Huawei mate40epro supports wireless charging, just place the phone on the charger to start charging. First, make sure your charger supports wireless charging and is Qi compliant.
Then, plug the charger into the power source and place the phone on the charger, making sure there are no obstructions between the two. The phone will automatically detect the charger and start charging. You can check the charging status on the phone screen, as well as the prompt after charging is complete. Note that wireless charging may be slower than wired charging, so it is recommended to start charging as early as you need to.
