Is wireless charging safe?

As safe as your cooking plate

Did you ever doubt the safety of your cooking plate? You can compare wireless charging to inductive cooking, which is basically the same technology. This utilizes much more power (~5000W) than current wireless charging stations (~5-15W). Wireless charging systems must obey a set of rules and regulations related to electromagnetic interference (EMI/EMC), sometimes also called “radio disturbance”, and magnetic fields. All Zens products meet these rules and regulations and are Qi certified. All kinds of precautions have been taken to make sure that wireless charging is safe.

Qi certified

Qi sets the standard for safety when it comes to wireless chargers. All Zens wireless chargers have the latest technology and safety standards. So you can always safely charge your device.

Using chargers that are not Qi certified can heavily damage your battery or devices.

Foreign Object Detection (FOD)

Foreign Object Detection (FOD) is an embedded safety mechanism that automatically stops charging if there is interference caused by a foreign object such as metal (e.g. coins, paperclips, bankcards). The transmitter of a wireless charging system can detect if a piece of metal is located on its surface. In this case, the transmitter either does not start charging at all or it stops charging.

Heat protection

Wireless chargers are creating some heat as they are charging. This is absolutely normal and nothing to worry about. When using a regular wall charger, you’ll notice that the charger warms up a little. It’s the same with wireless charging.

All Zens chargers even have extra safety measures. When the charger is becoming too hot it will stop charging automatically to protect you and your devices.

Frequently asked questions

    No. It’s normal for your phone to get slightly warm when charging wirelessly, so this is nothing to worry about. All Zens products have passed appropriate safety tests. When using a regular plug-in charger, you’ll notice that the charger warms up a little. It’s the same with wireless charging.

    It might be. Wireless chargers must obey several safety measures. Wireless chargers that are not Qi-certified may not have implemented all mandatory and necessary safety features. As such, they may get hot and damage phones or other products placed on the charger. For example, a metal coin might, if the detection metal objects does not work properly, get very hot and even cause skin burn.

    The charger does not start charging. The transmitter of a wireless charging system can detect if a piece of metal is located on its surface (foreign object detection). In this case, the transmitter either does not start charging at all or it stops charging.

    Products using the Qi standard must be tested rigorously to help ensure safety, interoperability and energy efficiency. Only products that have passed these independent laboratory tests can use the Qi logo and are considered “Qi-certified”.
