Review a new charger! Chinese manufacturers have installed Apple mouths on chargers

preface

Previously, the charging head network brought you a very special charger - the use of lightning interface output PD charger, at first glance you may feel a little nonsensical, but for the iPhone, iPad dual machine party, the situation is not the same, go out only a lightning data cable can be charged, no doubt or convenient a lot, the following look at what it can do, the use of lightning data cable can support what kind of PD gear.

Product introduction

This time, under the same interface configuration, QO has launched three products, namely 30W, 33W and 65W.

Compared with the 30W and 65W listed above, it seems that the power density of the 65W version is much higher.

The quality friend 30W charger is printed with the words Sic 30W on the side, using silicon carbide components, which is more efficient and reduces heat, and is also more resistant to high temperatures, and the leaf vein pattern of the embossing is a bit chic.

The pin adopts a foldable design for further portability, while the bottom of the charger is printed with a parameter inscription, the model of this charger is VUA03003-2112, supports broadband voltage input, USB-C and lightning interfaces both support 30W PD output, off the spectrum, USB-A interface up to 30W, dual-port simultaneous output 15W.

The interface part at the top, the function is still very clear, the top is the A port that supports QC, and the interface with two PD outputs below.

The USB-A interface pin is a regular width, and the demo version of the rubber core is a bit crooked.

The other two interfaces are played normally, and there is no special clue.

Product reviews

After introducing the appearance size of the charger, I will take you to see the specific experience of this charger. The charging head network will take everyone to understand this charger from the aspects of compatibility test, charging test, standby power consumption test, etc.

Charging compatibility testing

The compatibility test link can clearly know the charging situation of the charger for each device, and the charging head network will use dozens of devices with the charger for testing, presenting the reader with real test data.

iPhone 13 Pro Max is currently the super cup of the iPhone, charging is also a super cup, itself supports 9V3A 27W fast charging, using USB-C to charge the iPhone 13 Pro Max, the power is 9.16V 2.92A 26.84W.

Charge the iPad Pro with USB-C at 15.19V 1.85A 28.15W.

Charge the MacBook Air M1 with USB-C at 20.23V 1.43A 28.95W.

All the charging compatibility test data are summarized, so that everyone can intuitively understand the charging data of the device.

The histogram section is convenient for users to judge the size of the charge of each device.

Let's take a look at the fast charging compatibility of the USB-A interface.

Use USB-A to charge the Meizu 18 Pro with a power of 9.01V 3.15A 28.43W.

Note that this is the Charger above the Lightning interface, which is commonly known as the Apple Port charging compatibility test.

How to test the Lightning interface to charge the iPhone, after all, there is no lightning fast charging line at both ends, in fact, it is very simple, prepare two C to Lightning fast charging cables, with the help of power-Z tester can successfully charge the iPhone, the power is 8.44V 2.92A 24.7W,

The fast charging cable using the Lightning interface with Lightning to C charges the Samsung S22+ with a power of 8.92V 3.31A 29.61W.

Charge the iPad Pro with 14.72V 1.92A 28.36W.

Charge the iPad Air 5 with 14.71V 1.91A 28.23W.

brief summary

The above tested the USB-C, USB-A and Lightning interface charging compatibility test for everyone, the overall fast charge compatibility is good, the maximum output power of 30W can also meet the fast charge needs of the notebook. And the Lightning interface can also achieve a 30W fast charge output, Lightning reverse output USB-C is still the first time to see.

Multi-port simultaneous output test

Multi-port simultaneous output test can understand the power output of multiple interfaces of the charger at the same time, after all, for multi-port chargers, charging multiple devices at the same time is the biggest highlight.

Use the Lightning connector and USB-A interface to charge two mobile phones simultaneously, with power of 6.33W and 5.37W respectively.

Use the USB-C interface and USB-A interface to charge two mobile phones at the same time, with power of 6.1W and 7.64W respectively.

Why can't you test the output of three ports at the same time? Because the USB-C and Lightning interfaces cannot connect two wires at the same time, they will fight.

From the test situation of multi-port simultaneous output, the multi-port inside the charger adopts the same design, and the single-port output can achieve high-power fast charging, and the dual-port output is 5V output at the same time.

Full test of charging

In addition to the compatibility test, the charger was also collected to charge the device charger for the whole test, this time the choice is to charge the MacBook Air M1, after all, the MacBook Air M1 standard i charger power is 30W.

This is the use of qoyo 30W charger charger to charge the MacBook Air M1 data changes, the whole process is roughly divided into 3 stages, ended in 2 hours and 37 minutes, the maximum power is 20.2V 1.42A 28.81W.

Drawing the whole charging process into a curve, it can be seen that the Quality Friend 30W charger charges the MacBook Air M1 for half an hour to charge 26%, 52% for 1 hour, and it takes 2 hours and 37 minutes to fully charge.

Standby power consumption test

Nowadays, it is the norm for users to use the charger to charge their devices and no longer unplug them from the outlet. Many readers want to know whether the charger is wasted if it is always plugged into the socket, and the standby power consumption test session is to answer this question.

After the power meter test, the charger in 220V 50Hz no-load power consumption of 0.093W, converted to a year's loss of electrical energy is about 0.81KW·h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.486 yuan.

The no-load power consumption at 110V 60Hz is 0.081W, which translates to a year's loss of electrical energy of about 0.7KW·h, and if the market price is 0.6 yuan /KW·h, the charger's annual electricity cost is about 0.42 yuan.

Conversion efficiency testing

A charger is essentially a conversion device that is lost during the process and dissipated in the form of heat. We usually look at the charger above the parameter output 100W or 65W is the maximum output power that the charger can provide for the device, but the charger draws more power from the socket, the following is the charger in the case of 220V 50Hz and 110V 60Hz AC input respectively carried out conversion efficiency test, the test results are as follows.

At 220V 50Hz, the output power of the charger in each voltage gear is fully tested: five gears are measured to measure the input power of the AC terminal of the plug board and the output power of the USB terminal, and the conversion efficiency of the available charger varies from 83.71% to 88.81% through calculation.

At 110V 60Hz, the conversion efficiency of the charger varies from 84.07% to 87.15%.

Ripple test

Due to the switching power supply in the charger, the secondary output of the transformer is not direct current, and it needs to be rectified and capacitor filtered, that is, there will be ripple in the charger output. The charging head network uses an oscilloscope to test the ripple value of the charger output, compare with the national standard, and detect the output quality of the charger. The lower the ripple, the higher the output quality of the charger.

Ripple test is divided into no load (Y axis current in the histogram is 0A) and heavy load (the Y axis current in the histogram is non-0A), which is the ripple test using the charger at 220V 50Hz AC input, the highest ripple when the charger is in the 9V3A output state, 106mVp-p; the lowest ripple when the charger is in the 5V0A no-load state, 52mVp-p.

This is a ripple test using the charger at 110V 60Hz AC input, the highest ripple is 124mVp-p when the charger is in the 20V1.5A output state, and the lowest ripple is 12mVp-p when the charger is in the 9V0A no-load state.

Temperature testing

As mentioned earlier, the charger will involve the problem of efficiency conversion, and the vast majority of the lost power is dissipated by heat, so the heat of the charger working for a long time is also an important part of the test. Let the charger output at 20V1.5A 30W power for one hour continuously, collect the surface temperature of the charger, and place the charger in a 25°C incubator throughout the experiment.

First, let's take a look at the temperature performance of the charger in the mains environment of 220V50Hz.

After 1 hour, the maximum temperature of the two side surfaces of the charger was 78.8 °C when photographed with a thermal imager.

The maximum temperature on the other two sides is 73.3 °C.

Look at the temperature performance of the charger in the mains environment of 110V 60Hz.

After 1 hour, the maximum temperature of the surfaces on both sides of the charger is 71.5 °C when photographed using a thermal imager.

The maximum temperature on the other two sides is 85.2 °C.

1 hour full load stability test

After long-term use, will the charger be reduced due to overheating? The charging head network also tested the Quality Friend 30W charger.

The charger gear is adjusted to 20V1.5A, and the output is continuously output at 30W power for one hour, and the voltage and current are horizontal and straight during the test, without obvious fluctuations, and the use of full load for a long time is also quite stable.

Charging head net summary

After reading the test, are you moved? Measured this charger C port and L port whether the protocol or output are consistent, out of a C2L data cable, iPhone, iPad, Android machine can be charged, really powerful, while having a USB-A interface can also charge the old device.

Because it is a Demo version, there is still room for upgrading in the later stage; and the USB-A interface may be slightly redundant in this set of interface configurations, if the C+L dual-port output version is launched in the later stage, it is a killer.

There have also been rumors that the iPhone will upgrade the USB-C interface, I believe that only the arrival of this day, in order to let manufacturers lose a little hair, so that consumers can truly appreciate the convenience of charging.
