Meizu at Mobile World Congress event in Barcelona launched something really innovative and challenging for other companies who’re working or have worked in the same area. A few days before the beginning of the event, Meizu teased that it will bring something “faster than ever.” It was believed that the company would unveil a new smartphone with a faster processor. But, rather the company brought a new fast charging technology, named as mCharge that according to company claims can charge the smartphone 0 to 100% in just 20 minutes.
Meizu’s mCharge relies on 11V/5A charger to deliver 55W. This charge is delivered via an “upgraded data cable” that can support up to 160W. Meizu highlights its fast charging technology by comparing it with the Oppo’s Super VOOC fast charge tech that was introduced at MWC last year. Also, Meizu compares their latest tech with Qualcomm's Quick Charge 3.0 as well. Where VOOC support up to 20W and QC 3.00 to 18W, the new mCharge support it to astounding 55W.
According to Meizu, compared to these techs, mCharge doesn’t get heated up. According to Meizu’s notes, the SuperCharge get heated up to 38-degrees if the room temperature is 22-degrees. On the contrary, Quick Charge 3.0 attains as high temperature as 44-degrees.
Meizu says that Super mCharge uses Charge Pumps, thus utilizing the "two groups of conversion circuits to directly output half of the voltage." This leads to increase of the charging efficiency bringing it up from 9% to 98%.
Oppo’s Super VOOC Charge also claims to charge the phone to 100% in just 15 minutes, however, we are yet to see it getting implemented in the real case.
