The Xiaomi 20W Wireless Fast Car Charger (model number GDS4127GL, also known as WCJ02ZM) promises a seamless blend of fast charging and convenient hands-free operation. I’ve been using this charger for several weeks in my car, putting it through its paces on various commutes and longer trips. This review will delve into its performance, features, and overall user experience.

This charger boasts several impressive features. The automatic clamping mechanism, activated by an infrared sensor, is surprisingly smooth and reliable. It securely holds my phone, even over rough roads. The 20W fast charging capability is a definite plus, noticeably quicker than my previous wireless charger. The dual cooling system, comprising a fan and metal bracket, keeps the charger and my phone from overheating, even during extended high-power charging sessions. The elegant design, featuring a 2.5D glass charging panel and a blue ring-shaped welcome light, adds a touch of sophistication to my car’s interior.

The 81.5mm clamp arm easily accommodates my larger phone (and even my wife’s iPhone XS Max!), giving it great versatility for a wide range of devices. Installation was straightforward, and the included adhesive stand provided a stable mounting base.

In terms of charging speed, the Xiaomi charger delivers on its promise. I consistently saw fast charging speeds, significantly reducing charging times compared to my previous 10W charger. The dual cooling system performs well, keeping both the charger and my phone cool to the touch even after extended use. The automatic clamping mechanism is reliable, though occasionally, I found it a tad slow to react. The multi-angle adjustment allows for comfortable viewing angles.

I tested the charger on various road conditions, from smooth highways to bumpy city streets. The grip remained secure throughout, never dropping my phone. The infrared sensor worked flawlessly, consistently recognizing and clamping onto my phone.

Pros:

• Fast 20W wireless charging
• Effective dual cooling system
• Reliable automatic clamping mechanism
• Widely compatible with various phone sizes
• Stylish and elegant design
• Easy installation

Cons:

• The clamping mechanism can be slightly slow at times.
• The adhesive stand might not be suitable for all dashboards.

Overall, the Xiaomi 20W Wireless Fast Car Charger (GDS4127GL) is a solid choice. Its combination of fast charging, reliable clamping, effective cooling, and stylish design makes it a valuable addition to any car. While the clamping mechanism’s occasional slow response is a minor drawback, it doesn’t significantly detract from the overall positive experience. I would highly recommend this charger to anyone looking for a convenient and efficient way to charge their wireless-charging-compatible phone on the go.
