Samsung S22 series 45W charger out of the box: 299 yuan expensive outrageous

preface

Not long ago, the Samsung S22 series mobile phone that supports the highest charging power of 45W has met with everyone.

Among them, all the series canceled the charger, and the strategy of attaching a 3A charging cable really made Samsung fans feel cold. Fortunately, Samsung mobile phones for PD compatibility is very good, it is not difficult to buy a third-party charger, just support ppS protocol, power greater than 40W, with 5A charging cable has a good performance.

For the original accessories party, Samsung has also updated the 45W charger set for everyone to buy, this is the product of this time, come to see if the 299 45W charger is worth this price.

Unbox

The charger body is made of black matte material, and the top cover and housing are spliced together.

Open the package, charger, charging cable and instruction manual a lot.

The charger has the words Super Fast Charging printed on the side, and it seems that Samsung feels that Fast is not enough to describe this 45W.

The pin part is fixed design, and the national standard double-ended plug.

The USB-C output interface is designed at the top.

The side of the charger is printed with a parameter inscription, this charger is the model EP-T4510, supports broadband voltage input, the maximum output is 45W, and Samsung Electronics is made in Vietnam.

The height of the charger is about 47.51mm.

The length of the charger is about 43.64mm.

The width of the charger is about 27.87mm, the size of the charger is about 47.51×43.64×27.87mm, the volume is about 57.78cm, calculated by the charger power of 45W, the power density is about 0.77W/cm, and it is still possible to do well, Samsung.

Compared with Apple's 30W charger, the power of 45W is also a lap smaller.

The charger is about the same width as a one-dollar coin.

The unit weight of the charger is about 98.1g.

Compare to the previous 45W

Compared with the previous generation of 45W chargers, the front face looks smaller.

The parameters on the back are not bad, the EP-TA845 also does not support 12V output, and the PPS gear part is slightly different.

The volume difference between the side contrasts is obvious.

Charging cable

The included charging cable is configured for the C2C interface, which is different from the 3A cable that comes with the S22, and is obviously thicker than a turn.

Plastic frosted terminal shell is printed with the word 5A, USB-C terminal male head is slightly residual, this era also uses splicing plugs, this cost also has to be deducted.

The length of the charging cable is unusual, reaching 181cm.

Using the POWER-Z KM002C measurement cable chip, the E-Marker is built-in, supports 100W PD charging, and the data transfer specification is USB2.0.

Protocol testing

This test module mainly tests the charger's fast charging protocol, and the user can match the output device according to the specific protocol, so as to obtain a better fast charging experience.

In terms of protocols, ChargerLAB's POWER-Z KT002 reads the charger's fast charging protocol, and the actual test supports charging protocols such as QC4, PD3.0 and PPS.

In terms of PDO messages, it supports five sets of fixed voltages of 5V3A, 9V3A, 15V3A and 20V2.25A and three sets of PPS voltage files of 3.3V-11V5A, 3.3V-16V3A, 3.3-21V2.25A, which have better device compatibility.

Product reviews

Next, 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.

Charge the Samsung S22+ with a Samsung 45W PD charger with a power of 9.08V 4.26A 38.74W.

Using a Samsung 45W PD charger to charge the iPhone 13 Pro Max, the power is 9.01V 2.92A 26.39W, which can already meet the fast charging needs of the iPhone 13 Pro Max.

Switch base TV mode supports PD fast charging, but if you want to activate the base TV mode, you need the PD charger to support 15V3A and above PD fast charging gear, that is, the charger must support 45W fast charging at least. Using the Samsung 45W charger to power the Switch Base TV mode, the charger output power is 14.72V 0.31A 4.65W, successfully lighting up the Base TV mode.

All the charging compatibility test data are plotted, so that everyone can intuitively see the fast charging data.

The histogram section can clearly see the size of the fast charging power of each device.

Full test of charging

Samsung's 45W gallium nitride charger is suitable for Samsung's mobile phones, so this time chose to charge Samsung's latest Samsung S22+ for charging test, the following is the measured data.

This is the use of Samsung 45W Gallium Nitride charger charger charger to charge Samsung S22 + data changes, in 3 minutes and 48 seconds before the input power of about 37W, and then the power and current began to fluctuate between 8W-37W, 47 minutes of power and current gradually decreased until the end of charging, the whole process took about 1 hour and 27 minutes, the highest power is 9.25V 4.22A 39.05W.

This is a comparison chart of the charging curve of charging Samsung 45W Gallium Nitride charger, Samsung 45W charger and Samsung 25W charger to Samsung S22+.

At half an hour's time point, 63% of the 25W charger charged, 66% of the 45W charger charged, and 57% of the 45W Gallium nitride charger charger;

1 hour time point, 25W charger charging 96%, 45W charger charging 96%, 45W Gallium Nitride charger charging 93%;

Fully charged, the 25W charger takes about 1 hour and 21 minutes, the 45W charger takes about 1 hour and 18 minutes, and the 45W Gallium Nitride charger takes about 1 hour and 27 minutes.

Samsung 45W Gallium Nitride charger in addition to supporting Samsung 45W fast charging, but also compatible with 45W PD fast charging, 45W this power band can just meet the charging needs of MacBook Air, so this time also tested for MacBook Air charging.

This is the data change of the whole process of charging macBook Air M1 using Samsung 45W Gallium Nitride charger, the whole process is roughly divided into 4 stages, and the charging ends in 2 hours and 15 minutes.

The whole process of charging is drawn into a curve chart, and it can be known from the curve chart that half an hour of charging 38%, 1 hour of charging 68%, and it takes 2 hours and 15 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 0.051W, converted to a year's loss of power of about 0.44KW·h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.264 yuan.

The no-load power consumption at 110V 60Hz is 0.027W, which translates to a year's loss of electrical energy of about 0.23KW·h, and if the market price is 0.6 yuan/KW·h, the charger's annual electricity cost is about 0.138 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: the input power of the AC terminal of the power strip and the output power of the USB terminal are measured in four gears, and the conversion efficiency of the charger is calculated from 87.42% to 89.97%.

At 110V 60Hz, the conversion efficiency of the charger varies from 87.06% to 90.8%.

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 5V3A output state, 222mVp-p; the lowest ripple when the charger is in the 15V0A no-load state, which is 76mVp-p.

This is a ripple test using the charger at 110V 60Hz AC input, the highest ripple is 146mVp-p when the charger is in the 5V2A output state, and the lowest ripple is 66mVp-p when the charger is in the 15V0A 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 20V2.25A 45W power for one hour, 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 is 61.1 °C when photographed using a thermal imager.

The maximum temperature on the other two sides is 59.8 °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 62.8 °C when photographed with a thermal imager.

The maximum temperature on the other two sides is 66.7 °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 Samsung's 45W Gallium nitride charger.

The charger gear is adjusted to 20V2.25A, with 45W power continuous output for one hour, the voltage and current during the test are horizontal and straight, there is no obvious fluctuation, and the use of full load for a long time is also quite stable.

Charging head net summary

Samsung's new 45W charger modeling is no surprise, as always, the black is not slippery, fixed pins, USB-C output interface, but the power density has been significantly improved compared with the previous generation, to 0.77W/cm, the carrying experience is much better, and the length of the 1.8-meter charging cable is absolutely enough.

In terms of performance, even its own AFC fast charging protocol is not supported, QC4, PD3.0 and PPS and other charging protocols support, so that the compatibility performance of this charger is quite stable, multi-file PPS variable voltage support, so that it with Samsung S22 series mobile phone fast charging without pressure, do not care about the price of the original party first choice.
