Fast charging or normal charging?
There are various types of chargers. The main difference is the output indicated in W. The common wireless outputs are 5W, 10W and 15W. Most mobile devices support 5W charging but the newest generation support 7.5/10W. The higher the W the faster your phone will charge. When using a fast charger your phone will indicate on the screen it’s enabled for fast charging.
Suitable or not?
With a wireless charger you charge your smartphone via a Qi standard, your smartphone should have this Qi standard. The most common smartphones that are suitable for wireless chargers include Apple iPhone 8 and iPhone X, like the Samsung Galaxy S8 and Galaxy Note 8. In addition, it is important to look at the number of ampere. Some chargers are too powerful for smartphones, which are making them incompatible.
