Mobile phone chargers can be roughly divided into travel chargers, cradle chargers and maintenance chargers. Generally, users mainly contact the first two. And the most sold on the market is the travel charger. There are also various forms of travel chargers. The common ones are the cheap duck egg-shaped miniature travel charger, the ordinary desktop card board charger, and the high-end desktop charger with crystal display. Mobile phone charger, also known as: mobile phone adapter, is actually composed of a stable power supply (mainly regulated power supply, providing stable working voltage and sufficient current) plus necessary control circuits such as constant current, voltage limiting, and time limiting. The output parameters marked on the charger (referring to the line charger): such as output 5.0V/1A, output 5.0V/1500mA-11200... refers to the relevant parameters of the internal regulated power supply. Understand this truth, you will know that a (good quality) mobile phone charger is easy to change into a good quality regulated power supply. The chargers of lithium-ion (li-ion) batteries commonly used in mobile phones use a constant-current and voltage-limited charging system, and the charging current is generally around C2—that is, the charging rate is two hours. For example, a 500mAh battery is charged at 250mA in about two hours 4. Constant voltage charging after 2V. The lion battery is not suitable for the -DV/DT detection fast charging method used by the NIMH battery advanced fast charger, because the lion battery has a strict limit on the charging current. Lithium ion (Li+) is very active, and high current charging is prone to danger. The general user contacts are mainly the first two. The most popular travel chargers on the market are travel chargers. There are also various forms of travel chargers. The common ones include cheap duck-egg miniature travel chargers, ordinary desktop card board chargers, and high-end desktop chargers with LCD display. device. In view of the fact that most mobile phone users are non-professional users, the chargers basically have the function of full self-stop, and most of the travel chargers are fast chargers, and the charging time is about 1-3 hours. Many chargers on the market advertise that they are controlled by microcomputers, including some very cheap duck-egg-type miniature travel chargers. In fact, strictly analyzed from the charging circuit, only a small number of chargers can be truly controlled by microcomputers (MCU control). . Some manufacturers claim to be "microcomputer control" when they use integrated blocks on the charging circuit. In fact, many low-cost design integrated blocks are cheap op amp integrated blocks, while some dedicated charging control integrated blocks have higher unit prices. , generally used in relatively high-end or brand-name chargers. So we can't trust the so-called microcomputer control, especially the cheap products. Many products are similar in appearance but have very different internal circuits, and their performance is also very different.Original Samsung Wireless Charger Adapter qi Charge Pad For Galaxy S7 S6 EDGE S8 S9 S10 Plus Note 4 5 For Iphone 8 X XS XR mi 9original Samsung Wireless Charger Adapter qi Charge Pad For Galaxy S7 S6 EDGE S8 S9 S10 Plus Note 4 5 For Iphone 8 X XS XR mi 9 Features: 1-100% S6 Edition QI Wireless Charger Pad 2-5W Charging,Desktop Stand Charger Pad 3-OUTPUT:5V/2000MA 4-50CM Micro USB Data Cable 5.

Xiaomi Redmi 9A runs Android 10.0 and has a 5000 mAh Battery. The 5MP front camera is for taking wide-angle photos. A normal camera lens takes a 75° angle photo and the problem with that angle is that it's a small frame that is not good for group photos or scenic photos. To take wide-angle photos, you need a wide-angle camera. With a wide-angle camera, you get an angle that fits everything on the frame without you moving back to capture the whole scene.The camera is for taking close-ups of small objects. Trying to capture close-ups of small objects can be difficult using a normal camera lens. The more you move your smartphone towards the subject the more distorted the image becomes. With a macro camera, you can take clear, detailed images of up to 2.5cm of the subject without losing clarity.General FeaturesPlatform: Android 10, MIUI 12Processor: MediaTek Helio G25 (Octa-core 2.0 GHz Cortex-A53)GPU: PowerVR GE8320 (650 MHz)Memory: 2GB RAMSIM Type: Nano-SIMSIM Count: Dual-SIM DisplayDisplay: 6.53-inch, IPS LCD Display, 20:9 ratio,  720 x 1600 PixelsFoldable Display: No CameraRear Camera: 13MPRear Camera Features: LED flash, HDR, Panorama, 1080 @ 30fpsFront Camera: 5MP StorageBuilt-in Storage: 32GBMemory Card Support: Yes, microSDXC (dedicated slot) Network Support2G GSM: 850 / 900 / 1800 / 19002G CDMA 1X: 850 / 900 / 1700(AWS) / 1900 / 2100 –4G LTE: Yes5G: No Internet & ConnectivityGPRS: YesEDGE: Yes3G/WCDMA/HSPA: YesHSPA+: YesCDMA EVDO: Yes4G LTE: Yes5G: NoWLAN: Wi-Fi 802.11 b/g/n, HotspotWi-Fi Hotspot: YesBluetooth: Yes, Bluetooth 5.0, A2DP, LENFC: NoInfrared Blaster: YesUSB Port: Yes, USB Type-C (2.0), Reversible Connector Other FeaturesVideo Streaming: YesActive Noise Cancellation: –Wireless Charging: NoBuilt-in Mobile Payment: –Water Resistant: NoDust Resistant: No BatteryBattery: 5000mAh Non-Removable Li-Po Battery ConnectivityThe Xiaomi Redmi 9A features a 3.5mm headphone jack, a USB Type-C port, Wifi, and Bluetooth 5.0 connectivity.
