In the sweltering summer of 2023, the fire alarm of a high - end office building in Shanghai pierced the night sky. Surveillance footage showed that a regular power bank, which was charging at that moment, suddenly emitted white smoke. In just a few seconds, it exploded into a ball of fire, setting the entire desk ablaze. This experimental video released by a third - party testing agency quickly went viral across the internet—it was already the 17th power bank spontaneous combustion accident of that year. The comment sections were inundated with fear: “I sleep with a power bank next to my pillow every day,” “A power bank that suddenly gets hot on the subway is like a ticking time bomb”...
The anxiety over safety was gradually eroding consumers' last bit of trust in mobile power supplies.
Chapter 1 Epiphany in the Flames
“We must transform safety from ‘passive protection’ to ‘active visibility’!” Late at night in Shenzhen Science Park, Lao Zhao, an engineer from Kaiconn, wrote this note emphatically under the accident video. His team had just gone through a recall incident of a certain brand's power bank. As a technical consultant, he knew the industry's pain points better than anyone: 99% of power banks rely solely on internal chips for temperature monitoring, and by the time users detect a dangerous situation, it is often too late.
One day in the laboratory, an intern named Xiao Lu accidentally dropped an e - book. Even under strong light, the text on the e - ink screen remained clearly visible. “What if we could display the battery temperature on the surface just like text?” Lin Wei picked up an e - ink screen sample and stuck it onto the power bank casing. At that moment, the technical approach of “temperature visualization” became crystal clear.
Chapter 2 The Safety Revolution within the E Ink Screen
Traditional solutions faced three major challenges:
LED screens consume high power, and continuous temperature display would reduce the battery life by 30%.
There is a delay in mobile phone linkage, with Bluetooth alarms taking an average of 8 seconds.
Users have weak perception, and 90% of people tend to ignore mobile phone push notifications.
The Kaiconn team creatively embedded a 3.87 - inch four - color E Ink screen into the power bank. While competitors were still using obscure indicator lights, the E Ink screen of the AI power bank was building a safety line with intuitive color language: green for normal, orange for warning, and red for danger. Laboratory tests showed that this visual warning was 3.2 seconds faster than mobile phone alarms—and this 3.2 - second margin was precisely the critical window to prevent thermal runaway.

Chapter 3 The Intelligent Evolution Beyond Safety
At the product definition meeting, the marketing director, Mr. Sun, presented the results of user research: “Consumers want power banks to transform into mobile intelligent terminals.” The team decided to use the E Ink screen as a canvas to create a three - layer experience:
Safety Foundation
Military - grade explosion - proof battery cells combined with dual temperature sensors, with an error margin of less than 0.5℃.
When a high - temperature alarm is triggered, it broadcasts its location to all Apple devices within a 50 - meter radius through Find My.
Scene Intelligence
It calls on the cloud - based AI model (text - to - image) to generate 480*800 - pixel images, which are compressed and transmitted to the E Ink screen, automatically switching to an electronic photo album carousel mode.
It can generate landscape sketches during travels, display inspiration charts in meetings, and transform into a family photo wall at home—the E Ink screen seamlessly changes its role with zero power consumption.
Human - Machine Symbiosis
The magnetic stand can be adjusted at an angle accurate to 1°, enabling seamless switching between the “support mode” and the “photo frame mode.” In a test on the Beijing subway, 78% of passengers noticed the temperature display on their neighbors' power banks and adjusted the placement positions on their own initiative.

Chapter 4 The Debut of the AI Power Bank
At the 2025 CES exhibition, the AI power bank made its first appearance, attracting widespread attention. Exhibitors marveled at three “firsts”:
It was the first to achieve naked - eye visualization of safety parameters.
It was the first to integrate offline AI image generation into a mobile power supply.
It was the first to incorporate the power bank into the Find My anti - loss network.
“Safety should have always been this obvious.”

Epilogue Lighting Up the Future
Today, when tourists rent power banks, the E Ink screens display real - time temperature, local scenic sketches, and multilingual safety tips. In Tokyo Disney, it has even become a “positioning beacon” for children to find their parents.
“We haven't just changed the way of charging,” Lao Zhao said, gently caressing the E Ink screen components on the patent wall. “We've made technological risks readable, preventable, and controllable.” That clear E Ink display is writing a new paradigm for mobile safety—because true intelligence never requires users to close their eyes and pray for luck.
