Buying a power bank for my 2020 MacBook Air (intel i5).

Hey,

So I want to buy a power bank for my MacBook Air, I'm a bit confused on the mAh of the bank as I'm not sure on the specifics of battery of the laptop. If I go to to About This Mac -> System Report -> Power , it shows that the capacity is 3680 mAh but if I check the same on the terminal using the command

```

ioreg -l -w0 | grep Capacity

```

it shows that the "Design capacity = 4381" , "max capacity = 3680" , "current capacity = 3508" and " capacity = 4032" .

I'm very confused on what type to choose as I do not want to damage the batter of the system, if you could please help me out, it would be lovely. Thank you.

You can use literally any USB-C power bank. Usually, the greater its capacity, the better it is and the more it costs.

Ideally, use one capable of delivering at least as much power as its power adapter (30W). More or less than that won't damage anything.
