The so-called "reverse charging" is the process of switching to the mobile power supply to discharge when the mobile phone is connected to other devices and charging other electronic devices, and the mobile phone is also the incarnation of the charging treasure. When the mobile phone with reverse charging function detects that the OTG device supporting data exchange between devices is inserted, the mobile phone outputs voltage to the VBUS on the USB data cable and prompts for reverse charging.
The following uses Huawei P40 Pro as an example: Enable wireless reverse chargingSetting: Enter the phone to set the battery and turn on the wireless reverse charging switch. Warm reminder: Do not enable the wireless reverse charging function of the charged device. If the reverse charging function is enabled for two mobile phones at the same time, one mobile phone will randomly switch to the receiving end, which may cause abnormal charging. After the wireless reverse charging function of the mobile phone is enabled, do not place the mobile phone directly on the metal material.
Reverse charging refers to the function of using the mobile phone as a mobile power source to charge other devices. First connect the two mobile phones with the OTG cable and the mobile phone data cable, and then change the USB connection mode in the notification bar toReverse charging. There is a premise here that the power supply phone supports OTG, if the other phone does not support reverse charging, the support end will automatically power.
The Huawei mate20pro is used as an example. The method of reverse charging is as follows: Choose Settings > Connect Device, and find the USB option on the page. The USB option is gray. So, first use a reverse charging cable to connect the phone to the device being charged. At this time, you will find that the USB option in "Settings" -- "Connect device" has become configurable, click to enter.
Wired reverseCharging Through the data cable (TYPE-C to TYPE-C cable) or OTG cable (OTG conversion cable needs to be purchased separately) can be charged for other mobile phones, bracelets and other digital devices. Connect one end of the OTG cable to the USB port of the mobile phone, and connect the other end to the USB data cable. Connect another mobile phone through the USB data cable to charge the mobile phone.
Wireless reverse charging refers to: the mobile phone as a wireless charging base, to support wireless charging devices (such as: watches, wristbands, mobile phones, etc.) to charge. Wireless reverse charging technology, derived from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
Wireless reverse charging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, and now can emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. However, its charging power is small and can only be used as an emergency.
NoneLine reverse charging is a charging technology that allows devices to charge other devices via wireless charging. Wireless reverse charging is based on wireless charging technology, but unlike traditional wireless charging, it is not just about charging a single device. In this technology, a device (often referred to as a "charging host") with wireless charging capabilities can also charge other devices that support wireless charging through its back or side.
Wireless reverse charging allows devices to charge each other without the use of wires or other connections. This technology was first introduced by Apple, and it allows Apple to set upFor example, the iPhone, AirPods, and Apple Watch charge each other. The principle of wireless reverse charging is to use the power of the device itself to charge other devices. Some smartphones and other devices have reverse charging, which allows them to use their own electrical energy to charge other devices.
Wireless reverse charging is to charge other devices that have no power by sending electromagnetic waves through the wireless coil; Both devices should support wireless charging, and can be charged without a data cable; Normal emergency use can, charging power is relatively small. At this stage, the market of mobile phones are basically supportedWith OTG function, but some low-end machines and individual mobile phones will not support due to cost constraints.
Wireless reverse charging function description: After turning on the wireless reverse charging switch, put the supported device (if it has a protective case, please remove it) on the back of the phone, you can start charging. Setting path: Set wireless Battery reverse charging. Tips: ① Need to be charged device support wireless charging function. In 2 minutesThis feature will be turned off if the device is not being charged.
Wireless reverse charging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, and now can emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. Wireless reverse charging is to charge other devices that have no power by sending electromagnetic waves through the wireless coil, and the two devices must support wireless charging, and they can be charged without a data cable.
