That was what I was doing too. From one of the articles referenced on chargie.io [0] I learned battery lifetime is mostly about

- heat, which indeed potentially is lower with the small chargers, see Table 2

- keep between 35-75% charge level, see Figure 3.

With the astonishing battery life of the iPhone 13 under most daily use, even the _mini_, I will never go outside 35-75%. IOW I'm planning to buy a few Chargies, also leaving 1 or 2 in the car. That way I can use the iPhone 13 for another 6 years, like I did with the iPhone 6.
