Can I use a non-standard charger or data cable to charge my phone?

Yes, you can use a non-standard charger or data cable to charge your phone. However, the following issues may occur due to different charging specifications and protocols:

1. Slow charging speed: Chargers or data cables of other brands are not designed in accordance with Huawei phone standards. As a result, the charging power may not reach the maximum power supported by Huawei phones, or Huawei's fast charging protocol may not be supported, resulting in a slower charging speed. For example, the maximum charging power supported by the HUAWEI Mate 30 is 40 W (10 V 4 A). If a 5 V 2 A charger of another brand is used, or the charger does not support the Huawei fast charging protocol, the charging output cannot reach 40 W.
2. Security risks: Charging devices of legitimate manufacturers are strictly controlled in terms of quality and security. While some unbranded chargers in the market are able to charge mobile phones, they may bring security risks, or even severe damage. It is recommended that you purchase a charging device from a legitimate manufacturer.
