Qi wireless chargers

Frequently asked questions

Are Zens wireless chargers Qi-certified?

Yes. Zens is a proud member of the Wireless Power Consortium (WPC) since 2011 and all ZENS wireless chargers are Qi-certified.

How does wireless charging work?

Wireless charging works by something which is called magnetic induction. In inductive charging systems, energy is transferred between coils by a magnetic field via inductive coupling. Read more on how wireless charging works.

How many watts do I need?

How many watts you need mostly depends on what your phone or device can handle and when or how you want to use the charger. Do you want the fastest charger possible to fast charge your device? In most cases a 10W charger or 15W charger will suffice, as the maximum amount of Watts for fast charge is capped by smartphone manufacturers. For Apple Fast Charge this is 7,5W and for Samsung Fast Charge this is 9W. Make sure your phone actually support fast charge such as Apple Fast Charge or Samsung Fast Charge. If you want to charge your device at night, a 5W charger will also suffice.

Is it dangerous to use a wireless charger that is not Qi-certified?

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.

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 Zens products meet these rules and regulations and are Qi-certified. So, is wireless power safe? Yes, all kinds of precautions have been taken to make sure that our wireless chargers are perfectly safe. Always make sure that your wireless charger is Qi-compatible and Qi-certified. This way you can be sure that your wireless charger is safe for use.
