The key features of this charger are 'share and charge', fast charging and universal compatibility. Multiple ports and support for Android as well as iOS devices take care of the first two features. Now for the fast charging aspect, current input and output of DC 12-24V and 3.4A respectively, ensures a quick charge unlike conventional USB chargers providing 1.0A. Furthermore, Qualcomm Quick Charge are leaders in fast charging technology where Qualcomm 3.0 reduces charging times by up to half when compared to a standard 1A charger. Then, with the support of a type C port, this charger provides power to devices with those type C charging pins as well.
It should be noted that fast charging is only possible if your device supports it in the first place. However, even if it doesn't, there is no need to worry as a hand-shake mechanism ensures that your phone will draw only the amount of current it requires. So, it is still safe to use this charger to charge your smart phone, which obviously will not get a quick charge but still charge safely. In addition, an over-power protection fuse protects the charger from any power spikes, over-currents, harmful short circuits or overheating.
