Back in March, LG Innotek initially announced they were working on a 15W wireless charger. The company told us they would begin manufacturing these modules for smartphones and vehicle chargers sometime this year. It seems LG has been hard at work on this accessory as the company has just announced they will begin selling this product in North America, Europe, and Australia sometime this month.
At the time of its announcement earlier this year, we were told this wireless charger would support both WPC 15W and PMA 5W. However, the press release for the product now does not mention PMA support at all. Instead, it just mentions that it meets the standards laid out by the Wireless Power Consortium (which is the organization that brought us Qi wireless charging). So we should not expect the charger to work with PMA (Power Matters Alliance) devices at this time.
Typical wireless chargers use a 5W charging module, but this new Quick Wireless Charging Pad from LG will use a 15W module. The company says it will be able to charge a battery to 50% within 30 minutes. Oddly enough, LG doesn’t give us a battery capacity when talking about this statistic though. As a reference point, we’ve seen Samsung’s fast wireless charger completely fill the 3,000mAh capacity battery of the Galaxy S7 in about 2 hours.
LG Innotek says they’re focused on keeping heat generation down as well. They understand that heating the battery up too much can cause degradation of the battery as well as making the battery more susceptible to explosion. To combat this, the company says they’ve embedded a sensor into the Quick Wireless Charging Pad to monitor the temperature of the smartphone. If it reaches a certain limit, then it will stop charging the device for a few moments.
Once the device reaches the desired temperature again, the Quick Wireless Charging Pad from LG will go back to charging the battery.
