Which iPhone 18w charger or 20w charger is more worth buying?

Let me talk about the conclusion first, iPhone 20W charger is more worth buying. However, this problem is no longer valid, because the iPhone 18W charger has been removed from Apple’s official website, and the original fast charger of Iphone12 can only be purchased with 20W or 30W.

In fact, the appearance and size of iPhone 20W charger and iPhone 18w chargerare exactly the same. They should be produced by the same mold. The word “20W” is added to the silk screen of iPhone 20W chargerto distinguish them.

The internal layout is almost the same, the circuits and components are slightly different, and the 20W hardware cost is lower. 20W is not a real replacement product of 18W, but an iterative optimization based on cost and technical solutions.

Let’s take a look at the charging efficiency. When the 20W charger was first released, the charging head net has done five kinds of charger charging tests. The data shows that there is no significant difference between 18W, 20W and 65W, but there is a big improvement over 5W and 12W.

1. If you have iPhone 18w charger in your hand, you don’t need to buy iPhone 20W charger fast charging, and the charging efficiency is limited.

2. If you have 5W and 12W in your hand, the mobile phone is used for daily and night charging, and there is no need for fast charging, so no additional purchase is required.

3. If you are a heavy mobile phone user and often need to recharge quickly, or use MagSafe induction charger, it is recommended to purchase a 20W charger.

If you need a cost-effective portable charger that is as small as possible, has high safety, and charges as fast as possible.
