My Personal Experience With UGREEN 100W Gan Charger

As an avid technology enthusiast, I recently purchased the UGREEN 100W Gan Charger and had the opportunity to use it extensively. I must say that my experience with this charger was quite disappointing.

Firstly, one common issue that many users faced with this charger is its compatibility with certain devices. It appears that the charger is not suitable for “smart” charging devices like the M1 MacBooks. The charger constantly cycles when connected to these devices, causing interruptions in charging and potential damage to the laptop battery. This is a major drawback and should be taken into consideration before purchasing.

Another downside of this charger is its performance when multiple devices are connected via USB. Users have reported that power delivery becomes unstable in such cases, leading to erratic behavior and heating up of the charger. This can be a significant inconvenience if you rely on charging multiple devices simultaneously.

UGREEN 100W Gan Charger Ports

In terms of build quality, I have mixed feelings about this charger. On one hand, it feels very solid and well-built, which gives a sense of durability. However, this solidity comes at a cost – the charger is larger and heavier than expected. While these features may aid in heat dissipation, they make it less suitable for travel purposes as it takes up more space in your bag.

Now let’s talk about some positives of the UGREEN 100W Gan Charger. Firstly, when used with compatible devices, it does deliver fast charging speeds, especially for mobile devices like Samsung smartphones that support Super-Fast charging.

Additionally, some users appreciate the strong construction of this charger and find it reliable for their needs. It offers satisfactory performance for certain laptops or non-smart-charging devices without any issues.

In conclusion, based on my personal experience and considering the feedback from other users, I would not recommend the UGREEN 100W Gan Charger for several reasons: its lack of compatibility with “smart” charging devices like M1 MacBooks, unreliable power delivery when multiple devices are connected via USB ports, and its bulkiness making it less ideal for travel.
