Two straightforward hair pian objects were sent directly to the sun, which made me feel a bit embarrassed.... So behind the first sun or find something to test more than test a test, content full and full Some, @ original small value, we must pursue progress One, gossip fast charge I remember that the mobile phone was charging 5V 500mA earlier in the year.... There is an 800mA 4W charger that counts as “fastâ€, and 11 years later the 5V 1A/5V 1.5A/5V 2A/5V 2.4A will soon be on the tablet. Field popularity At the end of last year, QC3.0 formally followed the launch of a new Qualcomm chip: So in the end QC3.0 has changed more than QC2.0? Qualcomm officially declared: Quick Charge 3.0 can charge a typical cell phone from zero to 80% in approximately 35 minutes. Traditional mobile terminals that do not have Quick Charge typically take about one and a half hours. Compared to two generations of products: 1. Compared with Quick Charge 2.0, it can increase the fast charging speed by up to 27%, or reduce the power loss up to 45%. 2, 2 times faster than Quick Charge 1.0 charging speed. Simply speaking, for our customers, we can get faster charging speed and be more energy-efficient (reducing power consumption not only means saving electricity, but also means lowering the heat generated by the charging process). Another important point is that 3.6V-20V (most of the current mobile phones The use of 5-12V range, 20V to estimate the multi-level segmentation of tablet applications, this is actually an important reason to obtain the advantages of the previous, but the greater significance is that this feature can help us to determine a charging product is QC2.0 or QC3.0, if there is only 5V 9V 12V such a three-speed voltage charging products, then it certainly will not be QC3.0 products. As for 35 minutes full of 85% ... ... foreigners publicity is also like this .... depends on the battery capacity and is 12V 2A charge or 9V 1.8A, 5V 2A, a lot of speed difference Other rapid flushing technology: MTK MediaTek Pump Express , technical information is more complex and there is not much popular explanation, but the effect is similar to QC3.0. According to published data, it is composed of a power management IC and a DC wall charger built into the PMIC. Pump Express features: In fact, MediaTek and Qualcomm's fast charging technology is fundamentally the same. Basically through the coordinated increase of voltage and current to achieve a faster charging speed than the average charger, but overall QC3.0 performance and technology are better. OPPO VOOC flash charge , now is a fire plus 3 DASH flash charge is also this, unlike the above two to increase the voltage automatically dispatch voltage and current, VOOC flash red using 5V low voltage but increase the current to achieve fast charging purposes, The advantage is that the loss power consumption is lower than the former two (the energy loss during buck-boost is relatively large), so the heat is lower when fast charging, and therefore, even if you open the screen and use the edge charge, you can maintain fairly fast. The charging speed spikes Qualcomm and MTK; the defect is that the charging head and the mobile phone plug interface and data line have additional contacts and channels, and you can only use the original charger and data cable while achieving the terror input of 2 times the conventional current of 5V 4A. In order to achieve the ideal fast charge effect.... Second, ORICO QS1 mobile power out of the box: This mobile power packaging specifications do not label any QC3.0 information, but look at other people's test is to support QC3.0 so start, the old millet car mobile power does not support fast charge slower is on the one hand, mainly There is a handy coupon available to start with a beautiful price, and you can come to Zhang Aunt’s first sun, why not? 1, the front of the box, two colors, the wife said not to pink .... so I bought silver, so we need to be able to bring, but I think the physical should be called Mocha gold better: 2, the back of the package: 3, consider the aunt's house thumbnail can not see, grasp the local information: the input does not indicate support for QC3.0, but the actual support ...; output specifications do not see the characteristics of QC3.0 .... but in fact It is also true 4, 18650 batteries, see others dismantling that Samsung 3350mah three sections, that is, 10050mah, but the box marked 10500mah (but see other people out of the box is 10050mah. Do you have a few kinds of packaging?), and some specification table also identified 10400mah ( Should be the capacity of the previous generation QC2.0), this ORICO really feels a bit of a hectic, of course, said that mAh is rogue, because there is no sense what voltage does not indicate, focus on Wh, is the real capacity, on the body Mark 5, side package also take a look: 6, family portrait: 7, bag tear, manual development: 8, interface identification: 9, charging line length is moderate, not hard, more portable: 10, body front, this can not be called silver gray it .... have LOGO: 11, there is no back: 12, the bottom of the specification table, and finally from here to see the correct label of 10050mah, and accurate 37.2wh capacity, QC3.0 specification verification, output 5-6V 3A, 6-9V 2A, 9-12V 1.5A, and input also Supports 30W charging up to 12V 1.5A, true bi-directional fast flush: 13, the interface part, the charging in port uses the MicroUsb port, its realization in the Type-C popular, made TPYE-C mouth better, otherwise the new Android phone also has to bring two lines ... right OUT USB port, left Side switch button, insert the charging device to start charging when pressed, 4 lights indicate the power: 14, Virgo may be entangled a little, that is, after inserting the charging line there are LOGO's mobile power supply and LOGO's data cable connector is not in one side ... This is the details of the problem is worth improving: 15, the weight of 212.6g, than the old 10000mah millet mobile power 5g, than the same two-way fast-moving millet mobile power supply with high light 11g. Second, insert the sun appearance off the guest WIFI socket Because this is a lot of Aunt Zhang sun drying, WIFI part of the evaluation, hurriedly drying out of the box: 1, packaging: 2, internal: 3, family portrait: 4, the back of the details: 5, the indicator part: 6, USB charging part: 7, plug: 8, used to test the charging speed of mobile power charger, PS, I tried several chargers at hand can not be 12V handshake, but there are users testing "Tianhao series chip charger can successfully shake hands with this power 12V", Fortunately, 9V 2A is generally fast enough Third, the mobile power evaluation section 1, no load 5.19V 2. After charging the point of the mobile power source, the charging starts at about 9.01V 1.5A 13.6W, and then slowly increases to about half of the charge. The current has risen to about 1.73A, and the charging power has reached 15.66W: 3. Nearly 95% of the time is close to 3 hours. Turbulence is about 0.67A: 4, then go out once and come back to miss the point, QC2.0 9V is full of about 4 hours or so estimated, power consumption 44.026Wh, lower than the efficiency of the QC3.0 test on the Internet others: 5, insert millet 5 with high, put screen charge 5.83V 2.47A, has been in QC3.0 mode: 6, a plus 3 + DASH line, no accident, because VOOC flash red closed, does not support .... only 4.93V 1.44A full speed, so OPPO, a plus 3 users want to have VOOC / DASH flash The effect of rushing to buy OPPO expensive mobile power it, but the OPPO mobile power on a small capacity, right? 7, music as 1S, MTK fast-paced program, put screen 11.8V 1.49A: Under the bright screen reached 11.8V 1.86A, mobile power fire full open: 8, QC2.0 LG flex II, put screen 8.9V 1.13A, bright screen 8.89V 1.41A: 9, try a small current product, fly proud mini portable sports M3 player, 5.04V 0.3A: 10, Plantronic Bluetooth headset, 5.06V 0.09A: 11, millet bracelet 5.07V 0.02A, but to illustrate the ring when the current is too small, after a while the mobile power supply will be considered fully charged and automatically cut off the charge, this is probably the millet high match has a special optimization of the match: 12, while the edge of the test, because the fast full, plug in the 5V 2.4A only 5.19V 0.53A current Insert one plus three and music as the phone test, the input is changed to 5.07V 1.74A, very stable, while charging the mobile power, mobile power is also normal to charge the phone, would also like to test 9V charger under the current test phone. .... But because IN, OUT can't plug in the charging line and tester at the same time, so give up: 13, ipad mini2 screen charge 4.91V 1.69A 14, ipad mini2 bright screen charging 4.9V 1.83A: 15, with 9V output to Flex2 charge 52% of the electricity, but also to ipadmini2 5V output from the empty charge to more than 70%, the final output power of about 31.5Wh, the mixing efficiency of about 85%, because there is a part of the high voltage charging efficiency is affected Fourth, summary. QC3.0 mobile power double-sided fast-rushing is not yet available in the market, in addition to mobile phone brand manufacturers out of their own little, and in addition to high prices with millet have a certain virtual high, ORICO this price to 199 yuan, cost is not High, if not the Tmall VIP card I may not be able to purchase large coupons, as 18650 lithium battery and lithium polymer batteries who have a long history of disputes, but in fact have their own advantages and disadvantages, large Can not entanglement, choose the mobile power is the most important brand quality, capacity, price, charge and discharge speed, efficiency, many people may also put the value in front. This mobile power set aside price, shell material feel and color value is also good, two-way support QC3.0 fast red (QC3.0 verification trigger board can be used about 7V10V charge and discharge), conversion rate compliance, weight moderate case Narrow and easy to carry, calculate the middle distance, but comprehensive consideration of the official price factor must be inferior to millet 10000mah high, the original price to buy the belief ....
