At the end of last year, a Huawei 5G digital mobile phone with a suspected Mate Xs model TAH-AN00m passed 3C certification and was produced by Huawei Machinery Co., Ltd. The first certification was issued on December 26th, and its power adapter supports up to 65W output. The new Huawei 65W charger weighs about 92 grams, while the official weight of the old model is 160 grams, which means the weight of the new model is only 57.5% of the old model.At present, Huawei has equipped the new MateBook 13/14 2020 series laptops with a 65W pocket charger, with an official weight of 160 grams, which means it is still the old model. The new adapter is likely to debut the Huawei Mate Xs.At present, the Huawei MateBook 13/14 comes with a 65W charger that also supports super fast charging for phones such as the Huawei Mate 30 Pro. If you are using a Huawei device, only this charger will be sufficient in the future.
