However, even using the current EPP standard, it typically takes 2.5–5 hours to charge a typical smartphone, with a typical 10 Watt-hour battery, which would imply that if the charge rate was 10 Watts, it would take only one hour. Therefore 2.5 hours charge time means the average charging rate was only 10/2.5 = 4 watts.
The proliferation of portable wireless communication devices such as mobile phones, tablet, and laptop computers in recent decades is currently driving the development of mid-range wireless powering and charging technology to eliminate the need for these devices to be tethered to wall plugs during charging.

Li-Fi modules. Li-Fi is a derivative of optical wireless communications (OWC) technology, which uses light from light-emitting diodes (LEDs) as a medium to deliver network, mobile, high-speed communication in a similar manner to Wi-Fi. [4]
Base Stations typically have a flat surface – referred to as the Interface Surface – on top of which a user can place one or more Mobile Devices. There are two methods for aligning the transmitting coil (part of the Base Station) and receiving coil (part of the Mobile Device) in order for a power transfer to happen.
Wi-Charge was founded in 2012 by Victor Vaisleib, Ori Mor and Ortal Alpert. The company is developing a unique far-field wireless power technology based on infrared laser beams. In 2015, Wi-Charge demonstrated its first prototype capable of charging small electronic devices. [1]
Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.
The technology was also being used for the McLaren Speedtail Hyper-GT by 2020. [20] [34] In May 2020, China published their national standard for EV wireless charging which incorporated WiTricity's technology, [35] [36] and WiTricity played a key role in establishing SAE International's J2954 standard for wireless power transfer. [34] [37]
eCoupled is a proprietary near-field wireless energy transfer technology developed by Fulton Innovation, a division of Alticor. It provides wireless power transfer via inductive coupling between a primary transmission coil and a secondary receiving coil. A single primary coil can provide power to multiple secondary coils at the same time. [1]
