Magnetic Wireless Power Bank, 15W Ultra-Fast Portable Charger(iPhone 15/14/13/12/11/X), 5000mAh, PD 20W(Dark Gray)

The wireless charging technology operates on the principle of electromagnetic induction. During the electromagnetic conversion process, there is an energy loss in the form of heat release, resulting in a heat phenomenon associated with wireless charging. The on-board conversion rate of the product exceeds 94.5%, while the wireless conversion rate is over 84%. When using wired charging, the efficiency is higher (>93%), compared to wireless charging (>76%), which is a normal occurrence.

In the product development phase, the company visited many customers and compared several excellent similar products. Based on the analysis of advantages and disadvantages, they developed several technologies to enhance the product: unified input/output interface technology, adaptive voltage technology, and adaptive wireless adaptation technology. These technologies are intended to provide users with a differentiated experience. The company welcomes any new technical ideas from customers and would be grateful for the feedback.

The product utilizes an aluminum alloy body, which has both advantages and disadvantages. In wired discharge scenarios, the aluminum body offers a better experience compared to plastic shells, as it prevents scratches and provides a more premium feel. However, in wireless discharge mode, the higher thermal conductivity of metal results in a warmer surface compared to plastic, although the product has temperature control protection that triggers at 48°C. Additionally, the tempered glass cover showcases the product's design well and provides a premium feel, but it is more susceptible to damage than plastic. Users are advised to avoid intentionally striking the tempered glass cover.

The product has passed various mandatory certifications, such as FCC, CE, RoHS, SRRC, and CCC, ensuring its safe and reliable use.

The product design primarily focused on technical aspects, aiming for simplicity and practicality. While some aesthetic considerations were made, there is still room for improvement in terms of visual appeal compared to other products in the market. The company aims to address both technical and aesthetic aspects in future iterations.

Key features of the product include: 1. Smart-IO unified interface technology: The power bank has a single Type-C port for both charging and discharging, simplifying the user experience. 2. Intelligent recognition technology (SmartQi & VOL-adapt): The power bank automatically adapts to the connected devices, supporting up to 20W wired and 15W wireless charging. 3. Omni-directional protection technology: The product has undergone rigorous testing and incorporates various safety measures, including overcharge, overcurrent, short-circuit, and temperature control protection. 4. Compact and portable design: The power bank's dimensions of 93mm x 64mm x 11mm make it easy to carry during travel and outdoor activities. 5. Material and design considerations: The aluminum alloy body provides durability and better heat dissipation, while the tempered glass cover offers a premium look but requires caution to avoid damage.

The company values customer feedback and welcomes suggestions for improvements. Users are encouraged to contact the company through the provided channels.
