In the Jingdong Apple store will have these two versions for us to choose, the main reason is that there is still a corresponding inventory of wireless charging box version in the Jingdong Apple store, which will naturally let us make a certain choice. It is important to know that no matter what version of the charging case we choose, the performance of the AirPods Pro is the same, and there is no major difference.
There is a packaging film. airpodspro2 generation is suitable for running playground, PRO2 middle bottom adopts two layers of LIGHTSTRIKEPRO foam layer material equipped with claw carbon fiber material ENERGYRODS, and carries out "weight reduction" operation on the structure. Earphone anti-counterfeiting labels and seals are anti-counterfeiting trademarks, which can be pasted, printed, and transferred to the top of the product or product packaging, or the subject matter appendages (such as commodity listings, business cards, and anti-counterfeiting cards).
Appearance check, function test. Appearance check, the real AirPodsPro2 looks exquisite, the details are perfect, and the counterfeit products existSome flaws. Functional testing. The real AirPodsPro2 has excellent noise reduction and environmental sound transmission functions, while the counterfeit products have poor sound quality and poor noise reduction effect.
Because your AirPods are not the new wireless charging box (the 1599 model), but the first generation box (plug-in charging) and your headphones are the second generation, so you see the model number on the box is A1XX, the phone is shown as A2XX, but the serial number is the same.
airpods2 Distinguish between true and false methods: regular AirPods2 The packaging is very precise, the plastic seal is very close to the packaging box, if there are bubbles and the like, this process is likely to be fake. There are labels on the outer packaging, the regular AirPods2 packaging labels are very neat, will not be casually crooked, fake in order to save time.
Hello! Jingdong's own products are relatively good specifications, wireless chargers do not affect the machineIt is big.
Connect the charging head to the charging base using a data cable, and then plug the charging head into the power supply. Place the charging base on the table, with the phone's screen facing up in the center of the charging base. After the phone is placed on the charging base for a few seconds, there is a "drip" sound, indicating the start of charging. Huawei mate40pro uses the standard 66W wired fast charge, which can be filled 76% in 30 minutes and fully filled in 49 minutes.
No. The principle of the wireless charger is a magnetic field generated by the current through the coil, and the coil close to the magnetic field will generate an induced current, so as to achieve itThe current is transmitted wirelessly. Wireless charging technology is a special way of power supply, it does not need the power line, rely on electromagnetic wave propagation, and then the electromagnetic wave energy into electricity, and finally achieve wireless charging.
Huawei 27W fast charger has no effect on Apple, if you use Huawei's fast charger to charge Apple's mobile phone, it may not be able to enter the fast charging mode, only the ordinary charging mode, the ordinary charging mode has no effect on Apple's mobile phone, but the charging time will be slower.
The charge efficiency is not high. The efficiency of charging decreases dramatically once the distance is even slightly greaterIt takes a lot of time and resources to complete the charging, so the use is not meaningful. Safety issues in the charging process. High-power wireless charging equipment will produce a large amount of electromagnetic radiation, which will cause certain adverse effects on health, but also have interference effects on aircraft and communications. The first practical aspect.
BEST BST-50000M Charging treasure BEST BST-50000M charging treasure is equipped with double USB output interface, built-in circuit chip to optimize discharge efficiency, intelligentIdentify charging equipment, and provide multiple security protection, including temperature protection, short circuit protection, reset protection and other 11 circuit protection.
Xiaomi mobile power: Xiaomi is known for its high cost performance, its mobile power uses high-quality batteries, and provides stable charging performance. Anker Power Bank: Anker's products are praised for their high quality and durability. Romas Power Bank: Romas power bank is known for its large capacity and high cost performance.
Qiku power Bank. Twenty thousand can choose Rome Shi charging treasure, twenty thousand is not bad, Jingdong self-owned 79 can buy, is not howWireless charging is unstable.
The reasons for this situation are as follows: First, the magnetic phone case will interfere with the wireless charging coil of the phone, affecting the charging effect. The wireless charging coil of the mobile phone needs to be accurately aligned with the coil of the charger to achieve charging, and the magnetic phone case will change the shape and weight of the mobile phone, making the wireless charging coil and the coil of the charger cannot be accurately aligned, resulting in poor charging effect.
It is estimated that the charger output power is insufficient and the automatic protection stops the output. Although the original charger of the mobile phone is 5V1A, the actual input can be more than 1A, and the 5V2A charger can be used. If the wireless charger output power is only 5W, it is not enough. Only the money spent on the wireless charger, and no input and output parameters, is not matched. The power of the Bluetooth headset is too small to explain the problem for comparison, but it can explain that the wireless charger is available.
