The power of the power bank is usually expressed in watts (W), representing the amount of power it can provide.The power directly affects the charging speed of the power bank.
The power of 20W and 66W power packs is significantly different.In general, a 20W power bank is suitable for charging small devices such as smart watches, Bluetooth headsets, etc., but it may be slower for high-power devices such as laptops or large screen mobile phones.In contrast, the 66W power bank has higher power and good adaptability when charging various devices, including laptops and large screen mobile phones, and its charging speed is relatively fast.
It should be noted that although the 66W power bank has a faster charging speed, it also needs larger capacity and higher cost.Therefore, in physics, it may also cause inconvenience of large volume and high price.In addition, the use of high power for rapid impact may also generate more heat, which should be carefully considered during use.
In conclusion, please carefully weigh the power options provided by different products according to your personal circumstances when selecting the use scenarios and needs that are suitable for you.
The difference between the two power packs is their capacity. The letter w here represents the storage capacity watt hour (wh).For example, if a 10 watt incandescent bulb is lit with a power pack, a 20w power pack can drive the bulb to illuminate for two hours continuously, and a 66w power pack can drive the bulb to illuminate for six and six hours continuously.
It is OK to use a 66w charger to charge a 40w fast charging mobile phone, but the following two conditions need to be met: 1.66w charger has a mode of 40w power; 2. Whether the mobile phone is of the same brand and supports fast charging; Condition 1: Whether the 66w charger has a mode of 40w power; not all 66w chargers can charge a 40w fast charging mobile phone,Because different chargers may have different output voltage and current combinations.If the 66w charger does not have the mode of 40w power, it may not be able to communicate and negotiate with the mobile phone normally, which may lead to failure to start fast charging or overvoltage and overcurrent problems.Therefore, before using the 66w charger to charge the 40w fast charging mobile phone, you need to check whether the 66w charger supports the 11V6A, 10V4A, 9V4.5A and other 40w power modes.If it is supported, it can continue to be used;If not, it is recommended to replace the charger with another one that meets the requirements.Condition 2: Whether the mobile phones are of the same brand and support fast charging. Since all major mobile phone manufacturers in the market have their own unique fast charging protocols and technologies, not all mobile phones can use any brand and model of fast charger for fast charging.Different brands have different designs and optimizations in output voltage, current, frequency, coding, etc.These designs and optimizations aim to improve charging efficiency, security and stability, but also lead to incompatibility between fast charging protocols of different brands.For example, Huawei's super fast charging can only be used on Huawei's mobile phones that support this technology.
The power bank 66W refers to the charging power that is exactly 66W by multiplying the voltage by the current.Its unit is Watt, referred to as "Watt", and its symbol is W. As a physical quantity representing the speed of work done by the current, the power of an electrical appliance is numerically equal to the electric energy it consumes in one second.If the electric energy "W" (SI unit is J) is consumed in such a long time as "t" (SI unit is s), then the electric power of this consumer is P ＝ W ／ t (definition formula). The electric power is equal to the product of the voltage at both ends of the conductor and the current passing through the conductor.
Mobile power supply and mobile charger (mobile power, mobile charge, power bank, urine bag, wet nurse; English: Power bank) are portable and can store electric energy. A portable charger mainly used to charge consumer electronic products such as handheld mobile devices (such as wireless phones and laptops), especially when there is no external power supply.Its main components include: batteries for electric energy storage, circuits for stabilizing output voltage (DC DC converters), and most mobile power supplies are equipped with chargers for charging as built-in batteries.
Can the Matebook13s be charged with Huawei's own 66W charging bank?It can be charged, but the actual charging speed is not as fast as the original 65W on the laptop.Generally speaking, the mobile phone will charge the computer and play the lol, and the power is getting smaller and smaller.However, the computer charger used to charge mobile phones is similar to the original mobile phone charger, which will not have much impact.
100W is better. The power of the power bank represents the maximum output power. If it supports 100W mobile phone charging, it will be charged at the speed of 100W. If it supports 20W mobile phone charging, the 100W power bank will also be charged at the speed of 20W, while 66W charging can charge 100W devices, but the charging speed will be reduced,For example, when charging a 66W power bank 96W laptop, the charging speed may not keep up with the power consumption speed, and the charging will become less and less.
1. In terms of parameters, the maximum current of the 66W super fast charge is only 4A, while the maximum current of the 22.5W super fast charge is 5A. It seems that the damage of the 66W super fast charge to the mobile phone is very small.
2. There is no doubt that the charging speed of the 66W super fast charge is much faster than that of the 22.5W super fast charge, which is the most inaccessible for us who often use mobile phones!
3. If the mobile phone supports 66W fast charging, and if the 22.5W power is not enough to charge the mobile phone, it is also bad for the charging quality of the mobile phone battery. In a word, it is better to choose the original charging of the mobile phone.
