Charging Compatibility Test
The compatibility test can clearly show the charging situation of each interface of the power bank for various devices. BHDChina will use dozens of devices to test with the power bank, presenting real test data to readers.
USB - C1
Connect the Lenovo Legion Y9000P to the USB - C1 port of the power bank. The measured power is 20.15V 6.62A 133.38W.
By drawing a bar chart, it can be seen that the device with the highest charging power is the Lenovo Legion Y9000P, which shakes hands with a proprietary protocol, with a power as high as 133.38W. Followed by the Huawei MateBook X Pro, with a power of 125.84W. For mobile phones, models that are compatible with the PPS protocol can obtain a relatively high charging power. For example, the iQOO13 and RedMagic 9S Pro + shake hands with the 5A PPS fast - charging protocol, both reaching very high charging powers. The charging powers of other mainstream models are all in the 10 - 40W range. Overall, the compatibility of the C1 port is excellent.
USB - C2
Connect the MacBook Pro 16 M4 Pro to the USB - C2 port of the power bank. The measured power is 19.98V 3.21A 64.15W.
By drawing a bar chart, it can be seen that the MacBook Pro 16 M4 Pro has the highest charging power of 64.15W. The USB - C2 port is similar to C1. Except that the maximum power is 65W, the handshake voltage and protocol are the same, and the compatibility is also excellent.
USB - A
Connect the Xiaomi 14 Ultra to the USB - A port of the power bank. The measured power is 8.87V 1.54A 13.63W.
By drawing a bar chart, it can be seen that the iQOO13 has the highest charging power of 17W, followed by the Huawei Mate70 Pro +, which shakes hands with the SCP fast - charging protocol, with a power of 17.01W. OPPO - series models have charging powers of around 16W, and the charging powers of other models are all in the 5 - 15W range.
Multi - port Output Test
When users have more smart devices that need to be charged simultaneously, it is necessary to clearly understand the power distribution of this power bank to charge the terminal devices more quickly.
When the two USB - C ports output simultaneously, the output power of USB - C1 is 61.19W, and the output power of USB - C2 is 57.44W.
When the three ports output simultaneously, the output power of USB - C1 is 63.44W, the output power of USB - C2 is 39.18W, and the output power of USB - A is 13.62W.
Digital Hybrid Charging Technology
The digital hybrid charging technology is an industry - first charging technology developed by Lenovo. Users can use the charger to supply power to the power bank, powering the output ports and the battery at the same time. When charging and discharging simultaneously, the built - in battery participates in the output, achieving the superposition of two types of electrical energy, which is the "digital hybrid charging technology".
The digital hybrid charging technology can transform the original adapter into a multi - port charger. While charging the power bank, a single port can quickly become a multi - port charger, achieving convenient storage.
When the power bank is charging, the input power is 62.52W. Through the superimposed output of the output port and the battery, the output power of USB - C1 is 86.32W.
When outputting to two devices, the input power is 62.36W, the output power of USB - C2 is 81.07W, and the output power of USB - A is 13.83W.
Temperature Test
A power bank is a conversion device, and there will be losses during the charging process, which are dissipated in the form of heat, so the power bank will generate heat. The thinkplus FLUXO High - Power Laptop Power Bank 140W 20000mAh supports a maximum output of 20V7A 140W. Place the power bank in a constant - temperature box at 25°C and collect the surface temperature of the power bank after 8 minutes of 20V7A load.
After 8 minutes of discharging, use a thermal imager to take a photo of the front of the power bank. It can be seen that the highest temperature is mainly concentrated in the component part, with a temperature of 52.8°C (due to the large impact of the reflective material on infrared, the infrared temperature can only show the hot spots, and the actual temperature is not that high), and the central temperature is 42.3°C.
Looking at the back temperature, it can be seen that the position of the highest temperature is the same as the front, with the highest temperature being 40.9°C and the central temperature being 37.3°C.
Summary
In terms of charging, although the power bank does not support PD 3.1, the USB - C1 port can provide a 20V 7A 140W output gear. It actually provides a charging power of about 133W for the Lenovo Legion Y9000P. It also has two sets of 5A PPS fast - charging protocols. The actual compatibility test shows good performance. Whether charging mobile phones, game consoles, tablets, or laptops, it has good fast - charging performance. For models that support the PPS protocol, the highest charging power can reach about 90W.
In terms of multi - port output, the output power of the two USB - C ports can reach 120W, and the three - port output can reach 116W, basically in line with the official data. It also supports continuous charging when unplugging and plugging multiple ports (only for mobile phones). In addition, the power bank is equipped with the industry's first digital hybrid charging technology, which can not only charge the power bank but also supply power to laptops and mobile phones, simply improving desktop tidiness and reducing the number of chargers on the desktop.
Overall, the performance of the thinkplus FLUXO High - Power Laptop Power Bank 140W 20000mAh is sufficient to meet the charging needs of most smart devices on the market. The 20V 7A output can provide power support for high - power devices such as laptops.
