oppo45w and 50w wireless chargers have some differences in output power.
45w and 50w wireless charger if the output voltage is the same, then its rated output current will have a certain difference, the latter's rated output current is larger than the former, when charging the same electrical appliances, the time will be relatively short.

Since the power difference between 45w and 50w wireless chargers is not particularly large, if the output voltage is the same, generally speaking, it is basically universal.
