In 2021, the USB-IF Association introduced a new standard for USB PD3.1 fast charging, which expands the maximum power of the USB-C universal interface from 100W (20V5A) to up to 240W (48V5A). Apple has taken the lead by using the PD3.1 fast charging protocol on the MacBook Pro 16", which can get up to 140W (28V5A) of power, which is better than the traditional 100W.
Focusing on the fast charging business, "CUKTECH" was formerly known as Jiangsu Zimi Electronics "ZMI", a wholly-owned subsidiary of Xiaomi, and has a long history of research and development of high-performance fast charging products, and a few months ago it released the No. 20 super energy column and No. 30 super energy warehouse that support PD3.1, all of which belong to the mobile power supply category. In December 2023, the PD3.1-supporting charger was long overdue, and Coolstate launched the first 140W charger in the digital series, joining the PD3.1 ecosystem family and contributing to the PD3.1 market.
The detailed model of the 140W charger is AD1404U, the body is made of a silver-gray bottom shell and a black shell, and the transition position is isolated by a family-oriented pulse blue as an embellishment, which is both fashionable and full of technology, which is also the classic ID of the Kustateke fast charging family. The input is designed with folding pins for portable travel, and supports a wide range of voltage of 110-240~50/60Hz, which can be used for cross-regional travel.
3C1A four-port configuration, multiple devices can also be done at one time
In terms of interface configuration, the 140W charger has four output ports with a specification of 3C1A, and more USB-C ports can better adapt to the use of mainstream consumer electronics. The blue USB-C1/C2 ports all support the new PD3.1 fast charging standard, and you can get up to 140W fast charging output when using one of them alone. USB-C3/A1 supports 33W multi-protocol fast charging output. In terms of multi-device charging, it supports power configuration strategies such as 100W+33W, 65W+45W, 45W+33W+33W, and supports up to four devices charging at the same time.
It supports the new PD3.1 fast charging standard and charges MacBook Pro at full power at 140W
This charger comes with the 28V5A extended voltage range that is essential for PD3.1 and can be used with MacBook Pro 16" to provide full power charging. At the same time, it is also backward compatible with the common PD3.0 fast charging standard, and the USB-C1 and USB-C2 ports both contain 20V5A / 15V3A / 12V3A / 9V3A / 5V3A / 5V3A voltage subsets, and support 5-11V5A / 5-20V3A two sets of PPS voltage subsets.
Excellent compatibility, Xiaomi private protocol, PPS, and integrated fast charging are all available
As a cool company that has a close relationship with Xiaomi, it also has an inherent advantage in the private protocol of Xiaomi mobile phones, USB-C1/C2 both support mi TurboCharge 120W private protocol, and it only takes 18 minutes to fully charge the Xiaomi 14 Pro. On the other hand, Adapt Charge, which is self-developed by Coolstate, has good compatibility with mainstream devices on the market, supports PPS, PD, QC, AFC, FCP and other fast charging protocols, and can meet the needs of Huawei, Samsung, Apple, OPPO, vivo and other brand mobile phones, laptops, tablets, smart bracelets and other devices.
In addition, the USB-A port of the 140W charger also supports the China-led converged fast charging protocol, providing 33W converged fast charging output, which can better provide cross-brand fast charging services for Android phones.
GaN+PFC+LLC advanced architecture, multi-port charger can also take into account both size and performance
The CoolState 140W charger uses a high-efficiency third-generation gallium nitride chip and an advanced PFC+LLC architecture to condense this four-port high-performance charger into a 100-watt single-port charger. The measured measurements are 79.38*65.04*32.18mm, and the volume is about 166.14cm³, which is only 80% of Apple's 140W single-port charger with more output interfaces, and its power density is 0.84W/cm³.
Stable output under full load for a long time, can be used as a laptop power adapter
The original design of the 140W charger is to operate stably with high power for a long time, and has been fully considered in terms of heat dissipation. The internal high-density thermal conductive adhesive filling process ensures a long-lasting full power output without derating, and can be used as a notebook adapter for a long time with full load. Built-in 9 safety protections such as over-temperature, over-voltage, and over-current, and NTC anti-surge protection effectively reduce the risk of safety problems caused by ignition of the charger. 360,000 times per hour for safe use at all times.
In terms of durability, Cooltech has "baked" it, passing 10,000 folding foot tests, 5,000 unplugging tests for USB-A interfaces, and 10,000 unplugging tests for USB-C interfaces to ensure long-term durability.
Summary of the charging head network
The launch of the 140W charger has made up for the shortcomings of the original PD3.1 fast charging family, which only has a mobile power supply category, and many users who love Coolstate are waiting for the launch of this product, and today it is finally here.
There are a total of four ports on the 3C1A, and up to four devices can be charged at the same time. Among them, the C1/C2 supports power blind plugging, and one of them supports PD3.1 140W fast charging output, MacBook Pro 16" can be fully powered and fully supported, and at the same time, C1/C2 also supports Xiaomi's 120W private fast charging protocol, so Xiaomi mobile phone users can directly enjoy a fast charging experience with full performance.
Compared with the common high-performance chargers on the market, the 140W charger is built with long-lasting and high power in mind, using a high-efficiency GaN+PFC+LLC architecture, and the internal glue is poured to strengthen the thermal conductivity, which can be used as a notebook power adapter at full power for a long time.
The 140W charger will be available for pre-sale from 10 a.m. on December 26 to 24 p.m. on the 31st, with a limited price of 199 yuan for the first time, and a daily price of 249 yuan, with a 1.5m length of 240W 6A data cable in the package, and interested partners can get on the car by themselves.
