Wireless or reversible charging is a technology that the phones of the last generations have applied and that allows them to become a wireless charging emitter. If we have Samsung Galaxy Buds we could charge them using our Samsung Galaxy S21, S21 Plus and S21 Ultra only with the process of induction of electrons of this type of charge,
For this process to be effective, both devices must have support for Qi technology. To carry out this type of charge, the device must have at least 30% battery and it must be taken into account that it is not a particularly fast charge but it will help you when you have tense moments in which you run out of battery..
