Thin and Convenient

According to Casely, an online phone case store that we’d definitely heard of ten minutes ago and have deemed an entirely trustworthy source of information:

Fast forward to the iPhone 15, equipped with a substantial 3349 mAh battery, ready to meet your power-hungry demands. To guarantee that your iPhone 15 remains charged and at your service, a power bank with a charge capacity of about 5023.5 mAh is the ideal companion.

So, one of these power cards won’t fully charge your iPhone 15 (which isn’t even the most recent iteration of the iPhone). In fact, it won’t even come close.

But what about an older model? Like, say, the iPhone 8?

Ensure your iPhone 8 stays powered and ready to go, and select a power bank with the correct charge capacity. The iPhone 8, with its battery capacity of 1821 mAh, requires a power bank that can deliver around 2731.5 mAh to guarantee a complete charge.

Okay, wow.

So, even a phone that came out more than five years ago wouldn’t be fully charged by one of these.

We don’t have the breakdown for Android phones, but we imagine it’s not too different: you’re unlikely to get a complete charge with one of these.

But here’s the thing. Or, well, the things. Two things.

1. You get 4 of these. So, if you wanted to, you could carry multiple Charge Cards around with you (which wouldn’t be burdensome, considering their small size and easy-to-stash shape) to fully charge your newer phone. It would just involve swapping out banks a few times.

And also…

2. These aren’t really ‘fully charge your phone on a TransAtlantic flight’ power banks. They’re really more like ‘keep your phone alive when there’s a delay along your public transit route’ power banks. Especially because you can charge one up, put it in your wallet, and then forget about it until you need it.

Point is: these things are useful, even if one can’t fully charge a phone.

So get one! And by one, we mean four.
