    Xiaomi Unveils 50W Car Wireless Charger for 299 Yuan ($42)

    Xiaomi has introduced its 50W Car Wireless Charger Kit, now available for purchase on Xiaomi Youpin for 299 Yuan, approximately $42.

    Specifications and Features of the Xiaomi 50W Car Wireless Charger Kit

    This high-powered 50W wireless charger by Xiaomi supports two input configurations:

    • Input 1: (DC-jack) 12-24V 8A MAX
    • Input 2: (USB-C) 5-20V 3.25A MAX

    As indicated by the product’s name, it delivers a maximum output of 50W. It is specifically designed to be compatible with all Xiaomi smartphones that support 50W wireless charging, including the Xiaomi 14 Ultra.

    The official details highlight the charger’s intelligent charging adjustment feature, ensuring compatibility with a variety of mainstream devices. It includes an indicator that conveniently displays the charging status.

    Design and Functionality

    The charger is equipped with an air duct designed for heat dissipation, ensuring it maintains efficient charging speeds even during travel.

    It offers multiple installation options, including a universal hook, fixed clip, and adhesive base, allowing users to select the most suitable method based on their car model and personal needs. Additionally, the charger features a built-in infrared light sensor and an electric clamp arm that automatically adjusts based on sensor data. Thanks to a built-in supercapacitor, the clamp arm remains operational for up to 30 minutes after a power outage, even when the device is turned off.

    Safety and Dimensions

    The charger is equipped with protections against overvoltage, undervoltage, overtemperature, and reverse connection. For those interested in its size, the dimensions are 116 x 72.5 x 58mm, and it weighs 183.3g.

    iPhone 16 Battery: Metal Casing, Higher Capacity, New Tech

    Tipster Majin Bu on X has shared some images of the iPhone 16’s battery pack. Surprisingly, the battery now has a metal casing instead of the usual soft foil packaging. Although it initially looks like dummy units, a closer inspection shows it to be an actual battery, with an additional metal casing on top of the plastic foil packaging.

    The metal casing will reportedly improve the heat dissipation

    The battery pack retains its familiar shape but now boasts a higher 3,597mAh capacity compared to the iPhone 15’s 3349 mAh. The battery capacity is engraved on the metal surface.

    While the exact reason behind Apple’s shift back to a hard casing design is unclear, reports suggest it could be aimed at improving heat dissipation. The iPhone 15 series did suffer from overheating issues post-launch. Though subsequent software updates have largely resolved this for most users, this change in the battery could further enhance heat management.

    Inside the metal casing could be a different battery tech

    The iPhone 13 Pro Max and 14 Pro Max weigh a hefty 240 grams, which is heavier than the book-style foldable Honor Magic V2 (231g). Last year, Apple replaced the stainless steel middle frame with titanium, making the iPhone 15 Pro Max 19 grams lighter than its predecessor.

    The extra metal casing for the battery will make the iPhone 16 heavier than the 171-gram iPhone 15. The higher battery capacity is also expected to contribute to the device’s weight.

    Additionally, the use of a metal casing occupies significant internal space, which was one of the major reasons smartphone makers switched to thinner plastic foil packaging. The soft packaging is also safer as it allows gas to expand and exit the battery pack easily in case of an accident, minimizing risk to the user.

    That said, there might be new battery technology inside that necessitates a hard casing but doesn’t carry the same explosion risk. It might also offer a higher energy density; otherwise, the phone would have to become thicker to accommodate the 3597mAh metal-encased battery. For example, the vivo X Fold3 Pro houses a 5700mAh battery (the largest battery in a foldable) using relatively new Silicon carbide (Si/C) composite material.
