preface

In the era of mobile Internet, more and more smart phone and tablet users have become a leader. In many cases, once a day charging can no longer meet the use requirements. For example, Xiao Feng uses mobile phones because QQ , WeChat, video, Bluetooth, various app , plus two Hourly games and so on. One charge at noon, one charge in the evening, and one charge in sleep are common. The battery life of intelligent products is limited, and how to charge quickly anytime and anywhere when the power is insufficient has become the focus of many manufacturers. For example, Qualcomm's fast charging technology Quick Charge , currently from two Upgrade to three More and more mobile phone manufacturers and power supply manufacturers have adopted and launched corresponding products, such as ORUCO Qrico Fast charging series of mobile power Desktop QC2.0 Charger 、 QC3.0 On board charger Three products.

Xiao Feng has also used Qrico's socket, laptop cooling pad USB Fans and other products, the packaging style of their product lines is consistent with the white style, simple based. The three products are no exception, except QC3.0 In addition to the product pattern on the front of the mobile charger, the other two products are only products on the front logo 。

Mobile power fast charging version

From the parameters on the back of the packing box, we can know that the input parameters are DC5V/2.1A , the output parameter is DC5V/2.1A  9V/1.8A  12V/1.35A , battery capacity 10400mAh(37.44Wh) , which can meet the charging requirements of different terminal devices.

The mobile power supply in the packaging box is wrapped in a plastic bag and placed on the paper base, and the left one shows the product support with a pattern 5V/9V/12V Fast charging. The internal power cord is very short. It is estimated that the manufacturer is only for users to charge the mobile power. After all, users have their own power cord, and now the interface is slowly changing from Micoro USB towards Typc-c Transition.

The mobile power supply is designed with frosted aluminum alloy shell, and the metal material can improve the product taste and also be more conducive to heat dissipation; From left to right on the top are the power key, power indicator Micoro USB Input interface USB Output interface; The bottom is the product parameters, which are consistent with those on the packaging box. Xiao Feng judges that the inside is four section eighteen thousand six hundred and fifty Cell, rated capacity 2600mAh 。

Similar products ANKER QC2.0 Mobile power supply, its battery capacity 10050mAh But the appearance will be better than Qrico Is smaller. It should be three sections eighteen thousand six hundred and fifty Cell, rated capacity 3350mAh , its weight 237.9g and Qrico Of two hundred and eighty point five It is also normal.

Xiao Feng uses LeEco two Mobile phone, support 3.6V~8V=3.0A/12V=2.0A Fast charge input, Use separately Qrico and ANKER Fast charging mobile power to charge mobile phones Use software to record the charging process, but there is no way to ensure that the phone will not be used during the charging process, so it is not possible to judge which product has faster charging effect based on the charging time of the whole process, and compare it from a point of time when it is not used, such as using Qrico from 75% reach 83% charge 8% Spent ten branch twenty-eight second , using ANKER from 76% reach 83% charge 7% Spent nine branch thirty-nine Second, the charging speed of the two is about the same. use Qrico mobile power fast charging version charges, charging speed is good.

Qrico Mobile power fast charging version Empty the battery first, then charge it and use USB at the same time Voltammeter for test , measured input when fully charged 9015mAh ; then use it to charge the mobile phone until the cumulative output is 4227mAh ， The actual conversion rate is 46.89% 。

Carry out the second charge and discharge test, and use different brands of USB The voltmeter and ammeter are tested, and the cumulative input power of mobile power supply is 8803mAh , cumulative output power is 3571mAh , the actual conversion rate is 40.57% . After two tests Qrico The charging and discharging efficiency of fast charging version of mobile power supply is very low.

Desktop QC2.0 Charger

From the parameters on the back of the packing box, the output parameters are one × QC2.0( 5V=2.4A/9V=2A/12V=1.5A) 、 four × Super Charger( Single port 5V=2.4A) , total output 5V=8A 40W MAX 。

The charger in the packaging box is protected by a plastic bag, and there is also a two Hole power cord, equipped with cable tie, suitable for travel storage.  

The front of the charger is a black panel with only products on it logo The lower part of the gray back is the product parameters and manufacturer information, which is consistent with the packaging box.

The top side is two Jack power cord jack, the bottom side is evenly arranged five hole USB Charging port, the left side is support QC2.0( green ) , the rest four Hole support Super Charger( High speed charging )。

Qrico desktop QC2.0 Charger And Anker 6 mouth USB Charger Conduct appearance and interface comparison, and the net weight is 156.3g Of Qrico Specific net weight is 195.4g Of Anker More portable.

Use separately Qrico and ANKER The process is the same as that of mobile power test Qrico from 70% reach 77% charge 7% Spent ten branch thirteen Seconds, use ANKER from 62% reach 69% charge 7% Spent eight branch thirty-seven Seconds, actual fast charging effect Qrico Slightly inferior to ANKER , but it has little impact on ordinary users.

use Qrico Desktop QC2.0 Charger to Qrico Mobile power fast charging version for charging and experience separately QC2.0 Output interface Super Charger Charging effect of output interface, using USB The data measured by the voltmeter and ammeter are 8.77V=0.96A and 5.06V=0.84A , the actual output effect of fast charging will be affected by the instrument, and the operating temperature measured during charging is thirty-eight point four ℃, the working temperature will be slightly higher, but it is also within the normal range.

QC3.0 On board charger

Compared with the other two models, the packaging box of this product is the only one with product design printed on the front, and QC3.0 Charging technology ratio of QC2.0 More advanced, the charging speed is improved and the heating capacity of the charging equipment is greatly reduced.

This product does not have a supporting power cord. The charger has a mirror black plastic appearance. Its shape is the same as that of common car chargers. The front is the product logo , with Qualcomm on the back (Qualcomm)QC3.0 The mark of charging technology shows the output parameters of three charging ports respectively below: QC3.0 、 5V2.4A 、 5V1A , respectively corresponding to three charging interfaces at the charging end, of which orange represents QC3.0 Distinguished from the common interface, there is also a power indicator hole in the lower middle of the charging end. If you are not careful enough, you will not notice it.

The car charger is easy to use. You can use it by unplugging the cigarette lighter and plugging it in. The power indicator light will be blue when you use it at night.

It is also used to charge the mobile phone USB The voltmeter and ammeter are tested QC3.0 The charging interface output is 5.22V=1.47A ， 5V2.4A The actual output of the charging interface is 5.17V/0.71A The charger is used to output the voltage and current that can be accepted by the charged equipment through intelligent judgment USB Voltammeter influence.

no need USB Voltammeter, which directly charges the mobile phone, can be seen from the record history of the software 79% reach 87% charge 8% Spent eight branch forty-four Second, considering the factor that the charging speed gradually decreases with the increase of the remaining power ( For example, the previous article Qrico Desktop QC2.0 Charger from 70% reach 77% charge 7% Spent ten minute thirteen second ) ， QC3.0 The charging speed of QC2.0 Come on.

summary

Endurance is always the era of smart terminal pain, Qrico As a manufacturer focusing on charging equipment, we have carefully researched and developed corresponding solutions for different needs, which are medium in terms of convenient price and suitable for users.

deficiencies: one The mobile power supply has a false label; two The conversion rate of mobile power is very low (although this is a common problem in the industry, 40.57% is really too low).
