Capacity selection When choosing a mobile power supply, capacity is a very important parameter. Based on daily needs, yesDetermine the required capacity size. If you often need to go out for a long time, or need to charge electronic devices such as mobile phones, tablets, etc., it is recommended to choose a mobile power supply with a large capacity. Output and input parameters The output parameters of a mobile power supply determine the charging speed and power it can provide to the device.
When selecting a mobile power supply, the main consideration is its capacity, output power, charging speed, number and type of ports, size and weight, and safety features. Capacity: The capacity of a mobile power supply is usually expressed in milliampere-hours (mAh), which determines how much power it can provide to the device. When selecting, make sure that the capacity of the mobile power supply is toLess than the phone's battery capacity, to ensure that the phone can be fully charged.
The selection of mobile power depends on the capacity, look at the cell, look at the agreement, look at the brand, look at the appearance, look at the channel and so on. Look at the capacity of the charging treasure nameplate are marked with battery capacity, rated capacity 2 data, battery capacity data is greater than the rated capacity, battery energy is generally 53 to 67 times the rated capacity. The battery capacity determines how much power the charging bank can store, and the larger the battery capacity, the more power the charging bank can store.
When choosing a mobile power supply, it is best to choose a smart power supply, which can be smart for mobile phones and so onp> Slightly slower charging speed: compared with wired charging banks, even with fast charging, the charging speed of wireless charging banks will be slightly slower, especially for devices with large-capacity batteries, and the charging time is longer. Compatibility limitations: Wireless charging bank requires devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
Each has its own advantages: wireless charging is convenient, no need to connect the phone to the charger, put it on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
The second kind of wireless charging, its workFor the principle of the use of the most is electromagnetic induction, wireless charging less line bondage, each charge with the release, compared with wired charging, it does not plug and unplug the data cable cumbersome, so charging is more safe, more fast, its disadvantage is that the charge is relatively slow.
What is the difference between wireless charging and wired charging bank? Although both are used to charge devices such as smartphones, there are some differences. Simply put, wireless charging is more convenient, does not require wire entanglement, can remove the trouble of wire; The wired charging treasure is faster in charging speed, such as the Secretary-General is a wired charging treasure, which supports PDTwo-way fast charge, charging speed is faster than the general product.
1, it is recommended that you use the standard charger to charge Using its wireless charging double coil can not add ntc His wireless charging double coil can not add ntc third-party charger Although it can also charge the mobile phone Wireless charging double coil can not add ntc, but due to charging specifications or chargingElectrical protocol and other differences Wireless charging double coil can not add ntc, may bring heat and other problems to the mobile phone.
2, generally the use of metal heat dissipation can reduce the heat transfer to the mobile phone wireless charging coil can not add ntc, thus affecting the mobile phone charging power, will inevitably increase the metal block on the circuit board or coil, a little similar to the notebook CPU plus copper tube heat dissipation. Or increase the active fan heat dissipation, and use the fan to cool the motherboard and coil, which can achieve the delay power reduction time.
3, it may be because the mobile phone opens high-power applications when wireless charging, such as: King of Glory, Tencent video and so on. When the app is opened, the CPU efficiency of the phone increases, increasing the power consumption, which causes the phone to heat up. The solution at this time is: turn off similar applications when wireless charging.
4, x is Apple X, the reason for x wireless charging heat is the wrong charging posture, the solution: use the correct charging posture to charge. The iPhoneX (pronounced "iPhoneten" in English) is in the early morning of September 13, 2017 Beijing timeA special edition of Apple's 10th anniversary released at 1:00 during Apple's 2017 Fall Product Launch event at the Steve Jobs Theater at ApplePark's new headquarters.
5, the phone is not used when charging the original charger. Charge your phone with a case. Solution: Do not use the phone when charging, if possible, it is best to shut down and charge. To charge the mobile phone, be sure to use the original charger, in the case of damage to the original charger, check the voltage and current displayed on the mobile phone box or mobile phone battery, find the suitable charging head, and then charge the mobile phone.
6,To avoid severe heating of the mobile phone, you can perform the following operations: It is recommended that you use the standard charger to charge the mobile phone. Although you can charge the mobile phone using other third-party chargers, due to differences in charging specifications or charging protocols, the mobile phone may heat up.
The root cause of the heat dissipation problem of high-power wireless charging is that the high-power wireless charging on the market now relies on high current to charge, but this situation is tantamount to increasing the resistance, thereby increasing its temperatureTherefore, it is necessary to use high heat absorption and high heat dissipation materials as the outer packaging, in addition, the corresponding resistance should be reduced, so as to fundamentally reduce the heat.
In addition, the heat dissipation design of the phone will also affect its temperature during wireless charging. If the heat dissipation system of the phone is not efficient enough, or the heat dissipation port is blocked, then the phone is more likely to get hot during the charging process. At the same time, the use of wireless charging for a long time or charging at high power will also exacerbate the heat of the phone. Finally, the use environment is also a factor that cannot be ignored.
It is recommended that you use the standard charger to charge using other controlsAlthough the three-way charger can also charge the mobile phone, it may cause problems such as heating due to differences in charging specifications or charging protocols.
Generally, the use of metal heat dissipation can reduce the heat transmission to the mobile phone, thus affecting the charging power of the mobile phone, which is bound to increase the metal block on the circuit board or coil, which is similar to the notebook CPU plus copper tube heat dissipation. Or increase the active fan heat dissipation, and use the fan to cool the motherboard and coil, which can achieve the delay power reduction time.
Compared to the old 10000mAh charging bank, although the new and old models in the appearance and interfaceThe color is changed from black to white, and the model WPB15ZM does not continue the old PLM11ZM, suggesting that there may be a technical upgrade. However, the rumors about the 20W wireless flash charge may be speculated to be untrue. The power limit of the wireless charging bank is the heat dissipation problem, high power may lead to overheating, posing a threat to the safety of the battery cell.
And the temperature is too high will lead to reduced battery life, charging temperature is too high, will lead to an irreversible decline in battery capacity. And a healthy way to charge is to avoid heat. Will Apple optimize this function by upgrading the firmware of the wireless charging pad through the phone?
