Next, ChargerLAB will conduct a comprehensive test on the compatibility of the Xiaomi 100W GaN charger, evaluating its performance with a selection of Xiaomi phones, aiming to cover the majority of users' charging scenarios.

First up is Xiaomi’s highest-spec flagship, the Xiaomi 14 Ultra. Using the ChargerLAB POWER-Z KM003C, we recorded an output of 18.95V 3.43A, resulting in 65.01W.

The best performance was seen with the Redmi K70 Ultra, where the power reached 17.54V 5.15A, totaling 90.30W.
