In the era of rapid development, are you still showing off the capacity of your portable power source with many features? Then you are already backward. Battery technology is still stuck in the bottleneck and does not break out. So, it is to make their own intelligent machine Sustainable power supply ，only Quick Charger technology ensure that portable power source is faster than others.

There are mainly two kinds of common charging technology in the market ,one is Qualcomm ，another one is MTK。Focuses is the key to introduce Qualcomm QC2.0 today.

First, Qualcomm is a professional cell phone chip company,QC2.0 is a specification for charging, which was manufactured by Qualcomm in 2014.There are two levels: level A (5V, 9V, 12V), level B (5V, 9V, 12V, 20V). The current most of us use A-level program, otherwise they only the use of Qualcomm Snapdragon 800 or more mobile phones or tablets ,and so that they will have QC 2.0 agreement.

Commonly 99% of mobile phones ’ voltage are 5V output, but the QC2.0 charger default 5V output. So all of the phones can be used QC2.0 charger, But it will not have the effect of quick charging. To achieve the effect of quick charging, Mobile phones, data lines and chargers have to reach the same agreement, Commonly known as: handshake agreement.
