Wireless Charging Safety

March 08,2019 -

1.Is wireless charging safe?

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 TOPTAI products meet these rules and regulations. So, is wireless power safe? Yes, all kinds of precautions have been taken to make sure that it is.

2.My phone feels a little warm to the touch after charging. Should I be concerned?
No. It’s normal for your phone to get slightly warm when charging wirelessly, so this is nothing to worry about. All TOPTAI 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.

3.What happens if I put a piece of metal on the charger?

 

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.
