According to Digital Chart Station, HUAWEI is working on a 90 W wired fast-charging system that is allegedly intended for smartphones.
HUAWEI currently has a 66 W fast charger that was previously introduced with the HUAWEI Mate 40 Series. The fast charge feature is also available on the new nova 8i. The upcoming P50 series is expected to come with this charger, though nothing has been officially confirmed yet.
It was only last year when HUAWEI claimed that it has tested 120 W and 200 W fast-charging technology but did not launch it due to battery capacity concerns.
There is still no official news from HUAWEI yet so stay tuned for more details on the 90 W fast-charging.
