What is Adaptive Fast Charging for Technology?

"This technology allows the smartphone to use a higher charge capacity, because of this the devices can charge up to 50% faster."

Should I worry that the charger gets hot while charging?

"The purpose of this AFC technology is to get the phone charged faster to a percentage of 50 to 60 percent. During charging, the phone may become very hot. It will cool down after 60% of batteryi. Therefore, AFC is actually not used to fully charge a device."

Is AFC Technology compatible with all devices?

"AFC only works with devices that support this technology. This also applies to USB chargers and cables, which should also support AFC. Most models like the Samsung Galaxy Note 7 and the LG G Flex 2 support this technology because they use Qualcomm Quick Charge, the most common AFC producer."
