This semiconductor is indeed much more efficient than traditional silicon at equal size. Many manufacturers are therefore taking the opportunity to produce very powerful chargers while being much less bulky.

  • For an iPhone: 20 W USB-C Power Delivery charger  + USB-C to USB A lightning cable
  • To charge several devices at the same time: 4-port Power Delivery GaN 65 W charger

Understand everything to fast charging

Can fast charging damage my battery?

The batteries in our electronic devices are sensitive and charging them quickly can in theory damage them or shorten their lifespan. In practice, this is not really the case. Modern charging is indeed a complex affair, the power supplied by the charger is indeed modulated to limit the heating and wear of the cells. Thus, the first 80% of charge is very fast and then gradually slows down.

No need to be afraid, the phone and the charger take care of everything.

Does my battery need to be empty before charging?

This very common myth is nonetheless totally false. On the contrary, battery wear is most marked when it is completely empty. No need to run out of fuel before refueling.
