BB-LED-15.6 inch WiFi — 15.6-inch LED Backpack Screen
The BB-LED-15.6 inch WiFi is a wearable LED billboard: a 41 × 33 × 14 cm backpack with a 15.6-inch full-colour LED panel on the back, controlled over WiFi from a phone app. Content is drawn or uploaded in the app and pushed to the bag, so a promoter, a mascot or a commuter can change the message in seconds. It runs from any USB power bank and the shell is waterproof, wipe-clean fabric.
Key Features
- WiFi control: the panel connects over WiFi and is driven from the app — draw text, pixel art, GIFs or animations and push them in seconds, no cable and no PC.
- 15.6-inch LED panel: large enough to read across a room or a street, small enough to stay a wearable backpack rather than a rig.
- 41 × 33 × 14 cm daypack: a real bag with real capacity — laptop, documents and daily essentials fit alongside the screen hardware.
- USB power bank operation: the panel runs from any standard USB power bank through the external USB port, so runtime is whatever cell you carry.
- Waterproof fabric: splash-resistant, wipe-clean shell — commuting in the rain does not end the display.
- Comfortable structure: honeycomb breathable, shock-absorbing back panel and ergonomic shoulder straps for all-day wear.
- Instant campaign change: one bag can run a different message every hour, which is what makes it useful for promoters, mascots and street teams.

FAQ
Q: What is the BB-LED-15.6 inch WiFi?
A: It is a 15.6-inch full-colour LED panel built into a 41 × 33 × 14 cm backpack. The panel is controlled over WiFi from a mobile app, so the wearer becomes a walking billboard that can change its message at any moment.
Q: How do I upload content?
A: Through the mobile app: connect the bag’s controller over WiFi, then draw text, pixel art or animations, or upload images and GIFs, and push them to the panel. No cable and no computer are needed after the first setup.
Q: How long does the battery last?
A: The panel is powered from a USB power bank through the external USB port, and runtime is whatever the bank provides — a 10,000 mAh bank covers a typical event shift. The power bank is not included because most customers already carry one.
Q: Is it waterproof?
A: The shell is waterproof, wipe-clean fabric, so rain and spilled drinks are not a problem. The electronics sit behind a sealed panel; we still recommend not submerging the bag or leaving it in heavy rain for hours.
Q: What is the difference between the WiFi and Bluetooth versions?
A: The WiFi version connects to the app over a WiFi link, which gives a longer range and lets several bags be managed from one phone; the Bluetooth version pairs directly and is simpler to set up for a single wearer. Both drive the same 15.6-inch panel.
