Generally speaking, the input voltage of the charger for mobile phones and other devices is 5 volts. ... A charging head equipped with this input voltage is sufficient. However, not all batteries used in electrical appliances have a 5-volt input at the charging end, and there may be other input voltage indicators. Therefore, according to the technical parameters of the standard charger to choose the charger that matches it is the most correct choice.
has indicated that the input is 5V2A, that is, the 10W charging head input, the output is 5V1A, and the output is 5W. Charging is slow.
This depends on the maximumWireless charging power up. For example, Xiaomi's 20W wireless charge, the default distribution is 27W charging head. Of course, this is the best configuration, low play can not play wireless power, high waste. The charging head is higher than the wireless charging power, because the conversion process has energy loss.
Required, the fast charge head is divided into three models: standard 5v1A, fast 5v2A (30% speed increase), and flash 9v2A (50% speed increase). Wired charging and wireless charging use the same fast charging head.
Wireless charger does not have to use the original charging head, as long as the interface is consistent, the voltage is the same, and the current is the same>
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
Wireless charging means that by wireless meansElectronic devices provide electricity. Wireless charging is a modern technology that does not require a traditional physical cable connection to charge electronic devices. The basic principle is to use electromagnetic induction or radio waves to transmit energy. This technology uses a charging dock or charger to wirelessly sense the device to transfer power. There are many ways to implement the specific principles and technologies of wireless charging.
1, the mobile phone standard charger and data cable connected to the wireless charger, and then handThe machine is placed (vertical) or horizontally in the center of the wireless charger base, wireless charging can be achieved, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
2, open the phone, click to enter the phone Settings. On your phone's Settings page, tap the Battery and Performance TAB. In this page, click Battery in the right column to enter the battery page. Click to enable the wireless charging function. Click on the bottom corner to turn on the wireless charging function.
3, wireless charger use method: the mobile phone standard charger and data cable connected to the wireless charger, and then handThe machine is placed in the center of the wireless charger base, wireless charging can be realized, the indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick.
4, first of all, we need to confirm whether our millet 11 supports wireless charging function. You can view this information in your phone's Settings. Enter "Settings" - "Battery and Performance" - "Wireless charging", if the "wireless charging" option appears, it indicates that the device supports wireless charging. After confirming that the device supports wireless charging, we need to prepare a wireless charger that supports the Qi standard.
5,Turn on wireless reverse charging Settings: The phone enters the battery setting, turn on the wireless reverse charging switch. Tips: (1) Do not enable the wireless reverse charging function on the charged device. If the reverse charging function is enabled on two mobile phones at the same time, one mobile phone will randomly switch to the receiving end, which may cause abnormal charging. (2) After the wireless reverse charging function of the mobile phone is turned on, please do not place the mobile phone directly on the metal material.
6, at present, the most perfect wireless charging function of the two mobile phones, is Apple and Samsung, then let's introduce how to use these two phones for wireless charging. Handle-shaped appleIf the phone and the charging back clip are connected to each other, the interface is perfectly combined. The port connects directly to the phone, a process that does not use a charging cable. Then put the connected phone on the charging pad.
