THE QI LOGO
The Qi logo is a trademark of the Wireless Power Consortium. Compatible wireless chargers, compatible mobile phones, and other compatible mobile devices may license the Qi logo.
Qi is fully compatible, meaning that that any phone or other device carrying the Qi logo will work with any charging surface that carries the Qi logo, regardless of manufacturer or brand.
Only products that were tested by an independent test lab may carry the logo.
UNLICENSED USE OF THE QI LOGO
Unfortunately, the Qi logo is sometimes used on products that were not properly tested. Such a product may not work correctly. Typical failures of untested products are:
- a charger works with some phones and not all phones
- a phone can charge on some charger and on all chargers
- the phone becomes dangerously hot
- charging is frequently interrupted
