Wireless charging technology has been around since the late years of the 20th century. Big names in the portable devices industry have adopted this technology. The latest ones are Apple and Samsung in their most recent flagship projects.
What is wireless charging and how does it work?
It involves electromagnetic fields that transfer energy from the charger to receivers that convert it into electricity to charge the battery. The devices have inbuilt receiver systems or external case receivers. The device charges at proximity and appropriate aligning on the charger, without cable connections to it.
Normal cable charging proves to have the upper hand in this one. However, they are to some extent countered with more advanced wireless charging systems that cost fortunes. Charging speeds vary depending on their output ratings where the most common ratings are 5A and 10A.
High production costs necessitate this technology to be found mostly in high-end gadgets. Low-cost phone users are, therefore, excluded from this technology. Institutions and companies are incorporating it into their premises for client use.
When cable charging, you are bound to move around within a radius. What about wireless systems? Some wireless systems are fixed into surfaces. Neither can you move around with the system nor have your device without properly aligning and proximity. However, battery experts advise on not using devices when charging them to maintain battery life.
The battery heats up slightly during charging even with a cable. Wireless charging will heat batteries more. Heated cells have a reduced lifespan. However, the difference is negligible.
It is only a matter of time before this technology becomes widespread. The adoption rate is massive and with projections at 4 billion receiver units to be shipped by 2020 only the sky is the limit.
