I replaced my sluggish Cat42H with an iPhone 15 four weeks ago. That means a much faster phone that makes me use it more but also something like 1000mah less in battery. I ran into situations where I was afraid that I couldn’t unlock the car to return home in the evening.
This thing completely solves this problem. It surely comes with a weight penalty, but I find it really worth it.
I don’t have comparisons or long term experience, but my perception is really positive, especially in terms of capacity, charging speed and practicability.
