The risks of a non-Qi-certified wireless charger

The risks of a non-Qi-certified wireless charger
You may not even have heard of Qi very often, so why should you worry about it? Using non-Qi-certified chargers may be dangerous, because these wireless chargers may not meet the mandatory and necessary protection features.

Risk of injury

The Qi certification comprises Foreign Object Detection (FOD) measures. This means that for Qi certified products, the transmitter of the wireless charging system can detect it, for example, 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 once it detects it. If a wireless charger does not have FOD or if FOD does not work well, objects that are placed in close proximity to the wireless charger, or between the charger and the phone (e.g., phone case), may get very hot. This may cause serious injuries such as third degree skin burns.

Risk of device damage

The Qi specification includes measures that limit voltages wireless chargers induce in other mobile devices. A non-Qi-wireless charger that is not designed properly may induce high voltages inside mobile devices when they are placed in close proximity to the charger. These high voltages may cause damage to your device.
The Qi specification concerns thermal testing of wireless chargers. Also, it includes magnetic shielding of the battery to minimize heating of the battery and mobile phone. Overheated chargers damage the battery itself and shorten battery life. Temperatures reaching or exceeding 100 °C can potentially cause serious damages to the surfaces that are in contact with an uncertified wireless charger or an uncertified phone case. It may even cause your phone case to melt.

Risk of incompatibility

The idea behind Qi is that all Qi products are interoperable; any Qi certified mobile device works with any Qi certified wireless charger. Products that are not certified may be incompatible with other wireless charging products.Recognizing a Qi-certified product

How do you know if a product is really Qi-certified?

There are several indicators that you can use to find out whether you are dealing with a counterfeit product or an official Qi product.
    
  • Check whether the company is member of the Wireless Power Consortium (WPC) – only companies that are members of the WPC and signed the Qi logo license agreement can certify a product.
  • Always look for the Qi logo – the Qi logo can only be used legally for products that have Qi certification.
  • Pay attention to the Qi claim that is made – being ‘Qi-certified’ is the only official claim. Claims like ‘Qi compliant’, ‘Qi compatible’ or ‘works with Qi’ may indicate the product has not undergone official Qi certification testing.
  • Check the Qi certification database – all Qi certified products can be found in this database. A product is Qi-certified if you find a match for the brand name, product name, and type number.
