Question about Huawei HW-100400E00 Super Charger

Well, it could be different revisions, it's hard to answer. But, I would not recommend this charger.

Today it works better, namely with so-called GaN chargers, which consume less power, get less hot and perform better. This model is hardly bigger, has the same power and can even charge two devices with a charging cable:

Baseus GaN Mini Wall Charger (45W, Quick Charge 4.0, Power Delivery 3.0)

Also works with Huawei devices without any problems :).
