1, when going out, you can charge your phone without plugging it in. Small size, easy to carry, can be carried with the sound. It can charge many electronic products in time, such as mobile phones, PDAs, digital cameras and so on. In a normal charging environment, the test results show that the mobile power supply is safer than the general charger. Mobile power is better thanThe general charger is safe and reliable, and it is necessary to buy a mobile power supply.
2, can increase the use of your equipment, so that you can enjoy more entertainment or office phone and other business. Generally, it can be used to prevent mobile phones or laptops from being unable to use when the power is insufficient. We must choose good quality when buying, poor quality is easy to burn and damage the phone. It can increase the time you spend using your device, allowing you to enjoy more entertainment or business such as office calls.
3, high-speed charging Second, the most commendable is its fast charging ability. Compared with other brandsHuawei mobile power supply uses a super large current output interface to provide 5V/9V/2A/5V/5A two rates of transmission, the fastest to achieve 40W power output, and even for high-power devices such as laptops, users can achieve fast charging experience, to solve the user's "urgent need for charging" problem.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radioWave transmission and other methods, wireless charging of mobile phones mostly use the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. As shown below.
Wireless charging source is installed inside a electromagnetic coil, after the power switch is turned on, the electromagnetic coil will convert the electric energy of the power supply battery into a large amount of magnetic energy, and then use a reverse coil (international standard brick QI coil) to receive this large amount of magnetic energy, and convert it into electrical energy through aMetal output heads are fed into our device reserve batteries. Wireless charging Because electromagnetic transmission only needs to be transmitted in space, no medium is required, so wireless charging can be carried out.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Electromagnetic induction, magnetic field resonance, electric field coupling wireless charging to charge the mobile phone principle. Most of the wireless charging on the market now uses electromagnetismvivo X21 does not support wireless charging. The vivo X21 is powered by the Qualcomm Snapdragon 660 AIE mobile platform and 6GB of RAM. vivo X21 adopts OLED shaped full screen on the front, 3D curved glass on the back, full screen with bangs, vivo calls it U-shaped groove, providing ice diamond black, aurora white, ruby red, charming night purple four colors.
Hello These two mobile phones do not support wireless charging function, so they can not directly wireless charging. If wireless charging is necessary, you can add a wireless charging deviceIt's okay. But the current wireless charging effect is not so good.
vivo X21 screen fingerprint version does not support wireless charging function, the model supports dual engine flash charging function, you can understand.
1, cellular mobile communication can provide wide coverage, high mobility and low and medium data transmission rate, it can use the characteristics of WIFI high-speed data transmission to make up for its own data transmission rate limited deficiency. And WIFI doesn't justUsing the perfect authentication and billing mechanism of the cellular mobile communication network, and combining the characteristics of the wide coverage of the cellular mobile communication network, the multi-access switching function can be implemented. Like Bluetooth, Wi-Fi wireless Fidelity is a short-range wireless technology used in offices and homes. The technology uses the band around 4GHz, which is currently an unlicensed wireless band. There are two standards currently available, namely IEEE8011a and IEEE8011b. This technology has its own advantagesTherefore, it is favored by manufacturers.
3, second, NDSL (Nintendo DS Lite) is an improved version of NDS, launched in 2006. On the basis of maintaining the core functions of NDS, NDSL makes the hardware lightweight and thin design, making the game console more portable and comfortable. In addition, NDSL has added some new features, such as built-in Wi-Fi support, making it easier for players to play online.
4, with their own computer to form a wired wireless hybrid network, the computer through the network cable in the form of wired Internet, NDSL, PSP, notebook and other Settings through a wireless connection to the Internet, convenient and convenient.
5, Nintendo DS (Nintendo DS, referred to as NDS), is a portable handheld game instrument developed by the Japanese Nintendo Company, DS is the abbreviation of Dual Screen (dual screen). Key features include a dual screen display, with the lower screen being a touch screen, equipped with a microphone (voice input device) and Wi-Fi wireless networking capabilities.
iPhone series: From the iPhone12 and later models, including the iPhone1iPhone12Mini, iPhone12Pro, iPhone12ProMax, and iPhone13 series, Such as iPhone1iPhone13Mini, iPhone13Pro, iPhone13ProMax. Samsung Galaxy Series: From the GalaxyS6 and later models, including the GalaxySGalaxy SGALaxySGalaxySGalaxySGalaxySGalaxyS21, etc. Almost all small electronic devices can be charged with a power bank, and the iPhone13promax is no exception.
Apple 13promax charging can not use 12000 mah charging bank. Charging treasure usually has a large capacity, common in 5000 to 10000mAh, some will be higher, such as Li Chong charging treasure has 12000mAh electricity. When the battery level is below 25%Even if the booster circuit is assisted, the charging efficiency will be reduced because the voltage of the lithium cell will drop more.
