First of all, the most reliable and least worried is naturally Apple's own brand, which can be bought in the Apple online store, official website or offline store, after all, it is the best compatible with the iphone11. Secondly, you can consider buying some MFI certified brands, such as Green Link, purple rice, Bisi, etc., remember to buy from the official stores. Finally, choose some third-party brands, provided that PD fast charge protocol is supported, and in order to avoid battery damage, it is recommended to choose from the first two.
18 w
According to Apple's official website, the charging head power of the iPhone 11 is 18w fast charging head that meets the PD protocol. Although 10w is a slow charging head, charging the iPhone 11 will cause a slow charging speed and affect the battery life for a long time. I still recommend you use the official charger to charge the iPhone 11.
The iPhone 11 fast charge supports about 22W, but considering the following points, 20W is still recommended.

Although 20W is not much faster than 18W, it can still be a little faster

If you want to match MagSafe in the future, 20W output power is also more appropriate

If you buy Apple's official, 20W is ￥149, but 18W is ￥243, obviously 20W is more cost-effective.

Therefore, based on the above, it is recommended to buy 20W.
