HandThe wattage of the machine charger also depends on the current. Because wattage is equal to current times voltage. If it is 2A specification, then the 5v charger wattage is 10w, 9v is 18w; If it is 5A specification, then the 5v charger wattage is 5w, and the 9v is 15w. The 5V and 9V marked on the mobile phone charger refer to two different voltage levels that can output 5V and 9V, and 2A refers to the maximum output current of 2A.
The fast charge power of the mobile phone charger can range from 20W to 120W. Among them, the charger from 20W to 30W belongs to the regular operation, and the charger from 40W to 65The charger of W belongs to fast charging, the charger from 65W to 100W belongs to ultra-fast charging, and the charger above 100W belongs to flash charging or second charging; For example, for a mobile phone with a battery capacity of 4000mAh, it is fast to charge using a charger with 65W or more power.
If the charging power of the charged device is higher than 66W, it is recommended to select 120W fast charge. If the charging power of the charged device is lower than 66W, 66W fast charge is recommended. 120W fast charge technology uses the Type-C interface, which can quickly charge the mobile phone in a short time, according to the actual measurement, so thatWith a 120W fast charge, the phone can be fully charged in 30 minutes. In addition, 120W fast charge also has intelligent recognition, automatic regulation of voltage and other characteristics, which can better protect the battery.
At present, the mobile phone that supports 120 watts fast charge on the market has been able to achieve very fast charging speed. For example, iQOO 7 supports 120W ultra-fast flash charge, which can be charged to 100% in 15 minutes. In the actual experience, the iQOO 7 from 1% to 100% takes only 14 minutes and 58 seconds. This charging speed has been able to meet the fast charging needs of most users.
The fastest fast charge Apple supports is 30W. However, it should be noted that the maximum charging power supported by the iPhone is 20W, so when using the 30W fast charging adapter to quickly charge the iPhone, it can only reach 20W charging speed. At the same time, according to the latest reports, the iPhone 14 Pro Max supports up to 27W peak power, while the iPhone 14 standard edition supports up to 25W fast charge.
Look at the phone model, try to choose 20 watts or 30 watts. Such as 14 Series: iPhone 1iPhone 14 Plus, iPhone 14 Pro These three phones charge up to about 26W, iPhone 14 Pro Max charging power up to about 29W.
iphone14 with 30w fast charge. If you use a 20W charging head to charge the iPhone14, the theoretical maximum full load is only 20W, which does not reach the peak charging power of the iPhone14. The actual data from the test media can only reach 1 using Apple's own 20W charger9W charging power. W.
It is possible to use a 65-watt charger to charge a 20-watt phone, but the power of the charger exceeds the maximum charging power of the phone, so the phone automatically limits the charging power, and the maximum charging power is still 20 watts. This means that charging with a 65-watt charger will not be faster, but the charger will work normally, so it can be said to be backward compatible.
iPhone13 series. These phones all support fast charging technology, which can fully charge the battery in a relatively short time. The 18W charger also works with some iPhone hand models, the iPhoneX, iPhone ExR, iPhone EXS series and iPhone11 series. These phones all support fast charging, which can be improved by using an 18W charger.
1, the fast charge power of the mobile phone charger can range from 20W to 120W. Among them, the charger from 20W to 30W belongs to the regular operation, the charger from 40W to 65W belongs to the fast charge, and the charger from 65W to 100W belongs to the ultra-fast charge and 100WThe above charger belongs to flash charge or second charge; For example, for a mobile phone with a battery capacity of 4000mAh, it is fast to charge using a charger with 65W or more power.
2, the average smart phone charger output power is 5 ~ 10W. The output voltage is 5V and the output current is 1 ~ 2A. The power of the phone charger is output voltage X output current, which can be seen on the adapter nameplate. The wattage of the mobile phone charger generally refers to the output part, the output wattage = output voltage x output current. The output is generally open from 5V, 800mA (0.8A) or 5V, 1AAt first, this is the standard USB0 voltage and current output.
3, there is no actual 240 watts of charging power on the market, but there are many mobile phones that support 120 watts of fast charging, such as iQOO Xiaomi 10 Supreme commemorative edition, Redmi K50 Pro, OPPO Find X3 Pro and so on. The current state of cell phone battery and charging technology has not been able to support such a high charging power of 240 watts.
4, watts. Mobile phone fast charging technology is developing rapidly, and the highest wired fast charging power can reach 240 watts. Now in the worldOnly one smartphone has 240 watts of fast charging, the Real Me Neo5. In addition, there are some mobile phones with higher charging power, such as ace2pro 150w fast charge, Red Devil 9SPRO 165w fast charge.
5, the charger output voltage multiplied by the output current, such as the ordinary mobile phone charger output is 5V-2A 5X2=10W, the charger will be marked but marked for the charger end of the maximum output value and not necessarily the phone charging power, the actual charging output will change due to the phone can withstand the power change. The actual charging power can be loweredUse the third-party APP 'AccuBattery' for testing.
6, the early mobile phone charging power is usually around 5W, such as the iPhone 5 and its previous version of the charger power is 5W (5V/1A). With the progress of technology, fast charging technology began to rise. For example, Apple's iPhone 8 and later versions support 18W fast charge (9V/2A), while some Android phones support higher fast charge power, such as 20W, 30W or even higher.
