The one I’ve used on my Samsung isn’t as fast as a wired power bank, but I don’t need to wrangle the cables like I do with the wired ones. I wouldn’t use a magsafe power bank to charge my phone from 0 (too slow). But leaving it attached gives me an extra couple of hours with just a little extra weight. Useful for things like conventions or travel.
My understanding is that Samsung uses an odd standard that means they can’t quick charge from Anker devices. That was at least true a few years back. Would be great to know if that’s changed.
