Draw a graph of the whole charging process. It can be seen that this charger charges the MacBook Pro 13 for 34% in half an hour, 67% in one hour, and takes 2 hours and 20 minutes to fully charge.
Standby power consumption test
Nowadays, it is normal for users not to unplug from the socket after charging the device with a charger. Many readers want to know whether the charger wastes electricity if it is always plugged into the socket. The standby power consumption test is to answer this question.
According to the power meter test, the no-load power consumption of the charger at 220V 50Hz is 0.049w, and the electric energy lost in one year is about 0.42kw · h. If the market price is 0.6 yuan /kw · h, the annual electric charge of the charger is about 0.252 yuan.
The no-load power consumption at 110V 60Hz is 0.031w. After conversion, the annual power consumption is about 0.27kw · h. If the market price is 0.6 yuan /kw · h, the annual power charge of the charger is about 0.162 yuan.
Summary
The standby power consumption test is about how much power the charger will consume in a year if it is not plugged into the socket. The lower the value, the better. According to the actual measurement, the realme 65W charger is not used on the socket under the 220V mains power environment, and the electricity charge used in a year is only about 20 cents; However, it is not used in the 110V mains power environment, and the electricity cost used in a year is only about 10 cents. Almost negligible.
Conversion efficiency test
The charger is essentially a kind of conversion equipment. There will be losses in the process, which will be emitted in the form of heat. We usually see that the parameter output of 100W or 65W on the charger is the maximum output power that the charger can provide for the equipment, but the power that the charger draws from the socket is often larger. The following is the conversion efficiency test of the charger under 220V 50Hz and 110V 60Hz AC input. The test results are as follows.
Under 220V 50Hz, pull the output power of the charger at all voltage levels for test: the input power at AC end and output power at USB end of the patch panel are measured at five levels. Through calculation, the conversion efficiency of the charger ranges from 86.88% to 91.52%.
At 110V 60Hz, the conversion efficiency of the charger ranges from 87.59% to 90.15%.
Summary
The conversion efficiency can reflect the quality of the charger. From the data, the higher the percentage, the better. It can be seen from the above test data that the efficiency in some output gears has reached more than 90%, which is in the front of the camp of some high-power PD chargers. Lenovo's high-power fast charging of chargers is aimed at charging laptops. For users, the most intuitive feeling is that the efficiency of charging laptops is high, and the heating is naturally low.
Ripple test
Since the charger uses a switching power supply, the secondary output of the transformer is not DC, which needs to be rectified and capacitor filtered, that is, the charger output will have ripple. The charging head network uses an oscilloscope to test the ripple value output by the charger, and compares it with the national standard to 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 (Y-axis current in the histogram is non-0a). No load part: under 220V 50Hz AC input, the charger has the highest ripple of 100mvp-p when it is in 5v0a no-load state; Under 20v0a no-load state, the ripple is the lowest, 26mvp-p.
Under 110V 60Hz AC input, when the charger is in 5v0a no-load state, the ripple is the highest, which is 76mvp-p; Under 20v0a no-load state, the ripple is the lowest, 20mvp-p.
For the heavy load part, the charger has the highest ripple of 80mvp-p when it is in 5v2a output state under 220V 50Hz AC input; When in 15v2a output state, the ripple is the lowest, 38mvp-p.
Under 110V 60Hz AC input, when the charger is in 20v3.25a output state, the ripple is the highest, which is 82mvp-p; In the 12v2a output state, the ripple is the lowest, 36mvp-p.
Summary
The lower the ripple value, the higher the output quality of the charger. From the test data, the ripple value of the whole charger is relatively low, indicating that the output quality of the charger is very high.
Temperature test
As mentioned above, efficiency conversion is involved when the charger works. Most of the lost power is dissipated by heat, so the heating condition of the charger working for a long time is also an important part of the test. Let the charger output continuously at 20v3.25a 65W 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 220V50Hz mains environment.
After 1 hour, the maximum temperature of the two side surfaces of the charger photographed by the thermal imager is 62.7 ℃.
In addition, the maximum temperature on both sides is 63 ℃.
Take another look at the temperature performance of the charger under the 110V 60Hz mains power environment.
After 1 hour, the maximum temperature of the surfaces on both sides of the charger is 65.4 ℃.
In addition, the maximum temperature on both sides is 68 ℃.
Summarize the temperature data for easy viewing. The four temperature data are between 60 ℃ and 70 ℃. The maximum temperature is 68 ℃ and the minimum temperature is 62.7 ℃.
Summary: more than realm 65W charger supports private fast charging and 65W PD fast charging, and the data in the temperature test with 65W full load output for 1 hour are all below 70 ℃. However, if large electric equipment such as notebook computer is configured in daily life, it will not continue to charge with 65W full load power, and the power will decrease with the increase of notebook power. Therefore, it is believed that the temperature in daily use will be lower than that in the test. 60 ℃.
In terms of performance, the charger supports a maximum output power of 65W. As a standard charger for realm notebook computers, it actually supports the private fast charge of oppo series. In addition, it is compatible with 65W PD fast charge and a wide range of PPS fast charge, which also makes it very compatible with other mobile phones. It can provide up to 65W charging power for notebooks and nearly 50W for some mobile phones, This is still very rare in the standard charger of notebook at present.
In addition, for the points that users can't see, they have also been added to the test this time. Whether it is the standby power consumption, conversion efficiency and ripple of the charger, the charger of realm performs very well. In terms of temperature, the test under the limit condition of 65W full load output for 1 hour is above 60 ℃. Just as the limit test mentioned above, it is believed that the temperature will be lower than the test temperature in daily use.
Charging head network Summary
Realm 65W charger is not very special in appearance design. The white bright surface shell is simple and elegant, and supports qc3.0, qc4+, pd3.0, PPS and other fast charging protocols. In the compatibility test, it can meet the fast charging demand for mainstream mobile phones and tablets, but it is slightly insufficient for notebook computers with large power demand.
In terms of performance, it takes 2 hours and 20 minutes for the realm 65W charger to fully charge the MacBook pro13, which is comparable to Apple's own charger. If it can be purchased, it must be one of the most popular alternatives. At 220V 50Hz, the conversion efficiency of the charger is between 86.88% and 91.52%, resulting in lower heating capacity. The average temperature of the test full load is not more than 70 ℃, and the quality is not sold in the market( https://microsoft.pvxt.net/Xx07X ) Manufacturer.
Finally, during the test, the voltage and temperature of realm 65W charger are relatively stable during long-time charging, and the ripple is relatively gentle. The long-time charging output will not cause equipment damage. For the attached charger, the quality belongs to the first echelon.
