I just want to summarise briefly: For just under 100 francs, people buy a 1460mAh battery that charges wirelessly, i.e. MUCH less efficiently, even though they could have a 20,000mAh Varta powerbank for 36 francs, for example? The voltage, which is almost twice as high, is less than a small droplet on a red-hot stone. At the end of the day, you are paying 40 times as much for the same power. 40 TIMES AS MUCH.

Accepted Answer

Finally, someone who explains it to me properly. I hadn't even thought about it before 😂🤣. 
For me, the MagSafe is not a power bank in the classic sense. I use my smartphone to control my
my insulin pump. This requires that the battery of my smartphone always has power. When I am on the road for a long time 
MagSafe becomes a practical reserve that is light, magnetic and wireless. I can stow it anywhere and 
it doesn't pull down my jacket pocket. For me, it's the optimal solution for my needs.

Answer

Exactly. And that's okay and our decision. The bottom line is that I bought it because it had the Magsafe, and the other ones I always misplace and forget to charge. This one, oddly enough, doesn't, and I don't need a cable to charge my phone, it's small and fancy, and it still doesn't take more than 30 mins for the phone to be over 80%. But thanks for your mathematical calculation, which now affects our past choices and future ones. Android person, I guess.
