Wireless power, also referred to as wireless charging, is the way to go today and is a technology standard increasing yearly worldwide. People no longer must accept the traditional standard of being “tied down” by cords. From headphones to telephones, all things are becoming wireless.

Wireless power technology began in earnest this century and is in line to transform the world to become completely wireless. As of 2021, there are more than 10 billion active wireless connected devices.  Cellular phone adaption is leading this industry, charging wireless at home, at the office, at the airport, in restaurants in your car, and many other locations.

Who has the time to look for a charger or adapter to plug into a wall? It can be tedious to connect and plug in a charger to give a device that much-needed charge.

The good news is that wireless power technology is continuously evolving. This brief overview explains why and how this technology is on the rise and being implemented into more and more applications.

The Problem?

“The problem is that charging your device by plugging it in is growing obsolete for several reasons,” says Phil Shelton, a marketing blogger at Write my X and 1 Day 2 write. “One reason is that carrying around cords to charge your device is a tedious task in a fast-paced world. Another reason is that your device might not charge correctly using standard cords. Lastly, standard cables’ management might hurt your battery and limit battery functionality.


The Solution?

To tackle these problems, there has been a surgency in implementing wireless power solutions for an ever-growing array of applications. Wireless power solutions increase convenience, reliability, and battery management. In today’s world, wireless power solutions are being implemented increasingly in the automotive, aerospace, medical, manufacturing, and consumer electronics industries, to mention just a few, but the possibilities are enormous.

Types Of Wireless Charging

Now that you know the benefits of wireless power, here are some methods:

  • Inductive charging: Uses magnetic induction to transfer up to a few 10’s of watts over a few mm of distance. This technology has been adopted mainly in smartphones and accessories like smartwatches and ear pods.
  • Radio Frequency based charging: Uses radio frequency to transfer power over a few centimeters and up to a few meters. Due to safety and regulatory reasons, this technology is limited to sub <1W applications such as IoT devices and sensors.
  • Resonance charging: Like inductive charging, this is based on magnetic induction, but it operates on the resonance point, providing more spatial freedom and enabling charging up to a few centimeters. Due to the challenges of working at the resonances point resonances technologies have adopted communication-based on out-of-band communication such as Bluetooth and normally operated at 6.78MGz (examples: robots, electrical vehicles).
  • Powermat SmartInductive™ is a unique technology for any device and bridges the gap between magnetic induction and resonance, overcoming the industry challenges.

How Does Wireless Power Work?

Wireless power transfers energy using one of the methods above to charge a device’s battery. Based on magnetic induction, Powermat SmartInductive™ Technology provides a broader scope of capabilities than traditional magnetic induction solutions found in the market today. The unique Powermat SmartInductive™ approach offers a hybrid solution between inductive wireless charging and resonance, capturing the best of both worlds. Powermat SmartInductive™ provides more power, more freedom of positioning, longer ranges between wireless power transmitters & receivers, and lower implementation costs. Technology uses a unique in-band high quality modem to enable power control on and off the resonance point.

The electric energy is transferred from a transmitter that receives power from a common power source and transmits the electric energy via electromagnetic induction to a device’s receiver (located in the device).


“Wireless charging provides many advantages, especially in today’s world,” says Charlie Anderson, a business writer at Origin Writings and Brit Student. “First, wireless charging technology offers a secure way of charging battery-operated devices so that you can feel more confident where and when you charge. Plus, it eliminates the struggle of carrying many cords and adapters that can easily get lost. In addition, you don’t have to worry about the device overheating from charging from the traditional cord-and-outlet method, nor worry about any electrical failures that might arise. And it’s Qi-friendly, meaning that it can inductively charge across distances of up to 40mm.”

With that said, the following major smartphone manufacturers are utilizing wireless charging technology, and it is increasing across all companies, such as:

  • Apple
  • Huawei
  • LG
  • Motorola
  • Samsung, AND
  • Sony



As you can see, wireless power solutions are becoming the future of charging devices; as the world moves away from cords and plugs, wireless power innovations will continue to evolve.
