LG Innotek announced on Oct. 12 that it has succeeded in the commercialization of a 15 Watt wireless charging pad for the first time in the world. The product allows smartphone users to charge their devices as fast as when using a wired charging module.
The wireless charging pad supplies electric power to smartphone in a slim pad form. If users put a smartphone on the pad, the pad starts to charge the battery of their phone wirelessly.
The product will be sold in North America, Europe, and Australia in the middle of this month by the global smartphone accessory manufacturer.
The 15 W wireless charging pad’s charging speed is three times faster than the existing 5W wireless charging module. It can charge a completely depleted battery to the level of 50 percent within 30 minutes because it supplies smartphone battery with 15W power equal to wired quick charger.
Also, this product boasts high compatibility and can be used with most of the wireless charging smartphones currently available in the market. It meets the standards of the Wireless Power Consortium (WPC), an international standardization organization for wireless charging.
LG Innotek adopted a technology that prevents the pad from overheating while charging, which can even reduce the risk of battery explosions and the performance deterioration of the smartphone.
The embedded sensor measures the temperature of the point where the pad is connected to the smartphone and suspends the supply of the electric power when it reaches a certain level.
Techno Systems Research (TSR), a marketing research firm, reports that the sales of the wireless charging transmitter-receiver module reached US$553 million in 2015 and will increase to US$2.2 billion in 2019.
