Can I use a 12V power adapter if I lose the original one?

No, you must strictly use a 5V power adapter; plugging in a 12V adapter will instantly burn out the LED board and cause permanent damage.

Does this LED sign require an active internet connection to work?

No, the sign generates its own local WiFi hotspot that your phone connects to directly for updating the text via the app.

Can I display both English and Chinese characters on this board?

Yes, the smart app fully supports both English and Chinese text input, allowing for seamless bilingual advertising.

How do I power this sign if I want to use it outdoors at a market stall?

Because it uses a low-power 5V interface, you can simply plug it into a standard portable USB power bank for hours of outdoor use.

Can I see the different sizes in person before buying in Hong Kong?

Yes, you can visit our Sun Cheong Computer Co. Ltd. store in Sham Shui Po to view the 2-character to 12-character sizes in action before making a purchase.

Safe and Portable 5V Power System

This LED sign operates on an ultra-low 5V power supply, ensuring it generates minimal heat and remains completely safe to touch during long operating hours. Because it uses a standard 5V interface, you can easily power it using the included adapter or plug it directly into a portable power bank. This makes it an incredibly versatile advertising tool for mobile food trucks, weekend market stalls, or outdoor concert booths where traditional wall outlets are unavailable.

Multiple Sizes for Any Venue

We offer five distinct sizes ranging from a compact 2-character display to a massive 12-character banner to perfectly fit your storefront window or interior wall. The 2-character board (22x11.5cm) is ideal for small checkout counters, while the 12-character board (118x12cm) provides high-visibility marketing for large hotel lobbies or restaurant facades. Each lightweight panel is designed for effortless installation, allowing you to mount it quickly and start advertising immediately.

Pro Tip from Our Technicians

Always use the included 5V power adapter or a high-quality 5V power bank to operate this LED board. Our Sham Shui Po technical team strictly warns against plugging this device into a 12V or higher power source (such as a CCTV or router adapter), as excessive voltage will instantly burn out the LED matrix and permanently damage the control board.
