1. First of all, the Huawei tablet and the OnePlus phone both use the usb charging standard, so the chargers between them can be used with each other. The Huawei tablet usually uses the usb type-c port for charging, and the OnePlus 50-watt charger also supports the type-c port.
2. The OnePlus 50-watt charger has an output power of 50 watts, which is enough power to provide the current and voltage needed to charge most tablets. Huawei tablets typically use 5v for charging and support 2a current input. According to the power formula p=vi, and 50w=5v*10a, we can conclude that the output power of 50 watts meets the charging requirements of Huawei tablet.
3. In addition, the OnePlus 50 Watt charger also uses some advanced fast charging technology, such as dash charging or warp charging, which can intelligently adjust the output power according to the needs of the device to achieve faster charging speed. While the Huawei tablet may not support these special fast charging protocols, it can still safely use the OnePlus 50 Watt charger for normal standard charging.
To sum up, a 50-watt charger can charge the Huawei tablet and provide enough power to meet charging needs. Make sure to use the original usb type-c cable for connection, and pay attention to whether the tablet is properly charged and whether the temperature is too high during charging.
No, the two charging protocols are different, can not be universal.
