preface
Previously, the charging head network for everyone to evaluate, disassemble a lot of notebook PD chargers from DELL, these chargers without exception use an extended power cord design, and non-removable charging cable, single USB-C output, and the terminal left an LED charging indicator, quite intimate. Of course, the workmanship is not much, all come from the large factory OEM.
The DELL 60W PD power adapter brought to you this time is different from the past, canceling the fixed charging cable design, which greatly facilitates the user to replace the cable and maintenance in the later stage, the LED indicator has also been retained, the power density is about 0.75W/cm, and the small volume is more portable. How compatible is it? This is a review for everyone.

The width is approximately 55.04mm.
The thickness is about 22.11mm, the size of the adapter is 65.93×55.04×22.11, the volume is 80.23cm, according to 6
W power calculation, power density of about 0.75W / cm, performance in the same series of chargers is considered to be amazing.
The weight is about 101.3g.
In the palm of my hand, this time I finally took advantage of it a lot.
Product reviews
After introducing the appearance and size of the DELL 60W PD power adapter, we will take a look at the specific experience of this charger. The charging head network will take everyone to understand this charger from the aspects of protocol test, compatibility test, charging test, standby power consumption test, etc.
Product performance evaluation
In terms of protocol, the use of ChargerLAB's POWER-Z KT002 to read the charger's fast charging protocol, the actual test supports PD charging protocol, after all, it is the adapter of the notebook,
In terms of PDO messages, it supports four fixed voltages of 5V3A, 9V3A, 15V3A and 20V3A.
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 iPhone 13 Pro Max with approximately 9.24V 2.92A 27.04W.
Charge the Nubia Z30 Pro at approximately 9.24V 2.88W 26.61W.
Charge the MacBook Pro 16 at approximately 20.38V 2.83A 57.86W.
Powering the Switch TV base, tv mode was successfully triggered with a power of about 5.69W.
Charge the Mijia hand drill, the power is about 5.29V 2.89A 15.32W.
Charging the Fico shaver, the device is not recognized, tested because the shaver does not support the PD quick charge input.
Organize the data into tables and the charger compatibility is quite good.
The charging power is sorted from high to low, and the histogram is made to make a histogram to intuitively compare the difference in charging power between different devices.
Full test of charging
Charging the whole test can clearly see the changes in the parameters during the charging process, this time the model used is MacBook Pro 16 2021, to see the data changes in the whole process of charging.
The whole charging voltage is maintained at about 20V, 1 hour and 30 minutes before charging, the power is about 57W, and then the power is reduced to 47W, which lasts until 1 hour and 46 minutes, and then enters the trickle charging mode, which takes 2 hours and 34 minutes.
The charging data is sorted into a graph, the charger charges 26% of the notebook in half an hour, and 52% of the charge in one hour, and the whole process takes 2 hours and 34 minutes.
Standby power consumption test
If the charger is often plugged into the socket and not used, it will consume power, but it is very small. 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 0.119W, converted to a year of loss of electrical energy is about 1.042KW·h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.62 yuan.
110V 60Hz no-load power consumption of 0.012W, converted down, a year of loss of electrical energy is about 0.105KW·h, if the market price is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.06 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 power from the socket is often larger, 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 90.01% to 93.74%.
At 110V 60Hz, the conversion efficiency of the charger varies from 90.37% to 92.74%.
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.
This is the use of charger at 220V 50Hz AC input ripple test, 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 not 0A) two, the highest 76mVp-p charger is at 5V0A no-load, the lowest 28mVp-p charger is at 15V2A output.
At 110V 60Hz, the maximum is 84mVp-p, and the charger is at 5V0A no load, and the minimum 16mVp-p charger is at 9V2A output.
Ripple test summary
The charger ripple requirement in the national standard is not higher than 200mVp-p, DELL 60W PD power adapter in 110V 60Hz, 220V 50Hz input voltage, all output power ripple peak-to-peak are lower than 200mVp-p this standard, good performance.
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. The charger is continuously output at 60W power for one hour, the surface temperature of the charger is collected, and the charger is placed 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 one hour, the maximum temperature of the charger front is 55.6 °C.
The maximum temperature on the back of the charger is 56.2°C.
Look at the temperature performance of the charger in the mains environment of 110V60Hz.
After one hour, the maximum temperature of the front of the charger is 65.3 °C.
The maximum temperature on the back of the charger is 60.2°C.
Charging head net summary
The APPEARANCE OF THE DELL 60W PD POWER ADAPTER CONTINUES THE LOW-KEY BUSINESS OF ITS PREDECESSORS, WITH A ROUND BLACK MATTE CASING, OEM BY QUNGUANG. However, this time, the unusual did not use a fixed charging cable, a single USB-C output interface, and moved the LED indicator to the front of the charger.
In terms of performance, as a pure PD charger, the DELL 60W PD power adapter charges a variety of devices, and the input power is normal. Moreover, under the small size of the power density of about 0.75W/cm, the surface temperature of the one-hour full power output is only 50 or 60 degrees, which shows that the material is solid.
