The fast charge between vivo and iqoo can be universal, because iqoo is a subsidiary of vivo, and their charging protocols are the same. iQOO is a new sub-brand incubated by vivo and will operate independently from vivo to create a new flagship series. iQOO has four series of iQOO flagship, iQOO Neo, iQOO Z and iQOO U. iQOO operates independently from vivo to create a new flagship series.
Fast charging of mobile phones is mainly to shorten the time required for charging by increasing the charging power, and there are three means to achieve it: increasing the voltage, increasing the current, and increasing the voltage and current at the same time. These three paths are representative technologies, high voltage fast Charge Qualcomm Quick Charge 3.0\/2.0, Mediatek Pump Express Plus; Low voltage fast charge OPPO VOOC flash charge, USB 3.1PD.

Due to the differences in fast charge schemes of different mobile phone manufacturers, different brands of mobile phone chargers do not have the effect of fast charge when mixed, and may reduce battery life.

In addition, there are a variety of mobile phone fast charge agreements on the market. At present, there are several mainstream mobile phone fast charge protocols on the market

Apple's lighting and type-C use the USB-PD protocol, which is a fast charging protocol proposed by the USB-IF organization and can theoretically reach 100W. In addition to mobile phones, many devices such as laptops also use this protocol. Meizu uses the PE protocol introduced by Mediatek, which features a charger that allows it to determine the initial voltage required for charging based on current. Qualcomm QC fast charge protocol is a fast charge technology developed by Qualcomm for mobile phones equipped with Snapdragon processor, and PD fast charge protocol is compatible with QC protocol, so some non-Qualcomm processor mobile phones can also support QC fast charge protocol.

VOOC flash charge is OPPO's independently developed fast charging technology, and it is also the world's first mass-produced commercial fast charge solution, which requires a customized adapter and battery to be used together. It adopts a low voltage and high current scheme, and the electricity conversion rate reaches 95%. The VOOC flash charge was first used on the OPPO Find 7, which uses a 3,000mah battery to charge the phone to 75% in 30 minutes. OPPO's VOOC flash charge is compatible with OnePlus's WARP flash charge, which is realme's DART flash charge, so chargers can be universal between them.
Can not be universal, because the charging line to withstand the power is different, iQOO mobile phone and vivo mobile phone fast charging power is 40 watts and 60 watts, so the charging line in the process of use will be burned off
