While the Cello TV offers a compact and portable design, smart features, and a range of connectivity options, it may have some limitations compared to larger, more premium models.

However, the Cello ZRTG0242 offers excellent value for its price range and caters to the needs of travelers or those with limited space.

Value for Money

The Cello ZRTG0242 provides good value for money, considering its features and portability. It offers a compact design, smart Android functionality, a range of connectivity options, and decent picture and sound quality. While it may lack some advanced features in more expensive models, it delivers a reliable and enjoyable viewing experience at an affordable price point. If you are looking for a budget-friendly smart TV with portability in mind, the Cello ZRTG0242 is a solid option that offers good value for money.

Size Options

The Cello ZRTG0242 Traveller 12 Volt 24″ Smart Android TV is specifically designed for those who prioritize portability and compactness. Its 24″ size makes it ideal for travelers or use in small spaces where a larger TV may be impractical. The smaller size also ensures that the TV is lightweight and easy to carry, allowing you to take it on camping trips, RV adventures or move it around the house quickly. While the size may not be suitable for those seeking a larger screen for immersive viewing, its compact form offers convenience and versatility.

4K Resolution

The Cello ZRTG0242 Traveller 12 Volt 24″ Smart Android TV features a high-definition (HD) resolution, which offers a sharp and detailed picture quality. With 4K resolution, the TV delivers four times the number of pixels compared to standard HD TVs, resulting in enhanced clarity and fine detail. This allows you to enjoy a more immersive viewing experience, particularly when watching high-quality content such as 4K movies, sports events, or gaming. The 4K resolution ensures that the visuals on the screen are crisp and lifelike, providing a satisfying level of detail.

8K Resolution

It’s important to note that the Cello ZRTG0242 Traveller 12 Volt 24″ Smart Android TV does not support 8K resolution. As a smaller-sized TV, it focuses on providing a compact and portable solution rather than catering to the demands of ultra-high-resolution content. While 8K resolution offers an even more immersive and detailed viewing experience than 4K, it is typically found in larger-sized TVs and may not be necessary for smaller screens.

HDR Technology

HDR (High Dynamic Range) technology is designed to enhance the contrast and color accuracy of the TV’s display, resulting in more realistic and vibrant picture quality. Unfortunately, the Cello ZRTG0242 does not support HDR technology. While HDR can significantly improve the visual experience, especially when paired with compatible content, the absence of HDR support does not necessarily diminish the TV’s overall performance as a compact and portable TV in its intended use case.

OLED Technology

OLED (Organic Light-Emitting Diode) technology delivers deep blacks, vibrant colors, and excellent contrast ratios. However, the Cello ZRTG0242 does not incorporate OLED technology. OLED panels are typically found in higher-end TVs and are less common in smaller-sized TVs. While the absence of OLED technology means that the TV may achieve a different level of contrast and color accuracy than OLED-equipped TVs, it still delivers a satisfactory picture quality for its intended purpose.

MicroLED Technology

MicroLED technology represents the latest innovation in display technology, offering impressive picture quality and performance. However, the Cello ZRTG0242 does not utilize MicroLED technology. MicroLED displays consist of millions of tiny self-emitting LEDs, resulting in excellent color accuracy, brightness, and contrast. As a smaller-sized and more affordable TV, it is expected to feature something other than this advanced technology. Nonetheless, the TV’s LED-backlit display still offers a satisfactory viewing experience within its size and price range.

QLED Technology

The Cello ZRTG0242 does not feature QLED (Quantum Dot LED) technology. QLED TVs utilize quantum dot technology to enhance color accuracy, brightness, and contrast, resulting in vivid and lifelike visuals. While QLED technology can elevate the overall picture quality, it is often found in larger-sized and higher-end TVs. The absence of QLED technology in the Cello ZRTG0242 does not significantly impact its performance as a compact and portable TV, as it still provides a satisfactory picture quality within its intended usage scenario.

Ambient Mode

The Cello ZRTG0242 Traveller 12 Volt 24″ Smart Android TV features an ambient mode that allows it to blend seamlessly into its surroundings when not in use. Ambient mode displays various customizable visuals, such as artwork, photos, or weather information, on the screen to create a more aesthetically pleasing and personalized environment. This feature adds versatility to the TV, allowing it to serve as a digital photo frame or a decorative element in your living space. With ambient mode, the TV becomes more than just a functional device and adds a touch of style to your home.

One Connect Box

The Cello ZRTG0242 does not come with a separate one connect box. The one-connect box is a feature commonly found in higher-end TVs, where all the connections and cables are consolidated into a separate box that can be hidden away, leaving only a single cable running to the TV itself. This provides a cleaner and more organized setup by reducing cable clutter. However, as the Cello ZRTG0242 is designed for portability and compactness, it does not incorporate a separate one-connect box. Instead, the TV features a standard set of input ports directly on it.


You can expect to find several accessories in the package when you purchase the Cello ZRTG0242 Traveller 12 Volt 24″ Smart Android TV. These typically include a remote control, batteries for the remote, a power cord, a user manual, and any necessary cables for connectivity, such as HDMI or AV cables. It is important to check the contents of the package upon delivery to ensure that all the necessary accessories are included and in good condition. Additionally, consider purchasing accessories such as a wall mount, external speakers, or a streaming device to enhance your TV viewing experience.


As with any technology, the future of the Cello ZRTG0242 Traveller 12 Volt 24″ Smart Android TV is subject to advancements and developments in the industry. While it may not incorporate the latest cutting-edge technologies, such as OLED or MicroLED, future iterations of the TV may see improvements in picture quality, smart features, and connectivity options. It is important to stay informed about updates and advancements in the TV industry to make informed decisions when considering a new TV purchase.
