How many do you know about fast charge technology?

I will show you two formulas here first:

W= P (Power)* T (Time), P =U (voltage)*I (Current). We can regard W as the battery capacity.

The principle of fast-charge charger is that increasing the charging power P to shorten the time required for charging.

 

There are three ways to increase power, namely increasing the voltage U, current I, increasing the U and I simultaneously. In the guidance of these three ideas, there are three representative fast charge technologies:

1. High-pressure fast charge: Qualcomm Quick Charge 3.0/2.0 and MediaTek Pump Express Plus as representatives

2. Flash charging: OPPO VOOC

3. Low-pressure fast charge: USB 3.1 PD

 

The compatibility of fast charge:

1. The mobile phones that adopts Qualcomm Quick Charge technology: Samsung, Xiaomi, Sony, Asus, LG, Letv, ZTE, HTC and other brands of high-end flagship

2. The mobile phones that adopts MediaTek PEP technology: Meizu MX5, PRO 5, PRO 6, MX6 and so on

3. VOOC flash charge is OPPO’s independent research and development technology, only for OPPO phones. Special attention, the fast charge function of VOOC fast charge charger will not work on other phones.

 

Appacs is a mobile phone accessories exporter in China. We offer Quick Charge 2.0 usb wall charger and usb car charger.
