Charger cables have invaded our daily lives. They hang out on our desks, in our bedrooms, in the living room in short they are everywhere. To put this in order, why not opt for an induction charger. Today there are solutions compatible with all Android mobiles for a few tens of euros..
Wireless charger
The wireless charging (induction) did not start yesterday. In 1917, electrical engineer Nikola Tesla was already interested in wireless power transmission. Besides, if you have an electric brush or a hob of the latest generation, you are unknowingly using a magnetic induction recharging system.
Unfortunately this technology remains today limited to certain types of products. Few mobile phones offer wireless charging systems. And yet induction has many advantages..
For example, you no longer have to run after your charger or pay attention to the direction in which you introduce the charging cable (micro-usb or mini-usb sockets). Just put your smartphone on the wireless charger and that's it. Electric charging will start automatically without any intervention on your part.
Are all smartphones compatible with induction chargers?
This is the big problem. Few manufacturers are making the effort today to integrate a wireless charging device into their mobile phones. 
Consequence it is practically impossible today to get rid of its good old wired USB charger..
To find out if your smartphone is compatible with this technology, we have established a non-exhaustive list of devices supporting wireless charging by magnetic waves (IQ).
- Samsung Galaxy S9 / S9 Plus
- Samsung Galaxy S8 / S8 Plus
- Samsung Galaxy S7 / Edge / Edge Plus
- Samsung Galaxy S6 / Edge / Edge Plus
- Sony Xperia Z3
- Nokia Lumia 930
- Google Nexus 7
- Google Nexus 5
- LG G3
- LG G4
- HTC 8X
If your phone does not appear in the list do not panic. By equipping your smartphone with a specific wireless receiver, you too can take advantage of wireless charging and thus avoid the proliferation of cables in your interior.
Please note, however, the induction charge has some disadvantages. In general, a wireless charger is twice as slow as the latest generation fast chargers. Induction offers a lower efficiency than wired technologies.
