From the era of smart phones, the size of mobile phone screens is getting bigger and bigger. In the past two years, under the rise of the full-screen trend, the size of the new machines has come to 6 inches. Although each generation of processors is doing its work. In terms of consumption, I have tried my best, but in the face of increasing performance and increasing screen size, the problem of battery life is getting more and more serious. Even for heavy users, one day has become a day. An extravagant hope, most users will pick up a mobile power backup when they go out.
In order to solve the problem of battery life, manufacturers are naturally exhausted. Before the battery technology has not achieved the large-scale commercial nature of the advancement, in fact, there are not many ideas left for them. The first is to increase the battery capacity. The battery is fundamental, and the battery with the larger configuration is of course more secure. However, in addition to the safety hazard, the large battery is usually accompanied by a volume limitation, in order to leave a structure for the large-capacity battery. Space, the mobile phone will inevitably become thicker and thicker, which is why the flagship mobile phone battery usually does not exceed 4000mAh.
On the other hand, since the mobile phone battery can't be made bigger, the charging efficiency becomes another option. 'Charging for 5 minutes, talking for 2 hours', this is definitely a slogan that everyone is familiar with, whether it is charging The outstanding performance of efficiency, or the attraction to users, can prove that users value the fast charge function. Although many manufacturers have their own fast charge technology such as VOOC flash charge, DASH flash charge, but to apply The widest, must be Qualcomm's QuickCharge.
Qualcomm's QC fast charge has now been developed to the fourth generation, here we can briefly understand. Initially with the emergence of large-screen smart phones, the original 5V/1A charging speed has been completely unable to meet the requirements, in a pile Among the standards, the 5V/2A generation fast charging standard has gradually been accepted by various families. However, as the entertainment function of the smart phone is further strengthened, the charging efficiency of 10W can not satisfy everyone, so the QC 2.0 standard comes along. Among them, the 5V charging voltage that has not changed for many years is finally no longer the only choice. In the case of equipment support, the high-voltage fast charging option of 9V/12V/20V is added, but the 20V file is actually due to heat and efficiency. Very few manufacturers choose, usually 5V/9V/12V third gear.
In the QC 3.0 stage, Qualcomm found that the problem is not limited to charging efficiency. The rude large-span boosting method makes fast charging become synonymous with high heat, so it adds INOV (Voltage Intelligent Negotiation Algorithm) in multiple files. When the voltage is adjusted, the voltage can be fine-tuned in units of 0.2V. At the same time, thanks to the Type-C interface, the current limit is relaxed a lot, not only the voltage regulation range is extended to 3.6-20V, but also the maximum current. Upgraded to 3A, the charging efficiency and heat performance have improved a lot.
As for the current QC 4+, in addition to further refining the voltage adjustment, it can be adjusted in units of 20mV. More importantly, with the further popularization of the Type-C interface, the industry is dominated by Apple, Google, Samsung, Qualcomm, etc. The USB-PD charging standard that we jointly launched is also supported, which means that we finally saw the dawn of the era of fast-charge standard.
The hammer technology QuickCharge 4+ charging kit (charge head + CC charging cable) that we have experienced this time supports QC 4+ and USB-PD fast charging, and can support 5V/3A, 9V/2A, 12V/1.5A, 3.3-. 5.9V/3A, 3.3-11V/2A, the maximum output power is 18W. Although it does not reach the highest 18W of QC 4+, the specific performance is also very expected.
The design of the charging head is relatively simple, the whole body is white, and the volume is basically the same as the fast filling head that comes with the previous nut mobile phone. It is relatively portable in the PD fast charging head. Type-C To Type-C data The quality of the line is also quite good, especially the user-friendly low-light light of the hammer at the interface end, which is indeed worthy of praise in terms of value and practicality.
Our experience is mainly divided into charging speed and temperature. As for the equipment used, it is naturally the hammer flag R1 of the hammer technology. Its own mobile phone is equipped with its own charging kit to ensure that there is no compatibility problem.
When the mobile phone is just plugged in, there will be a fast charge detection process. After a short-term protocol test, the charge can be turned on in the fast charge mode. Although the measured charge is adjusted all the way, the fluctuation is relatively stable. Stable around 6.8V, and the current is basically maintained near 2.6A, the charging efficiency can be guaranteed at around 17W. Here, we still need to spit it out, as can be seen from the photo, the nut R1 lens coating scratches this common problem, we are unfortunate In the middle of the move.
According to our actual measurement, charging is started after the power is discharged to the automatic shutdown. The R1 of 3600mAh takes 1 hour and 1 minute to charge in the power-off state of 0-100. At this time, the mobile phone shows that the power is 100%, and the current is less than 0.5A. In the trickle charge mode, the current gradually decreases and the fluctuation amplitude becomes smaller and smaller.
During the charging process, there is no obvious heat generation on the surface of the mobile phone. Even at the high-speed charging of 17W, the maximum temperature measured by the body is only 35.2 °C. The whole machine can be said to be very cool. This is also a great advantage of QC 4+, charging. The pressure regulation is more precise, which significantly reduces the heat during charging.
At the same time, the temperature of the charging head is 41.5 ° C, and there will be obvious heat when touched. However, because the heat is concentrated on the charging head, it has no influence on the temperature and use of the actual mobile phone. The overall charging experience is still very good. .
Because of the USB-PD fast charge support, the hammer's fast charge also supports the iPhone's fast charge. The iPhone 8Plus can achieve a charging efficiency of about 17W. Compared to Apple's official fast charge set, the price appears. A lot of friendliness, but will not be killed after a certain version of the system update, which we don't know, after all, the iPhone is crazy and even the MFi-certified family has been accidentally injured.
In general, the charging standard is definitely a good thing for consumers, especially the USB-PD supports a wide range of standards, the charging efficiency of up to 100W is even compatible with some thin and light notebooks, for business travelers. In fact, the ability to integrate all the electrical equipment should be regarded as a big dream.
