Compatibility Test

Next, let's do the charging compatibility test. 

Original Chargers

Charge with the original 120W charger, the power is about 18.21V 5.13A 93.36W.

Except for the 45W charger, the voltage of other chargers can reach about 17V, and the current is about 2 to 5A.

We have compiled the test results into a bar chart. There are no compatibility issues. The 120W charger reaches the highest power, which is 91.89W.

Third-party Chargers

We also used a variety of third-party chargers during the test. Let’s take a look at the results.

There is no compatibility issue. Most chargers can reach a voltage of 9V. The maximum current does not exceed 3A.

We have compiled the test results into a bar chart. Most chargers can reach a power of about 23W and 25W. The maximum power is 27.55W, and the minimum is 7.77W.

Power Banks

There is no compatibility issue. Most power banks can reach a voltage of 9V.

We have compiled the test results into a bar chart. The maximum power is 24.41W, and the minimum is 12.7W.

Full Charging Test

We use the original 120W charger to fully charge the REDMI K80 Pro. And put them into a 25°C (77℉) thermotank throughout the test.

The voltage is always around 18V. The charging curve can be divided into four parts. In the first part, the peak power stayed at 92W for the first 3 minutes. Then, the power gradually drops to 49W and 41W in turn. The final part begins at 29 minutes, the power slowly drops to almost zero. It takes 32 minutes to be fully charged.

From this chart, it can be seen that using the original 120W charger charges the REDMI K80 Pro to 50% in 13 minutes and 80% in 23 minutes. It reaches 100% in 32 minutes.

Temperature Test

We also recorded the highest temperature on the front and back after charging for 5 minutes, 10 minutes, and 20 minutes.

5 minutes Charging

After 5 minutes, the maximum temperature on the front is 38.8℃ (101.84 ℉).

The back is 40.2℃ (104.36 ℉). It can be seen that the heat is mainly concentrated in the area below the camera.

10 minutes Charging

After 10 minutes, the maximum temperature on the front is 39.5℃ (103.1 ℉).

The back is 40.8℃ (105.44 ℉). 

20 minutes Charging

After 20 minutes, the maximum temperature on the front is 39.9℃ (103.82 ℉).

The back is 41.0℃ (105.8 ℉). 

We turn the results into a curve. The temperature during charging is between 38.8-41.0℃. During the whole process, the temperature on the back side is 1-2℃ higher than that on the front side. When charging for 20 minutes, the temperature on the back is 41°C(105.8 ℉), the power is about 49W at this time, and it is warm to the touch.

Summary of ChargerLAB

The REDMI K80 Pro uses Qualcomm SM8750-AB Snapdragon 8 Elit and also supports IP68 dust/water resistant (up to 2.5m for 30 min). It is equipped with a 6000mAh battery and 120W wired fast charging.

In terms of compatibility, although third-party chargers can charge it, the power is not high. Therefore, it is recommended to use the original charger and cable to achieve higher power. Using the original 120W charger, the REDMI K80 Pro can be fully charged in 32 minutes. The maximum temperature during the entire charging process is only 41°C (105.8 ℉).
