Wireless Power
Wireless Power Transfer (WPT) is a device in which one can charge his cell phone without plugging it direct to a charger irrespective of the type of phone charger your phone uses. Now, you won’t have to be stressing yourself looking for phone chargers including your Laptops. Researchers have discovered a WPT technology that can charge mobile phones from a distance.

Who Discovered Wireless Phone Battery Charging

The wireless power transfer technology was discovered by researchers at the Korea Advanced Institute of Science and Technology (KAIST). It works the same way Wi-Fi and Hotspot works for Internet connections.

With the help of this technology, your device can get charged without being plugged to a charger. If you are within the selected space wherever the charging is  activated, is just like the Wi-Fi Power zone, the researchers aforesaid.
The system will charge multiple devices at the same time and in all directions up to 1/2 metre off from the facility supply. This is said by lead investigator faculty member Chun T. Rim. Rim’s team has with success showcased the technology on at a research laboratory on KAIST’s field.
All wireless phone battery charging technologies have had difficulties with the matter of short charging distance.  The largest was ten cm. Also as charging conditions, the devices ought to be placed in a very mounted position.
Rim said, “Our transmitter system is safe for humans and compatible with alternative electronic devices, we have solved  major problems with short charging distance and therefore the dependence on charging directions,”


Wireless power transfer is a technological breakthrough. It helps to reduce the cost of buying multiple cell phone charger. Is portable and affordable.
