In the era of smartphones being attached to all daily activities, the need for fast and convenient battery charging is increasingly concerned. High-capacity chargers such as 100W are being chosen by many people because of their ability to quickly charge energy, while also supporting simultaneous charging of many larger devices such as tablets or laptops.
Thanks to that, users do not need to carry too many chargers when traveling, both saving space and ensuring convenience. However, the question is: Is using a 100W charger for iPhone really safe?

In fact, the iPhone only receives the amount of power that is appropriate to the limit that the device supports. From the iPhone 8 onwards, Apple has equipped USB Power Delivery (USB-PD) technology to allow fast charging. However, the maximum power level that the iPhone can receive is only about 20–27W, depending on the device model. This means that when plugged into a 100W charger, the iPhone will automatically adjust and only take the necessary amount of power, there is absolutely no "overload".
There are many 100W charger options available for iPhones, including the Anker Prime 100W USB-C GaN ($84.99, 3 ports, 4.7 stars), the Anker iPhone Nano Charger, as compact as the AirPods Pro case ($44.99, 4.3 stars), and the UGREEN Nexode 100W 4-Port GaN ($54.99, 4 ports, 4.6 stars). These products not only support iPhones but are also compatible with many other devices such as iPads, MacBooks, Windows laptops, and even handheld game consoles, providing convenience and safety thanks to USB-C PD technology.

However, to ensure safety, users should pay attention to choosing 100W chargers from reputable brands. In addition to being USB-C PD certified, when choosing to buy a 100W charger for iPhone, users should also pay attention to whether the product is Apple MFi certified or not. This certification ensures that the accessory complies with the technical standards set by Apple, helping the charging process to be safe and stable. You can check if the manufacturer owns this certification using the MFi Licensed Accessories Search tool on Apple's official website.
In parallel, buying chargers from Apple-authorized retailers is also an important note. Avoid buying used products or from unknown third-party sellers to limit the risk of encountering counterfeit, poor-quality products that can affect the device and user safety.
If you’re still concerned about the quality of a 100W charger, you can consider alternatives like charging your iPhone via an iPad or using a power bank from a reputable brand. It’s also important to use a quality cable, as not all USB-C cables are fast-charging compliant, and poor quality cables can reduce efficiency or pose a risk to your device.
