Wat is draadloos opladen en hoe werkt het?

Cables can be incredibly inconvenient. They always get tangled, break easily, and take up space. That's why more and more people are choosing wireless charging. Wireless charging, also known as Qi charging, is available with a growing number of devices. With wireless charging, you simply place your smartphone on a charger, and it starts charging automatically. You no longer need to plug in a cable. Phones with MagSafe or a magnetic case can also connect magnetically. Not every phone is Qi-compatible. Keep this in mind before purchasing a wireless charger or power bank.

How does wireless charging work?

Wireless charging works by means of two coils. On the one hand, the charging coil, which is connected to the wall socket or other power source. This coil creates a magnetic field. On the other hand, the receiving coil, which is in your phone, earphones or other device. When you place the receiving coil on the charging coil, current is transferred from device to device via a magnetic field.

For this, the device must lie exactly on the charger. For example, the device cannot be a centimeter away from the charger. MagSafe is incredibly useful, because of the strong magnet in your phone and in the charger, the phone always lies well on the charger. The more directly the coils lie on each other, the more efficiently your device charges.

What is Qi charging?

Qi is an official quality and compatibility standard for wireless charging. This means a few things:

  • The charger is protected against overheating, overvoltage and short circuit. This prevents damage to your device. The charger also recognizes whether a compatible device is on the charger. If this is not the case, the charger stops charging to prevent damage.
  • If a charger is Qi-certified and your device is too, you know it will work.
  • It minimizes energy loss and provides 60-75% efficiency.
  • Can provide power up to 15 Watts as long as your device supports it.

Benefits of wireless charging

  • No more cables needed when charging
  • No hassle with tangled cables
  • seats or incorrect connections
  • Simply place the device on the charger → charge immediately
  • No more cable breaks
  • No specific cable required per device (provided Qi support)
  • No wear and tear on ports of devices and chargers
  • Devices last longer

Disadvantages of wireless charging

  • Wireless charging is slower than wired charging (approx. 20W vs. 140W)
  • Takes longer to fully charge the device
  • Less efficient: more energy loss than with cable charging, example efficiency: cable approx. 85%, wireless 60–75%
  • With a wireless power bank you can charge your phone less often
    Coils must be properly aligned, otherwise lower efficiency or no operation
  • Increased heat generation from charger and device
  • Additional heat can shorten battery life (although this is limited with modern chargers)
  • Wireless chargers are often more expensive due to more complex technology
