My mobile phone can be charged with flash power bank. However, the charging protocol of this phone is the charging protocol of OPPO mobile phone, which is the vooc flash charging protocol. So you need to buy my own charging bank or OPPO brand charging bank. That should activate the flash charge. Or when you buy other brands of charging treasure, go to the special charging agreement to see if you can support the opening agreement of OPPO. If you can, you can't charge it fast.
1, About realme x original charger DC output is: 5V\/4A, power: 20W. If the USB output parameters you use are the same as above, it is OK, otherwise it is very useful. At present, the output power of the charging bank is 5V1A and 5V2A, and there is no fast charge for the time being, so it is not supported
