preface
Recently, Huawei Mall listed a 25W power mini charger kit, everyone knows that Huawei has 22.5W fast charging, where did this 25W pop out? However, when you see its USB-C interface, I am afraid that you will know a rough idea - it is a PD charger, and it is compatible with Huawei's own protocols.
At the same time, this charger set comes with a 3.3A C2C cable, which looks a bit strange. So how to use it, the compatibility of the third party is good or not, the following will tell you about it.
Product out of the box
The packaging states that it supports HUAWEI SuperCharge.
Open the package and include the charger, charging cable and instruction manual.
The charger body is a bright flame retardant plastic with a top cover on the interface surface.
The side of the charger also has the words 25W HUAWEI SuperCharge.
The plug head is divided into two feet national standard plug, non-foldable design, with better weather resistance.
The interface surface of the charger is a single USB-C output interface, and there is the HUAWEI logo below.
The USB-C mother-mounted rubber core is a familiar purple color, indicating that it supports Huawei fast charging.
The bottom is also printed with parameter information, this charger model is P0011, supports broadband voltage input, but in a voltage environment of 110V, the maximum output power is 18W, and in a 220V voltage environment, the maximum output power is 25W.
The height of the charger is about 32.04mm.
The length of the charger is about 31.89mm.
The width of the charger is about 31.88mm, the size of the charger is about 32.04×31.89×31.88mm, the volume is about 32.57cm, and the power density is about 0.76W/cm in terms of the power of the charger's power of 25W.
Compared with Apple's 20W charger.
The interface surface of the charger is compared with the one-dollar coin.
The unit weight of the charger is about 38.7g.
In the hand, portability is still good.
The included charging cable is configured for the C2C interface.
The terminal shell is injection molded, and the word 3.3A is printed at the end of the line, which naturally does not have an E-Marker chip.
The length of the wire is about 102cm.
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 QC2.0, QC4, FCP, PD3.0 and PPS.
In terms of PDO messages, it supports three sets of fixed voltages of 5V3A, 9V2.78A and 12V2A and 3.9V-5.9V3A and 3.9V-11V2.25A, which has better equipment compatibility.
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.
Charge the Huawei Mate40 Pro with a charger of 8.38V 2.47A 20.77W.
Charge the iPhone 13 Pro Max with 8.94V 2.66A 23.81W.
Charge the Huawei P40 Pro with a power of 8.49V 2.38A 20.25W.
Charge the iPad Air 4 with 8.7V 2.59A 22.57W.
Charge the MacBook Air M1 with 8.7V 2.51A 21.92W.
Aggregate compatibility test data into tables for easy viewing.
The histogram can clearly see the level of charging power of the device.
Full test of charging
Since it is Huawei's charger, the charging process test naturally chooses to charge the Huawei mobile phone, and this time the choice is to charge the Huawei Mate40 Pro to see the measured data.
This is the data of the whole process of charging the Huawei Mate40 Pro using the Huawei 25W charger, the whole process is roughly divided into 2 stages, and the charging ends in 1 hour and 10 minutes, with a maximum power of 8.77V 2.46A 21.66W.
Comparing the curve of Huawei's 22.5W and 25W chargers charging Huawei Mate40 Pro together, 25W is faster than 22.5W overall, which is also logical.
Among them, at half an hour time point, the 22.5W charger charges 51%, the 25W charger charges 55%; at the 1-hour time point, the 22.5W charger charges 90%, and the 25W charger charges 97%; the fully charger 22.5W takes about 1 hour and 21 minutes, and the 25W charger takes about 1 hour and 10 minutes.
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 0.085W, converted to a year's loss of power of about 0.74KW·h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.44 yuan.
The no-load power consumption at 110V 60Hz is 0.041W, which translates to a year's loss of electrical energy of about 0.35KW·h, and if the market price is 0.6 yuan /KW·h, the charger's annual electricity cost is about 0.21 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 three gears, and the conversion efficiency of the available charger varies from 83.78% to 87.7% through calculation.
At 110V 60Hz, the conversion efficiency of the charger varies from 83.2% to 86.55%.
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, 56mVp-p; the lowest ripple when the charger is in the 12V0A no-load state, 38mVp-p.
This is a ripple test using the charger at 110V 60Hz AC input, the highest ripple is 88mVp-p when the charger is in the 5V3A output state, and the lowest ripple is 24mVp-p when the charger is in the 12V0A no-load state.
Charging head net summary
As the lite version of Huawei's fast charging family, this 25W charger uses USB-C output, fast charging does not require the use of a dedicated data cable, of course, a 3.3A data cable is also included, which is convenient for users to use out of hand.
The fast charging protocol is the highlight of this product, in addition to supporting its own FCP protocol, it is also compatible with QC, PD, PPS and other protocols. With the blessing of these protocols, this 25W charger has a good power performance whether it is an iPhone or An android. For Huawei users, this may be the most portable original charger available.
