Addressing Everyday Mobile Battery Challenges
Many users seek a mobile battery with substantial capacity and fast charging capabilities, yet find heavy devices inconvenient for daily carry. This product aims to address these concerns by balancing specifications with portability, providing a solution for those who desire both high performance and ease of use in their daily lives.
Digital devices such as smartphones, wireless earphones, tablets, and notebook PCs are increasingly carried daily. Consequently, mobile batteries are now required to offer more than just capacity, with demand for improved charging speed, portability, and ease of use. This new mobile battery was developed to meet these evolving needs.
What is a Semi-Solid Battery?
The product incorporates a “semi-solid battery,” which significantly reduces the liquid electrolyte content. This technology allows for enhanced performance required in modern mobile batteries. Furthermore, it is designed for approximately 2000 charge-discharge cycles, aiming for durability for repeated daily use. It is important to note that actual cycle life may vary depending on usage environment and charging/discharging conditions.
Semi-solid batteries offer several advantages over conventional lithium-ion batteries, including improved reliability, enhanced rapid charging capabilities with reduced heat generation, better performance in various temperature conditions, longer lifespan, and stable output performance over extended periods.
Six Key Features of the New Mobile Battery
1. Semi-Solid Battery Adoption
This product utilizes a semi-solid battery with approximately 5% liquid electrolyte content. This advanced battery technology aims to deliver the performance demanded by the next generation of mobile batteries.
2. 10000mAh Capacity at Approximately 190g
For a device carried daily, weight is as crucial as capacity. Despite its 10000mAh capacity, this mobile battery weighs approximately 190g, making it highly portable for commuting, school, travel, and business trips where minimizing luggage is desired.
3. Supports Max 45W USB PD Fast Charging
The USB Type-C ports support up to 45W output, enabling rapid charging for compatible smartphones and tablets. This feature is particularly useful for quick top-ups before heading out or during short transit times. It also supports PPS (Programmable Power Supply). Charging speed and output may vary depending on the connected device, cable, and charging conditions.
4. Three Ports: USB Type-C x2 + USB Type-A x1
The battery is equipped with two USB Type-C ports and one USB Type-A port, accommodating both USB Type-C compatible devices and existing USB Type-A cables. This makes it convenient for users carrying multiple devices like smartphones and wireless earphones.
5. Digital Battery Level Display
To prevent unexpected power depletion, the device features a digital display that shows the exact battery percentage. This allows users to easily determine when to recharge before going out.
6. Heat Suppression Function
A heat suppression function is integrated to manage the internal temperature during charging. This feature helps maintain product quality and ensures comfortable long-term use by gradually reducing output power if the internal temperature rises, protecting the battery from high temperatures.
The Ideal Companion for Gadget Users
While mobile batteries are becoming larger in capacity and output, this often leads to increased size and weight. Conversely, prioritizing compactness can result in insufficient capacity or output. This product strikes a balance with:
-
10000mAh capacity
-
Max 45W output
-
Approx. 190g weight
-
3 ports
-
Digital battery level display
-
Semi-solid battery technology
It is designed to be an everyday companion for gadget users who carry not only smartphones but also multiple other digital devices.
Color Variations
The mobile battery is available in three colors:
-
Lilac Rose (PINK)
-
Sky Blue (BLUE)
-
Midnight Black (BLACK)
These color options were chosen not only for their functionality as a gadget but also to make them appealing everyday carry items.
