使用移动电源USB-C2接口为MacBook Pro 16 M1 Max充电，使用 POWER-Z KM003C 测试仪读取笔记本端输入功率为 19.79V 4.64A 91.73W。
Connect the charger to the power bank and use the original charging cable, use the POWER-Z KM003C tester to read the power is 20.43V 4.55A 93.02W.
Summarizing the data into a table, we can see that most of the mobile phones in the test have a handshake voltage range of 9V, and tablets, game consoles and laptops can shake hands with 15V and 20V PD voltage ranges, and the actual test supports PD 100W output.
Draw a histogram, it can be seen that the highest charging power is Huawei MateBook X Pro, about 96.93W, basically running the power of the USB-C port, and the charging power of mainstream brand mobile phones is stable in the range of 15~30W, for some devices that support PPS fast charging protocol better, such as Samsung S24 Ultra, the power is higher, which can reach 43.45W; The overall performance of the C1 interface is excellent.
USB-A
After looking at the compatibility performance of the C port, let's finally take a look at the compatibility performance of the A port.
Connect the Huawei Mate60 Pro to the USB-A port and use the POWER-Z KM003C tester to read the input power of the phone as 8.23V 2.19A 18.01W.
Summarizing the data into a table, we can see that most of the models in the test have a handshake of 9V, and tablets, game consoles, and laptops can shake hands at 9V and 5V.
Drawing a histogram, it can be seen that the highest charging power is the Nubia Z30Pro, with a power of about 16.85W, and the power of OPPO series mobile phones is around 16W, and the rest of the models are in the 10-15W range.
Charge and put the test at the same time
Charging and discharging refers to charging the charger to the power bank, and then the USB-C port and USB-A port of the power bank to see if the power can be output, so that even if you take a single port charge on a business trip, you can also charge multiple devices.
Using the Apple 140W charger to charge the power bank and let the C port charge the iPhone15 Pro, you can see that when one person's C port is input, the other C port cannot be output.
Let's take a look at the input of the C port and the output of the A port, we can see that the output power of the A port is 17.93W, and the input is 47.48W.
When the C2 port is input to C1 and A port is output, you can see that the C1 port also cannot output, and the input C2 port is 93.16W, and the A port is 14.2W.
Multi-port simultaneous output test
When users have more smart devices that need to be charged at the same time, the power distribution of this power bank also needs to be clearly understood in order to charge the terminal devices more quickly.
When USB-C1 and USB-A output at the same time, the USB-C1 output power is 91.53W, and the USB-A output power is 18.91W.
When the three interfaces of the power bank are output at the same time, the power from top to bottom is: 11.9W, 17.67W, and 8.25W.
Charging is tested throughout the process
For the whole charging test of this Romax S10 130W flash charging stick, it will be charged with an Apple 140W charger, and the whole test will be carried out in a 25°C incubator, and the charging process is as follows.
After the power is turned on, shake hands with 20V voltage, and the starting power is stable at 92W and continue to charge for 5 minutes; The power then drops to 67W; At the 10th minute, the power drops to 47W, and then the power continues to drop until the end of charging, which takes about 48 minutes to charge.
Drawing a line chart, it can be seen that the Apple 140W charger is used to charge the Roma S10 130W flash charging stick, which takes 15 minutes to charge to 50%, 31 minutes to charge to 80%, and 48 minutes to charge to 100%.
Output efficiency
Output efficiency is an important factor to measure the quality of the power bank, the efficiency of the power bank in different gears is different, the higher the output efficiency, the higher the conversion rate, the smaller the heat, this time also tested the output efficiency of this power bank in different gears.
First, let the power bank continue to output at 5V3A 15W, and finally end in 2 hours and 6 minutes; The actual battery energy released is about 32.34Wh, so the efficiency of the power bank when it is output at 5V3A 15W is about 32.34/36=89.83%.
Then let the power bank continue to output at 9V3A 27W, and finally end in 1 hour and 12 minutes; The actual battery power released is about 34.08Wh, so the efficiency of the power bank when it is output at 9V3A 27W is about 34.08/36=94.67%.
Then let the power bank continue to output at 12V3A 36W, and finally end in 46 minutes; The actual battery power released is about 27.8Wh, so the efficiency of the power bank when it is output at 12V3A 26W is about 27.8/36=77.22%.
Then let the power bank continue to output at 15V3A 45W, and finally end in 43 minutes; The actual battery power released is about 33.16Wh, so the efficiency of the power bank when it is output at 15V3A 45W is about 33.16/36=92.11%.
Finally, let the power bank continue to output at 20V5A 100W power, due to temperature protection, the discharge will be interrupted in about 10 minutes, and the actual energy released is about 20.3Wh, at this time, the power display of Roma S10 130W flash charging rod is still about 68% left; The test instrument is in constant current and constant voltage mode, and cannot be downshifted, so the discharge is interrupted after temperature protection, and the input terminal can be self-adaptive in notebooks or other high-power equipment, and this situation will not occur.
Temperature test
With 20V 5A 100W constant power continuous output for 30 minutes, the maximum temperature of the AB surface of the power bank is about 40.7°C.
With 20V 5A 100W constant power continuous output for 30 minutes, the high temperature at the top of the power bank is about 45.4°C. At this time, touch the power bank with your hand, feel warm, and the highest temperature is concentrated in the metal material in the USB port, which is a normal phenomenon.
