1. The important parameters of the W9300 wireless charger are as follows: Voltage input: 12V voltage output: 5V, output current is 500mA, providing stable electricityForce transmission. Features: With LED indicator light, when charging, the indicator light will clearly display the charging status, convenient for users to know at any time. Scope of application: The charger is compatible with a variety of devices, such as the Samsung GALAXY SIII and GALAXY NOTE series, to meet a wide range of device charging needs.
2, in terms of compatibility, the second W9300 wireless charger performance is excellent. It works perfectly with Samsung's GALAXY SIII and GALAXY NOTE II, two popular smartphones that seamlessly charge wirelessly. At the same time, it alsoNokia's Lumia920 and Lumia820 are supported, which means that both Samsung and Nokia users can enjoy the convenience of wireless charging.
3, the traditional separation is MCU, charge management, DC-DC separation, 1A efficiency 88%, the advantage is that it has been widely accepted by the market. The most serious problem is that in the case of 2A output, the efficiency is low (about 83%), and the PCB heating is very serious. The software three-in-one is MCU plus external MOS, synchronous rectification, 1A efficiency of about 91%. The three-in-one hardware is implemented by hardware, and the software cannot be modified. 1A Efficiency 86About %.
4, Nank South Carolina wireless charging bank has a large capacity of 10,000 MA, support 18w strong output, in addition, Nank South Carolina wireless charging bank also supports 10W wireless fast charge, but also compatible with 5W/5W output, with iPhone 11 as a test object, the use of wireless charging for an hour can be charged half, The cost performance is absolutely nothing to say, and the configuration exceeds most brands of charging treasure on the market.
5, through the mobile power charging port, the maximum support 2A current input, full 10000mAh power time is about 6 hours. Mobile electricity>Line charging solution, MagSafe magnetic wireless charging, up to 15W wireless fast charging. It also supports Qi wireless charging scheme, which only supports 5W wireless charging power. Fast charging via USB connection to a computer or power adapter, up to 50% charge in 30 minutes, using a power adapter of 20 watts or more.
2, Apple 13 wireless charging power is 15W. Apple 13 wireless charging uses MagSafe magnetic charging technology, and is compatible with existing devices that support the Qi standard, and the maximum power of the Qi charger is 5W, compared with the pastThe iPhone offers the same specifications.
3, the iphone13 wireless charger is 15W. The iPhone13 supports up to 20W cable charging, MagSafe wireless charging (up to 15 watts), and Qi wireless charging (up to 5 watts).
This also depends on the size of its current, the general Android current is 2a (that is, increase the voltage and maintain the maximum current 2A), in this case 5-9 v power is 10 to 18 w. I wish you a happy, happy day code word is not easy, hope to adopt, thank you. < / p > < p > using the USB - C input interface, power 5 v0a / 9 v67a. AFC, QC, USB PD input of support.
15 watts with wireless charger. Samsung has the highest integrated mobile phone support 15 watts of quick charge, it can use two charging specifications, one is 5 v / 2 a, but only 10 watts. Another is 9 v / 67 a is 15 watts, using the latter is quick charge. The integrated use of QC0Fast charge agreement, belongs to the older one, and the current Samsung's new mobile phone S20 supports QC0 up to 25 watts of fast charge power.
The Vivos6 is equipped with a charger that supports up to 9V/2A fast charging and is compatible with 5V/2A wireless charging, but the maximum charging power of the data cable is only 8W. Although not the fastest, but can meet the needs of daily use.
If the charge does not start after 5 seconds, the position can be adjusted; Take away Settings that need to be charged for more than 2 minutes and the wireless reverse charge switch will automatically turn off. Tip: Don't use electricityThe amount is less than 20% to reverse charge the other Settings. Huawei Wireless charging principle Wireless charging technology uses two physical phenomena: current magnetic effect and electromagnetic induction.
2, wireless charging principle: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
3, if according to the charging efficiency is relatively normal, harmless to the human body in terms of standards, now can do the farthest distance should be 5-10cm, domestic microGoose Technology, Qualcomm should be able to do it. And this is not the public familiar with Qi wireless charging, is magnetic resonance wireless charging, based on the principle of magnetic resonance. Although there are also 1 meter or even farther wireless charging technology, but the current charging power of these are too small, charging speed is too slow, difficult to put into daily use.
A power of 10 watts, that is, 5v1a, can be charged to 1500 mah in an hour.
W Wireless charger, etcHow many amps is the output? The nominal power of the wireless charger is 10W, which refers to its maximum output power. At the standard voltage of 5V, the maximum current that a 10W wireless charger can provide is 2A. For mobile power supply, its parameters include input current, output current and capacity. If the input current of the wireless charger does not exceed 2A, any mobile power supply can be compatible with it.
w Charging is slow. 10W charging refers to the charger output power of 10W, that is, 5V2A voltage and current output. 10 watts of wireless charging is still relatively slow, an hour is estimated to charge 60About % of the electricity, basically in about an hour and a half can be full of mobile phone batteries. In the case of the iPhone, the official charging time is five hours on a full charge. If you use a 10W charger, the full charge time will be slightly shortened.
The current mainstream wireless charging power standard is 10W, which corresponds to the 5V2A charging specification. The wireless charging power supported by Apple phones is also generally in line with this standard. Some devices may support lower power, such as 5V5A, corresponding to a 5W charge rate. In contrast, wired charging is typically around 18W,Wireless charging is indeed slower.
Output: 1A or 2A This refers to the maximum output current capacity that can be provided to electrical equipment when the mobile power supply is discharged: 10400 mAh This refers to the capacity of the mobile power supply so 10W charger, as long as the mobile power input current is below 2A, all can be used! Expansion: W is a unit of power, indicating the amount of electricity consumed per unit of time.
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.
