is a technology that can quickly charge and discharge, which can greatly shorten the charging time and discharge time of the battery, and improve the efficiency and convenience of the battery. The implementation of
depends on the characteristics of the battery itself and the design of the charger. At present, there are mainly the following kinds of
on the market:
High voltage fast charge technology: This technology improves the charging speed by increasing the output voltage of the charger. However, this technology requires the battery itself to support high voltage charging, otherwise it will have an impact on battery life.
High current fast charge technology: This technology increases the charging speed by increasing the output current of the charger. However, this technology requires the battery itself to support high current charging, otherwise it will affect the battery life.
Wireless fast charge technology: This technology realizes wireless charging through the principle of electromagnetic induction. However, the charging speed of this technology is relatively slow, and the distance between the charger and the battery is relatively close. In general,
can greatly improve the efficiency and convenience of the battery, but it should be noted that different
has a certain impact on the life and safety of the battery, so it is necessary to choose
according to their own needs and the characteristics of the battery.

There are two general directions to improve the charging speed, one is to increase the voltage and the other is to increase the current. Increasing the voltage will increase the heat generated during charging, accelerate battery aging and may bring safety risks, so the actual effect is not good. Raising the current, by contrast, is much more realistic. VOOC technology uses a low voltage and high current mode to ensure the safety of the charging process. VOOC fast charging results are excellent. Thirty minutes can charge a 3000mAh battery by 75%, and 10 minutes is enough to charge a two-hour conversation.
The first generation of VOOC chargers was bulky and had a risk of breakage at the charging cable connector. Fortunately, with the advancement of technology, the second generation of VOOC mini chargers has come out. Its size is already equivalent to the standard USB charger, portability is extremely high, and security is also perfectly guaranteed. OPPO also launched VOOC fast charge mobile power supply, vehicle power supply, etc., to provide fast charging services anytime and anywhere. For now. The biggest drawback of VOOC technology is that it is only applicable to OPPO's products, and the compatibility is poor.
