Description
The Zkong Essence Series is a family of colorful electronic shelf labels, presented by Zkong as digital price displays for retail. The main design idea is detail: the page says these screens can show product descriptions, nutritional information, pricing variations and promotional offers in color.
The series covers six models, from the 4.0 inch ZKC40E badge to the 31.5 inch ZKC315E panel, with 7.3 inch and 13.3 inch sizes in between. The page describes remote, simultaneous price and promotion updates across multiple tags.
Color for detailed product information
Zkong positions the series for environments that need a clear, accurate display of product details. Smaller models suit badges and shelf tags, while the large-size versions suit poster displays and promotion notices. The page also describes customizable templates for branding and themed displays.
Display and wireless
The three datasheets (ZKC40E, ZKC73B and ZKC133E) list an EPD screen with a viewing angle of nearly 180º, 2.4-2.485GHz wireless and 128-bit AES encryption with OTA updates. The ZKC73B and ZKC133E list BLE 5.4, and the ZKC40E lists BLE 5.1.
Power, temperature and compliance
The ZKC40E has a 350mAh battery charged over Type-C, and its datasheet lists a vibration alert. The ZKC73B uses four CR2450 cells (2400mAh), rated up to 10 years at 2 updates per day.

All three datasheets list an operating temperature of 0~40℃ and CE, ROHS and FCC certification; the ZKC40E also lists SRRC.
