About this item

  • The SMAHEAT 2.1-inch countdown clock provides a long-term countdown of over 999 days, 23 hours, 59 minutes, and 59 seconds, with 3 independent countdown group reminders (as of December 31, 2099), calendar display (month/day/year), and 12/24-hour clock mode. It is suitable for: event countdown, holiday timer, activity countdown, baby due date tracking, retirement countdown, office project management, and classroom exam timing.
  • Unlike traditional single group countdown clocks, this timer supports three independent countdown groups, each allowing for a long-term countdown of over 999 days, 23 hours, 59 meters, and 59 seconds (as of December 31, 2099). Set the calendar/time function to automatically calculate the countdown days and time between the current time and the set time. The buzzer will sound in stages: 1 minute before completion, the indicator light will flash, the buzzer will sound every 5 seconds, and the buzzer will sound continuously for the last 10 seconds to mark the completion of the countdown.
  • Larger size: 2.1-inch 9-digit LED numbers (3 blue+6 red), ensuring clear visibility from a distance indoors. It is equipped with 5 levels of brightness adjustment, making it easy to adjust the monitor brightness according to different lighting environments.
  • Extended lifespan: 2.1-inch high character ultra bright LED screen. The casing is made of aluminum alloy to enhance the durability of the clock, with dimensions of 19.49 inches x 3.54 inches x 1.34 inches. Supports wall mounted and desktop placement options. The product packaging includes a 100-240VAC input 12VDC output power adapter, as well as brackets and screw components for installation.

FAQ

What types of products does Stemora offer?


Stemora offers supplies for science experiments, microscopy, biology learning, measurement, laboratory organization, electronics, robotics, coding education, 3D printing, maker projects, and classroom activities. Available products and specifications may change over time.

Are Stemora products suitable for children?


Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.

Is adult supervision required?


Adult supervision is recommended for children and students, especially when using electrical components, sharp tools, heated equipment, glassware, small parts, or experiment materials. Customers are responsible for following all product instructions and safety precautions.

Can these products be used at home and in classrooms?


Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.

How can I check what is included with a product?


Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.

How do I know whether an electronic or robotics part is compatible?


Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.

When will I receive tracking information?


Tracking information is generally provided within 3–5 business days after an order is confirmed. In some cases, processing may take approximately 7–8 business days. Delivery may require an additional 4–5 business days after tracking becomes available, depending on the carrier and destination.

Why did my order arrive in separate packages?


Products in the same order may be shipped from different fulfillment locations. As a result, items may arrive separately and have different tracking numbers. You will not be charged additional shipping fees solely because an order is divided into multiple packages.

Can I change or cancel my order?

What should I do if an item arrives damaged, defective, or incorrect?
