【1000nits High-Brightness for Clear Visibility】A busy Saturday street campaign starts downtown, where a brand ambassador puts on the 21.5" LCD advertising backpack and walks through crowded sidewalks promoting a new product. The 1000-nit high-brightness screen keeps videos, logos, and promotional messages bright and easy to see even in strong daylight, while the IPS panel provides a 178° wide viewing angle for people passing from different directions. Automatic brightness adjustment adapts the display to surrounding light, making a high-brightness advertising backpack for outdoor promotions a powerful way to get your message noticed on busy streets.【Interactive Touchscreen & Remote Content Management】As people stop to check out the promotion, the responsive touchscreen turns a simple ad into an interactive experience. Customers can browse product information, watch videos, or explore campaign content directly on the display, while dual 8Ω 5W speakers add sound to the presentation. Behind the scenes, the built-in CMS lets the marketing team update content remotely through Wi-Fi without stopping the campaign. USB drives, TF cards, smartphone casting, Bluetooth, app installation, split-screen display, and scheduled playback provide even more flexibility for an interactive advertising backpack for product launches and promotional events.【Waterproof, Durable & Stylish Design】The promotion continues outdoors even when the weather changes. An IP65-rated enclosure helps protect the LCD screen against water and dust, while adjustable shoulder straps and a thickened handle make it easier to carry throughout the day. A built-in password lock adds extra security when moving between locations. From sidewalks to outdoor festivals, a durable advertising backpack for walking ads keeps promotional content moving wherever the crowd goes.【Long Battery Life – Up to 8 Hours Continuous Use】By afternoon, the campaign moves to a busy trade show where the team needs the display to keep running without staying near a power outlet. A high-capacity lithium battery provides approximately 5–8 hours of continuous use on a single charge, and additional batteries can extend operating time for longer campaigns. With a display lifespan of up to 60,000 hours, this long battery life advertising backpack for trade shows and all-day events is built for repeated commercial advertising use.【Versatile for Any Application 】When evening arrives, the same backpack moves from the trade show to a crowded concert promotion. Videos, images, text, slides, and promotional offers can all be displayed depending on the campaign. Use it as a portable advertising backpack for city street marketing, a digital signage backpack for trade show promotions, or a walking advertising display for concerts and rental businesses. Instead of keeping an advertisement in one fixed location, your message moves with your staff and reaches customers wherever the action is.【Why Choose Us】From a morning product launch on a busy sidewalk to an afternoon trade show and an evening event, Pyimgus brings high brightness, touchscreen interaction, remote CMS management, IP65 protection, portable battery power, and flexible content playback together in one mobile advertising solution.
