Charging evaluation
Let's take a look at thisportable sourceThe charging head network will give you a comprehensive understanding of this model in terms of charging compatibility test, input whole process test, output efficiency test, etcportable source。
Charging compatibility test
During the compatibility test, you can clearly know the charging status of the charging bank for each device. The charging head network will use more than a dozen devices with chargers to test, presenting the real test data to the readers.
Type-C
Connect the MacBook Pro M2 2022 to the Type-C port of the 35W 20000mAh power bank, and use the POWER-Z KM003C tester to read the power of 19.86V 1.68A 33.32W.
Summarize the data into a table. Most mobile devices shake hands at 9V, game consoles and tablets shake hands at 15V, and laptops shake hands at 20V.
The histogram is drawn. The highest charging power is 33.32W for the MacBook Pro M2 2022, followed by 31.4W for the Lenovo Xiaoxin Air 14 laptopportable sourceIt has a good charging experience for laptops and other high-power devices, and the charging power of mobile phones can be in the range of 9-27W.
USB-A1/A2
Connect the iQOO 11S mobile phone to the USB A port of the 35W 20000mAh power bank, and use the POWER-Z KM003C tester to read the power of 8.9V 1.93A 17.15W.
Connect the Huawei Mate 40 Pro mobile phone to the USB-A port of the 35W 20000mAh power bank, and use the POWER-Z KM003C tester to read the power as 8.2V 2.49A 20.41W.
Summarize the test data to the table, and you can see the 9V and 5V voltage gears of the tested mobile phone device.
The histogram is drawn. It can be seen from the figure that since the USB-A interface is compatible with the SCP fast charging protocol, the charging power of Huawei Mate 40 Pro is 20.41W, followed by that of iQOO 11S mobile phone, which is 17.15W.
Input/output test
The MacBook Pro laptop and Meizu 20 Pro mobile phone are charged through the Type-C and USB-A1 ports of the 35W 20000mAh power pack, and the charging power is 13.8W and 6.5W respectively.
The MacBook Pro laptop, Meizu 20 Pro mobile phone and Nubia Z30 Pro mobile phone are charged through the Type-C, USB-A1 and USB-A2 ports of the 35W 20000mAh mobile phone, and the charging power is 13.8W, 5.8W and 7W respectively.
The charging and discharging test of the 35W 20000mAh mobile phone with moving speed was carried out through the 140W charger, Meizu 20 Pro mobile phone and Nubia Z30 Pro mobile phone. The output power of the charger terminal was 14.18W, and the input power of the mobile phone terminal was 6.2W and 6.4W.
Full charge test
For the whole process test of this 35W 20000mAh charger, use the 65W charger to charge it. The whole process test is carried out in a 25 ℃ thermostat. The whole process of charging is as follows.
Connect the power supply and shake hands with 20V voltage. The power is stable at 33.6W and the charge lasts for 1 hour and 21 minutes;Then the power drops to 20W in a "step" manner and continues to charge until the second hour and 45 minutes;Then the power slowly drops until it is fully charged. The whole charging process takes about 3 hours and 34 minutes.
The broken line chart is drawn. It can be seen that when using the SHI-SPEED 65W charger to charge the SHI-SPEED 35W 20000mAh power bank, it takes 1 hour and 14 minutes to charge to 50%, 2 hours and 12 minutes to charge to 80%, and 3 hours and 34 minutes to charge to 100%.
Output efficiency
The output efficiency is an important factor to measure the quality of the power bank. The power bank's efficiency is different when it outputs in different gears. The higher the output efficiency, the higher the conversion rate, the lower the heat. This time, we also tested the power bank's output efficiency in different gears.
First, let the power bank continuously output at 5V3A 15W, and finally end at 4 hours and 20 minutes;The actually released battery energy is about 60.28Wh, so the efficiency of the power bank when outputting at 5V3A 15W is about 60.28/66.6=90.51%.
Then let the power bank continuously output at 9V3A 27W, and finally end at 2h 26min;The actual discharged battery power is about 62.5Wh, so the efficiency of the power bank when outputting 9V3A 27W is about 62.5/66.6=93.84%.
Then let the power bank continuously output at 12V2.91A 35W, and finally end at 1 hour and 48 minutes;The actual discharged battery power is about 61.41Wh, so the efficiency of the power bank when outputting 12V2.91A 35W is about 61.41/66.6=92.21%.
Then let the power bank continuously output at 15V2.28A 35W, and finally end at 1 hour and 38 minutes;The actual discharged battery power is about 55.66Wh, so the efficiency of the power bank when outputting 15V2.28A 35W is about 55.66/66.6=83.57%.
Finally, let the power bank continuously output at 20V1.75A 35W. Due to the built-in temperature overheat control protection of 35W 20000mAh moving speed, the power bank finally stopped discharging at 1h 46min;The actual discharged battery power is about 61Wh, so when the power output of the power bank is 20V1.75A 35W, the efficiency of the power bank is about 61/66.6=91.59%.
Discharge temperature test
At 20V1.75A 35W constant power for 30 minutes, the maximum temperature on the front of the power bank is about 51.7 ℃.
The maximum temperature on the back of the power pack is about 47.6 ℃.At this time, touch the power bank with your hand and feel warm. The highest temperature is concentrated on the USB output port.
Summary of charging head network
The moving speed 35W 20000mAh power pack adheres to the simple style in the appearance design, with the surface fine grain sanding treatment, which is exquisite and does not hurt the hand;It has three USB ports: 1 * Type-C+2 * USB-A. Type-C port can support input and output functions. At the same time, an additional 1 * Micro charging port is added, allowing users to have more charging options.
In terms of charging performance, the Type-C port of the 35W 20000mAh power bank supports 35W power bidirectional fast charging, and the USB-A port supports 22.5W output.In the compatibility test, it is measured that it can last for mainstream mobile phones, tablets and computer devices. At the same time, the USB-A port supports the SCP fast charging protocol. For Huawei mobile phone users, the charging experience will be upgraded again.
In addition, use the Hassle 65W charger to access the Type-C port to charge the Hassle 35W 20000mAh power pack, which takes 3 hours and 34 minutes to fully charge;In the output test stage, except for the 15V voltage range, the charging efficiency at 5V, 9V, 12V and 20V voltage ranges is more than 90%, up to about 93.84%, and the energy conversion efficiency is higher.In addition, the temperature performance is excellent. Even if the maximum power is full load for half an hour, the maximum shell temperature is 51.7 ℃. The temperature in daily use will be lower than the temperature in full load test, more durable and safer.
Speed shifting 35W 20000mAh power bank continues the high quality and high efficiency output capability of speed shifting charger, and realizes the upgrade to 30-35W power based on the capacity of 20000mAh. With faster charging speed and competitive price, the same type of products meet the user's travel charging needs, and open a new charging era.
