The 15W fast charge is currently at the second-to-last charging level,
At present, only 10W is less than 15W, up there are 18w, 20w, 30w, 33w, 50w, 60w, 65w, 66w, 67w, 68w, 90w, 120w and 150w, 165w next year, from these you can see what level 15w is currently in, 15W is only able to use the level. The charging speed is obscenely slow, and I can't stand 15W charging speed anyway
Now the common 65w, up to 120w have. So 15w is low now
At the level of a few years ago, it is now fast charging to 40w, and even Apple, which has been criticized for slow charging, has 20w fast charging
